The following is the collectd config that I am running on my RHEL 7 kvm hypervisor. This is not meant to be an all inclusive config for collectd, rather I am looking to gather basic performance metrics on my hypervisors and VMs.
Note that I have disabled selinux, as I am running these hypervisors in my lab. Do not do the same in your production environments.
1 #setenforce 0
I also edited /etc/selinux/config as shown below. Again, this is for non-prod/test envs. Do not disable in production
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
Also note that I have already configured the EPEL repo.. again, not production.
EPEL repo installed via the command below
1 rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
First a couple of steps to get us up and running. We need to install packages
1 # yum -y install collectd collectd-virt.x86_64 collectd-rrdtool.x86_64 collectd-sensors.x86_64 collectd-smart.x86_64 collectd-netlink.x86_64 collectd-ipmi.x86_64
We also need to write our config.
You can pull my config using the gist below
We now need to enable and start collectd
#systemctl enable collect
#systemctl start collectd
