JunOS firewall data


I have a customer with Juniper firewalls feeding data to a v10.3.4 . Until now we've had the standard set-up:

Data Source VendorJuniper Networks
Data Source ModelJUNOS – Structured-Data Format (ASP)
Data FormatDefault
Data RetrievalSYSLOG (Default)


However, the customer is under the impression that this is not sending all the available logs to the SIEM. He says that there is an option for "stream" data, which would pick up more. I think that what he's describing is documented here, at


The existing data source will not work with this (he tried, we had to tell him to revert the change). Is there any plan to support this? And if not, how would I raise a request to get it onto the planned improvements list?


Many thanks

Re: JunOS firewall data

Hi James,

In the Junos CLI commands for set security log stream command, do they have an option for entering structured-data?

The following is a normal syslog command on Junos:

set system syslog host structured-data

I would like to know whether we have an option to enter 'structured-data' after the host field or the filename as below.

set security log stream S1 host structured-data

set security log stream S2 file name file1 structured-data

If yes, you can try the above command & check if it is working.

If not, customer will have to be submit a PER as per KB60021.

Also, please note the structured data syslog format should be as in the below link:
