After you deploy and set up a standalone Log Insight node, you can deploy a new Log Insight instance and add it to the existing node to form a Log Insight cluster.

Log Insight can scale out by using multiple virtual appliance instances. This enables linear scaling of the ingestion throughput, increases query performance and allows for ingestion high availability. In cluster mode, Log Insight provides master and worker nodes. Both master and worker nodes are responsible for a subset of data. Master nodes can query all subsets of data and aggregate the results.

In the vSphere Client, note the IP address of the worker Log Insight virtual appliance.

Verify that you have the IP address or host name of the master Log Insight virtual appliance.

Verify that you have an administrator account on the master Log Insight virtual appliance.

Verify that you use a supported browser, see Minimum Requirements.

1

Use a supported browser to navigate to the Web user interface of the Log Insight worker.

The URL format is https://log_insight-host/, where log_insight-host is the IP address or host name of the Log Insight worker virtual appliance.

The initial configuration wizard opens.

2

Click Join Existing Deployment.

3

Enter the IP address or host name of the Log Insight master and click Go.

The worker sends a request to the Log Insight master to join the existing deployment.

4

Click the Click here to access the Cluster Management page link.

5

Log in as an administrator.

The Cluster page loads.

6

Click Allow.

The worker joins the existing deployment and Log Insight begins to operate in a cluster.

To add another worker, deploy a new Log Insight instance and add it to the cluster using the startup wizard.
