Could it used to monitor elasticsearch cluster health like watcher?

[halfcrazy]

Currently i found the rules are based on the index, but there is no built-in index for elasticsearch but some api.

The elastic official monitor tool has this feature.

It would be nice to have the option to trigger an alert if a cluster health is not green.
