This plugin collects Elasticsearch cluster and nodes statistics using Snap telemetry framework.
The intention for this plugin is to collect metrics for Elasticsearch nodes and cluster health.
This plugin is used in the [Snap framework] (http://github.com/intelsdi-x/snap).
In order to use this plugin you need the Elasticsearch cluster that you can collect metrics from.

- Elasticsearch node/cluster
- golang 1.6+
All OSs currently supported by Snap:
- Linux/amd64
- Darwin/amd64
To install sysstat package from the official repositories simply use:
- For Darwin/amd64:
brew install elasticsearch - For Docker installation:
$ docker pull elasticsearch

- Set up the Snap framework
- Ensure Snap global configuration is defined
To learn more about this plugin:
This plugin can gather Elasticsearch node and cluster level statistics. The node level statistics are similar for each node except that each node has a different node id. To show the statistics for all nodes inside a cluster, using a wildcard * to represent node id in the task manifest. Otherwise, a particular node id may be specified.
In the node level, this plugin collects metrics listed the next catalog.
| Metric Name | Description |
|---|---|
| indices | Indices stats about size, document count, indexing and deletion times, search times, field cache size, merges and flushes |
| os | Operating system stats, load average, mem, swap |
| process | Process statistics, memory consumption, cpu usage, open file descriptors |
| jvm | JVM stats, memory pool information, garbage collection, buffer pools, number of loaded/unloaded classes |
| thread_pool | Statistics about each thread pool, including current size, queue and rejected tasks |
| fs | File system information, data path, free disk space, read/write stats |
| http | HTTP connection information |
| breaks | Statistics about the field data circuit breaker |
| script | Computing the grades stats based on a script |
Example running snap-plugin-collector-elasticsearch and writing data to a file.
In one terminal window, open the snap daemon (in this case with logging set to 1 and trust disabled):
$ snapteld -l 1 -t 0
In another terminal window:
