Flow Designer Query: Flow reports not available

[velvizhisujatha]

Hi Team, 

I'm getting an informational message as "Flow reports not available. Check flow execution settings. Open Context Record". 

I have checked a property, 

Level of reporting data generated by the flow engine: com.snc.process_flow.reporting.level,  which holds the status as "OFF". I went through the docs but not able to get more clear picture on it. 

If I changed the option to "TRACE", it shows the execution details. 

Will there be any performance impact to the instance if I had to keep the option as "TRACE"? 

Kindly help!

Hi There,

Setting the system property to TRACE means:

 Developer Trace: Reporting is activated for all flows, subflows, actions, and steps (custom and base system).

Please Mark Helpful or Correct 🙂

Hi Daniel! 

Thank you for the response. Yes if its activated will there any performance impact because why is that property by default set to "Off".

TLDR: If you set reporting for all flows to TRACE, there will be performance issues, which is why it's not recommended in production. You can turn it on for select flows in production and it should be ok. 

This document gives a little more context: Activate flow reporting (servicenow.com)

It gives this warning near the bottom of the page:

Warning: Avoid enabling the Full reporting option on a production instance. Full reporting generates execution details for every flow and action run on the instance. Creating and storing these execution details consumes system memory and can lower system performance. Instead, only enable reporting for specific flows and actions or test them on a non-production instance.
