node-exporter pending status

[skyguard1]

Hello, I deployed the metrics component according to the official documentation of knative(https://knative.dev/docs/serving/installing-logging-metrics-traces/), but I found that node-exporter has been in the pending state, I have not changed the configuration, so it is not clear why this problem occurs.

os
Linux tv1-dsf-perftest-01 4.11.1-1.el7.elrepo.x86_64 #1 SMP Sun May 14 11:54:29 EDT 2017 x86_64 x86_64 x86_64 GNU/Linux
kubernetes
v1.18.2
knative
v0.15.0

Hope to get your answer, thank you.

I noticed the warning nodes did not have free ports for the requested pod ports which seems like a k8s issue, not Knative one.

Could you please print out the result of kubectl describe pod <node-exporter-pod> and see if there is any detailed information about port collision?
