Etcd by HTTP
Overview
For Zabbix version: 6.2 and higher
The template to monitor Etcd by Zabbix that work without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
Template Etcd
— collects metrics by HTTP agent from /metrics endpoint.
See https://etcd.io/docs/v3.4.0/op-guide/monitoring/#metrics-endpoint.
This template was tested on:
- Etcd, version 3.0+
Setup
See Zabbix template operation for basic instructions.
- Import template into Zabbix
- After importing template make sure that etcd allows for metric collection.
Test by running:
curl -L http://localhost:2379/metrics
- Check if etcd is accessible from Zabbix proxy or Zabbix server depending on where you are planning to do the monitoring.
To verify run
curl -L http://<etcd_node_address>:2379/metrics
-
Add the template to each node with etcd. By default template use client port. You can configure metrics endpoint location by --listen-metrics-urls flag (See etcd docs).
If you have specified a non-standard port for etcd, don't forget change macros {$ETCD.SCHEME}, {$ETCD.PORT}.
If you need it, you can set {$ETCD.USERNAME} and {$ETCD.PASSWORD} macros in the template for using on the host level.
Test availability:
zabbix_get -s etcd-host -k etcd.health
Besides, see the macros section as it will set the trigger values.
Zabbix configuration
No specific Zabbix configuration is required.
