[Perfparse-users] Re: [Nagiosplug-help] PerfParse v0.09

[Ben C. <Ben...@ro...>]

Morning Michael,

PerfParse does not need or use Perl, Nagios does not need perl to work=20
with PerfParse.  I do not use Perl my self :)  However, some plugins do=20
use this.  You will have to consult the Nagios experts for more=20
information about this.

Secondly, MySQL.  Yes, you do really need MySQL version 4.  This has=20
transactions, which PerfParse uses to ensure your data is entered=20
correctly, and where problems to occur, these cause the program to break=20
without adding rubbish to your system.  I am sorry that SUSE 8.1 does=20
not have MySQL 4.  You can however install and build the raw system by=20
downloading the source from mysql.org.  This is pretty easy to do, and=20
will ensure you always have the latest version.  If you do this, please=20
deinstall MySQL binary files first, but not the 'data' :)

The environment I use is a RedHat Linux 7.2, which has been personally=20
upgraded by downloading raw source from various sites.  The box is about=20
1GHz with 512 memory and 40GB hard disk.  We have only about 30 hosts,=20
but over 300 services, running Nagios and PerfParse on the same system.=20
  The load of the box (if I look at the daily average from PerfParse=20
over last month :) is 1.035.  Well below the 2.5 advised limit for a=20
UNIX box.

If you want to lower the load, here are some tips (Garry, if your=20
reading, you may want to add to HOWTO :):

- Use two box's, one for Nagios, one for PerfParse.
- Use as much memory as you can get hold of.
- Set the 'Delete Policy' to 'Always' for any metrics you do not want to=20
work with.  They will then be ignored.
- Use the '--no-raw' option on PerfParse.

In the future there will be other options to control the load through=20
PerfParse, like deleting data only daily, which will also help.=20
Probably version 0.10 or 0.11.  Please watch for later release versions.

There are no real figures as to what specification is needed for a=20
certain service count.  I would be very interested in knowing what your=20
load is with your 500 services.

Kind regards, Ben.
