Additional Citrix Servers Pop Out in Dashboard although no TCAM is installed

Not only no TCAM is installed, I also didn't configure these unknown IP in the 'User-Mapping' Setting of AMD using RUM Console. (And in case you wonder these might be the IP of other NICs on the same server machine? no they are not)

But here it is:

But yet these IP of citrix seems to be.....auto-discovered? Anyone know what might be happening? Because I am thinking even if, even if it means citrix servers would get auto-doscover, it shouldn't be this less (only three, in my screenshot)

If you have auto discovery enabled on AMD, then servers will be discovered indeed. If ICA decode is enabled, these will start to be monitored with the ICA decode and thus they will show up on the Servers report. TCAM doesn't have to be installed on these servers, with TCAM you wouldn't see infrastructure metrics like CPU or memory, but all user activity with the server will be monitored.

Hi Kris, thanks for the answer.

How about the dash in this screenshot? Any idea what that means?

Thanks @Kris Z.,

If there is dash when looking at performance perspective, I might be able to comprehend it because there might be insufficient traffic volume (or no traffic at all like you've mentioned).

BUT why would I get a dash when looking at host-resource perspective? since these metric are from TCAM, it should be all-or-nothing, there is no possibility of not-enough-data or no-data-in-current-monitoring-interval isn't it?

Indeed TCAM is all-or-nothing. If it works, it would be sending its data for the monitored server. One case where I can imagine some misalignment is if the Citrix server is multi-homed. I'm not sure how would it show up then - the ICA server seen by the decode and the server reported by TCAM may be different servers I guess.

No performance measurement made, so report can't determine the server status. Why there was too little of this traffic seen is hard to say - you need to examine it on the Operation Explorer reports and charts.

Hi Kris,

I am not looking at performance perspective, but from CPU or Memory perspective.

Also, if I understand your first comment correctly there would be no grey tiles in performance perspective (would show color even if no TCAM, as long as there is enough traffic seen). Whereas for other perspective, we can only have non-grey color if TCAM is installed. Isn't is correct?

"If you have auto discovery enabled on AMD, then servers will be discovered indeed. If ICA decode is enabled, these will start to be monitored with the ICA decode and thus they will show up on the Servers report. TCAM doesn't have to be installed on these servers, with TCAM you wouldn't see infrastructure metrics like CPU or memory, but all user activity with the server will be monitored."

Those tiles represent servers detected by the decode. TCAM may be not installed on these servers. TCAM metrics don't color these tiles. Color may be grey when there's no data to decide on color, e.g. server has been seen in past monitoring intervals, but is inactive in the current monitoring interval.

Hope this helps
