va-live-crawler causes high CPU and memory

Live-crawlers in each node of your IBM® Cloud Private clusters can cause high CPU and memory occupancy.

Resolving the problem

You can add CPU and memory resource limits to work around the problem.

1. Find the following two deamonsets.

   vulnerability-advisor-process-ma-crawler
   vulnerability-advisor-live-crawler
   

2. Edit the daemonsets to add resource limits.

   kubectl edit ds vulnerability-advisor-live-crawler -n kube-system
   kubectl edit ds vulnerability-advisor-process-ma-crawler -n kube-system
   

3. Add your CPU and memory limits.

   resources:
           limits:
             cpu: 100m
             memory: 128Mi
           requests:
             cpu: 50m
             memory: 64Mi
