I am pretty new to Elasticsearch and currently working on the alerting mechanism provided by kibana.
I am struggling to configure an alert for my Instance usage like Disk size, Usage, JVM heap, etc.
I am not sure what input should I use to fetch the above mentioned details in the alerting UI section.
all the monitoring data is stored in an index, so you need to use a search input with the query you want to execute.
I highly recommend to check out an introductory post how to write/debug watches and also to check out our examples repo to get a first feel on how all of this works.
