Lync server 2010 – Monitoring Messages in Server

Hi Readers,

Recently We have faced issues with Lync performance, IM messages were getting delayed, some times Users were not able to Join meetings, some time connection to Lync was taking too much time.

On troubleshooting we have found that Messages in Server value on front-end server & other servers is going beyond limits ( 4000 –8000 ).

On further working on this issue it was found that edge servers are looping messages to internal Lync servers, as soon as we stopped the edge services, Messages in server value has gone below 30..

You can also see messages in server value by using Get-CsWindowsService

Till the time we resolve this issue , We came up with a workaround script to monitor this value.

Extract the zip file from below link, change the values accordingly and schedule the batch file to get alerts if value is above threshold.

$threshold = “100”

$fromadd = “Monitoring@labtest.com”

$email1=”Vikassukhija@labtest.com”

$smtpServer=”smtpserver”
$server_list=@(“serverDRP01″,”serverDRP02″,”serverFEP01″,”serverFEP02″,”serverFEP03”)

if you run it manually than it will show the result as below:
