Connect the Discover and Command appliances to Explore appliances

After you deploy an Explore appliance, you must establish a connection from all ExtraHop Discover and Command appliances to the Explore appliance before you can query for stored records.

Important:If you have an Explore cluster of three or more Explore nodes, connect the Discover appliance to each Explore node so that the Discover appliance can distribute the workload across the entire Explore cluster.
Note:If the Explore appliance connections are managed from a Command appliance, you must perform this procedure from the Command appliance instead of from each Discover appliance.
  1. Log into the Admin UI on the Discover or Command appliance.
  2. In the ExtraHop Explore Settings section, click Connect Explore Appliances.
  3. Click Add New.
  4. In the Explore node field, type the hostname or IP address of any Explore appliance in the Explore cluster.
  5. For each additional Explore appliance in the cluster, click Add New and enter the individual hostname or IP address in the corresponding Explore node field.


  6. Click Save.
  7. Confirm that the fingerprint on this page matches the fingerprint of Node 1 of the Explore cluster.
  8. In the Explore Setup Password field, type the password for the Explore Node 1 setup user account and then click Connect.
  9. When the Explore cluster settings are saved, click Done.

Next steps

Important:If you only deployed a single Explore appliance, after you connect to your Discover or Command appliance, you must log into the Admin UI on the Explore appliance and set the Explore Cluster Settings > Data Management > Replication Level to 0.

Disconnect the Explore appliances

To halt the ingest of records to the Explore appliance, disconnect all Explore appliances from the Command and Discover appliances.

Note:If appliance connections are managed by a Command appliance, you can only perform this procedure on the Command appliance.
  1. Log into the Admin UI on the Discover or Command appliance.
  2. In the ExtraHop Explore Settings section, click Connect Explore Appliances.
  3. Click the red X next to every node in the Explore cluster.


  4. Click Save.
