I need to monitor the overall system health of my client’s system. What metrics would you suggest I monitor in order to detect problems with gateway, the OPC connections, DB connections etc. Any suggestions?
You’ll want to monitor the cpu/memory load of the system and the database server at least.
I also monitor that the Ignition service is running and what % of system resources it is consuming at any given time.
We use Nagios for this task, but What’s Up would work just as well, or any of a number of other programs.
Most of our PLCs have watchdog bits that I monitor and alert on from inside Ignition as well.
Thanks for the pointers
