That's it...

If your are running the thold plugin you may need to patch it as the baseline function can't handle negative numbers under earlier versions of the plugin. If you only utilise high/low watermark checking, you do NOT need to patch.

NOTE: The patch file was made against THold v0.3.9 and may no longer apply. Use of the patch is at your descresion

cacti/plugins/thold$ patch -p0 < thold_functions-0.3.9.patch

Assumptions made within the code:

• When the script can not read the value from the SFP -40 (dBm) is returned
• snmp_port = 161
• snmp_timeout = 5000 ms
