Install collectd 5.4 on Centos 6.x and make it spit out cool metrics. Copied from http://linuxdrops.com/install-collectd-statistics-collecter-on-centos-rhel-ubuntu-debian/ and tweaked for your and my pleasure. For all other cool options, check the provided link.

gistfile1.sh

#!/bin/bash
# Perform installation as root
# Install prereqs

yum -y install libcurl libcurl-devel rrdtool rrdtool-devel rrdtool-prel libgcrypt-devel gcc make gcc-c++

# Get Collectd, untar it, make it and install

cd collectd-5.4.0

# Copy the default init.d script

# Set the correct permissions

chmod +x /etc/init.d/collectd

# Start the deamon

service collectd start


# NOTE! FQDN lookup is enabled by default. This might give you troubles if you'r running on Vagrant or some cloud server
# Check /var/log/messages for something like "Looking up "<yourhost>" failed. You have set the "FQDNLookup" option, but I cannot resolve my hostname...
# The fix is easy, just set "FQDNLookup   false" in /etc/collectd.conf

@joegoggins In CentOS the packages are yajl and yajl-devel (no need for the lib prefix).

cracking little script. Saved me writing something similar :)

If you're on a new box and don't have the Perl tools installed you might need those too.

perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker

if you want the notify_email plugin to work, be sure to include libesmtp and libesmtp-devel and ./configure with --with-libesmtp=/usr/lib64

👍 This script is good, Just in case if anyone wants to compile collect for ALL THE PLUGINS with all dependencies, follow this link: http://giovannitorres.me/enabling-almost-all-collectd-plugins-on-centos-6.html (Contains list of all dependencies) :)

rrdtool-prel should be rrdtool-perl

For some reason tcpconns metrics are not being sent at all.
I'm running CentOS6 and I used this command to install the collectd:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --libdir=/usr/lib64 --mandir=/usr/share/man --enable-all-plugins

All metrics are being sent except of tcpconns, any suggestions?

there's a typo in the first yum install command. Instead of rrdtool-perl you have rrdtool-prel
