cgtop_mon

Get CPU and memory usage from systemd-cgtop and write to an InfluxDB database.

MemoryAccounting and CPUAccounting in systemd must be enabled for this to work. e.g., in /etc/systemd/system.conf set:

DefaultMemoryAccounting=yes
DefaultCPUAccounting=yes

and probably reboot (or activate it on a per-unit level via systemctl set-property ...). Note that memory values for already running services might be bogus until restarted when MemoryAccounting is activated mid-runtime.

Installation

• pip install .
• edit cgtop_mon.conf and copy it to /etc
• copy cgtop_mon.service to /etc/systemd/system
• systemctl enable --now cgtop_mon.service
