Is it possible to access elasticsearch's internal stats via Kibana

I can see from querying our elasticsearch nodes that they contains internal statistics that for example show disk, memory and CPU usage (for example via GET _nodes/stats API).

Is there anyway to access these in Kibana-4?

Solution

  • Not directly, as ElasticSearch doesn't natively push it's internal statistics to an index. However you could easily set something like this up on a *nix box:

    1. Poll your ElasticSearch box via REST periodically (say, once a minute). The /_status or /_cluster/health end points probably contain what you're after.
    2. Pipe these to a log file in a simple CSV format along with a time stamp.
    3. Point logstash to these log files and forward the output to your ElasticSearch box.
    4. Graph your data.
