New plugin for checking Cacti (rrd databases) transfer rates

[Paa.listas]

I don't understand. What I do is to check the data already collected by
Cacti and based on that info generate a warning or a critical status.
Cacti's RRDs are the data in which I base the decisions about network
traffic.

Thanks after all. I will try to see more the link you attach to the mail.

Hello,

Please note that Cacti isn't the best tool to use with Nagios, look around
PNP ( www.pnp4nagios.org ) which is a perfdata handler.

Hasta luego

transfer rates

Hello,

	Because of my work I had to write a little PHP script to integrate
with Nagios. It works checking local RRD databases (Nagios and Cacti on same
computer for example) for incoming or outgoing transfer rates. 

I think that this script can be useful to others, so I want to known if it
can be enhanced / corrected to be included in a future release.

The script, a configuration command file definition, and a demo host are
attached to this e-mail.

Saludos. Pablo.

$ check_rrdtraf.php -h
This plugin will check the incoming/outgoing transfer rates of a router,
switch, etc recorded in an Cacti rrd database By Pablo Armando (c) 2009

Usage:
        check_rrdtraf [-h] -f rrd_file -I|-O -w min_warning -W max_warning
-c min_critial -C max_critical

Example:
        check_rrdtraf -f /var/lib/cacti/rra/mx_1_traffic_in_239.rrd -w 1000
-W 2000 -c 4000 -C 4500 -I

This checks if the input traffic (-I) is between 1000 and 2000kbps.
If this is true a warning message will be fired. If the input traffic is
between 4000 and 4500kbps then a critic message will be fired

-h   Show this help
-f   full path to rrd database
-I   check input traffic from incoming data source
-O   check output trafic from outgoing data source
-w   start of warning range - Required
-W   end of warning range   - Required
-c   start of critic range  - Required
-C   end of critic range    - Required

The values for -w, -W, -c, and -C are expresed in kbps
