Hi SuperQ, Below, the memory usage of the "node-exporter" pod deployed on a node :  below the graph with the metrics `go_goroutines` for the same node : go_goroutines{beta_kubernetes_io_arch="amd64",beta_kubernetes_io_os="linux",instance="xxxxxx",job="kubernetes-nodes-exporter",kubernetes_io_hostname="xxxxxx",.....} ...

Below the pod logs : ``` $ oc logs -f prometheus-node-exporter-krvrb time="2018-07-19T03:57:03Z" level=info msg="Starting node_exporter (version=0.16.0, branch=HEAD, revision=d42bd70f4363dced6b77d8fc311ea57b63387e4f)" source="node_exporter.go:82" time="2018-07-19T03:57:03Z" level=info msg="Build context (go=go1.10, user=root@node-exporter-binary-3-build, date=20180606-16:48:15)" source="node_exporter.go:83" time="2018-07-19T03:57:03Z" level=info msg="Enabled...

Hi Superq, I could run the command but Graphviz is not installed and I can't install it in the pod: ``` go tool pprof -svg http://localhost:9090/debug/pprof/heap > heap.svg Fetching profile...

Sorry, it's Ok :  it's Ok ? Thanks, Best regards

Hoo sorry, Please, find attachment pprof svg for node-exporter. [pprof_node_exporter.zip](https://github.com/prometheus/node_exporter/files/2213516/pprof_node_exporter.zip) Thanks Best regards

Below, the memory usage of the node-exporter since the restart of the pod: 

I took a pprof sample at 12:24:00. The node-exporter used 248MiB :  is it better to lower the MEMORY limit and take a pprof sample ? (Currently 250Mi |...

Hi, I tried to remove CPU limits without result. I'll take another pprof sample. Thanks, Best regards

Hi, I can't execute the command with `debug=2` option : ``` # go tool pprof -svg http://xxxxx:9100/debug/pprof/goroutine?debug=2 > dump_goroutine_2.svg Fetching profile over HTTP from http://xxxxx:9100/debug/pprof/goroutine?debug=2 http://xxxxx:9100/debug/pprof/goroutine?debug=2: parsing profile: unrecognized profile...

Ok, thanks for the clarification. Please, find attachment dump of the goroutines (`debug=1` & `debug=2`). [goroutine_dump.zip](https://github.com/prometheus/node_exporter/files/2219419/goroutine_dump.zip) Thanks, Best regards.
