I'm with a team that is migrating our monitoring stack to open source. I've implemented some fantastic performance and service-specific monitoring using the ELK stack.
One key monitor I need to implement which isn't exactly straightforward is simple node Up/Down monitoring. I've got this working down to a service-specific level by using Nmap to write to a file which I tail with Filebeat
(e.g. `nmap mapsmysql01 | grep mysql >> /var/log/alerts/mysqlup.log`)
However, I must intermittently check that both mysql is down and filebeat is up before throwing an alert.
Is there a more elegant way to monitor service or node up/down? I imagine I'm missing something here..

[Heartbeat](https://github.com/elastic/beats/tree/master/heartbeat) ([snapshots](https://beats-nightlies.s3.amazonaws.com/index.html?prefix=heartbeat/) ) might be of interest to you. It's a new Beat we are working on to monitor availability.
It doesn't have docs yet and it's not released. Have a look at the config file and readme.

Thanks @andrewkroh, that looks like precisely what I was hoping for.
