Might be better to send a request that nagios renames the files, then you
can process them then delete them?

Subject: [Nagios-devel] Deletion of the performance data log files.
Dear group,
I have a problem parsing the Nagios performance data and wonder if any
member can suggest a solution. These have the default file names
'serviceperf.log' and 'hostperf.log'.
I wish to parse and delete these every minute. But I cannot delete them
as Nagios holds the file open. Stopping and starting Nagios every
minute is not really an option.
Really I want to pass a command to Nagios to request the deletion of
these files. However, if there is a delay between Nagios getting the
command, and Nagios deleting the files, information will be lost.
Because my program is sitting waiting for the deletion without parsing.
Ideally, I would want Nagios to write to a tmp file, then on getting a
command, close the file, move it to the true file, and open up a new tmp
file for it's self. Or get Nagios to continuously close the file after
every write, making it delete-safe. But this might effect performance??
If any member has any ideas, I would be extremely interested.
Kind regards, Ben.
