.. _monitoring-unhealthy-containers:

=========================================
Monitor for stale or unhealthy containers
=========================================

In case for bigger setups or high volume environments it can happen that workers or whole docker
containers become unresponsive or unhealthy

rcstack has a special command to restart those containers that become unhealthy to guarantee that
there are always workable containers to handle the traffic.

.. code-block:: bash

    ./rcstack stack-monitor restart-unhealthy



This will seek any containers that have a broken healthcheck status, and restart them gracefully.


It's also possible to run this command continuously in the background using

.. code-block:: bash

    nohup ./rcstack restart-unhealthy --loop=300 > unhealthy-checks.log &


This will continuously run in a loop check every 300s and check for unhealthy containers.
