Viewing and Filtering the List of Managed Clusters

Use the Managed Clusters page to view the list of all clusters currently managed by Ops Director, along with their health status.

The columns displayed in the Managed Clusters tab are described in the following table.

You may export data from the Managed Clusters tab as a CSV (Comma Separated Values) file by clicking the Export icon in the upper right corner. The following rules apply:

You may then import the CSV file into other applications (such as Excel) for further processing or analysis.

A managed cluster may become disconnected from the Ops Director, either due to temporary network unavailability or because MarkLogic Server had stopped on the hosts comprising the cluster. In this case, the cluster's state cannot be determined by Ops Director, and hence the cluster is assigned the Unknown state.

For additional reasons why a managed cluster might be assigned the Unknown state, see Security and Database Dependencies of Managed Clusters.

You may filter the list of the managed clusters to view only those clusters that are currently in the Unknown state by selecting the Show only unknown checkbox.

Removing Unknown Managed Clusters from the List

You may remove a managed cluster that is currently in the Unknown state from the list of clusters managed by Ops Director. Perform the following steps:

1. Click REMOVE to the right of the cluster you want to remove from the list.

   

   The Remove button is enabled only for clusters that are currently in the Unknown state.

2. A confirmation box appears asking Do you wish to remove this cluster from the list of clusters managed by this instance of Ops Director? Click YES.

   

3. The cluster is removed, and the updated list of managed clusters is displayed by Ops Director.

   

Reconnecting a Managed Cluster to Ops Director

If you removed a cluster from the list of clusters managed by Ops Director, you may want to reconnect this cluster later on, such as when the issue that caused the Unknown state is resolved.

To add the cluster back to the list of clusters managed by Ops Director from the Admin Interface, perform the following steps:

1. Log into the Admin Interface on the cluster to be managed by Ops Director.
2. In the left menu, select Configure > Clusters.
3. Select the local cluster. The Edit Local Cluster Configuration page appears.
4. Select the Ops Director tab at the top of the page.
5. The Ops Director Setup page is displayed. Select stop managing this cluster.

   

   When you remove the cluster from the list of managed clusters in Ops Director, the cluster is not notified that it is no longer managed, because the connection between the cluster and the Ops Director is down at that point. Therefore, you must first update the cluster state by selecting stop managing this cluster from the Admin Interface.

6. On the Stop Managing this Cluster page, make sure the box to the left of Remove Ops Director Certificate Authority box is unchecked, then click ok.

   

   You may stop managing and start managing a cluster without re-importing a certificate to it, in case the cluster will be managed by the same instance of Ops Director.

7. The Server Restart page is displyed.The page informs you that MarkLogic Server is being restarted to load new Ops Director status configuration.

   

8. When the restart is completed, the Ops Director Setup page is displayed again. Select manage this cluster.

   

9. The Configure as a Managed Cluster page is displayed.
   • Enter the name of the host where your Ops Director application runs.
   • From the Ops Director Certificate Authority menu, select MarkLogic Ops Director Certificate Authority.

     You may optionally modify the level for log messages sent to Ops Director, as well as the frequency at which the metering data is collected.

     Click ok.

     

10. In Ops Director, select the CONSOLE SETTINGS tab. In the left menu under CONNECTIVITY, select Managed Clusters.

    Refresh the page. The updated list of managed clusters is displayed, with the newly reconnected cluster among them.

Setting Up Email Notifications

To set up Ops Director to notify you by email when a specific type of event occurs:

1. Make sure you have set up your SMTP relay. In the Admin Interface, navigate to Configure > Groups > Default. In the right pane, select the Configure tab. Make sure the smtp relay field contains the correct name and port of the SMTP relay host. If it needs to be changed, make sure to click ok at the bottom of the pane to save your changes.

   

2. Log into the XQuery console (port 8000) and submit the following query to update the From email address against the database OpsDirector and the server OpsDirectorApplication, replacing Test User and test-xdmp-email@marklogic.com with the name and email address from which the alerts are to come:

   xquery version "1.0-ml"; import module namespace cfg="http://marklogic.com/v1/opsdirector/config"     at "/common/config.xqy"; cfg:set-atomic-property("email-return-name", "Test User"), cfg:set-atomic-property("email-return-address", "test-xdmp-email@marklogic.com")

3. In the Ops Director interface, select CONSOLE SETTINGS. In the left menu, select Email Configuration. The Email Configuration page displays in the right pane.

   

4. Enter the Login and Password credentials for the the SMTP relay server configured in the Admin UI in step 1. Click SAVE to save the credentials.
5. To make sure the Ops Director email server is working correctly, click SEND TEST EMAIL. The SEND TEST EMAIL box displays.

   

6. Enter an email address to receive the test message and click OK. You will receive a test email message similar to the following:

   

To remove the account from Ops Director, click DELETE.

Setting up and Managing Alerts

The Alert Management page enables you to determine when email alerts are sent. To display the Alert Management page in the right pane, in the left menu, select Alert Management.
