Some of the commands that have been asked to run are below, it would be nice to have all of this in the support package if needed.
cat /sys/fs/cgroup/memory.stat from within a Ingress Controller pod
for p in $(pidof nginx nginx-ingress); do sudo pmap ${p} -X; done from the k8s node running the Ingress Controller pods
for p in $(pidof nginx nginx-ingress); do cat /proc/${p}/status; done since azure was unable to run the command above
Collect the following information from the API endpoint from the pods:

/api/8/processes
/api/8/connections
/api/8/slabs
/api/8/http/requests
/api/8/http/server_zones
/api/8/http/location_zones
/api/8/http/caches
/api/8/http/upstreams
/api/8/http/keyvals

Our plan is to deploy a custom container as a sidecar in the pod to fetch the necessary data.
