I recently had to run some monitoring commands to gather information while a backup was running. So I used Powershell.<\/p>\n\n\n\n
I needed to SSH on to the FAS and run the following:<\/p>\n\n\n
\nset -privilege advanced\nstatistics aggregate show\nstatistics cache flash-pool show\n<\/pre><\/div>\n\n\nSo why should I do that when I can get Powershell to do it.<\/p>\n\n\n\n
Here is a quick bit of Powershell to SSH on to the FAS and run commands<\/p>\n\n\n\n
<\/p>\n\n\n
\n$FASCred = Get-Credential\n$Sess = New-SSHSession -ComputerName FAS01 -Credential $FASCred -AcceptKey\n\nInvoke-SSHCommand -SSHSession $Sess -Command "set -privilege advanced"\n\n# now we can loop\/re-run the following commands as often as we like.\n$SSHCommand = "statistics aggregate show"\n$res = Invoke-SSHCommand -SSHSession $Sess -Command $SSHCommand \n\n$res.Output | out-file "Aggregate.log" -Append\n\n$SSHCommand = "statistics cache flash-pool show"\n$res = Invoke-SSHCommand -SSHSession $Sess -Command $SSHCommand \n\n$res.Output | out-file "Flash-Pool.log" -Append\n<\/pre><\/div>\n\n\nI also had to run some other specific information gathering commands but that’s the process I used.<\/p>\n\n\n\n
Other statistical commands are:<\/p>\n\n\n\n
cluster statistics show<\/em><\/p>\n\n\n\nFAS01::*> statistics [tab]
aggregate cache catalog disk lif
lun namespace node port preset
qtree samples settings show show-periodic
start stop system top volume
vserver workload<\/em><\/p>\n\n\n\nIf I issued the command “set -privilege advanced”<\/em> on the SSH console I would need to confirm by entering “y”. The Powershell Invoke-SSHCommand -SSHSession $Sess -Command “set -privilege advanced”<\/em> also issued the “y” confirmation.<\/p>\n\n\n\nOccasionally I find I cannot do something in the Powershell Data.ONTAP module, so a fallback is to SSH on to the FAS, invoke a console command and return the output. <\/p>\n","protected":false},"excerpt":{"rendered":"
