Hi Team,

We had requirement that how the end user get notified in case the filebeat and Elasticsearch service get stopped.

Note:- Both is configured through systemctl process.

To notify users if the Filebeat and Elasticsearch services stop when configured through systemctl, you can use the systemd service unit configurations to set up service monitoring and notifications. Here are the steps you can follow:

  1. Ensure Startup Timeout is Adequate:

    • Update your systemd configuration to ensure that the services have enough startup time. Versions of systemd prior to 238 do not support extending startup timeout, so you may need to manually set this.
    • Example configuration snippet:
    [Service]
TimeoutStartSec=900

    Upgrading to at least version 238 of systemd can prevent premature termination:

  2. Configure Restart Options:

    • Configure systemd to automatically restart Filebeat and Elasticsearch in case they stop unexpectedly. This can be done using the Restart directive in their respective service unit files (e.g., filebeat.service and elasticsearch.service):
    [Service]
Restart=always
RestartSec=10

  3. Set Up Notifications Using systemd:

    • To send notifications, you can use systemd's on-failure actions. systemd supports various methods for notifications, including emails, custom scripts, or integrating with monitoring tools like Nagios or Prometheus.
    • Example using email notifications via sendmail:
    [Unit]
OnFailure=notify-admins@%n.service

[Service]
[Install]
WantedBy=multi-user.target

    Then create the notify-admins@.service unit file:

    [Unit]
Description=Notify administrators about %i service failure

[Service]
Type=oneshot
ExecStart=/usr/sbin/sendmail admin@example.com

    Replace admin@example.com with the appropriate email address for notifications.

  4. Alternative Notification with Monitoring Tools:

    • Integrate with monitoring tools that can watch the status of the services and send notifications accordingly. Tools like Nagios, Prometheus, and Elasticsearch Watcher can be configured to monitor system services and send notifications when services stop.

Here are the relevant references from internal documents:

Sources:

  • Configuring Filebeat: configuring-filebeat.asciidoc (internal document)
  • Systemd Startup Timeouts and Configuration: systemd.asciidoc (internal document)
  • Watching the Status of Elasticsearch: example-watch-clusterstatus.asciidoc (internal document)

These configurations should help in setting up notifications for service stoppages.

@rtwolfe94022 Thanks for quick response. I will explore and update on this.

@rtwolfe94022 After checking with customer, actually they want the SNMP alerts need to configure for Filebeat and Elasticsearch in case of any downtime.

Thanks,
