- --storage.tsdb.path=/prometheus/data
- --storage.tsdb.no-lockfile
# Special Google flag for force deleting all data on start. We use ephemeral storage in
# this manifest, but there are cases were container restart still reuses, potentially
# bad data (corrupted, with high cardinality causing OOMs or slow startups).
# Force deleting, so container restart is consistent with pod restart.
# NOTE: Data is likely already sent GCM, plus GCM export does not use that
# data on disk (WAL).
- --gmp.storage.delete-data-on-start
# Keep 30 minutes of data. As we are backed by an emptyDir volume, this will count towards
# the containers memory usage. We could lower it further if this becomes problematic, but
# it the window for local data is quite convenient for debugging.

/*
This script deletes metric descriptors from the given projects (-projects flag),
matching the given metric type (descriptor name) regex expression (-metric_type_regex flag).
Metrics to delete will be first printed and then awaiting interactive confirmation,
before the actual removal. Dry run option also exists.
WARNING: All underlying time series behind each descriptor (potentially years
of data) will be irreversibly removed once confirmed.
Example run:
1. Setup Application Default Credentials (ADC) (https://cloud.google.com/docs/authentication/provide-credentials-adc)
if you haven't yet:
1a. Make sure the account behind the ADC for chosen projects has Monitoring Editor or Monitoring Admin permissions: https://cloud.google.com/monitoring/access-control#monitoring-perms
1b. Acquire Application Default Credentials in your environment using gcloud:
gcloud auth application-default login
2. Run Go script (from the same directory as the script):
go run delete_metric_descriptors.go -projects projects/<your-project> -metric_type_regex "<your matching expression>"
See go run delete_metric_descriptors.go -help for all options.
