pgslot-notify-bot is a tool designed to monitor PostgreSQL replication slots. It provides notifications if a replication slot grows beyond a specified size. This is particularly useful for database administrators and teams who need to keep an eye on replication slot sizes to prevent issues related to disk space and replication lag.
Before setting up pgslot-notify-bot, ensure you have:
- A PostgreSQL database
- A Slack workspace for notifications
-
Clone the repository:
git clone [email protected]:PeerDB-io/pgslot-notify-bot.git cd pgslot-notify-bot
-
Set up the environment:
-
Copy the
.env.templatefile to a new file named.env.cp .env.template .env
-
Fill in the values in the
.envfile with your specific settings.
-
-
Running the bot:
-
Use the provided script to start the bot.
./run.sh
-
You need to set the following environment variables in the .env file:
DEPLOYMENT_NAME: The name of the postgres deployment to monitor.SLACK_BOT_TOKEN: Your Slack bot token.SLACK_CHANNEL: The Slack channel where notifications will be sent.DB_HOST: The host of the PostgreSQL database.DB_PORT: The port of the PostgreSQL database.DB_USER: The user for the PostgreSQL database.DB_PASSWORD: The password for the PostgreSQL database.DB_NAME: The name of the PostgreSQL database.INTERVAL_SECONDS: The interval in seconds for the bot to check the replication slot size.SIZE_THRESHOLD_MB: The size threshold in MB for the replication slot. Notifications are sent if this size is exceeded.
Once the bot is running, it will automatically check the size of the PostgreSQL replication slots at the defined interval. If a replication slot size exceeds the specified threshold, a notification will be sent to the configured Slack channel.
