+### Getting Logs
+
+If you're encountering problems with the `[[ entry.meta.module_name ]]` collector, follow these steps to retrieve logs and identify potential issues:
+
+- **Run the command** specific to your system (systemd, non-systemd, or Docker container).
+- **Examine the output** for any warnings or error messages that might indicate issues.  These messages should provide clues about the root cause of the problem.
+
+#### System with systemd
+
+Use the following command to view logs generated since the last Netdata service restart:
+
+```bash
+journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep [[ entry.meta.module_name ]]
+```
+
+#### System without systemd
+
+Locate the collector log file, typically at `/var/log/netdata/collector.log`, and use `grep` to filter for collector's name:
+
+```bash
+grep [[ entry.meta.module_name ]] /var/log/netdata/collector.log
+```
+
+**Note**: This method shows logs from all restarts. Focus on the **latest entries** for troubleshooting current issues.
+
+#### Docker Container
+
+If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:
+
+```bash
+docker logs netdata 2>&1 | grep [[ entry.meta.module_name ]]
+```
