Starting your journey with FusionReactor for ColdFusion monitoring should be smooth, but like any powerful tool, there can be early bumps. Below are some of our users’ most common issues and how to solve them quickly, so you can focus on optimizing your ColdFusion applications.
🔑 Problem: I can’t find my FusionReactor licence key
Solution:
Your licence key is sent via email after starting a trial or purchase. If you missed it, just log into app.fusionreactor.io, click your profile in the top-right, then go to Account. For on-prem licences, use the On-Premise tab in the top navigation.
🔄 Problem: I need to move my license to another server
Solution:
Uninstalling FusionReactor from your old server frees the license seat. If you can’t uninstall it, deactivate the license via the on-prem UI (default port: localhost:8088) or from the cloud UI’s On-Premise tab. Need help during a migration? Request a temporary key from sales@fusion-reactor.com.
🧵 Problem: My SQL queries are being cut off in logs
Solution:
Long JDBC queries get truncated by default. To fix it:
On-prem: Go to JDBC > Settings > SQL Text Limiting and raise or disable the limit.
Cloud: Add this JVM argument to your instance:
-Dfr.observability.trace.value.limit=1000 (adjust as needed).
📧 Problem: I want to receive email performance reports
Solution:
Set up SMTP in the on-prem UI under FusionReactor > Settings > Email Settings. Once working, enable reports under Plugins > Active Plugins > FusionReactor Reports, and choose the frequency that works for you.
🚫 Problem: I’m getting a “no seats available” error
Solution:
This means your licensed seats are maxed out. Go to the On-Premise tab at app.fusionreactor.io and click View Activations for each license. You’ll see what’s using each seat so you can deactivate old or unused instances.
