This Kibana plugin was born out of a project in the basement of an investment bank. Prometheus was used for all the monitoring and everything in our infrastructure stack had an exporter except Kibana. It didn't feel right leaving Kibana out of the party so this project was... hacked together, to be candid. Although it's rough around the edges, it's now used by big and small projects in all sorts of cool organizations.
The exporter's output is simple. But it would be wrong to assume that all the metrics make sense at first glance. This document aims to give a concise overview of the metrics exported by this Kibana plugin.
The first metric is the status of Kibana. Similar to the plugin metrics (see below). It can be in 1 of 3 states - Green (1), Yellow (0.5) or Red (0). However, you are unlikely to ever see a red status because it likely wouldn't respond to any requests.
kibana_status 1
The kibana_millis_uptime metric is how long the application has been running for in milliseconds.
kibana_millis_uptime 26521
The kibana_heap_* metrics represent Kibanas heap memory (bytes) usage and how much it can use.
kibana_heap_max_in_bytes 190599168
kibana_heap_used_in_bytes 150772280
The kibana_requests_* metrics represent how many requests have been made while Kibana has been online.
kibana_requests_total 0
kibana_requests_disconnects 0
The plugins statuses should show up on every kibana exporter. However, depending on your version more plugins may appear. Kibana plugins can be in 1 of 3 states which the Prometheus exporter represents numerically as 1, 0.5 or 0:
- Green (1)
- Yellow (0.5)
- Red (0)
