DCDB

The Data Center Data Base (DCDB) is a modular, continuous, and holistic monitoring framework targeted at HPC environments.

This plugin implements the functions to report periodic metrics, report loops, and report events.

When the DCDB plugin is loaded the collected EAR data per report type are stored into a shared memory which is accessed by DCDB ear sensor (report plugin implemented on the DCDB side) to collect the data and push them into the database using MQTT messages.

Compilation and configuration

This plugin is automatically installed with the default EAR installation. To activate it, set it as one of the values in the EARDReportPlugins of ear.conf and restart the EARD.

The plugin is designed to be used locally in each node (EARD level) with the DCDB collect agent.
