After you deploy and set up a standalone VMware Aria Operations for Logs node, you can deploy a new VMware Aria Operations for Logs instance and add it to the existing node to form a VMware Aria Operations for Logs cluster.
VMware Aria Operations for Logs can scale out by using multiple virtual appliance instances in clusters. Clusters enable linear scaling of ingestion throughput, increase query performance, and allow high-availability ingestion. In cluster mode, VMware Aria Operations for Logs provides primary and worker nodes. Both primary and worker nodes are responsible for a subset of data. Primary nodes can query all subsets of data and aggregate the results. You might require more nodes to support site needs. You can use from three to 18 nodes in a cluster. This means that a fully functional cluster must have a minimum of three healthy nodes. Most nodes in a larger cluster must be healthy. For example, if three nodes of a six-node cluster fail, none of the nodes functions fully until the failing nodes are removed.
Prerequisites
- In the vSphere Client, note the IP address of the worker VMware Aria Operations for Logs virtual appliance.
- Verify that you have the IP address or host name of the primary VMware Aria Operations for Logs virtual appliance.
- Verify that you have a user account on the primary VMware Aria Operations for Logs virtual appliance with the Super Admin role, a role that has the relevant permissions. See Create and Modify Roles for more information.
- Verify that the versions of the VMware Aria Operations for Logs primary and worker nodes are in sync. Do not add an older version VMware Aria Operations for Logs worker to a newer version VMware Aria Operations for Logs primary node.
- You must synchronize the time on the VMware Aria Operations for Logs virtual appliance with an NTP server. For more information, see Synchronize the Time on the Log Insight Virtual Appliance.
- For information on supported browser versions, see the Release Notes.
Procedure
What to do next
- Add more worker nodes as needed. The cluster must have a minimum of three nodes.
