# Pushing monitoring data into Graphite

The Python scripts in this repository should help you on your way:
- elasticsearch_clusterhealth.py
- elasticsearch_indexes.py
- graylog_notifications.py
- graylog_throughput.py

###  elasticsearch_clusterhealth.py
This script grabs the health status from Elasticsearch and transforms the string value to an integer (as Graphite can't handle strings):
 - green = 0
 - yellow = 1
 - red = 2

It also transforms the boolean value of timed_out to 0 or 1

### elasticsearch_indices.py
This script grabs and rewrites index data metrics from Elasticsearch. one of the issues between elastic and Graylog is the orientation; where elastic messages are language oriented (cluster status green), Graphite can't handle anything but integers, therefor we rewrite a bunch of entries so we can make sense of it (in Grafana).

The data we push into Graphite:
 - total number of indices
 - number of green (ok) indices
 - number of yellow (impaired) indices
 - number of red (errro) indices
 - number of messages
 - deleted documents
 - total store size in bytes
 - total store size in gigabytes
 - total store size in megabytes
 - primary store size in bytes
 - primary store size in gigabytes
 - primary store size in megabytes
 - replica store size in bytes
 - replica store size in gigabytes
 - replica store size in megabytes
 - primary shards
 - replica shards

### graylog_notifications.py
A script that grabs the number of current notifications from a graylog node and pushes the integer value into Graylog.

Nothing too special

### graylog_throughput.py
Grabs the Graylog throughput (number of messages) and pushes it into Graphite so you can unleash all kinds of funky graphs, through Grafana too!
