Hi,
I believe you have followed this KB: https://kb.juniper.net/InfoCenter/index?page=content&id=KB19490&actp=METADATA
Can you please double check the below?
J-web will recognize the following settings as the syslog file that contains the traffic log:
file policy_session {
any any; // This can be any of [any/any, any/info, user/any, user/info]
match RT_FLOW; // Need exact the same match string for system in searching logs for policy
archive world-readable; // Requried
structured-data; // Preferred for fast searching when using filters
}
You can do a quick check on the file permissions and whether the RT_FLOW tag is seen in the file.
file list detail /var/log/<log-file-name>
show log log-file-name | match RT_FLOW
If you can share details of the log file configuration and above two commands it would help.
Regards,
Vikas
