[Users] Monitoring on failure

I want to implement a monitor system when there is a failure route. At first I think to send an snmp message when there was a failure route, but the snmp module is frozen, isn't it? Now I want to write a line in a special log file. So I want to have the normal log file for monitor information (call stablish, call released, etc..) and another log file for errors. I though in use the exec module to inser the errors in the error-log file in this way: exec_dset("echo Error_failure_route >> file_error.log"); Does anyone have a better idea to do this? Because I think that the exec module is slower than use xlog. It is possible to execute that command in background? That openser does not stop the execution until the command has finished.
