Sonata's monitoring system gathers, analyzes performance information from NS/VNF and provides alarm notifications, based on alarm definitions which have been defined from the users. The architecture of the system is based on data exporters and a monitoring server. Data exporters sends monitoring data from NS/VNFs to monitoring server which collects, analyses, stores data and generates the appropriate notifications. In generally monitoring server consisting of a rest api interface, an alerting mechanism (based on prometheus.io), a timeseries DB and a real time notification service.
SONATA's monitoring system based on following services:
-
Monitoring manager: Is a Django/rest-framework server combined with a relational database (mysql,postgres ect). Monitoring manager relates each metric in Prometheus DB with Sonata's monitored entities like NS/VNFs, vms and VIMs.
-
Prometheus server: Prometheus is an open-source systems monitoring and alerting toolkit, its a standalone server not depending on network storage or other remote services.
-
Prometheus pushgateway: Despite the fact that the default approach from prometheus is to retrieve the metrics data by performing http get requests to exporters (containers, vms etc). The usage of http post methods from exporters to Prometheus has many advantages like no need for exporters to implement a web socket in order to be reached from prometheus, no need to reconfigure prometheus each time a VNF is created or changes ip address etc.
Each micro service of the framework is executed in its own Docker container. Building steps are defined in a Dockerfile of each service
