Hi, I will schedule a cronjob as a pod in k8s cluster to generate the metrics.
The node exporter is already deployed in the k8s cluster. If I use textfile collector, is it the same with configuring in a server, that is storing the .prom in /var/log/collector, then node exporter will collect the metrics automatically?
