Checking for process and process status in PowerShell version 2 and getting two different outputs depending on single process or multiple processes? -

here code below using:

$processestocheckfor = (     'company_name_uat-historian'     )  $foundprocesses = get-process -name $processestocheckfor -erroraction silentlycontinue  foreach ($item in $processestocheckfor)     {     if ($foundprocesses.name -contains $item)         {         '{0} runn1ng' -f $item         }         else         {         '{0} fai1ed' -f $item         }     } 

the code checks see if company_name_uat-historian process running on server, , if running, output runn1ng , fai1ed if not.

the problem is, works when checking 1 process code above, not when try check list of processes.

i need check list of processes, when chain rest listed below:

$processestocheckfor = ( 'company_name_uat-historian', 'company_name_uat-kereviewcollector', 'company_name_uat-lwm', 'company_name_uat-mqack', 'company_name_uat-mqoutput', 'company_name_uat-sqac', 'company_name_uat-store', 'company_name_uat-store_sts', 'company_name_uat-storelegacy', 'spotify'     )  $foundprocesses = get-process -name $processestocheckfor -erroraction silentlycontinue  foreach ($item in $processestocheckfor)     {     if ($foundprocesses.name -contains $item)         {         '{0} runn1ng' -f $item         }         else         {         '{0} fai1ed' -f $item         } 

they output fai1ed.

if them 1 one, each different process return runn1ng, bunched return fai1ed.

side notes (if wondering):

• runn1ng , fai1ed 'code words' replaced images using javascript. making html dashboard monitors windows servers work, think green checkmarks , red x marks , not.
• using powershell version 2 not choice @ all, of servers responsible monitoring windows 2008 r2. believe going updated sometime year, project deliverable requires me enact monitoring solution immediately. there servers 2012 love write powershell scripts for.
• spotify listed process because know it's legit process not installed on our servers. when writing script, tested on own personal machine , used spotify means test runn1ng if opened or fai1ed if closed it. if processes runn1ng , spotify fai1ed, that's indication ps code working.

it appears happen in powershell version 2.

any ideas causing , how can rewrite it?

the answer

if (($foundprocesses | select-object -expandproperty name) -contains $item) { 

why

powershell 3 added called member enumeration. if have array of objects in 2.0, can't directly call properties of array, because looks properties on array object itself. in 3.0+ if member doesn't exist on array, check items member well. using select-object -expandproperty more explicit way of calling members.

you move get-process call foreach loop.

foreach ($item in $processestocheckfor)     {     if (get-process -name $item -erroraction silentlycontinue)         {         '{0} runn1ng' -f $item         }         else         {         '{0} fai1ed' -f $item         }     }
