The key to good operations is being the first to know if something goes wrong.
I can add your system to my monitoring system (running on a RackSpace cloud server) and make it alert you directly, or I can build you your own monitoring solution.
Whatever solution you choose, you can rest assured that you will be the first to know when a system breaks down, when a web application stops responding, when a server's disk is close to full, or a machine is working higher than it's usual load.
Giving you the advantage to react before customers even notice.
I have made a Zabbix vs Nagios comparison if you prefer to know more about the technical aspects of monitoring.
I build your custom monitoring solution for an hourly investment of only £60/hr.
