[Perfparse-users] Question about the perfparse pipe method

[John V. <lus...@gm...>]

We've been using the perfparse pipe method successfully for over a year now=
.=20
We're very happy with the whole setup.

However I have a need where I need to create rrdtool style graphs with=20
multiple values. What I would like to do is monitor the pipe with an=20
external process and insert the data into an rrd file for creating these=20
graphs. I don't want to run another monitor and double the number of times =
I=20
poll a server. I'm getting the data I need from Nagios just fine.

From my own tests with creating a pipe and running two tail sessions agains=
t=20
the pipe, only the last attached reader gets the data from the pipe. Is=20
there a safe way to from the perfparse pipe so that I don't interrupt=20
perfparse and cause missed perfomance data?

This is probably more of a general Linux question but for some reason, the=
=20
answer seems to be eluding me.

Thanks.
