Managing OpenSearch Dashboards Services

This appendix describes how you can manage the OpenSearch Dashboards service.

After you install OpenSearch Dashboards using the delivered DPK, you can add an OpenSearch Dashboards service, verify that the service is created, or delete the service.

Adding OpenSearch Dashboards as a Service on Linux

To add an OpenSearch Dashboards service:

  1. Open a terminal window, running as root.

  2. Change directory to OSK_INSTALL/setup:

    cd OSK_INSTALL/setup

  3. Run this command to add the service:

    ./psft-osd-service.sh --add --install_base_dir BASE_DIR

  4. Use one of these methods to verify that the service was added:

    • The output of the following ps command must show a running OpenSearch Dashboards process:

      ps -ef | grep node

    • Use the systemctl command:

      systemctl status opensearch-dashboards

      This should give an output with the status "active (running)," as shown in the following sample:

      opensearch-dashboards.service - OpenSearch Dashboards
Loaded: loaded (/etc/systemd/system/opensearch-dashboards.service; enabled; vendorpreset: disabled)
Active: active (running) since Wed 2023-03-29 07:37:14 UTC; 3s ago
Main PID: 122155 (node)
Tasks: 11 (limit: 190191)
Memory: 108.4M
CGroup: /system.slice/opensearch-dashboards.service

Verifying that the OpenSearch Dashboards Service Starts Automatically

After you install the OpenSearch Dashboards service and verify the installation, test to make sure the service starts automatically after you reboot the Linux server.

  1. Reboot the Linux server.

  2. Verify that the service has come up automatically.

    systemctl status opensearch-dashboards

    This should give an output with the status "active (running)," as shown in the following sample:

    opensearch-dashboards.service - OpenSearch Dashboards
Loaded: loaded (/etc/systemd/system/opensearch-dashboards.service; enabled; vendorpreset: disabled)
Active: active (running) since Wed 2023-03-29 07:37:14 UTC; 3s ago
Main PID: 122155 (node)
Tasks: 11 (limit: 190191)
Memory: 108.4M
CGroup: /system.slice/opensearch-dashboards.service

Removing the OpenSearch Dashboards Service on Linux

To remove the OpenSearch Dashboards service:

  1. Open a terminal window, running as root.

  2. Change directory to OSK_INSTALL/setup:

    cd OSK_INSTALL/setup

  3. Run this command to remove the service:

    ./psft-osd-service.sh --delete

  4. Use one of these methods to verify that the service was deleted:

    • The output of the following ps command should not include any OpenSearch Dashboards process:

      ps -ef | grep node

    • Use the systemctl command:

      systemctl status opensearch-dashboards
