Kubernetes nodes scrape problems

[felixPG]

Hi:

After working with a kubernetes cluster since 3 months with prometheus without problems, today scrape does not work in one node (master kubernetes node), is work for little metrics, an other metrics does not work.

Example:

For kube_node_labels metric the node appear to be scraped:

But for node_uname_info, node_boot_time, node_time cant see the IP of the node, in this case, should be 192.168.133.17 for ietsmartc09spre

I dont know what happend with this, all was working ok until today!
Thanks in advance!

It makes more sense to ask questions like this on the prometheus-users mailing list rather than in a GitHub issue. On the mailing list, more people are available to potentially respond to your question, and the whole community can benefit from the answers provided.

I reply to myself, the issue was because I forget to taint the kubernetes master and the node-exporter pod was unable to run on a master node without taint!
