I don't think this exists...

Can MF automatically generate a message when a given message type starts being throttled by limit?

E.g., category "Update" has a limit of 5, so we would have something like

MyApp: Update 1
MyApp: Update 2
MyApp: Update 3
MyApp: Update 4
MyApp: Update 5
MessageFacility: Msg-i Throttle "MyApp: Category 'Update' has been limited"
MyApp: Update 10

And, maybe, if timespan was set, when the timespan was hit
MessageFacility: Msg-i Throttle "MyApp: Category 'Update' limit reset"

Please due date with a grain of salt. (7.47 KB) Ron Rechenmacher, 11/07/2017 01:08 PM

This may reasonably be done as a drive-by as part of the implementation of issue #3571.

I would like to see this feature implemented.
Silently dropping log messages is usually not good, IMHO.
Additionally, (perhaps assuming no exponential back-off), a message should/could be added after the
limiting (associated with the first non-limited message) that indicates how many messages have
be limited/dropped.

Minor note: the end-of-execution summary should always tell you how many times a message was issued, not how many times it was printed.

Message statistics, which include the number of times messages from a given category were logged or printed, can be displayed by setting the outputStatistics configuration parameter to true for any given destination.

Implementing the above feature is straightforward, the question is whether such a feature should be scheduled soon, due to our current demands implementing multi-threaded art. Please let us know urgent this feature is.

#7 Updated by Ron Rechenmacher over 3 years ago

Sorry I didn't notice this earlier.
It doesn't seem to be too urgent in the grand scheme as another issue I just filed is higher priority.
I can't seem to get the statistics to print.
I've tried:
debugModules : ["*"]
destinations : {
xxx: {
categories:{default:{limit:4 timespan:1 reportEvery:2}}

But this does not seem to work.
I'll attach an example program
