Introduction
Abiquo relies on a complex infrastructure with many distributed services that must be monitored on health and performance. This document is a guideline about which elements you must monitor on your installation to assure service level and proactively detect possible failures before your end customers do.
Monitoring technology
We let you choose your prefered monitoring platform, nowadays most major monitoring techonolies has the capability to alert about services outages alongside retrive and graph performance metrics, so it is up to you to decide which one you will use.
Services to monitor
Next you will find a relation of elements to monitor on every server on a distributed installation. We will try to detail both process name, port where the service would be listening to and also interesting parameters to get metrics values.
Abiquo Server
This server would host Abiquo API, UI, websockify and M services, it would also have the queue system RabbitMQ, Redis and MariaDB database.
