Monitoring Alation

Customer Managed Applies to customer-managed instances of Alation

Alation provides several ways for Server Admins to monitor the status and health of the application. You’ll be able to:

  • Find out whether components are functioning correctly

  • Detect configuration or connectivity issues

  • View application logs to help diagnose issues

Monitoring the Alation Server with Alerts

Starting with 2021.4.5, Alation will automatically alert Server Admins if any of the root or data volumes are filled over a certain threshold. You can adjust the threshold for the default alert, along with how often the check is performed. You can also configure your Alation instance to run additional server health checks.

See Default Server Health Alerts and Configuring Server Health Alerts for Administrators for more details.

Monitoring Component Health

The Alation application includes several individual components. Each component must be working correctly for Alation to function. You can see the status of each component in a few different ways.

Monitoring the Health Checks Page

The easiest way to monitor the health of each component is the Health Checks page in Alation. You can find this page in the Monitor section of the Admin Settings. You can enable the Health Checks page using the command line on your Alation server.

See the Monitor Component Health topic for details.

Monitoring the i_am_alive URL

You can see the current status of each component by visiting <your-alation-instance-URL>/monitor/i_am_alive/. You must type this URL manually into the address bar of your browser. Here’s an example of what you’ll see:

{"django": "ok", "postgres": "ok", "elastic_search": "ok", "redis": "ok", "task_server": "ok", "connector": "ok", "celery": "ok", "kvstore": "ok"}


In versions before 2022.1, Alation component health could be monitored at the /manager/healthcheck/ URL. This page was deprecated in version 2022.1. From 2022.1, use /monitor/i_am_alive/ to view the component status. Note that both these URLs contained the same information except the status of Nginx and uWSGI, which are not available at the current /monitor/i_am_alive/ URL.

Monitoring with Actions on the Alation Server

You can check the status of individual components via the command line on the Alation server. Go to Alation Actions and look for the word “status” for details.

Monitoring Background Tasks

Alation provides the ability for Server Admins to monitor background tasks directly in the Alation UI. See Monitor Tasks for more information.

Monitoring Postgres Table Size

Alation can monitor the size of the internal Postgres tables relative to the available disk space. See Managing Space: Monitoring Postgres Table Size for more information.

Checking the Replication Status

If you have a High Availability (HA) setup of Alation, you can view the status of replication between the Primary and Secondary nodes by visiting:


See Checking Replication Status for more detail.

If you haven’t set up High Availability, the /monitor/replication page will show that you’re in standalone mode.

{"replication_mode": "standalone"}

Getting the Server Hostname

If your Alation instance is behind a virtual IP, you can get the physical hostname by visiting:


Example output:

{"hostname": "ip-10-11-2-184", "site_id": "ALATION_INTERNAL_0", "base_url": "", "mode": "standalone"}

Finding and Viewing Logs

Each component of the Alation application writes the details of its operation, warnings, and errors into a dedicated log file. If users experience an issue with Alation, logs may have information about it.

See Logs Overview for more information about the location and purpose of each log file.

Alation provides a way to bundle and encrypt the application logs. See Logging Tab: Sending Encrypted Logs for more information.
