The following options are available to our Co-Location customers for monitoring bandwidth usage. As all accounts are billed on a 95th percentile billing structure, spikes will have little impact on monthly usage; while sustained peaks often result in overage charges. We provide you with 24/7 access to view your bandwidth usage. Our server updates every 5 minutes and, once logged in; you can display data by daily, weekly or monthly usage. You may access your usage by logging into the server at:
Enter the login information that we provided to you in your welcome email to gain access to the machine. Then enter your username in the box and generate your report by clicking the “here” link that appears. You will then be able to see your usage. You can check this server as often as you like to ensure that your bandwidth usage is at an acceptable level for you.
To avoid any bandwidth overage charges, we suggest you keep an eye on your bandwidth usage. If logging in and viewing your bandwidth on a regular basis isn’t something you can or want to do, we offer a bandwidth monitoring service that generates an alert email when bandwidth nears and/or surpasses a threshold of your choosing. This service is $25/month and can be easily setup upon request. Simply call or email us to get this set up on your account.
Alternatively, as you may already be aware, there are many free programs available for monitoring and alerting of bandwidth usage based on adjustable program settings. Some examples of these programs are:
Cacti - http://www.cacti.net/
MRTG - http://oss.oetiker.ch/mrtg/
PRTG - http://www.paessler.com/prtg - the freeware version should be more than enough for most customers’ needs.
With all of these tools at your disposal for determining monthly bandwidth usage, customers can calculate upcoming overage charges and, if needed, increase the monthly commitment and eliminate bandwidth overage fees entirely.
