Could you please clarify "The VI-API is enabled only one collector in SCOM console"?
I installed Two Collectors:
In nworks Enterprise Manager , we configure the Loadbalance, so both both nworks collector are Active ( if only one is active the second will be inactive/standby). In my case , both collectors are Active
In SCOm Console (Monitoring), we have checking the following Views:
Under nworks VmWare
We have both collectors but only one have a VI-API Link
Under Virtual Infrasructure Collectors :
We have both collectors. but the column VI-API Link , this feature is enabled only for one collector.
_VIC Connections state:
Only one collector, (that have VI-API connection).
In Performance views, I see both Collectors, only in VIC Memory Usage, i see 3 instances (nworksVIC, nworksVIC1 and nworks64) for one collector and only one for the second.
For the enterprise manager server, i reinstalled the application as a windows xp sp2 programm with elevated previleges. it's installed correctly and the server appear now in SCOM console.
NB: all components cannot be installed as a Windows 2008 R2 applications even it launched with run as administrator option. the installation fail in last step of setup process. they can be installed as a Windows 2008 sp1 or windows xp sp2.
I checked, the nworksEvenlog one both Collectors, Both are collecting the informations from Vcenter Servers.
