Cleanup Storage

Each recording exists in the form of a file and an entry in the database. OpenReplay dumps what’s necessary to replay a session (DOM mutations, mouse coordinates, console logs, network activity and much more) into a single file. These files are by default stored on your instance, so they make up most of its storage.

Session metadata will be stored in the PostgreSQL database forever, but after 180 days the file containing the recording will be expired/deleted through a minio lifecycle policy.

Change default lifecycle policy

Section titled Change default lifecycle policy

You can change the default lifecycle policy this way:

  1. Run k9s -n db
  2. Use the keyboard arrows to navigate the list and get to the minio-* container
  3. Press s to have shell access the Minio (object storage) container
  4. Run mc alias set minio http://localhost:9000 $MINIO_ACCESS_KEY $MINIO_SECRET_KEY
  5. Run mc ilm set --id mobs --expiry-days 14 minio/mobs (i.e. automatically clean recordings 14 days after creation)
  6. Use exit to exit the Minio container
  7. Run :quit to exit the Kubernetes CLI

Use the below SQL query if you wish to cleanup data from your database (PostgreSQL). Replace the epoch timestamp (milliseconds) with the date from which to keep recordings. It’s a cascade delete, so all recordings as well as their corresponding events will be removed from the database.

Important: This is done at your own risk, so be extremely careful when performing such actions in the database.

--- Cascade delete all sessions and their related events captured before Jan 1st, 2021
DELETE FROM public.sessions WHERE start_ts < extract(epoch from '2021-01-01'::date) * 1000;

Login to your OpenReplay instance, then:

  1. Run k9s -n db
  2. Use the keyboard arrows to navigate the list and get to the postgresql-* container
  3. Press s to have shell access the the Postgres container
  4. Run PGPASSWORD=MY_PG_PASSWORD psql -U postgres (replace MY_PG_PASSWORD with the value of the postgresqlPassword variable from /openreplay/scripts/helmcharts/vars.yaml file)
  5. Execute your delete (or any other) query
  6. Type exit to exit the postgresql-client
  7. Use exit to exit the Postgres container
  8. Run :quit to exit the Kubernetes CLI

If you ever need to free up some space, then login to your OpenReplay instance and follow the below steps:

  1. Run k9s -n db
  2. Use the keyboard arrows to navigate the list and get to the minio-* container
  3. Press s to have shell access the Minio (object storage) container
  4. Run mc alias set minio http://localhost:9000 $MINIO_ACCESS_KEY $MINIO_SECRET_KEY
  5. Run mc rm --recursive --dangerous --force --older-than 7d minio/mobs (i.e. delete files that are older than 7 days)
  6. Use exit to exit the Minio container
  7. Run :quit to exit the Kubernetes CLI
