An independent vendor with deep knowledge on the subject says this: plixer. Thanks but this was already pointed out in the comments above. Counter sampling performs periodic, time-based sampling or polling of counters associated with an interface enabled for sFlow. The sole difference being "NetFlow is Cisco proprietary, sFlow is not" isn't exactly correct. This includes network equipment vendors that already support NetFlow including Cisco, along with router vendors like Brocade now Extreme and in many switching products including those from Juniper and Arista. Flow-based monitoring provides significant advantages over other network monitoring methods. To get more info on how NetFlow and sFlow are used see these Kentik blogs.
However, this seems to provide SFlow sampling and the router shows the JFlow license as unused. What is the configuration to get JFlow. Juniper Network switches run both HP's sFlow flow sampling technology and J‑ Flow, Juniper Networks' own flow sampling technology.
Overview. Juniper Network switches run both HP sFlow flow sampling technology and J‑Flow, Juniper Networks' own flow sampling technology.
SFlow is a packet sampling technology where the switch captures every th packet configurable per interface and sends it off to the collector.

NetFlow v9 and v10 IPFIX send periodically template message which tells how to read the samples, this template is very flexible and can be extended arbitrarily. Flow-based monitoring provides significant advantages over other network monitoring methods.
JFlow is a IP traffic flow sampler technology used by Juniper manufactured routers and switches.
JFlow is considered a flow sampler. In this NetFlow/J-Flow/IPFIX/sFlow era, there is no need to settle with only knowing Specify sampling rate and where to send the J-Flow data.
What is the impact on the accuracy of flow record analysis?
It is also v4 and v6 agnostic, unlike NetFlow, which forces you into an uncomfortable compromise depending on what type of data you want to receive. NetFlow v9 and v10 IPFIX send periodically template message which tells how to read the samples, this template is very flexible and can be extended arbitrarily. Sorry we are away, but we would love to hear from you and chat soon! Cisco devices try to aggregate flows you can think of them as conversations and then export information about them to a collector.

Google got Looker. September 11, So which is better?
How is sFlow different from netFlow, and how is each supported by different vendors?
Configuring Cisco Flexible NetFlow and Juniper j-Flow v8 discusses the purpose, limitations, accuracy and the overhead of flow sampling. Here is a trick part, as in this step you need to configure the inline-jflow, so that sampling mechanism and the J-Flow are executed in the forwarding engine.
But open source tools are….
Let us show you in 30 minutes, with your own data. Testing performed by Kentik indicates that even at sampling rates as low aslower bandwidth traffic patterns are discernible even in high throughput networks.
monitoring What is the difference between netFlow and sFlow Network Engineering Stack Exchange
Netflow is a Cisco proprietary protocol and as such is not supported by anything other than Cisco devices. This requires memory to cache these. NetFlow statefully tracks flows or sessionsaggregating packets associated with each flow into flow records, which are then exported.
