@legendarier,   Please go to CM > Cloudera Management Services > Instances > Service Monitor > Charts Library > Service Monitor Storage, and check impala-query-monitoring and see how old the data is (whether it has any data or not).   See my screenshot below:   This can help to confirm if data is stored correctly or not.   In detail, CM agent will get two types of Impala queries and sends to Service Monitor, which will in term display in CM interface:   1. in flight queries CM agent will fetch in flight query IDs via API call: http(s)://{host}:{impalad-port}/inflight_query_ids CM agent will fetch in flight query details via API call: http(s)://{host}:{impalad-port}/query_profile_encoded?query_id={query_id} Above details will be combined and sent to Service Monitor service   2. finished queries CM agent will parse the query profiles under /var/log/impalad/profiles on the impala daemon host and sends data to Service monitor.   So to troubleshoot the issue, you can check:   a. CM agent log on the impala coordinator host to see if there is any impala related errors b. Service Monitor server log to see if there is any impala related errors   Hope above helps.   Cheers Eric ... View more
