Netdata

The lightweight open-source Netdata Agent acts as a distributed database, enabling the construction of complex observability pipelines with modular, Lego-like simplicity.

[8] This allows for fully automated and unsupervised anomaly detection, and with its intuitive APIs and UIs, users can quickly perform root cause analysis and troubleshoot issues, identifying correlations and gaining deeper insights into their infrastructure.

Starting with v1.12, Netdata collects anonymous usage information by default and sends it to Google Analytics, a feature which can be disabled via manual configuration.

[9] When executing the daemon on Linux using the netdata command, threads are generated that collect information from each resource, using internal and/or external plugins.

Netdata is currently maintained by nearly 400 contributors,[12] all helping (at various levels) to serve the thousands of individual users and businesses[13] who utilize this tool.

[17] The all-time most popular feature request appears to be adding support for running multiple freeipmi jobs from the same Netdata.
