Centralized User Management

Fusion has always provided a lot of value by enabling users to visualize status data from across their distributed Nagios deployments. It’s already a must-have for distributed environments and users who employ multiple Nagios Monitoring Solutions. Namely, Fusion’s ability to aggregate data from Nagios XI, Nagios Core, Nagios Log Server, and Nagios Network Analyzer systems and display it in custom dashboards and tactical displays. But one area of untapped potential has always been in serving as a platform for centralized management of other Nagios systems.

No longer is that the case! New in 2026R1 is the ability to copy users from one fused Nagios XI system to others with a few clicks, using the new Centralized Management menu. Although a humble first step, this new feature lays the foundation that will be used going forward to enable many more management capabilities in the future.

Managing Nagios XI Users with Nagios Fusion

As an added bonus, this addition also necessitated adding a new update users’ endpoint (PUT/system/user) to the Nagios XI API, so both solutions were enhanced in the process.

System Profile

You’ll also notice a new System Profile menu, which can be used to generate and download a profile with a single click. The System Profile zip contains a wealth of data about your setup and serves as an invaluable resource for troubleshooting and support.

Fixes

Several issues were also resolved in this release to make Fusion more stable and reliable:

• Server polling interval is now being updated properly.
• The Administrator and User Guides are now being displayed correctly.
• The ssl_hostname_verify parameter is now being passed when adding a server via the API.
• Users located in AD groups will now show up in the “Add User from AD/LDAP” page.

This article is a great resource for learning more about all of the capabilities:

If you’re not currently using Nagios Fusion and would like to take it for a spin, you can find the free, fully functional trial options:

The Admin Guide is another excellent resource for learning how to manage and get the most out of all of the capabilities:

Step 1: Prerequisites

• Python 3: The script uses Python, so make sure you have it installed so you can test your plugin as you develop it. It can be downloaded here.
• A code editor: To create this plugin I used VS Code, which can be downloaded here.

Step 2: Set Up the Python Script

Create a new Python file named check_route_hops.py and begin with a shebang line and essential import statements.

#!/usr/bin/env python3

import sys
import traceback
import argparse
import subprocess

def main():

if __name__ == "__main__":
    main()

Define the Nagios status codes to make the code more readable.

OK = 0
WARNING = 1
CRITICAL = 2
UNKNOWN = 3

Now, create a global variable for the command line arguments.

_args = None

Step 3: Parse Command-Line Arguments

The plugin should accept arguments to specify the target host, thresholds, and other options. Use Python’s argparse module to define and handle these arguments. This code should be placed within the main function.

parser = argparse.ArgumentParser(
 description='This script checks the number of hops to a target host using traceroute.'
 'You can define warning and critical thresholds for hop counts. '
 'If the host is unreachable with the default protocol (UDP) other protocols will be       tried.')
        
        # Define the arguments
        parser.add_argument('-H', '--host', required=True, type=str, help='Target host IP to check hop count')

        parser.add_argument('-t', '--timeout', default=3, type=int, help='Timeout duration in seconds for the check (default is 3)')

        parser.add_argument('-w', '--warning', required=False, type=int, help='Warning threshold for hop count')

        parser.add_argument('-c', '--critical', required=False, type=int, help='Critical threshold for hop count')

        parser.add_argument('-v', '--verbose', required=False, type=int, default=0, help=(
            'The verbosity level of the output. '
            '(0: Single line summary, '
            '1: Single line with additional information, '
            '2: Multi line with configuration debug output)'
        ))

        parser.add_argument('-p', '--protocol', type=str, default='UDP', help='First protocol to attempt for traceroute (default: UDP)')

        parser.add_argument('--debug', action='store_true', help='Enable debug mode')
        
        _args = parser.parse_args(sys.argv[1:])

Step 4: Implement the Traceroute Logic

Create a helper function to execute traceroute and calculate the number of hops to the host. Use subprocess.run to call the traceroute command. The stdout result of the command is then used to count the number of hops to the host. Different protocols are used by adding additional arguments to the command.

def get_route_hops(protocol):
    global _args

    try:
        result = None
        if protocol == "UDP":
            result = subprocess.run(['traceroute', _args.host], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True, timeout=_args.timeout)
        elif protocol == "ICMP":
            result = subprocess.run(['traceroute', _args.host, '-I'], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True, timeout=_args.timeout)
        
        # Count the number of hops (lines returned by traceroute)
        hops = len(result.stdout.splitlines()) - 1

        return hops if hops > 0 else 0

    except subprocess.TimeoutExpired:
        return 0
    except Exception as e:
        return 0

def get_route_hops(protocol):
    global _args

    try:
        result = None
        if protocol == "UDP":
            result = subprocess.run(['traceroute', _args.host], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True, timeout=_args.timeout)
        elif protocol == "ICMP":
            result = subprocess.run(['traceroute', _args.host, '-I'], stdout=subprocess.PIPE, stderr=subprocess.PIPE, text=True, timeout=_args.timeout)
        
        # Count the number of hops (lines returned by traceroute)
        hops = len(result.stdout.splitlines()) - 1

        return hops if hops > 0 else 0

    except subprocess.TimeoutExpired:
        return 0
    except Exception as e:
        return 0

Step 5: Combine Logic in the Main Function

The main function shall do the following:

1. Parse arguments.
2. Attempt traceroute on the specified protocol.
3. Fallback to alternative protocols if the specified protocol fails.
4. Compare the hop counts against the thresholds.
5. Build and print a Nagios status message.
6. Exit with the proper status code.

For testing, you can add debug statements that print out additional information if the –debug argument exists.

    # Find the number of hops to the host using different protocols    
    protocols = ['UDP', 'ICMP']    
    if _args.protocol in protocols:        
      protocols.remove(_args.protocol)       
      protocols.insert(0, _args.protocol)   
      
      hops = 0   
      used_protocol = _args.protocol  
      
      # Check the default protocol first   
      hops = get_route_hops(_args.protocol)  
      
      # If the default protocol fails, try the other protocols   
      if hops == 0:     
      for protocol in protocols[1:]:        
        hops = get_route_hops(protocol)
             
        if hops > 0:            
          used_protocol = protocol             
          break
        if hops == 0:       
          print("CRITICAL - Failed to determine hop count for all protocols")            
          sys.exit(CRITICAL)  
            
        # Set the status code based on the number of hops to the host    
        status_code = OK   
        if _args.warning and hops >= _args.warning:       
          status_code = WARNING   
        if _args.critical and hops >= _args.critical:       
          status_code = CRITICAL
          status_dict = {      
            0: "OK",       
            1: "WARNING",      
            2: "CRITICAL",   
          }
         
        # Build the status message   
        message = ''   
        if (hops == 1):      
          message = f"{status_dict[status_code]} - {hops} hop was counted to {_args.host}" 
        else:       
        message = f"{status_dict[status_code]} - {hops} hops were counted to {_args.host}"
         
        print(message)    
        sys.exit(status_code)

    # Find the number of hops to the host using different protocols    
    protocols = ['UDP', 'ICMP']    
    if _args.protocol in protocols:        
      protocols.remove(_args.protocol)       
      protocols.insert(0, _args.protocol)   
      
      hops = 0   
      used_protocol = _args.protocol  
      
      # Check the default protocol first   
      hops = get_route_hops(_args.protocol)  
      
      # If the default protocol fails, try the other protocols   
      if hops == 0:     
      for protocol in protocols[1:]:        
        hops = get_route_hops(protocol)
             
        if hops > 0:            
          used_protocol = protocol             
          break
        if hops == 0:       
          print("CRITICAL - Failed to determine hop count for all protocols")            
          sys.exit(CRITICAL)  
            
        # Set the status code based on the number of hops to the host    
        status_code = OK   
        if _args.warning and hops >= _args.warning:       
          status_code = WARNING   
        if _args.critical and hops >= _args.critical:       
          status_code = CRITICAL
          status_dict = {      
            0: "OK",       
            1: "WARNING",      
            2: "CRITICAL",   
          }
         
        # Build the status message   
        message = ''   
        if (hops == 1):      
          message = f"{status_dict[status_code]} - {hops} hop was counted to {_args.host}" 
        else:       
        message = f"{status_dict[status_code]} - {hops} hops were counted to {_args.host}"
         
        print(message)    
        sys.exit(status_code)

Step 6: Test the Plugin

Run your script manually to verify that your plugin functions as expected. Try different combinations of arguments to ensure everything functions as expected.

Here is an example of what you could run in your terminal:

python3 check_route_hops.py -H example.com -w 10 -c 20 -p ICMP --debug

But what if you could see issues coming and act before they cause real damage? That’s where network monitoring comes in.

In this article, you’ll see more examples that answer the question “Why is network monitoring important?” including specific industry examples of how network monitoring can keep your systems running smoothly.

What Is Network Monitoring?

Network monitoring gives you the key hints of when an outage might occur and, more importantly, how to prevent it.

Key Capabilities of Network Monitoring:

• Full visibility across hybrid and cloud-native setups.
• Automated, proactive alerts.
• Support for automation and self-healing systems.
• Centralized metrics, logs, and alerts.

Why is Network Monitoring Important?

Now that we understand what network monitoring does, let’s examine why it’s become essential for today’s IT operations. Here’s what tech leaders are looking at in today’s IT landscape, as well as how network monitoring addresses these challenges:

By implementing monitoring solutions, organizations can avoid costly downtime, gain visibility across complex environments, and maintain operational resilience.

Moving beyond theory, let’s see how real organizations put these monitoring principles into practice.

How Different Industries Use Network Monitoring

Organizations in every industry are using network monitoring to stay ahead:

Healthcare: Hospitals use log monitoring to maintain HIPAA compliance and keep patient systems online during updates or upgrades.

Aerospace: In aerospace, monitoring systems track spacecraft data to keep missions running smoothly, monitor flight systems to prevent crashes and equipment failures, and check engine health to fix problems before they cause delays.

Financial Services: High-volume transaction systems rely on monitoring and alerting to reduce fraud risk and performance lag.

With these industry applications in mind, choosing the right monitoring solution becomes crucial for achieving these results in your own environment.

Why Choose Nagios?

When selecting a network monitoring platform, you have several options to consider. Solutions like Nagios, SolarWinds, Datadog, Zabbix, and many others.

Why Nagios Stands Out:

• Proven Reliability: Nagios has a long-standing reputation for stability. When your monitoring can’t go down, you need something proven.

• Modern Features: Recent updates in Nagios XI 2024R2 include predictive alerting, REST APIs, log correlation, and hybrid environment support.

• Flexibility that Scales: Custom plugins, community extensions, and integrations with tools like Prometheus, Zabbix, Elasticsearch, and ServiceNow, which help build exactly what you need for your unique environment.

• Industry Trust: Used by leading organizations across aerospace, healthcare, finance, and government sectors for mission-critical monitoring.

• Cost-Effective Growth: Architecture that grows with your needs, avoiding high licensing fees.

Moving Forward

Outages and downtime are just some of the impacts of not having a proactive approach to network monitoring. Good monitoring doesn’t just alert you to problems; it helps you understand your environment. That way you can figure out where to focus your efforts, like spotting which systems are about to give you trouble or finding the best places to automate those repetitive tasks that eat up your day.

If you’re looking to improve your monitoring approach, there are a few ways to explore what’s possible. You could test Nagios XI in your own environment or schedule a demo with a Nagios expert about your specific challenges. And if you’re still asking yourself, “Why is network monitoring important?” and want to see more examples, review how other organizations have approached similar IT problems to see the real-world impact and stories.

This video provides a guided walk-through covering each step of the DHCP Server Wizard:

Monitoring DHCP Server with Nagios XI

1. Experience Frequent Network Outages

If your team regularly experiences network disconnections or unexplained outages, network monitoring is necessary. Frequently, these issues are caused by failed hardware, configuration problems, or capacity limitations. Without monitoring, you’re stuck guessing the problem that could have been caught early.

With no monitoring solution, you’re stuck in reactive mode. You might rush to resolve problems as they arise, but operations and users have already been impacted. The damage has already been done.

Think about it this way: every minute your network is down, your team isn’t just waiting around; they’re losing momentum, missing deadlines, and getting frustrated. Network monitoring transforms you from an emergency firefighter into a prevention specialist. Enabling you to be proactive and catch issues before they impact your operations.  

2. Complaints of Slow Performance

Do employees complain about slow emails, delayed file transfers, or extremely long loading times? Slow networks don’t just cause an inconvenience to your team and customers; they kill momentum and can even drain team morale. 

The real culprits behind slow performance:

• Bandwidth bottlenecks during peak usage.
• Network latency issues affecting cloud applications.
• Packet loss is causing delays.
• Overloaded network segments are struggling to keep up.

Network monitoring provides the data needed to pinpoint exactly what’s causing the slow performance. More importantly, you can predict trends that help with network growth and sustainability, preventing any slowdowns in the future.  

3. Blind Spots in Network Security

In today’s landscape, networks are under constant security challenges. Not knowing what is happening behind the scenes is like leaving your front door wide open to cybercriminals.

Network monitoring gives you the visibility to spot these security threats as soon as they happen, not after the damage is already done.

For compliance-heavy industries: Custom reports and tailored queries make passing security audits much easier. No more scrambling to prove you’re meeting requirements; the data is right there for you.

4. Growth Feels Like a Constant Emergency

Growing businesses often experience network performance issues when adding new users, devices, or applications. Without understanding current network capacity, every expansion can feel like a gamble.

Here’s the thing: network monitoring provides the historical data and trend analysis you need to make smart growth decisions. Instead of reactive emergency fixes, you can plan proactively and ensure your network scales with your business.

5. You Can’t Answer Basic Questions About Your Network

If someone walked into your office right now and asked about your network’s current state, could you give them concrete answers? If you’re stuck with responses like “I think it’s fine” or “probably okay,” you’re running your business blindly. Lack of visibility makes it impossible to optimize your network resources, troubleshoot issues, or demonstrate network reliability.

If you answered “I don’t know” to any of these questions, that likely means you’re making decisions off guesswork, not data. Network monitoring can transform this uncertainty into actionable insights.

The Cost of Waiting

Delaying network monitoring implementation often results in:

• Increased downtime: Every outage costs money, productivity, and customer trust. The longer you wait, the more expensive solutions become.
• Reduced productivity: Slow networks don’t just frustrate employees and diminish their productivity; they reduce business output and customer trust.
• Security vulnerabilities: Threats you can’t see are threats that you can’t stop.
• Higher Costs: Emergency fixes and reactive solutions are always more expensive than planning ahead.
• Poor Decision Making: Without data, you’re blindly making important infrastructure decisions.

Taking Action

Recognizing these signs is the first step toward transforming your network from a source of frustration into a competitive advantage. The earlier you address these issues, the more you can minimize their impact on your business operations and team morale.

Why Nagios?

Nagios provides comprehensive network monitoring solutions that address all these warning signs. The Nagios suite offers the visibility and proactive capabilities you need to transform your infrastructure from reactive firefighting to strategic network management.

Whether you’re dealing with frequent outages, slow performance, security blind spots, growth challenges, or simply need better visibility, Nagios has the tools to help you get back in control.

NCPA v3 Support for Deploy Agent

The Auto Deployment feature, which enables you to push NCPA (the Nagios Cross Platform Agent) to remote hosts right from the Nagios XI UI, previously only supported NCPA v2, an older version of the agent. Now you can also deploy NCPA v3, the latest version, with the tool. This enables you to take advantage of all of the updates that went into v3, while still leveraging the convenience and centralized control of Auto Deployment.

Introducing Premium

In Nagios XI 2024R2, we’re introducing a new Premium Features model. Premium Features are a benefit of active license Maintenance.

SNMP capabilities are ubiquitous across the critical elements of your deployment, and the protocol quantifies countless metrics that can be monitored to keep an eye on the status and performance of both legacy and modern equipment in your infrastructure.

Active SNMP checks, where Nagios XI polls OIDs (Object IDs) for data, tend to be fairly accessible, especially using built-in tools like the Network Switch and Router Wizard. But what about SNMP traps? As powerful as this passive approach to SNMP monitoring is, providing rapid results when events occur, traps can be difficult to configure for monitoring. That’s where NXTI (the Nagios XI SNMP Trap Interface) comes in.

Without NXTI

On the plus side, Nagios XI is fully capable of monitoring, alerting, and reporting on SNMP traps even in the Standard edition. However, trap definitions are handled on the command line with flat text files, which adds an additional layer of complexity to an already complicated monitoring method. If you’re a command line wiz and know traps well, this may not be a roadblock, but for everyone else the value of NXTI is huge, making trap monitoring more accessible.

The NXTI Advantage

NXTI provides a way to manage your trap settings right from the Nagios XI GUI, enabling you to:

• View, Add, Edit, Copy, Delete, and Disable trap definitions.
• Configure passive checks based on traps.
• View and Delete received trap logs.
• Search and sort both trap definitions and received trap logs.
• Monitor the snmptt process.
• Locally test snmptrapd/snmptt functionality.

Quite simply, NXTI helps you go from this:

To this:

Note that in order to monitor incoming traps that match your trap definition, you’ll need to check the Enable Passive Service Setup checkbox.

You can then run the SNMP Trap Wizard to begin monitoring the traps. If for some reason you do not see status results in the SNMP trap service you set up for traps you’ve received, check in Admin > Monitoring Config > Unconfigured Objects, in case there is a mismatch between the IP/FQDN you set in Nagios for the target host and the IP/FQDN contained in the trap.

The Advanced Section

The Advanced tab of NXTI (at the top right of the NXTI menu) provides a variety of useful functions, including the ability to add an example trap definition, to send a test trap, and even to send a custom test trap for more specific testing of trap features and functions. It also provides a way to view the Unknown Trap Log, which lists any traps XI receives that don’t have a matching trap definition.

The Immense Scale of Apple’s IT Landscape

Imagine the sheer volume of devices, servers, networks, and applications that power Apple’s operations:

• Data Centers: Thousands of servers, storage arrays, and networking equipment supporting iCloud, Apple Music, the App Store, and other online services.
• Retail Stores: Complex networks, point-of-sale systems, and inventory management tools across hundreds of locations worldwide.
• Corporate Campuses: Extensive internal networks, development servers, and communication systems supporting a global workforce.
• Manufacturing and Logistics: Sophisticated systems tracking production, shipping, and distribution of millions of products.
• Customer Support: Infrastructure supporting vast call centers and online support platforms.

Monitoring such a diverse and geographically dispersed environment effectively is a monumental task. This is where a comprehensive and scalable solution like Nagios XI shines.

Nagios XI: The Backbone of Operational Excellence

Nagios XI provides a powerful, unified platform for monitoring an organization’s entire IT infrastructure. Its benefits directly address the challenges faced by large enterprises like Apple:

1. Proactive Problem Detection and Resolution: Nagios XI continuously monitors critical systems, applications, and network devices for performance issues and errors. Intelligent alerting ensures IT teams are immediately notified of potential problems, allowing for rapid response and minimizing downtime. This proactive approach is crucial for maintaining the “always-on” experience Apple users expect.
2. Comprehensive Visibility and Control: Nagios XI’s intuitive dashboards offer a centralized view of the entire IT landscape, providing insights into system health, performance trends, and potential bottlenecks. This holistic perspective is invaluable for understanding interdependencies and making informed decisions. Different teams within Apple can even tailor dashboards to display the metrics most relevant to their specific roles, enhancing efficiency and focus.
3. Scalability to Meet Enterprise Demands: Nagios XI’s architecture allows for distributed monitoring, enabling it to scale across multiple data centers and geographically dispersed locations. This is vital for a company with a global footprint like Apple. Furthermore, the vast Nagios Exchange offers thousands of community-developed plugins, allowing Apple to monitor virtually any device, application, or service, from macOS servers and network devices to custom-built internal applications.
4. Performance Optimization and Capacity Planning: Nagios XI collects historical performance data, enabling IT teams to analyze trends, identify recurring issues, and optimize resource allocation. By analyzing past usage, Nagios XI can also help predict future resource requirements, allowing Apple to make strategic investments in infrastructure before demand overwhelms existing capacity. This foresight is critical for managing rapid growth and new product launches.
5. Security and Compliance: Continuous monitoring helps identify unusual activity or performance deviations that could indicate a security breach or misconfiguration. Nagios XI also provides detailed logs and reports, assisting with compliance audits and ensuring that IT operations adhere to strict security policies.

The Apple-Nagios Connection (Illustrative Example):

While Apple does not publicly endorse its specific monitoring tools, the principles of effective IT management are universal. For instance, Nagios XI’s ability to monitor macOS systems via SNMP and NCPA agents allows for deep insights into the performance of Apple’s own hardware and software. Imagine a scenario where:

• A sudden spike in CPU usage on an iCloud server is detected by Nagios XI, triggering an alert.
• IT operations quickly identify the root cause—a misbehaving service—and remediate it before users experience any service degradation.
• Performance graphs in Nagios XI confirm that the server has returned to optimal operation.

This seamless, proactive approach is what allows Apple to maintain its reputation for delivering high-quality, reliable products and services.

Conclusion:

In an era where technology drives every aspect of business, organizations like Apple understand that their success hinges on the uninterrupted and optimal performance of their IT infrastructure. Nagios XI provides the robust, scalable, and intelligent monitoring capabilities necessary to achieve this. By offering comprehensive visibility, proactive alerting, and powerful analytical tools, Nagios XI empowers enterprises to not only react to issues but to anticipate and prevent them, ultimately safeguarding their operations and enhancing the user experience. For any organization aiming for operational excellence in the digital age, the strategic adoption of a solution like Nagios XI is a clear path to achieving and maintaining a competitive edge.
