Hi All,
I was wondering if someone can give me some hints on the below please.
I have a flowgraph running continuously demodulating some off air signals and spitting out meta data about the parameters, calculated SNRs, BER, freq offset estimations, etc. That meta and output data is parsed regularly and saved to a database.
However, sometimes it is either meta missing or data or both. I am convinced that the flowgraph either stalls or crashes. I need to capture it where exactly but first I want to develop a tool to monitor the flowgraph to now when it crashed or hanged.
So I want to add a hearbeat somewhere which I can monitor and know exactly that it is not running anymore. Does anybody have any ideas of what would be the best way to do it? Can I use something from the library for this?
Any suggestions will be appreciated.
Many thanks,
Milos
