Sensor Factory - SingleStat Panel reports same value for all channels

[SoarinFerret]

The Problem

Trying to pull different channels from the same factory sensor, all return with the exact same data when using the SingleStat panel. I have seen these issues, #65 and #78, but the work around on those did not seem to work for me.

Anyone have any ideas on how I could alter the metrics query below to accommodate this? Otherwise, I might make a pull request trying to fix it if I can hack something together, but I am not particularly great at JavaScript.

Additional Details

I'm monitoring a Hyper-V Failover Cluster with PRTG. I have SNMP CPU and SNMP Physical Memory sensors on each node in the cluster, but since I would like to monitor them as a group instead of individually, I used a Sensor Factory sensor to total up all the results.

Screenshots

Ignore the fact that the first two sensors data is slightly different, I just didn't screenshot them in time.

I am having the same issue. All the channels in Grafana show the same results of only Channel #1.

[SoarinFerret]

I ended up created separate factory sensors for each channel. Not ideal, but its what I have working right now.

I started working on a fork of this that I intended to submit as a pull request, but I'm not terribly proficient in JavaScript and am having issues getting it all working properly. Also, not going to lie, haven't looked at it in awhile either.

I'll update here if I ever get anywhere with it

+1 on this. Creating tons of factories is getting, shall we say... old. =)
