Hi Esix, Thanks for update. I have reverted back the Disabled settings per suggestions, am able to run all perl scripts on linux shell successfully, However, still not able to view metric data on "Splunk App for Cassandra". Also have received following messages as well. "Search peer xxxx.prod.com has the following message: Received event for unconfigured/disabled/deleted index=cassandara_process with source="source::source_stats_process" host="host::xxxxx" sourcetype="sourcetype::cassandra_PROCESS". So far received events from 6 missing index(es)" Previously we had following configuration: 1 index per cluster. 1 source "system.log" 1 sourcetype systemlog Now after configuring "add-on for cassandra", i can see search data for the other source types (cassandra_PROCESS, cassandra_MEM, etc.), plus, if i search from "Search and Reporting App", i can fetch data from other source types, but "App for Cassandra" is unable to show data/graphs and i can see "No Results Found". Thanks, ... View more
