Need help about Netflow

This is the document I used for configuring jflow v9 on my Juniper devices.  It's a bit more of a process than a Cisco device, but you get some great stats out of it.

The good stuff starts on page 7.

This document from a Thwack user also appears pretty good and accurate.  Check it out.

JFlow v9 IPv4 on Juniper SRX

Hope that helps.

Best is to post your issue on Juniper forum to get config assistance and quicker response.

The docs I linked to above will give him (or her) all the info they need for adding jFlow to their devices.  Since most every Juniper device runs JUNOS, the links provided will cover their needs.

I can confirm that the info provided in the link that goes directly to Juniper does work.  I've used it many times.  And the second link appears to be correct as well.

The great thing about the Thwack community is that we've all likely used and configured (and broken then fixed) the devices our IT brothers and sisters are asking about.  So while it is good to go to the manufacturer for info, I like to think we don't turn anyone away for asking a relevant question.  And our response time is rather quick here too (as evidenced by my post 30 minutes prior to yours) and not long after their OP.

Can any one help i want to configure on SSG5 or SSG550 which is using screen os plz. help to configure NET FLOW

Unfortunately, Juniper doesn't support Netflow or jFlow on ScreenOS devices.  Below is a link that goes to the KB document from Juniper that explains it a bit.
