Tandberg endpoints cannot establish calls over Juniper Routers

This is a nasty little issue. On my private network, suddenly some endpoints would refuse to establish calls made over or . would be:

channel unacceptable
487 / Request Terminated
480 / Temporarily Not Available

Not particularly helpful information. After all the packet sniffing and diagnostic checks, it appeared packets were being rewritten or dropped between the endpoint and our VCS. The culprit here is Juniper’s ‘’ for SIP and H323 traffic. I don’t have the time not to figure out exactly why or how it was breaking my calls, but i do know that in my case, it wasn’t needed. Disable the SIP and H323 ’s (in the SRX web UI under Configure -> security -> . The endpoints will start working again after your reboot them and allow them to re-register to your .

Monitoring Flexlm usage with Zabbix

Flexlm can be a hard thing to accurately measure and monitor. Luckily, the output from lmutil can be used to display . First thing to do is locate the lmutil binary and try to get it to run. I use Flexlm for autodesk on and ESRI on (centOS).

Windows:
This server seemed to want the license file specified. You may need to launch the GUI tool and watch the status bar for the path to it. This is what mine looked like:

"c:\program files\autodesk network license manager\lmutil" lmstat -c "c:\program files\autodesk network license manager\license\license.lic" -a

Linux:

/home/esri/arcgis/license10.0/bin/lmutil lmstat -a

That will spit out the current license usage for all your products. To isolate the numbers we want to monitor, we will be piping the output into some other commands like find and cut.
I recommend using the for windows http://gnuwin32.sourceforge.net/. These examples use the built-in ‘find’ utility, and a ‘cut.exe’ tool i found googling around. I had overlooked the gnutools when I first set this up. My mistake can be your gain. With gnutools, it will be easy to isolate the output you want using ‘grep’ and ‘cut’. First, isolate the line you are looking for with grep. You will have to figure out what feature code you want to monitor. mine looks like this:

Windows:

"c:\program files\autodesk network license manager\lmutil" lmstat -c "c:\program files\autodesk network license manager\license\license.lic" -a | find /i "64300acd_f:"

Linux:

/home/esri/arcgis/license10.0/bin/lmutil lmstat -a | grep ARC/INFO

now that you have the right line,  you can trim the extra characters with ‘cut’. It will take some experimentation to get it right.:

Windows:

"c:\program files\autodesk network license manager\lmutil" lmstat -c "c:\program files\autodesk network license manager\license\license.lic" -a | find /i "64300acd_f:" | cut -c 62-64

Linux:

/home/esri/arcgis/license10.0/bin/lmutil lmstat -a | grep ARC/INFO | cut -c 59-61

The output now should be only the number of licenses being used.

To allow zabbix to monitor this value, we need to create a ‘UserParameter’ read up on it here: http://www.zabbix.com/documentation/1.8/manual/config/user_parameters. This is what the parameter looks like on my servers:

Windows:

UserParameter=licenses.autocad.used,"c:\program files\autodesk network license manager\lmutil" lmstat -c "c:\program files\autodesk network license manager\license\license.lic" -a | find /i "64300acd_f:" | cut -c 62-64

Linux:

UserParameter=licenses.arcinfo.used,/home/esri/arcgis/license10.0/bin/lmutil lmstat -a | grep ARC/INFO | cut -c 59-61

Once you have the userparameter created on the license server, restart the agent and add an item in zabbix to begin collecting values.
