We are currently offering monitoring solutions that include the following:
-Monitoring of 1 server and up to 3 processes/variables (SMTP, Disk Space,http,etc.)
-24 Hour e-mail notification
-Customizable Pager/SMS notification. Can have 24x7 notification, business hours notification, weekday only, etc.
This a great addition because it will be on a different network than your servers and can tell you if a link to your network or servers is unresponsive, even if the server is still running.
If you are interested please contact us for more details. As always, I would be happy to answer any questions.
We have 2 servers dedicated to monitoring. These are not beefy boxes, but are more than adequate for what they do. We have servers are 2 seperate networks with some custom scripts. Basically you are not getting pings from 2 servers, but one server. Each server monitors the other. When a problem between the 2 are detected, it runs scripts that deal with the problem and determine where the problem lies before it starts blowing errors.
