+### Understand the alert
+
+This alert indicates that the Pi-hole blocklist (Gravity) file hasn't been updated for an extended period of time. The blocklist file contains domains that have been processed by Pi-hole to filter ads and malicious content. An outdated blocklist may leave your system more vulnerable to unwanted content and threats.
+
+### Troubleshoot the alert
+
+1. **Check the current blocklist update status**
+
+   To see how long it has been since the last update, you can use the following command:
+
+   ```
+   root@netdata~ # pihole -q -adlist
+   ```
+
+   This will display the timestamp of the last update.
+
+2. **Rebuild the blocklist**
+
+   If the alert indicates that your blocklist file is outdated, it's essential to update it by running:
+
+   ```
+   root@netdata~ # pihole -g
+   ```
+
+   This command will download the necessary files and rebuild the blocklist.
+
+3. **Check for errors during the update**
+
+   If you encounter any issues during the update, check the `/var/log/pihole.log` file for errors. You can also check the `/var/log/pihole-FTL.log` file for more detailed information on the update process.
+
+4. **Verify the blocklist update interval**
+
+   To ensure that your blocklist file is updated regularly, make sure you configure a regular update interval. You can do this by editing the `cron` job for Pi-hole:
+
+   ```
+   root@netdata~ # crontab -e
+   ```
+
+   This will open an editor. Look for the line containing the `pihole -g` command and adjust the schedule accordingly. For example, to update the blocklist daily, add the following line:
+
+   ```
+   0 0 * * * /usr/local/bin/pihole -g
+   ```
+
+   Save the file and exit the editor to apply the changes.
+
+5. **Monitor the blocklist update status**
+
+   After performing the necessary troubleshooting steps, keep an eye on the `pihole_blocklist_last_update` alert to ensure that your blocklist file is updated as expected.

+### Understand the alert
+
+This alert monitors if Pi-hole's ability of blocking unwanted domains is active. If you receive this alert, it means that your Pi-hole's ad filtering is currently disabled.
+
+### Troubleshoot the alert
+
+1. Check the status of Pi-hole
+
+To check the current status of Pi-hole, run the following command:
+```
+pihole status
+```
+This command will show if Pi-hole is active or disabled.
+
+2. Re-enable Pi-hole
+
+If Pi-hole is disabled as per the status, you can re-enable it by running the following command:
+
+```
+pihole enable
+```
+
+3. Confirm Pi-hole is enabled
+
+After running the previous command, run `pihole status` again to confirm that Pi-hole is now enabled and blocking unwanted domains.
+
+4. Check for errors or warnings
+
+If Pi-hole is still not enabled, take a look at the logs for any errors or warnings:
+
+```
+cat /var/log/pihole.log | grep -i error
+cat /var/log/pihole.log | grep -i warning
+```
+
+5. Rebuild the blocklist
+
+If you still face issues, you can try rebuilding the blocklist by running:
+
+```
+pihole -g
+```
+
+6. Update Pi-hole
+
+If the problem persists, consider updating Pi-hole to the latest version:
+
+```
+pihole -up
+```
