  • Monitor EMS - trigger a trace

    Any ideas how to monitor the ems messages and if a certain message occurs trigger a ptrace script?

    Create an EMS filter on the message number/SSID you want to monitor. Create a program in C that starts an EMSDIST process with the filter and wait for events. When you get such an event, use PROCESS_LAUNCH_ to start ptrace. The EMS Manual has examples of this, IIRC.
