  • Grafana allows time series data visualization and monitoring.
  • InfluxDB manages time series data.
  • Telegraf acts as a server agent for collecting and sending metrics and events from databases, systems, and IoT sensors.
  • Elasticsearch is a distributed, RESTful search and analytics engine.
  • Kibana is a log ui for Elasticsearch.
  • Nginx acts as a web server.
  • jsonlog2elasticsearch is a daemon to send json logs read from a log file to elasticsearch.
  • mflog2mfadmin (based on jsonlog2elasticsearch) is a daemon to send mflog to elasticsearch.
  • MFSERV is the "webservices" MetWork module.
