# PG Slot Notify: Monitor Postgres Slot Growth in Slack

We're excited to launch [pgslot-notify-bot](https://github.com/PeerDB-io/pgslot-notify-bot), our latest open-source tool designed to surface the well-known issue of replication slot growth in PostgreSQL, as highlighted in [this earlier article](https://blog.peerdb.io/five-tips-on-postgres-logical-decoding). This tool is useful for database administrators to preemptively tackle problems associated with replication slot size increases, ensuring smooth database operations.

## **Features**

* **Monitoring**: Checks the size of PostgreSQL replication slots at specified intervals.
    
* **Slack Alerts**: Instant notifications to a designated Slack channel for quick action. Tags `@channel` for slots that exceed the threshold otherwise just posts a message.
    
* **Easy Setup**: Simple configuration with an `.env` file, allowing quick deployment. There is also a `docker-compose.yaml` for those who prefer that.
    
* **Adjustable Thresholds**: Users can set size limits to suit their database needs.

## **Future**

We see this bot to evolve to monitor other common issues that arise when replicating data in PostgreSQL, be it number of open connections or contentions by looking at `wait_event` and`wait_event_types`.
