Hello All,
I deleted some instances from the prometheus.yml file. But still, I am able
to see those servers' historical data. What should I do so that those
instances which I removed, those instances historical data should not have
appeared?
Example:
I am finding the unreachable servers for 30 days
*Query :*
max_over_time(up{instance=~"$instance",job="node_exporter"}[30d]) == 0
There are some servers that were unreachable for the last 30 days. Among
these servers, I deleted a few of them from prometheus.yml. But still, I am
able to see those servers in the output.
What should I do so that I didn't get these servers' details?
Thanks & regards,
Bharath Kumar.
