+If the machine accessing the OhmGraphite metrics is not the same machine hosting the metrics, one may have to enable the port through the windows firewall.

+### Debugging Tips
+
+Something wrong? Try these steps
+
+- Enter the directory where OhmGraphite is installed
+- Examine `OhmGraphite.log`, do you see any lines with an "ERROR"? Fix the error.
+- If not, enable more verbose logging in `NLog.config`. Change the following line
+
+```xml
+    <logger name="*" minlevel="Info" writeTo="file" />
+```
+
+to
+
+```xml
+    <logger name="*" minlevel="Debug" writeTo="file" />
+```
+
+- Restart OhmGraphite for the logging changes to take effect
+- At the bottom of `OhmGraphite.log` `DEBUG` statements should be present informing one of all the hardware sensors detected and whenever metrics are pushed somewhere.
+- Stumped? Open an issue with relevant parts of the log included.
