Calculating EPS and Throughput for Decoders

[Anonymous]

Hey everyone,

What's the best way to calculate the EPS and Throughput (average) for Log and Packet decoders.

I'm implementing new Virtual devices and want to size the disk appropriately for what retention time I want.

Thanks.

If virtual devices, i think later on you can add/adjust the storage size if required.

To calculate, need to assume, for example, log message size 300 byte, each device sends 2 or few msg / s.

There isn't a method currently I'm aware of built into the application. I've heard rumors of 10.5 and maybe 10.6 having the actual EPS statistics but until then this is the method we have used from a centralized SSH server like SA head.

http://<decoder name, ip or alias>:50102/sys?msg=statHist&force-content-type=text/plain&expiry=600&time1=2014-Dec-08 00%3A00%3A00&time2=2014-Dec-9 00%3A00%3A00&include=%2Fdatabase%2Fstats%2Fsession.rate%2C%2Fsys%2Fstats%2Fcurrent.time" > eps2.txt 

You may have to modify the query time to pull it and you keep in mind this is against a decoder, its a snapshot for that "state" and thus to get averages you'll need to dump and write something homebrew.
