How to Start, Stop and Search For failures or Issues in Skype For Business Server AKA CsClsLogging AKA Centralized Logging

tree

 

I have a video which complements this blog located at YouTube. Have a look if you need help-

Logging in Skype for Business has a lot of potential. However, it is made difficult by the need to use The command line. If you remember the Skype 2015 Resources tool kit, This kit contains CLSLogger And Snooper. This CLSLogger should be made part of the SFB product. It is a natural thing to do to help users gets the logs they need, without the size that command line logging can yield. If you Download CLS logger, I will show you in just a few steps, how to get the logs you need. Download the Performance toolkit from:

Microsoft.com CLSLOGGER

Once you have the tool in your hand, you simply run the default install, and the tool will be created in the path:

Start the application C:\Program Files\Skype for Business Server 2015\Debugging Tools\ClsLogger.exe

Before I even get started, I will tell you three times during this article, “Ignore the middle tab”. This is for advanced use. If you

Are just starting out, only pay attention to the first and third tab. Your going to run a trace and get a copy of the trace. That is

Our goal.

You are going to see three tabs, Ignore the Edit One

Begin at Tab1 Stop and Start Scenario

YOUR GOING TO RECEATE YOUR ISSUE DURRING THIS STEP. BEGIN REPRODUCING AS SOON AS THE START SENARIO BUTTON

IS PUSHED. MABYE 5 SECONDS AFTER-

 

  1. 1. Choose the Stop and stop scenario (1) See Figure 1 Below
  2. 2. Choose “Incoming and outgoing call” from the Drop Down. This choice will work for most issues because we just need the S4 and Sip Stack Flags (2)
  3. 3. Check the Front end server- or what ever sever you want logs from. you should collect FE servers and Edge logs separately (3)
  4. 4. Choose “start scenario”, when you are ready to recreate issue. In our case we are making a call to another user. (4)
  5. 5. Once the call is finished chose “stop scenario” (5)

Now Tab 3 the Search CLS LOGS

(Skip tab2 in the middle, it will only confuse things)

Use Figure 2 below to help with instructions

Go to search CLS logs tab. (ignoring the Edit Tab) and follow these steps

1. Log File Folder: Output is going to be where you want your output log to be placed

2. Log level- We usually want “All”

3. Start and stop Time is most important. we want to include the period where the issue occurred. So be early and log a little longer to make Sure you captured the issue

4. Like I said generally select Sip Stack and S4 for SIP calls or IM’s (Voip yes I said it)

5. Finally, You should only select what you captured, an if you captured only front end traffic. Capture Edge traffic in a separate trace

  1. That’s It! Your log should be on your Desktop, or wherever you specified!

Now you should have your log. You can open the log with SNooper, which is in the same folder as CLSLogger. Good Luck and I hope this

was helpful.

Snooper tool is located in C:\Program Files\Skype for Business Server 2015\Debugging Tools\Snooper.exe. By Default.
