I have 2 PI Server in collective and on each Server there is one Interface PerfMon (one on Primary and one on Secondary); interfaces are distinct (different pointsource, different id, not in failover).
I'm connecting to PI Collective (by default, the connection is established with the first member of the Collective): when I'm searching PerfMon tags of the secondary PI Server, all tags appear in I/O Timeout. If in the connection pannel I switch the member of the collective (so I proceed to connect with the second member) that tags appear with the correct current value.
I have to use this tag in a Coresight Display connected to AF Elements, so is necessary that on the first member all tags appear valuated correctly.
Could be something like a "trust" problem?
