LMD fetches Livestatus data from one or multiple sources and provides:
- A combined Livestatus API for those sources.
- A cache which makes Livestatus queries a lot faster than requesting them directly from the remote sources.
- A enhanced Livestatus API with more useful output formats and sorting. See list below.
- Aggregated Livestatus results for multiple backends.
- A Prometheus exporter for Livestatus based metrics for Nagios, Icinga, Shinken and Naemon.
So basically this is a Livestatus In / Livestatus Out daemon. Its main purpose is to provide the backend handling of the Thruk Monitoring Gui in a native compiled fast daemon, but it should work for everything which requires Livestatus.
