SoS app cluster master view

[herterich]

Hi all,

we are running a splunk cluster (Version 5.0.2) with pooled searchheads. We installed the SoS app on our searchheads which will work fine. Only the "Cluster Master View" will not provide any information. Looking in the dashboards xml the reason might be, that the searches will do a rest connection to the localhost (which is the searchhead and does not provide this information). Changing the rest search from splunk_server=localhost to splunk_server= will not work, because the masternode is not defined as a search peer for the searchhead.

Any ideas how to change this. Or should we install sos app on master node which is as far as I know not srecommended.

Regards
Christian

The Cluster Master view is indeed designed to only work when consulted from the master instance. There should be no issues installing S.o.S on the cluster master, it is for the most an "inert" app and the couple of scheduled searches it runs to maintain its assets are lightweight.

Given that we are using the "rest" search command, the master would need to be a search peer of the search-head for that to work. It's possible, but not recommended and would require to modify the view.

thx, means there is no way to do a rest request from the searchhead to the master node?
