Create an Explore cluster
For the best performance, data redundancy, and stability, you must configure at least three Explore appliances
in an Explore cluster.
Before you begin
You must have already installed the Explore appliances in your environment before proceeding.
In the following example, the Explore appliances have the following IP addresses:
•
Node 1: 10.20.227.177
•
Node 2: 10.20.227.178
•
Node 3: 10.20.227.179
You will join nodes 2 and 3 to node 1 to create the Explore cluster.
Important:
Each node that you join must have the same configuration (physical or virtual) and the
same ExtraHop firmware version. EXA 5100 and EXA 5200 physical appliances can be in
the same cluster.
1. Log into the Admin UI on all three Explore appliances with the setup user account in three separate
browser windows or tabs.
2. Select the browser window of node 1.
3. In the Status and Diagnostics section, click
Fingerprint
and note the fingerprint value. You will later
confirm that the fingerprint for node 1 matches when you join the remaining two nodes.
4. Select the browser window of node 2.
5. In the Explore Cluster Settings section, click
Join Cluster
.
6. In the Host field, type the hostname or IP address of node 1 and then click
Continue
.
Note:
For cloud-based deployments, be sure to type the IP address listed in the Interfaces table
on the Connectivity page.
7. Confirm that the fingerprint on this page matches the fingerprint you noted in step 3.
