Any complicated system need to be monitored. LMA (Logging Monitoring Alerting) Fuel Plugins provides complex logging, monitoring and alerting system for Mirantis Openstack. LMA use open-source products and can be also integrated with currently existing monitoring systems.
In this manual will be described complex configuration include 4 plugins:

  • ElasticSearch/Kibana – Log Search, Filtration and Analysis
  • LMA Collector – LMA Toolchain Data Aggregation Client
  • InfluxDB/Grafana – Time-Series Event Recording and Analysis
  • LMA Nagios – Alerting for LMA Infrastructure

(more details about MOS fuel plugins: MOS Plugins overview
It is possible to use LMA-related plugins separately but the are designed to be used in complex. In this document all examples are from cloud where all 4 plugins are installed and configured.

LMA DataFlow

LMA is complex system and contains the follwing parts:

  • Collectd - data collecting
  • Heka - data collecting and aggregation
  • InluxDB - non-SQL database for time-based data, in LMA it is is used for charts in Grafana
  • [https://www.elastic.co/ ElasticSearch - non-SQL database, in LMA it is used to save logs.
  • Grafana - Graph and dashboard builder
