I have an existing HTTP Content sensor and have appended additional channel items [] to the http response. Now i wanted to adjust the sensor to add the additional channel items [] to the existing probe. I guess i could recreate it, however is there another way?

Hello,

the HTTP-Content sensor should have a field called "Number of channels" in its settings. Please try this one.

best regards.

Thanks for your help. Unfortunately "Number of channels" is only available when you create the sensor, once created there is no ability to add/remove a channel.

Sorry, you're right, then you would have to create a new sensor.

As you can see, there haven't been further requests to this, so yes this is not changed.

It would be great if you could add channels as things change over time, i.e. disk gets added or an new schedule task gets added and so on.

Issue with recreating the sensor is that you lose all historical data which is bad for SLA scenarios and you lose unusual capabilities.

What would be great would be if we for i.e. advanced console XML sensors to be able to re-create sensor but keeping historical data.

Same question here.

I've several SQL sensors, where channels might be added (actually, I have several of those sensors where I have to add channels already). So yeah, it would be extremely helpful if we could add channels AFTER creating the sensors!

I'm afraid the same holds true indeed for the SQL Sensors. I'll put it on the wish list to improve this.

I join the club - in general any sensor should be adjustable with the channels. I understand that I would not see historical data for those additional channels before they have been added - but yes - I have that issue with several sensors that rely on advanced EXE / XML data etc.

E.g. DHCP scopes monitoring, the second I add a scope I need a separate sensor... unless I add blind channels in the beginning - what is confusing if you look at the sensor as well..

It would be nice to have this as a feature! Would be a great help and make many things more variable.

Removing channels as well!

I would like to chime in on this as well. We run Cisco switches, and when we add a fiber SFP, we can't add/rediscover this sensor to add the tx/rx channels for the new fiber module. Asking us to delete and recreate the sensor is not acceptable, as we lose all of our fiber tx/rx information for the other channels.

We need a fix/solution for this.
