Hi,
i'm using node_exporter to export stats for all my nodes. I have two
nodes however that have no network connection, but I still want to
monitor them.(all ports closed, except for ssh and nfs from one other
machine, and I cannot change this.
They do however have a mounted nfs fileshare.
What would be a good solution to export the node info to a prometheus
server since I cannot scrape those nodes and pushgateway is also not
possible.
is there a way to save the node_exporter info as file and push it to
prometheus from the other machine that also has access to the file share?
While not ideal you could try creating a cron job that runs every
minutes that does a local curl to the node exporter (which is just
listening on localhost/loopback) and saves the resulting metrics in a
file on your NFS share. Another server which does have both NFS &
network access could then use the textfile collector to pick up those
metrics. You would need to do something to munge the metrics before they
are written to the NFS share as otherwise the metrics would conflict
with the ones being created normally by the node exporter that is
running the textfile collector.
