Hi,
I have a query with promql. I have prom sd configuration to scrape
metrics from my kube cluster. I want to know if it is possible to cut
string and apply it as label name.
My project has test01, test02 and preprod environments but namespaces
will be test01-internal, test02-internal, prodref-internal and
prodref-external .Because of prometheus sd config the env is coming as
test01-internal where i want only test01. Is it possible to extract
only this string and using replace i can send this as env label.
Yes you can do that with relabeling.
Use a regular expression match, with a () around the bit you want to
keep. That will then be stored in $1, which is the default already for
the "replacement:" field.
