What this PR does / why we need it:

#2701 (comment)

Context:

  • we only have a list of endpoints to remove from the metrics
  • we need all the label to delete a metric

Process:

  • after a reload and before replacing the running model, create a list of endpoints not available anymore
  • request to /metrics to get current metrics
  • for each endpoint to remove, get the metric/s
  • for each metric obtained in the previous step delete prometheus metric

@brancz I am trying to implement the cleanup but I am not sure the information I get at this point (the IP addresses I need to remove from the metrics) is enough. Any advice?

I believe you are actually going to have to go through all label values and combinations, not just upstream_ip.

Basically you need to pass to Delete all the labels that you passed into metric.WIthLabelValues, so yes all labels of that metric.

Scenario:

  • one ingress rule
  • one deployment with five endpoints

Current metrics:

If an endpoint is removed, for instance 172.17.0.4:8080

$ kubectl exec -it -n ingress-nginx nginx-ingress-controller-677b75cbf-pnbdb curl localhost:10254/metrics|grep 'upstream_ip="172.17.0.4:8080"' | sed -n 's/.*{\(.*\)}.*/\1/p' | sed -n 's/\(.*\)\,le.*/\1/p' | uniq
host="echoheaders",ingress="http-svc",method="GET",namespace="default",path="/",protocol="HTTP/1.1",service="http-svc",status="200",upstream_ip="172.17.0.4:8080",upstream_name="default-http-svc-80",upstream_status="200"

this extracts a list of metrics with all the labels that should be removed.

@brancz please tell me I don't need to use a hack like this one to remove metrics.

Doing a request against /metrics and then parsing with a shell script seems rather sketchy. How about we add some tracking logic to record which label combinations have been used to set metrics for a respective upstream and then iterate over of those when the upstream is removed and delete all metrics with the label combinations. I'm thinking two nested sync.Maps, the first to index upstream, and the second to build a set of label combinations to iterate over on deletion.

I have the same feeling about this but it's really simple and does not require storing anything in the controller.

I'm thinking two nested sync.Maps, the first to index upstream, and the second to build a set of label combinations to iterate over on deletion.

Basically store the metrics twice, just to be able to delete both metrics?
I thought of doing something similar but it would consume too much memory.

Agreeing with @brancz, this really seems brittle.

I think the best option is to use NewConstMetric and manage the values 'manually'. Alternatively I think you can call registry.Gather() to get the current set of metrics.
