Overview
We use the Zabbix open-source IT monitoring software suite as part of our internal downtime and performance monitoring infrastructure. This software allows us to continuously monitor servers for potential downtime or diminished performance and alerts the Support team so that the matter can be quickly addressed.
The Zabbix testing suite is comprised of two applications: the Zabbix Server and the Zabbix Agent.
The Zabbix Server application is installed on several centralized testing servers and is used to perform the testing on servers being monitored.
The Zabbix Agent is an application or service commonly installed on servers and is used to perform certain types of testing (processor, memory, disk, and others). It also allows for communication between the server and the Zabbix testing server.
Note: The Zabbix Agent is only installed on servers equipped with the Premium Monitoring add-on product.
