argus-2.0.0Q, RA clients that buffer and dump data.

[Carter Bullard]

Hey Chris,
In the argus-2.0 package we have a few clients
that do buffer records and write them all out
when they are done, rasort(), ramon() and ragator().
But they terminate, at the time they "flush" all
their data.

However you maybe able to do what you want with
the existing package.  I would be this:

   ra -S remotehost -w ra.out &

This generates a persistent ra that is gathering
records from remote host and putting the records
it gets into the file ra.out. Have that running
constantly.  The file ra.out is your buffer.

Now every 10 minutes you can have a shell script
that mv's ra.out to another filename, say tempfile.
The persistent running ra (above) will recreate
ra.out when it goes to write out its next record
from the remote argus record.  All the ra* programs
will recreate their output when they realizes that
it no longer exists.

This strategy gives you your 10 minute argus data
buffer.  Now you can use any ra* file to process
it.

It also would be very straight forward to add this
feature to one of the ra* programs, but ...
I'm trying to imagine what your application.  That
might help me to understand how I can help.

Is the desire to aggregate common records together
before you "burst" them, or do you want to sort them?
What are they flushing there data to, a pipe or a
socket, stdout or a file?
