Monitoring a Windows service with a changing name using Zabbix can be complex due to the changing service name. One approach is to use Zabbix’s LLD (Low-Level Discovery) feature along with scripting to dynamically discover and monitor the changing service.<\/p>\n\n\n\n

Method – 1<\/h2>\n\n\n\n

Here’s a step-by-step guide:<\/p>\n\n\n\n

Create a PowerShell Script:<\/strong><\/h2>\n\n\n\n

Write a PowerShell script that discovers the service name each time it’s executed. The script should output JSON in a specific format that Zabbix understands for LLD.<\/p>\n\n\n\n

\n\n\n
$services = Get-Service | Where-Object { $_.Status -eq \"Running\"<\/span> } | Select-Object -Property DisplayName\r\n\r\n$discoveryResult = @()\r\nforeach<\/span> ($service in $services) {\r\n    $discoveryResult += @{\r\n        \"{#SERVICE_NAME}\"<\/span> = $service.DisplayName\r\n    }\r\n}\r\n\r\n$discoveryResult | ConvertTo-Json\r\n<\/code><\/span>Code language:<\/span> PHP<\/span> (<\/span>php<\/span>)<\/span><\/small><\/pre>\n\n\n
\n\n\n\n
    \n
  1. Configure LLD Rule in Zabbix:<\/strong> In Zabbix, create a discovery rule that uses the PowerShell script to discover the running services. Define a LLD rule that processes the JSON output from the script.<\/li>\n\n\n\n
  2. Create Item Prototypes:<\/strong> Once services are discovered, you can create item prototypes based on the discovered services. These item prototypes will monitor the status of each service.<\/li>\n\n\n\n
  3. Create Trigger Prototypes:<\/strong> Similarly, create trigger prototypes for each item prototype to raise alerts based on the service status.<\/li>\n\n\n\n
  4. Configure Host:<\/strong> Set up a Zabbix host for the Windows machine you’re monitoring. Associate the discovery rule and item prototypes with this host.<\/li>\n\n\n\n
  5. Schedule Discovery:<\/strong> Configure a schedule for the discovery rule so that Zabbix runs the PowerShell script at regular intervals.<\/li>\n<\/ol>\n\n\n\n
    With this setup, Zabbix will dynamically discover the running services and monitor them accordingly, even if the service name changes on every restart.<\/p>\n\n\n\n
    Method – 2<\/h2>\n\n\n\n
    There are a few ways to monitor a service of Windows where the service name changes on every restart in Zabbix.<\/p>\n\n\n\n
    One way is to use the service.active<\/code> item key. The service.active<\/code> item key returns the name of the service that is currently running. So, if the service name changes, the Zabbix item will also change.<\/p>\n\n\n\n
    To do this, you can create a Zabbix item that monitors the service using the service.active<\/code> item key. In the Params<\/code> field, specify the name of the service that you want to monitor.<\/p>\n\n\n\n
    \"\"<\/figure>\n\n\n\n
    You can also create a Zabbix trigger that is based on the service.active<\/code> item. The trigger will be triggered if the service name changes.<\/p>\n\n\n\n
    \"\"<\/figure>\n\n\n\n
    Method -3 <\/h2>\n\n\n\n
    Another way to monitor a service of Windows where the service name changes on every restart in Zabbix is to use the service.info<\/code> item key. The service.info<\/code> item key returns the current name of the service. So, if the service name changes, the Zabbix item will also change.<\/p>\n\n\n\n
    To do this, you can create a Zabbix item that monitors the service using the service.info<\/code> item key. In the Params<\/code> field, specify the name of the service that you want to monitor.<\/p>\n\n\n\n
    \"\"<\/figure>\n\n\n\n
    You can also create a Zabbix trigger that is based on the service.info<\/code> item. The trigger will be triggered if the service name changes.<\/p>\n\n\n\n
    \"\"<\/figure>\n\n\n\n
    Finally, you can also use the service.state<\/code> item key to monitor a service of Windows where the service name changes on every restart in Zabbix. The service.state<\/code> item key returns the state of the service as a number. The following values are possible:<\/p>\n\n\n\n
      \n
    • 0: The service is not running.<\/li>\n\n\n\n
    • 1: The service is running.<\/li>\n\n\n\n
    • 2: The service is starting.<\/li>\n\n\n\n
    • 3: The service is stopping.<\/li>\n<\/ul>\n\n\n\n
      You can use the service.state<\/code> item key to create a Zabbix trigger that monitors the state of the service and generates an alert if the state changes.<\/p>\n\n\n\n

      Can you use regular expression in service name?<\/h2>\n\n\n\n
