CloudLinux LVE Exporter for Prometheus

LVE Exporter - A Prometheus exporter which scrapes metrics from CloudLinux LVE Stats 2

Help on flags:

  -h, --help  Show context-sensitive help (also try --help-long and --help-man).
      --web.listen-address=":9119"
              Address to listen on for web interface and telemetry

Tested on Cloud Linux 6, 7 & 8.

Running as root (for testing only, not recommended for production)

# ./lve_exporter --web.listen-address=":9119"

Running as Systemd Unit (with non-root user) - preferred method

• Download lve_exporter in /usr/local/bin/lve_exporter
• Create a regular user

# useradd --system --shell /bin/false prometheus

• Create a sudoers file, which will allow executing of cloudlinux-statistics without asking for password

# cat <<EOF >> /etc/sudoers.d/prometheus
prometheus ALL=NOPASSWD: /usr/sbin/cloudlinux-statistics --json
EOF

• Create systemd unit

# cat <<EOF >> /etc/systemd/system/lve_exporter.service
