On Friday, March 24th, between 13:30 and 15:30 UTC we observed abnormally high CPU load on the AlertFox production database server, necessitating a restart. While the restart of the database was successful and did not result in any loss of data, the process responsible for classic (HTTP) measurements did not fully initialize all sensors after

On Friday the 22nd, between 15:38 and 16:43 UTC, we noticed an unexpected error occurred on AlertFox backend. Some transaction sensors (iMacros) results might not have been saved during that period of time. We modified some settings on our side to prevent this happening again. All our apologies for any inconvenience this may have caused. Classic was left unaffected.

As promised, here’s an update on the issue we had on April 30th. Between 8:40 GMT and 22:00 GMT, one of our measurement components failed which took classic monitoring down. Being a web monitoring company, we do not fail to notice the irony that our monitoring took very long to bring this problem to our

Starting next week, we will update our classic sensors’ back-end architecture to match our transaction (iMacros) sensors. Besides improved scalability and performance, this will allow for future feature extensions (like additional monitoring locations).

No action is required from our customers.

How to Alert on a Group of Sensors

Thursday, 10 April 2014 by

Have you ever wanted to be able to receive an alert if one or more sensors are failing simultaneously? For example, let’s say you have three sensors monitoring some aspect of your site, and each sensor is configured to run in its own region. These sensors will already alert you if there is a problem

While our administrators are dealing with the AlertFox database (in order to overcome potential performance issues) some customers report failures when accessing reports or running “Test Now”. We are aware of this problem and are trying to fix it. Please refer to this post for updates. [Update] The underlying cause has been identified and a

Measurement Server Update: iMacros 9.0.6

Tuesday, 28 January 2014 by

Over the next few days we will update our measurement servers to take advantage of  iMacros version 9.0.6. This update does not require any changes to your sensors.

This morning, our tech team has detected some malfunction wrt. immediate sensor tests of iMacros sensors (“Test Now” on the sensor settings page) which seem to report wrong data. We will disable this functionality until the issue has been resolved. Please refer to this blog post for updates on this matter. [Update] The development crew
