how to get customize metrics with node exporter from a container

[nina guo]

Hi,

I'm running a cronjob as a container inside k8s cluster, at the same time a node exporter has been deployed on this node.

--collector.textfile.directory=/var/log/texfilecollector also has been defined from node export side. And the customize metrics are stored in defined directory /var/log/texfilecollector.

But now I failed to obtain the customized metrics with Prometheus UI.

Could some experts provide kind help?

Hi Nina,

Did you confirm that:

* Prometheus is scraping the Node Exporter

* When you manually go to the /metrics endpoint of the Node Exporter, it contains your custom metrics?

* The Node Exporter doesn't log any errors about the textfile collector failing? In that failure case, it should also expose a metric "node_textfile_scrape_error" with a value of 1.
