If I have a metric with the following labels:
my_metric{group=\"group a\"} 100
my_metric{group=\"group b\"} 100
my_metric{group=\"group c\"} 100
my_metric{gro
You can use a regex query:
my_metric{group=~"misc group.+"}
That will give you everything where group
starts with "misc group".
Yes, you can you use label replace to group all the misc together:
sum by (new_group) (
label_replace(
label_replace(my_metric, "new_group", "$1", "group", ".+"),
"new_group", "misc", "group", "misc group.+"
)
)
The inner label_replace copies all values from group into new_group, the outer overwrites those which match "misc group.+" with "misc", and we then sum by the "new_group" label. The reason for using a new label is the series would no longer be unique if we just overwrote the "group" label, and the sum wouldn't work.
It's even easier
sum by (group) (my_metric)
