Minimizing CPU Utilization of audisp Plugin

[Osama Elnaggar]

Hi,

I'm currently working on a Python audisp plugin. My main routine looks
like this:

if __name__ == '__main__':

try:
...

aup = auparse.AuParser(auparse.AUSOURCE_FEED)
aup.add_callback(process_event, None)

while True:
for _ in fileinput.input():
aup.feed(_)
except:
...

While profiling my plugin, I noticed that 95% + of the CPU time used by my
plugin is used in fileinput.input(), waiting/reading from input

Is there any way to lower this or preferred way to poll/read?

Thanks

I don't do much if any python programming. But in C, all examples include a
select in the event processing loop. Python has a select module. There are
examples on the internet about how to use it. One is here:

There are other examples.
