Accessibility Monitoring of Server Services
Server Monitoring – Basic Description
The monitoring of servers is being ensured via Nagios monitoring system. Monitoring of a wide range of services – from standard services like HTTP, FTP, SMTP, POP, SSH, IMAP up to the monitoring of the server load, free disk capacity, free memory resources and more via SNMP protocol.
How and how often do we measure?
When in error-free status check-ups are usually set to 5-minute-intervals; when an error is detected the interval is being decreased to 1 minute. It is possible to set a timeout at every service after which the service will be reported as in critical condition (5 seconds implicitly) or as in full error condition (10 seconds implicitly). Our administrators are being notified about dropouts immediately, namely both by e-mail messages and XMPP/Jabber communication protocol.
Consumer Awareness
In order to inform the customer e-mail communication or also notifications by the help of SMS or Jabber messages is being used. It is also possible to set and agree on specific formats of e-mail messages, e.g. it is possible to set that our monitoring shall reboot the server in case of a dropout, call the customer and alike. The customer can be sent availability graphs and reports of his server or individual services on request – for example graphs concerning the disk load, the server load progress, the RAM load, the HTTP protocol response and others.
