To monitor application services running on the target VMs, plugins must be configured in the target VMs after the agent is installed.

After you have installed the agent, you can activate plugins to monitor application services. You can also reactivate plugins that must be monitored.

Prerequisite
  • If plugin activation requires the location of a file (for example, client certificates for SSL Trust) on the endpoint VM, the location and the files should have appropriate read permissions for the arcuser to access those files.
    Note: If the plugin displays a permission denied status, provide the arcuser with permissions to the file locations that you have specified during plugin activation.
  • Linux process activation for Pid files works only if the Pid file and its parent directories have read permission for Others.

Activate an Application Service

To monitor an application service, complete the following steps:
  1. From the left menu, click Environment > Applications. From the Applications panel, click Manage Telegraf Agents.
  2. Select the end point on which agent is running. You can use the filter functionality too. For example, filter by Agent Status > Agent Running.
  3. Expand the drop-down arrow against the VM on which the agent is installed. You see the Services Discovered section.
  4. From the Services Discovered section, select a service, click the vertical ellipsis and then click Add.
  5. Enable the application service from dialog box that is displayed on the right side.
  6. Enter the details for each instance that you add and click Save. For configuration details of each application, see Configuring Supported Application Services.

    Fields with a star are mandatory.

    For more information about the status details that appear against the application services, see the table called Status Details in Additional Operations from the Manage Telegraf Agents Page.

    To edit or delete instances of application services, click the Edit or Deleteoptions from the vertical ellipsis against application service you added. After the services have been added and saved, click the drop down arrow against the application service to view the list of services and their status.

The following special characters are permitted in the DB user field: '[]{} (),.<> ?:!|/~@#$%^&*- _ +=

You can provide DB name lists in the following format ['DBNAME_1', 'DBNAME_2', 'DBNAME_3'] where DBNAME_1, DBNAME_2, DBNAME_3 must not contain quotes such as ' and ".

Application Availability

When an application service is activated, the Application Availability metric is collected and displays if the application service is running on the VM or if it is down. 1 indicates that the application service is running on the VM and 0 indicates that the application service is down. This metric is available for all supported application services except JAVA application service.

For information about deactivating a service, see Deactivate an Application Service.
