OpenReplay Administration

CLI

The CLI is helpful for managing basic aspects of your OpenReplay instance, things such as restarting or reinstalling a service, accessing a component’s logs or simply checking the status of your backend services.

Run the CLI with the -h option:

openreplay -h

And see the list of all available options:

OpenReplay backend relies on the below components/services:

Service	Description
http	Ingests events and session recordings
sink	Reads data from the streaming pipeline (Redis or Kafka for enterprise edition) and inserts into a temp storage (NFS)
storage	Moves the temp session recording files to the object storage service
assets	For caching assets (CSS, fonts and icons) to properly render the recordings
db	Reads and writes into various databases (Postgres + ClickHouse for enterprise edition)
ender	Terminates user sessions if inactive or disconnected
chalice	API for serving the frontend
alerts	Sends notifications (email, slack, in-app, webhook) when a user set threshold is reached on any of the performance metrics
integrations	Pushes and pulls data from the supported third-party APIs (Sentry, Elastic, GitHub, Jira, etc.)

Helpful Commands

Check the health status of the OpenReplay

openreplay -s

Check logs of services

openreplay -l <service name>

Increase service capacity

It’s possible to increase the capacity of any service by overriding the default cpu/memory allocation values. These latter are determined during the setup process based on your instance capacity and should fit the needs of most installations.

If you have a high volume and a big fat machine, simply run openreplay -e file and override the service’s resources. In the below example, we do it for the http worker. But this can be done for any service (i.e. sink, storage, postgresql, redis, etc.) by uncommenting and updating the below block. If you have to do it for more than one service, then simply copy and rename/update the same block (mind duplications).

http:
  resources:
    limits:
      cpu: 4096m
      memory: 8192Mi
    requests:
      cpu: 1024m
      memory: 2056Mi

Finally, reinstall the service for the new limits to take effect (your data won’t be lost):

openreplay -R

Upgrade PostgreSQL

Below are the instructions for upgrading PostgreSQL to version 1.16 or later:

Take the DB dump in the persistent volume:

If you’re using a vanilla installation, execute the following command to take a database dump:

Note: You can expect the data to get compressed to 3:1 ratio (example: if you have 15G of postgres data, it will be 5G in the dump). So make sure you have enough disk space.
```
kubectl -n db exec -it postgresql-0 -- /bin/bash -c 'PGPASSWORD=$POSTGRES_PASSWORD PGUSER=postgres pg_dumpall -v > /bitnami/postgresql/dumpall.sql'
```

Delete the existing data directory:

kubectl -n db exec -it postgresql-0 -- /bin/bash -c 'rm -rf /bitnami/postgresql/data'

Scale the PostgreSQL StatefulSet to zero to stop the current pods:
```
kubectl scale sts postgresql --replicas=0 -n db
```

Update the PostgreSQL image to version 16.3.0 or later:

kubectl set image statefulset/postgresql postgresql=bitnami/postgresql:16.3.0 -n db

Scale the StatefulSet back to one to start the updated pod:
```
kubectl scale sts postgresql --replicas=1 -n db
```
Ensure that the pod is running and the scaling operation is complete:
```
kg po -n db -l app.kubernetes.io/name=postgresql
```

Restore the database from the dump:

kubectl -n db exec -it postgresql-0 -- /bin/bash -c 'PGPASSWORD=$POSTGRES_PASSWORD PGUSER=postgres psql -f /bitnami/postgresql/dumpall.sql'

Once the upgrade is complete, you can delete the dump file from the PostgreSQL pod:

kubectl -n db exec -it postgresql-0 -- /bin/bash -c 'rm /bitnami/postgresql/dumpall.sql'

Uninstall OpenReplay

Run the below commands to uninstall OpenReplay:

sudo k3s-uninstall.sh

All the configuration stored in /var/lib/openreplay/.

sudo rm -rf /var/lib/openreplay/openreplay
