How to update your etcd space alerts for better etcd monitoring
This document (000020187) is provided subject to the disclaimer at the end of this document.
An alert you may have seen is
Database usage close to the quota 500M in your Rancher 2.x cluster.
This is a default etcd alert built into Rancher, you can find more info on the default alerts here: Rancher v2.x Default Alerts
Upon further examination of the alert, you see the description of
A warning alert is triggered when the size of etcd exceeds 500M.
This alert is somewhat misleading as the default etcd size is 2GB. This alert is also at a severity level of Warning. Below, we suggest configuring your etcd alerts to better utilize the alert thresholds and to avoid the default alert constantly going off.
- Running Rancher v2.x
You can access the alerts by going to
Tools -> Alerts at the cluster level. From here, clone the default alert three times. Once the 3 clones are created, disable the default alert so you always retain a clean reference alert.
If you are running out of space, please reference the following two links. There will be an upcoming KB article walking through the resize process for etcd.
