Hi,

That link contains the settings provided by Cloudera Manager to monitor impala services, I do not think that's what you are looking for. They are specific to Cloudera Manager, not part of Impala.

Cloudera Manager internally queries this page provided by Impala daemon host:

http://<impala-daemon-url>:25000/inflight_query_ids

to determine if the impala is responding to requests. This page will return a list of query IDs that is inflight. How long it takes to get a response and how many queries are running at a time, could give you some indication of the health of the impala daemon.

Hope this helps.
