 How do you find out what a server process is doing?

Printer-friendly version

Looking in MONITOR.NLM -> Kernel -> Busiest Threads we see that one particular Server Process (Server 3 in the example, below) is particularly busy.

  NetWare 6 Console Monitor  12.01.9                  NetWare Loadable Module
  Server name: 'PINK' in Directory tree 'FLOYD'
  Product: Novell Netware, V6.5 Support Pack 3 - CPR Release

Go to NoRM -> Diagnose Server -> Profile/Debug -> and find the Server 3 process:

Execution Profile Data by Thread
Thread Name              Thread ID Thread State         Parent NLM   Execution Time
Server 3                 B2FE73E0  Waiting for work     SERVER.NLM   50.7 %
Server 2                 B2FDC360  Waiting for work     SERVER.NLM   44.4 %

Java_769 Watcher         450E0160  Blocked on Semaphore JAVA.NLM     0.1 %

Make a note of its Thread ID - in this case it is B2FE73E0.
 
Next, start up an NCP Trace on the server:
 
    ncp trace on ncptrace.txt
 
Which will trace all NCP calls to sys:ncptrace.txt
 
After tracing for a few minutes, turn it off:
 
   ncp trace off
 
Open up sys:ncptrace.txt in an editor and search for the Thread ID number you noted, above (B2FE73E0):
 
###### TRACE (Station=0 Task=10 Seq.=230, NCP 36 2) TID=B2FE73E0 ######
Scan NCP Ext. by Name (Ext#=NLS License Service Provider)
 
###### TRACE (Station=0 Task=10 Seq.=232, NCP 36 2) TID=B2FE73E0 ######
Scan NCP Ext. by Name (Ext#=NLS License Service Provider)

 
This shows which connection (Station=0) is using this Server Process and other NCP details.
