Hello,
I need to lowercase the hostname of my metrics.
I would like to use the function label_replace as below. The idea here is
to create a new field called "host" that forces the lowercase of the
"hostname "field. Is it possible to use the regex (here "[[LOWER]]") to do
this ?
sum without (hostname) (label_replace(up{instance="x.x.x.x:9100"} * on
(instance) group_left(hostname) sophosav_linux_started, "host", "${1}",
"hostname", "[[LOWER]]"))
Thanks for your answer
