The documentation [0]  shows how to Configure log collector CPU and memory limits.  The alignment of limits and requests should be same . In the documentation  the alignment is inconsistent.

The config  looks like below in the document:

~~~

spec:
  collection:
    type: fluentd
    resources:
      limits: 
        memory: 736Mi
        requests:
          cpu: 100m
          memory: 736Mi
~~~

The correct config should look like below: 

~~~

spec:
  collection:
    type: fluentd
    resources:
      limits: 
        memory: 736Mi
      requests:
          cpu: 100m
          memory: 736Mi
~~~
