After edit the configmap's log_level to error and set FELIX_LOGSEVERITYSYS pod environment variable as error, I can still see lots of INFO level logs when attach the canal pod

Expected Behavior

Only error level logs are output

Current Behavior

Can not find a way to change the log level

Steps to Reproduce (for bugs)

  1. edit the configmap, set log_level as error
  2. edit the daemonset, set the FELIX_LOGSEVERITYSYS as error
  3. kubectl attach calico-pod -n kube-system -c calico-node

Context

Did I miss anything or this is not the right way to config the log level?

Your Environment

  • Calico version: v3.1.3
  • Flannel version: v0.9.1
  • kubernetes version: v1.11.0
  • Operating System and version: ubuntu16.04

I think that is the wrong env var to set in the daemonset. I think you should use FELIX_LOGSEVERITYSCREEN, that one you edited is for sending logs to syslog. I think that manifest needs to be fixed, I just checked and if you look at https://docs.projectcalico.org/v3.1/getting-started/kubernetes/installation/hosted/calico.yaml you'll see it uses the env var I suggested.

I've put up projectcalico/calico#2116 to fix the docs(manifests).

@tmjd FELIX_LOGSEVERITYSCREEN works. Thank you very much for your help.
