I want to send an alert while I inserting a document with a value more than I configured. Suppose if I configured the KPI as \>75 and it crosses it I need a alert.
Sample doc
`{ "user" : "Kimanchi", "KPI" : 60 }`
Suppose if i inserted the below doc I need an email alert
`{ "user" : "Kimanchi", "KPI" : 72 }`
For this i saw `elastalert. Is there any pre-build functions are there in elastic-search for these type of requirements???

The [Watcher Plugin](https://www.elastic.co/products/watcher) can do this for you, but do note that it's a commercial plugin. Or you could setup some [Percolators](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-percolate.html) which your application monitors and alerts on
Elasticsearch itself does not have any to actually push out alerts via email, pager-duty, etc. You'll need to either use Watcher or code that yourself in your application.

Can you please show any example on how to use percolators in this scenario???
How reabile this `elasalert`?? [http://elastalert.readthedocs.io/en/latest/elastalert.html](http://elastalert.readthedocs.io/en/latest/elastalert.html)
