Network monitoring updated
May 18, 2007
One of the things that we never want to hear from our clients is that one of our servers or our network is down. Now we know that from time to time there will be network and server issues, but we never want to learn about it from a client. The only reply we ever hope to give is “we know about the issue and will have it resolved soon”.
To that end, we have recently updated our network monitoring systems. We actually have three redundant monitoring systems. Two are internal monitoring systems and one is a “public” monitoring system.
Internal Monitoring
We have two internal monitoring systems based on the open source software Nagios. One system is located in Texas while the other system is located in Georgia. By locating the monitoring “away” from our data center in Chicago we get a “client” perspective of response times etc. All major services are monitored including:
- Web
- FTP
- MySQL
- Server Load
- Disk free space
- Server Name
- Status
- Last Update
- Next Uptime
- Total uptime percent
- Uptime, Downtime and number of outages for this year Uptime, Downtime and number of outages for the last 3 months
- Uptime, Downtime and number of outages for the last 2 years
- Possible issue with uptime monitoring for July 2008
- Network issues
- RealMetrics uptime award - Aug `06
- Drazi outage - 29-Dec-2006
- Doreo Hosting Inks Deal with Righteous Software to Deliver Innovative Backup Solution
All services are monitored every 5 minutes. Doreo technicians are notified if any service fails tow times in a row.
Public Monitoring
We feel that it is very important to have a 3rd party monitoring our servers also. This gives clients and potential clients an unbiased view of our uptime. In the past we uses a monitoring service from Alertra. We have recently changed to using HyperSpin. We live several of the features of HyperSpin and were able to negotiate better rates with more frequent monitoring. Our servers are checked every 10 minutes by HyperSpin. HyperSpin utilizes a network of monitors across the globe.
Finally, you can view the status of our servers and services at http://www.doreo.com/status/ . The status web page shows a “traffic signal” like status for each service. Green means that a service is up and functioning while red means the service is down or not functioning properly. Finally there is a link to the HyperSpin data for each server. This pop up shows the following:

Got something to say?

Thanks Farzad!
We’ve actually had this monitoring in place for years. We just made some changes to the status page and switched from Alertra to HyperSpin for the public monitoring.
