Is it possible to move netflow sensors from one probe to another without data loss?

Votes:

0

I have a single probe/core server setup that's starting to reach it's load limit. We suspect it is the custom netflow sensors that are causing the extra load (two sensors with more than 20 channels each and large filters; data comes from 2 routers with up to 200Mbps sustained traffic). We're thinking about adding a second probe for doing the netflow collection but can't afford to lose any historical data since we use it for billing. Is it possible to: build the new remote probe; add it to the list of IPs the routers export netflow data to; move the sensor from old probe to new probe.

This seems like it would work, but I would like to know for certain before I propose adding another probe.

Dear Jim,

as you know, moving one sensor from a device to another is not possible, especially not in this case when the sensors are on probe devices. I'm afraid you can only try working around this with the Sensor Factory.

Since we would move all of our netflow sensors and since they are all under the same device, can we move the device from old probe to new probe without data loss?

Dear Jim,

if it would be a remote probe, it might be possible. However starting from the Local Probe, we'd say it's too risky.

Best Regards.
