CeeNOC is a product that utilizes an array of network monitoring tools to check publicly accessible hosts and alerting you in the case that a check fails. In keeping with Unix principles, we choose the right tool for the right job. This means that we are not implementing some overextended package without the ability to scale CeeNOC. We have a redundant infrastructure that will let you know when your services and daemons are not responding. We check at the interval of approximately every ten minutes.
CeeNOC allows you to have your hosts monitored without the hassle of maintaining an infrastructure remote to your systems. In the event that your hosts are unresponsive after two attempts, you will be notified at email addresses you provide. If you are using more than one email address for notifications, we recommend that you utilize email aliases so that you can easily change the people or positions being notified.
We have been monitoring our direct clients' hosts for years now. We are aware of outages on their premises and for their servers quickly, and often notify the clients before they know of problems. We are proud to extend this service to those outside of our direct client periphery.
Monitoring methods include:
Monitoring by TCP or UDP with a specific port number will check if the particular port is listening. For instance, you might want to see if your mail server is up, we would check port 25/TCP. This only illustrates that the service is listening on that port, however, and will not guarantee that your mail server, in this case, is functional.
Checking by TCP or UDP port is very flexible, and can be adapted for any public service. For details of the standard applications by port and protocol, see the Internet Assigned Numbers Authority list of port numbers.
We can also check for particular text strings on a WWW site. This will indicate that the particular page includes the specific text string. For instance, you might want to check header or title strings like "Mr. Coyote's Acme Corporation." This will indicate that the relevant text string has not changed, and that the site is responsive.
A more robust check to perform for WWW pages that are static are checksum comparisons. We catalog the checksums of each of your WWW site's pages, then compare the online checksums to our offline database of the verified checksums. If any change is noted in the checksum comparison, you are alerted.
CeeNOC will expand with more checks in the future.
