-### Understand the alert
-
-This alert is triggered when a `systemd slice unit` enters a `failed state`. Systemd slice units are a way to organize and manage system processes in a hierarchical manner. If you receive this alert, it means that there is an issue with a specific slice unit, which can be crucial for system stability and performance.
-
-### What does the failed state mean?
-
-A `failed state` in the context of systemd units means that the unit has encountered a problem and is not functioning properly. This could be caused by a variety of reasons, such as misconfiguration, dependency issues, or unhandled errors in the underlying service.
-
-### Troubleshoot the alert
-
-- Identify the problematic systemd slice unit.
-
- Run the following command to list all systemd units and their states:
-
- ```bash
- systemctl --all
- ```
-
- Look for the units with the `failed` state in the output, and take note of the affected unit(s).
-
-- Investigate the specific issue with the failed unit.
-
- Use the `systemctl status` command followed by the unit name to get more information about the problem:
-
- ```bash
- systemctl status <unit-name>
- ```
-
- The output will provide more details on the issue and may include error messages or log entries that can help identify the root cause.
-
-- Check the unit logs for additional clues.
-
- The `journalctl` command can be used to view the logs related to a specific unit by specifying the `-u` flag followed by the unit name:
-
- ```bash
- journalctl -u <unit-name>
- ```
-
- Analyze the log entries for any reported errors or warnings that could be related to the failure.
-
-- Address the root cause of the issue.
-
- Based on the information gathered, take the necessary steps to resolve the issue with the failed unit. This may involve reconfiguring the unit, adjusting dependencies, or fixing the underlying service.
-
-- Restart the unit and verify its status.
-
- Once the issue has been resolved, restart the systemd unit using the `systemctl restart` command:
-
- ```bash
- systemctl restart <unit-name>
- ```
-
- Afterwards, check the unit's status to confirm that it is no longer in a failed state and is functioning properly:
-
- ```bash
- systemctl status <unit-name>
- ```
