A few days ago I got an error with my ColdFusion 2018 server which I had not seen in many years. I had seen this error when running ColdFusion 9 many years ago but not for some time. I could not figure out what I had broken. After some googling it seemed to be that […]

In FusionReactor 8.1 we introduced the Ephemeral Data Service (EDS). This service allows you to register your transient / short-lived instances to the Enterprise Dashboard so they can all be monitored from a single location.

This is attached as a linked transaction (indicated by the small linked chain […]

FusionReactor is used to monitor many ColdFusion servers but our support team keeps seeing an issue that FusionReactor cannot solve. This issue is that some of the ColdFusion classes, for the template cache, become corrupt.  This corruption isn’t caused by ColdFusion itself but when users or Windows Updates shut down the running instance.  If ColdFusion […]

FusionReactor and Your ColdFusion Queries In my last article on FusionReactor, I talked about slow pages and how the tool helps you find them.
