Question

I need to count how many error events are logged under “Application” and “System” of a remote computer using powershell. I have started this but not got to far.

Get-EventLog -computername COMPUTER -Logname Application -EntryType Error | Measure-Object -Sum Entrytype | Format-Table Count

This is very rough right now and the two problems so far is that the above command only does ONE type of log at a time, and
the format of the table isnt very useful.

Id like to have extra headers so it outputs Computername, Entrytype and Count.

How can I get powershell to list both events and have extra headers with the table?

Answer 1

$info  = foreach ($log in "application", "system") {get-eventlog -ComputerName $computername -LogName $log -EntryType error }
$groupedinfo = $info | group-object machinename, entrytype
$groupedinfo | select @{N="Computername";E={$_.name.split(',')[0]}},
                      @{N="EntryType";E={$_.name.split(',')[1]}},
                      count
