DescriptionData logging and graphing tool for time series data infoThe storage layer (fixed size database) is called WhisperAn open source graph database built for real-time streaming and compatible with Neo4jFully managed big data interactive analytics platformQpenQM is a high-performance, self-tuning, multi-value DBMSIndustry standard data logging and graphing tool for time series data. RRD is an acronym for round-robin database. infoThe data is stored in a circular buffer, thus the system storage footprint remains constant over time.
