+### 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>
+ ```
