Description Mike Dame 2020-04-02 19:39:01 UTC
+++ This bug was initially created as a clone of Bug #1820343 +++

Currently, setting `LogLevel` in the kube-scheduler to `TraceAll` only sets the kube-scheduler's loglevel (--v flag) to 8 (see [1]).

Since many of the scheduler's logs are at level 10 (such as scoring[2]), it would be much more helpful if the operator could configure 10 for TraceAll instead of 8

Comment 3 Mike Dame 2020-04-02 20:13:45 UTC
For QA, to verify this you should set the scheduler config (oc edit schedulers/cluster) to include the line `logLevel: TraceAll` in the spec. Then, once the kube-scheduler pods have restarted, they should have a flag `-v=10` in the kube-scheduler container
