Hello,
From Hawkular team we are working to create a lightweight alerting component that can alert on Elasticsearch and combined with other ecosystems like Prometheus and Apache Kafka.
We would like to get feedback about these features and how we can improve them to be useful into the Elasticsearch community.
The aim is to complement a gap where today an integration between systems is mandatory.
We have prepared a couple of blog post about this feature

And a demo
Please, let us know what do you think and if this could be interesting for your projects.
Thanks !
Lucas Ponce
