It's working!
But it seems that my inventory script (or my approach to get this data) has to be redesigned. I need somehow faster inventory results (nightly scheduled) from customers infra (> 10 VCs, >2 DCs, >100 CLSs, > 600 hosts, > 1000 datastores, >10.000 VMs) and dump them into SQL DB.
The downside: If one of VCs is having problems then the script stops responding.
Every time i contruct something i take the following into consideration
Method 1: Loop through an array of Virtual Centers, one at a time
$VCs= @(“vc_server1”,“vc_server2”)
Foreach ($VC in $VCs) { `
Connect-viserver $VC
.script...
Disconnect-VIServer $VC –confirm:$false
}
Method 2: Connect to an array of Virtual Centers, all at the same time (trying to achieve with script)
# Set PowerCLI to MultipleMode
Set-PowerCLIConfiguration -DefaultVIServerMode Multiple -Confirm:$false
connect-VIServer -Server “vc_server1”,“vc_server2”
.script...
Disconnect-VIServer * –confirm:$false
Its seems that i have to go for the third method (because both previous approaches take about 5 hours to get the needed info). Method 2 affects all get-view commands.
Method 3: Trigger every VC at certain scheduled time, let the Powercli script run locally against 'own' VC and dump the results to central SQL DB. i tested and within 1-1,5 hour the results are retrieved. But it's not 'agentless' data collection.
I didn't test it with (4th method) powershell multithreaded option (Add-job). Would that be an alternative for 'agentless data collection' approach?
Anyhow i will (try to) combine this script with additional stuff from your article: http://www.lucd.info/2011/11/14/storage-views-datastores/
in order to get additional info per datastore: [Size_Snapshot] ,[Size_vDisk] ,[Size_Swap],[Size_Other],[Size_Shared],[Multipathing],[ConnectivityStatus]. That would make the output complete for different internal usage purposes. The Storage CapMan want's to have it very fast. For me a huge challenge to combine it without degrading in execution time.
Thank you for your help! You're my (and my friend's) Hero!
