Élenchos: Check cpu

A Élenchos command for checking CPU usage.

Installation and Configuration

Install Élenchos if not already installed:

cd /opt

mkdir elenchos
cd elenchos

python -m venv .venv
. .venv/bin/activate
pip install elenchos

mkdir bin
ln -s ../.venv/bin/elenchos bin/elenchos

Install the check:cpu plugin:

cd /opt/elenchos
. .venv/bin/activate

pip install elenchos_check_cpu
./bin/elenchos gather-commands

Create a configuration file /etc/nrpe.d/check_cpu.cfg for nrpe:

command[check_cpu]=/opt/elenchos/bin/elenchos check:cpu <arguments>

Possible arguments are:

• -i, --interval=INTERVAL The interval between the two CPU statistics gatherings in seconds. [default: 2.0]
• -w, --warning[=WARNING] The warning level for CPU user in %.
• -c, --critical[=CRITICAL] The critical level for CPU user in %.

The warning and critical CPU levels are optional. Hence, one can use this Élenchos command solely for gather statistics.

Finally, restart the nrpe daemon:

systemctl reload nrpe
