Website Monitoring

Website Monitoring

Developed By BlueRabbIT

Compatible with WHMCS v8.8

Server monitoring does not do all the job

You all know the problem. Yes, there is server monitoring, and it reports that all is fine, but a customer website is having problems and your customer notices before you do.

There are many things that can go wrong, while your server monitoring is telling you that all is fine. There can be many reasons:

  • The customer misconfigured something
  • An automatic Wordpress plugin update broke the website
  • The customer forgot to update its SSL certificate so it expired
  • The customer has the domain registered elsewhere and forgot to renew it in time
  • Maybe the customer hosts DNS elsewhere and he only added a www record but no record for the main domain
  • And so on and so on...

This is where the Website Monitoring addon for WHMCS comes in!

Developed with web hosters in mind

We were unhappy with our monitoring situation and wanted to provide better service quality to our customers. So we made the module ourselves!

Our module will automatically scan all active subscriptions and their freely configurable domain aliases and subdomains from your WHMCS system, and alert you if any of these problems arise:

  • Bad HTTP response (4xx or 5xx)
  • Domain works but www does not, or the other way round
  • IP not resolvable
  • IP does not resolve to the designated server IP
  • SSL certificate invalid

This way you can proactively check what is going on and contact the customer if necessary.

Your customers will thank you for the good service you provide!

Plenty of features

  • Integrates nicely into the WHMCS design
  • Widget for the WHMCS Admin Area front page showing you all subscriptions currently having problems.
  • NEW! Ability to enable/disable monitoring on a per-product, per-server, per-client and per-subscription basis
  • View monitored subscriptions and their statuses, and see the details of each subscription along with its monitoring change history.
  • Allow your customers to see the status of their websites directly from the client area (optional)
  • Per-domain configuration on which checks to enable/disable
  • NEW! Also monitor web hostings that are not configured in WHMCS
  • Granular configuration and logging capabilities allow you to use the module just how you want it.
  • Notify admins and/or customers via e-mail about problems with their domains
  • NEW! Integrates with the WHMCS Notification System
  • NEW! Parallel processing with real-time monitoring in WHMCS
  • NEW! View logs directly from the Admin Area

Actively maintained

This product is actively maintained and we use it ourselves.
