Powershell Monitor - Scheduled Task - Previous alert statistic & Message as variables

rob.simms

Morning Thwack Community....

We have a scheduled task monitor:

$events = get-scheduledtask | where {$_.State -ne "Disabled"} | where {((Get-ScheduledTaskInfo $_).LastTaskResult -ne "0") -and ((Get-ScheduledTaskInfo $_).LastTaskResult -ne "267009") -and ((Get-ScheduledTaskInfo $_).LastRunTime -ge ((Get-Date).AddHours(-48)) -and ((Get-ScheduledTaskInfo $_).TaskPath -notlike "\Microsoft\*" ))} | Select TaskName$count = ($events.TaskName).Countif ($count -ge 1){    Write-Host "Message: Scheduled task has failed :" $events.TaskName    Write-Host "Statistic: $count"}else{    Write-Host "Message: No Errors reported"      Write-Host "Statistic: $count" }

This will alert when any non disbaled task has an exit code not of 0. The problem is, if a task has failed previously and then its in a running state during the next poll it will cause the script to assume the task is ok and thus cause it to produce a false positive. If LastTaskResult was actually the result of the last run and didn't display a running state we would be ok.

Is there a way of passing the previous message & statistic of a compant into a monitoring script? That way I could check if it was previously failed and ignore the running state - keeping the alert active.

Alternativly I could write the result to a file on the server and check via that - though I don't really like this way

Does anyone else have any other ideas?

Thanks

Rob

Probably the easier thing is to look for a windows event log of that failed task and monitor that.

Grabbing previous monitor states into current one isn't out of the box friendly. The only way I've heard of it done is with storing the previous state into a custom property through the API and reading it back out with a script.
