[cisco-voip] Query TcdSrv.ClientsOnline Programmatically

[Patrick Humpal]

Wes,

 

I ended up writing a small VB script that polls every 60 seconds and
sends alerts to HR when the ClientsOnline falls below 1.  Another
helpful utility is Solar Winds WMI Monitor (which is free).  I
configured it for:

 

Win32_PerfRawData_CiscoTcdSrv_CiscoCallManagerAttendantConsole.ClientsOn
line

Win32_PerfRawData_CiscoTcdSrv_CiscoCallManagerAttendantConsole.ClientsRe
gistered

 

HR can now see in real time the count of online AC users and the # of AC
instances registered with CM.  Still working on the log parser for
client side logs, but this is a decent hack for now.

 

Thanks again for your assistance.

 

Pat

Hello,

 

We're currently running Call Manager 4.1(3)sr8a and I've been asked to
provide alerts when the number of Attendant Console users falls below 0.
Initially, this seemed like an easy task: enable RTMT Alerts for "Cisco
Call Manager Attendant Console ClientsOnline" (TcdSrv.ClientsOnline) and
send notification to the appropriate users.  However, RTMT does not
allow you to filter by date (only start and stop times; nor does it
consider time of day routing) so it would generate alerts on the
weekends or holidays when AC users would never be online.

ws: RTMT with CM 7.x and later allows time based alarms I believe.
PH: 4.1(3) allows for time, but not date or day of week 

 
My next step was to look into AXL.  I created a simple PHP script to
query the AXL service, but again, there is no TcdSrv.ClientsOnline
available so it's kind of pointless to use SOAP.

ws: The counter is just a perfmon counter. It should be available by
normal windows perfmon poll or by AXL Serviceability API.  Not sure if
AXL serviceability included perfmons in 4.x, it certainly does in 5.x
and later.
PH: I looked through both AXLAPI.wsdl and axlsoap.xsd that are provided
with 4.1(3), but ClientsOnline is not available.

 
Instead I took a different approach creating a performance counter to
run every minute and log the number of clients online.  The log file is
mapped to a CIFS share where I have a cron job that greps the last line
looking for an instance of 0 users:
 
"03/30/2010 15:35:07.546","1"
"03/30/2010 15:36:07.547","0"
"03/30/2010 15:37:07.547","1"
 
While this works and will send an alert out during business hours I
wanted to extend this a bit to provide more useful information.  For
example it would be nice if you could see which users were currently
online and who the last user was to go offline.  Looking over the
"Performance Objects and Counters" documentation it doesn't look like
you can query for specific ClientsOnline:

 

http://www.ciscosystems.biz/en/US/docs/voice_ip_comm/cucm/service/4_1_3/
ccmsrvs/ssappdxc.html

 

Is there an easier way to do this short of writing a log parser to
collect/grep the AC logs from each AC user's PC? 

ws: Client information is not readily available.  You can parse the
serverside AC logs to get the information but that is about it.  
PH: Still looking for a location: C:\Program
Files\Cisco\CallManagerAttendant\logs has the standard ac.out.log and
ac_j.out.log log files but lacks the AC user information the client PCs
have.  I've enabled detailed trace level for JTAPI.


If I missed something in the Developer docs please don't hesitate to
point it out. Thanks!

ws: Nope, this is a hole in AC. What you are looking for is more
advanced user reporting which is a feature of IPCC.
PH: IPCC looks like a treat but licensing is pricey.  Plus we wouldn't
need the IVR functionality.
