Though everything is configured correctly and you have successfully added vCenter 4.x or standalone ESX 4.x to Veeam Extensions as a Monitoring target,
no data is shown in SCOM and you can see "Veeam VMware Collector: VMware connection is unavailable" alerts .
Additionally, the following errors are logged in the vmspi.log file (you can export logs as described
here):
1) In case vCenter 4.x is connected:
