The megware_eureka collector reads power and other metrics from Megware Eureka machines via u20. If the u20 tool is available for your machines, it's possible that this collector is compatible. If you don't have access to u20, please contact your Megware sales person.

You can test the collector compatibility by running the following command:

$ u20 values --read GET_MPS_POLL_VALUES

If this returns a JSON with energy, voltage and current readings, you're fine.

In addition, u20 typically requires root to run. In order to run cc-metric-collector without root priviliges, you can enable use_sudo. Add a file like this in /etc/sudoers.d/ to allow cc-metric-collector to run the required commands:

# Do not log the following sudo commands from monitoring, since this causes a lot of log spam.
# However keep log_denied enabled, to detect failures
Defaults: monitoring !log_allowed, !pam_session

# Allow to use u20 for Megware power readings
monitoring ALL = (root) NOPASSWD:/usr/bin/u20 values --read GET_MPS_POLL_VALUES
