Callbacks - how to query number of calls and time spent in user callbacks?
AnsweredHi,
are the number of user-callback calls and the total time spent in user callbacks stored as model attributes so that I can easily query them?
Or is it only possible to obtain these values by defining private counter/clock variables that I increase in my callback function?
Thank you! Best, Pia

Hi Pia,

Yes, currently it is only possible via private counter/clock variables which have to be increased in your callback function.
Alternatively, you could read the log message via the MESSAGE callback and filter it for the number of callbacks.

Hi Jaromił Najman,
Are there plans to make the time spent in user-callbacks available as a model attribute? It's a bit of a workaround having to approximate it with my own clock variable.

Hi Niels,
There are currently no plans on implementing these attributes in the next release. However, the plans may change in the future.

Hi Jaromił,
Thanks for your quick response! A shame, but understandable. I'll make do with my own counters for now.
Best, Niels
