When using the PRTG web interface, I would like to view a list of sensors that carry several tags. For example, I want to show sensors only that have both a myTag and and bandwidthsensor tag.
Also, is it possible to only show sensors of a certain type that carry a certain tag?

Filter Sensor Lists by Several Tags
In the PRTG web interface, when you choose Sensors | By Tag | ... from the main menu, PRTG calls a URL which shows a sensor list filtered by the selected tag. For example,
/sensors.htm?filter_tags=@tag(bandwidthsensor)
shows a list of all sensors which are tagged bandwidthsensor.
Using this mechanism, you can add additional tags to this filter in order to extend the list. For example,
/sensors.htm?filter_tags=@tag(bandwidthsensor,snmptrafficsensor)
will show a combined list containing all sensors tagged bandwidthsensor or snmptrafficsensor.
In order to make tags obligatory (similar to a Boolean AND operator), add a + sign in front of each tag. Note: The + sign has to be URL-encoded! So, use %2b instead. For example,
/sensors.htm?filter_tags=@tag(%2bbandwidthsensor,%2bsnmptrafficsensor)
will show a combined list containing only sensors tagged bandwidthsensor and snmptrafficsensor.
Filter Sensor Lists by Tag and Type
You can combine these calls also with the filters that are applied when you choose Sensors | By Type | ... from PRTG's main menu. For example,
/sensors.htm?filter_type=ping
shows a list of all sensors of the type "Ping".
Combine this with tags if you wish. For example,
/sensors.htm?filter_type=ping&filter_tags=@tag(myTag)
will show a list of all sensors of the type "Ping" which are tagged myTag.

I was wondering how you would add an and/or filter to the tag list.
For example, I have three tags and I want it to be:
TagA and (TagB or TagC)
I'm having trouble coming up with the formatting for this. Any help would be appreciated.

I'm very sorry, but combinations of AND and OR are not possible in these tag filters on lists.

Hi
Are we able to exclude specific tabs from the filter ?
Something like if Critical and not vpn
If not Ill look at putting in a feature request as I think this would be a valuable addition
Thanks

For the @tag- filter function you can use a - as operator for NOT. So
-vpn
should exclude all vpn-tagged sensords.

Is it possible to use NOT filtered tags in maps? It seems not to work for me.

I'm afraid I can't quite follow, can you explain with more details please?

In maps, I can filter by tags to show only certain sensors, but I would like to show all sensors except a few selected ones which I tagged for this purpose. In the sensor list view I can do that using - sign, but this does not seem to work in maps.

It should also work with maps, it's just a - infront of the tag:
-tag
I just successfully tried it on a map on my PRTG. '-cpu' as tag filter removed all entries on a Top 10 "Least used CPU Sensors" (before it did show 2 sensors).

I found the error, thank you.
