Monitoring using Linux Services Monitor

Introduction

Linux Services Monitor helps you track the status of the Linux services in your environment. The main purpose of using the Linux Services Monitor is to observe the application availability and faster detection of failures. You can check the status using a return code with one of the following values:

THE Linux services monitor tracks the status of Linux services by observing application availability and detection of failures. The status uses one of the following return codes:

• 0: Running
• 1: Stopped

The agent raises an alert if the original status does not match the return code.

To manage Linux services, a Linux services monitor can be added using Setup > Monitoring > Templates > Other Monitors. For more information, see Validate Template.

After applying the template to a device, the template can be validated if it is assigned to a resource.

Creating Linux services monitors

To create a Linux services monitor:

1. From All Clients, select a client.
2. Go to Setup > Monitoring > Templates.
3. From TEMPLATES, click +Add. The monitor template appears.
4. From MONITOR TEMPLATE, provide the details for the following parameters and click Save:
   • Select Template Scope: The partner template or client-specific template. For the client-specific template, select the client.
   • Collector Type: The application type used to gather the information. Select the agent.
   • Applicable for: The type of the application.
   • Template Name: The name of the template.
   • Description: The summary of the template.
   • Generation: The generation that the template belongs to. For example: Generation 2.
   • Tags: The user-defined tags used for enhanced filtering.
   • Prerequisites: The essential prerequisites to consider while monitoring using a template. For a Windows template, as an example, check the SQL services while monitoring SQL parameters.
   • Status: The active or end-of-life templates.
   • Notes: Additional information to add to the template.
   • Template Family Name: The category that applies to the application. Examples include: Windows server, storage server, and network server.
   • Deployment Type: Select one of the following methods to apply the template to resources:
     • Custom
     • Optional
     • Standard
5. After configuring the template, go to Other Monitors and click +Add. The other monitors screen appears.
6. From the options displayed in Monitor Type drop-down, select Linux services monitor. The Linux services monitor screen appears.
7. From Linux Services Monitor section, click Add to provide additional detailed parameters.
   Click Add and Remove to increase or decrease the following settings:
   • Frequency: The intervals used to monitor the services. The recommendation is 15 minutes.
   • Alert: Select Alert to receive alerts in the event of any match.
   • Apply Availability Monitor: Select the checkbox to show the availability of the monitors.
   • Priority: The priority of the alert.
   • Articles: The articles that you can add.
   • Service Name: The name of the service to monitor.
   • Return Code: The return code to check the service status command. The Agent raises an alert if the return code does not match.

For example, the SSH service is inactive and you provide 0 in the return code field. The Agent after monitoring raises a critical alert when the original service status does not match with the return code. An OK alert is sent if the return code matches.

For example, the SSH service is inactive and a 0 is entered in the return code field. After monitoring, the agent raises a critical alert when the original service status does not match the return code. Otherwise, an OK alert is sent if the return code matches.

After adding a template with a Linux services monitor, assign the template to a device to start monitoring.

Managing Linux services monitors

Linux services monitor details can be viewed and modified when added to a template. Perform the following actions to manage the Linux services monitor:

• Edit: Click the template name displayed on the templates screen to modify the monitor details.
• View: View the monitor details in the templates screen. Click the arrow next to the template name to view the Linux services monitor added to the current template.

Validating templates

The graphical data is displayed for each name configured in the Linux services monitor. Monitor graphs can be viewed under Infrastructure > Resources > Device Details > Metrics. The graph displays the monitor details using ghe return code of the services.

Linux services monitor alerts

Critical alerts are sent while monitoring the services and the status does not match the return code. View the alerts in the Alert browser. Examine the alert description to verify the last modified time.
