conncurrnet connection information LTMs

show sys traffic

If you're looking for APM CCU (concurrent user) licensing information, SOL13267 talks about what actually consumes a license (since not every connection does).

After looking at multiple ways of looking for the actual CCU license counts, we ended up with this command,

echo -e 'get tmm.license.global_connectivity\r' | nc 127.1.1.2 11211

VALUE tmm.license.global_connectivity 0 2
37
END

There is an article that was related to this here. It's in French, and focused on logging during the APM session start flow, but it's worth looking over.

Just take the total number of connections every 60 seconds. Then calculate the difference between consecutive readings and divide by 60. That's connections per second. You'll need your SSL license to be about twice your PEAK connections per second (averaged over 60 second period as above).

For APM. Grab a lab edition (US$100) and run one up. Best education you can get is doing it yourself and learning from your mistakes.

sessions per second ssl offload. We are currently seeking a quote for the apm license and our architect was looking for that info.

Would tmsh show sys traffic work ?

output of command:

what are some good free resources/link to get skilled up on with APM if training is'nt an option

Thanks again

You talking APM? (Sessions). Or connections per second on SSL offload?

(Either way you can get the numbers from either tmsh or snmp. Or iControl (REST or SOAP). You just have to get the numbers from a different place, depending on what you actually want...
