We monitor hundreds of switch ports and I want to set the sensor in PRTG to "Show Alarm when Disconnected" for all the switch ports. The problem is PRTG is showing alarms on ports that are Administratively down in the switch. Other monitoring software I've used would ignore these ports and only alert if the ports were enabled. Is there a way to do this with PRTG? Then we wouldn't have to go and modify the sensor every time we enable or disable a port. Thanks in advance
Can PRTG ignore ports that are administratively down?

Hello,
thank you very much for your KB-Post. As we've had a few requests on this, an improvement will be implemented shortly into the canary branch. It will then be possible to have the sensor ignore "deactivated" interfaces. I can'T say exactly when this will reach the stable branch, current plans aim for version 14.x.11, so with the third version number being an 11 it should be available in the stable channel.
best regards,

Hello,
I'm afraid while it's not possible to only create sensors with a certain Oper-state, you can at least define which states mean an alert, with a custom device template as follows:
<?xml version="1.0" encoding="UTF-8"?> <devicetemplate id="custom" name="Custom SNMP Traffic" priority="1"> <check id="ping" meta="ping"/> <create id="pingsensor" kind="ping" requires="ping" displayname="PING"> <createdata> <priority>5</priority> <timeout>2</timeout> <interval>30</interval> </createdata> </create> <check id="snmp" meta="snmp" requires="ping"/> <create id="snmptraffic" kind="snmptraffic" requires="snmp" meta="portscan"> <createdata> <trafficmode/> <monitorstate>2</monitorstate> </createdata> </create> </devicetemplate>
SNMP Traffic Sensors created with this template will only alert when Show alarm when disconnected, but ignore when deactivated happens.
Save the above into a file for example called *Custom SNMP Traffic* and save it into the
\devicetemplates\
subfolder of your PRTG Program Files folder. You can then use it with the Auto-Discovery.
