What is it good for?
ClusterCockpit is a framework for job-specific performance and power monitoring on distributed HPC clusters. The focus is on simple installation and maintenance, high security and intuitive usage.




ClusterCockpit overview
ClusterCockpit consists of
- the web user interface and API backend cc-backend
- the node agent cc-metric-collector
- and the in-memory metric cache cc-metric-store
All components can also be used individually.
Node metrics are collected continuously and sent to the metrics store at fixed intervals. Job details are provided by an external adapter for the batch job scheduler and sent to cc-backend via a REST API. For running jobs, cc-backend queries the metrics store to collect all required time series data. Once a job is finished, it is persisted to a JSON file-based job archive that contains all job metadata and metrics data. Finished jobs are loaded from the job archive. The metrics store uses cyclic buffers and stores data only for a limited period of time.
