fsmon vs fs_usage
alvarofe opened this issue · comments
It's true that the output from fsmon is nicer than fs_usage but it doesn't lose any event.
$ sudo fs_usage 43

From fsmon I had to change different backends any of them were working except fsevapi but is giving the following output, quite hard to make head or tails from it.
The process that I am monitoring with the purpose to explore the tool is syslogd. I wouldn't mind to look at this issue and working on the output, but busy these days. Will try in the following weeks
fsusage uses the fsevapi afaik, thats because output is the same in both ;)
each filesystem backend supports different events.
the output i get from fsmon -b fsevapi is exactly like the one in others, so i cant reproduce this issue
