Manage TSDB Settings

You can use the Paragon Automation GUI to configure the following time series database (TSDB) settings:

  • Select one or more TSDB nodes.
  • Dedicate all nodes or none of the available nodes as TSDB nodes.
  • Force TSDB setting changes in case of system errors.
  • Delete a node that has already been selected as a TSDB node.

For more information on TSDB, see Time Series Database (TSDB) Overview.

To manage TSDB settings:

  1. Select Administration > Ingest Settings.

    The Ingest Settings page appears.

  2. Click the Time Series Database tab to view the TSDB Settings tabbed page.
  3. From the TSDB Settings tabbed page, you can:
    1. Select a node from the TSDB Nodes list.

      The TSDB Nodes list displays nodes in the Paragon Automation installation that you can select as TSDB nodes. You can select more than one node from the TSDB Nodes list.

      To remove the default node, click X next to the name of the TSDB node.

      Note:

      Selecting, deleting, or dedicating TSDB nodes must be done during a maintenance window because some services will be restarted and the Paragon Automation GUI will likely be unresponsive.

    2. Set replication factor.

      Enter a value for the replication factor in the Replication Factor text box.

      The replication factor determines how many copies of the database are needed. Alternatively, you can use the arrows at the end of the text box to increase or decrease the value of the replication factor. The replication factor is set to 1 by default.

    3. Dedicate nodes as TSDB nodes.

      Click the Dedicate toggle to turn it on.

      All nodes are dedicated as TSDB nodes.

      Once you select a node as a TSDB node, you cannot run other microservices on those selected nodes.

      Note:

      You cannot dedicate a node as a TSBD node if the node is associated to a persistent volume (storage in a cluster).

    4. Ignore system errors by turning the Force toggle on.

      Click the Force toggle to turn it on. This ensures that all system errors are ignored when you replace a failed TSDB node from Paragon Automation.

      When a TSDB node fails and the replication factor is set to one, the TSDB data for that node is lost. In this scenario, the failed TSDB node must be removed from Paragon Automation.

      In instances where the TSDB node is not successfully removed, setting the Force toggle to true ensures that all system errors are ignored when you remove a failed TSDB node from Paragon Automation.

    5. Delete a node that has already been assigned as a TSDB node.

      To remove a node, click X next to the name of the TSDB node. The node is removed from the configuration settings when you deploy the new configuration.

  4. Do one of the following:
    • Click Save to only save the new configuration settings.

    • Click Save & Deploy to save and deploy the new configuration settings.
