Hi,
I am new to this forum, and have a question. I am using Prometheus Node Exporter for monitoring inodes in filsets.
I have different metrics for filesets and those look very similar. Here an example of what I like to accomplish:
gpfs_fileset_alloc_inodes{fileset="da-kligen01",fs="prd01"} 1.8612224e+07
gpfs_fileset_free_inodes{fileset="da-kligen01",fs="prd01"} 3.756478e+06
gpfs_fileset_max_inodes{fileset="da-kligen01",fs="prd01"} 1.43285248e+08
As you can see these are all almost the same, and I would like to have these all in one LLD discovery rule. My idea was that I
could do this by using a Prometheus to JSON preprocessing step looking like this: {__name__=~"gpfs_fileset_.*_inodes"}{fileset=~".*" ,fs=~".*"}
In this way I could also use an Item prototype to calculate the percentage used. But the regular expression returns an error: Incorrect value for field "params": invalid Prometheus pattern.
What am I doing wrong. As far as I read the documentation, this should work... What am I overlooking?
Using this same prepocessing without regular expressions for the metric works fine.
Hope someone can help out here.
Frans.
