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.
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. SELINUX=disabled # 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. SELINUXTYPE=targeted
Also note that I have already configured the EPEL repo.. again, not production.
EPEL repo installed via the command below
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
# 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
