Zabbix

Zabbix A system for monitoring and tracking the status of various computer network services, servers and network equipment.

For data storage it uses MySQL, PostgreSQL, SQLite or Oracle. The web interface is written in PHP. ZABBIX supports several types of monitoring:

• Simple checks - can check the availability and response of standard services such as SMTP or HTTP without installing any software on the monitored host.
• ZABBIX agent - can be installed on UNIX-like or Windows hosts to obtain data about CPU load, network usage, disk space, etc.
• External check - execution of external programs. ZABBIX also supports monitoring via SNMP.
