Since real time syslogs can be managed with a conditional, then can be used to help debug odd edge cases in your application that you wouldn’t be able to find before. Here’s a cool example:
To create a log feed for all 500 errors, as well as some extra information that’s valuable for tracking down these errors, create a new log feed with the following format string:
- Format string
%h %l %u %t %r %>s server.datacenter req.http.Fastly-Client-IP geoip.region req.http.Fastly-SSL
This would go in the conditional section of a newly created log feed (click the settings gear to the right of the new log to access this)
resp.status > 499 && resp.status < 600
