Apart from the generic health dashboards for monitoring the health of the elasticsearch, is there anyway to measure the following metrics through API calls ?
- The number of active users in the elasticsearch cluster at a given time.
- Finding out the disk space occupied by the indices(new data) in a given day.
- Counting the number of triggered alerts.
I explored the X-pack APIs and relevant sections of the documentation, but couldn't find out what I am looking for. Could you kindly provide your valuable suggestions/opinions ?
PS: I am a ELK stack neophyte and badly need your(community) help.
