G’day,
Whilst analysing cluster logs in Elasticsearch, I discovered that there are approximately 10 000 log entries per minute for my 3 node cluster. That’s a lot! 99% of these are from Rancher’s canal daemonset, virtually all of which are ‘INFO’ severity.
Looking at the environment variables for the canal daemonset, I see that this is by design…
- name: FELIX_LOGSEVERITYSYS
value: info
So my questions are:
- Is it normal to see this many canal INFO messages for a 3 node cluster?
- Can I simply change the value of FELIX_LOGSEVERITYSYS to ‘warn’?
- Should ‘info’ really be the default?
Rancher: v2.0.5
Kubernetes: v10.1
