PtTimer Widget

I have a PHAB application that uses the RT Trend widget to display a short-term, medium-term, and long-term trend graph. I have 3 seperate PTTimer widgets that drive the data update. One with a repeat of 1 sec, one with a repeat of 10 sec. and one with a repeat of 3 minutes. This application has been running for around one year and I have recently determined that the long term trend graph is no longer updating. Is there a way for me to see the associated OS level timer associated with each of these widgets so I can determine whether or not the timer is firing? I’ve looked at sin rt and sin timers but don’t know if this shows the timers associated with the widgets or how to determine which would be associated with which widget. Has anyone experienced this before? Is there any way to see if my timer is still firing?

Thanks for your help.
