trend-out - no CA Network Flow Analysis data available

[Jose Romero]

Dear Community, I have the following situation: I have a device:

Model: mx10003
Junos: 22.4R2-S1.6

The trend-in section is displayed, but not the trend-out section.

Hi Jose,

Have you verified if the interface is configured to export flow information in borh directions?

Some vendors export only on ingress traffiic so the only wat for NFA to report the out traffic is calculating from the ingress traffic of other interfaces

Have you take a look on this?

Thank you for your response. I would like to inform you that the version I am using is 20.2. The user has shared the following lines of his configuration with me.

Hi Jose,

I see you are using a very old unsupported version. I strongly recommend you to upgrade

Apart from that, I cannot confirm if the flow export is configured properly. What vendor and model is this?

Have you verified the device is export flow for egress traffic in this interface? You might do it using a network capture

The vendor is as follows:

Model: mx10003
Junos: 22.4R2-S1.6

I have another device that is the same model and apparently configured the same, and it does display the information.

Hi Jose,

does this KB apply to your case?

https://supportportal.juniper.net/s/article/MX-Sampling-output-interface-in-logical-system-not-supported-for-inline-flow

Can you make a network capture to confirm the flows are exported but maybe the output ifindex is not properly populated?
