Is there a size limitation on a policy trace file?
There is a limitation of 1 million characters or about 1 MB in size which auto rotates.
If you are missing information in the policy trace, you may need to limit the scope in what you are tracing.
Example code added to local policy to limit the trace to a particular client IP address <ip addr> and to URL domain of "example.com"
<proxy>
client.address=<ip addr> url.domain=example.com trace.request(yes) trace.destination(trace1)
<ssl-intercept>
client.address=<ip addr> url.domain=example.com trace.request(yes) trace.destination(trace1)
Reference: Use policy tracing to debug access denied errors or website accessibility issues
To open the debug file generated by the policy trace, go to Proxy IP address - https://X.X.X.X:8082/policy. You should see policy trace you named above (trace1)
