[Dev][Stratos] [GSoC] Window time interval size
Hi All,
Currently we are using 1 minute as the window interval time. Shall we
change it to 10 minutes?
Thanks

Yes, Raj is correct.
Pranavan, please note. We need our sliding window as 1 minute. i.e. we will
be generating curves in each 1 minutes, considering the events received
last 10 minutes.
Thanks.

In other words, window length is 10 minutes, but sliding interval is 1
minute.

Hi Reka,
I guess we are increasing window time interval to 10 minutes. But we will
be sliding the window every minute. So CEP will publish events every 1
minute. Isn't it Lahiru?
Thanks.

Hi Lahiru/Pranavan,
If the CEP window interval changes to 10 min, then i hope that the decision
from CEP will be received by Autoscaler also in 10 min interval. In that
case, how will the prediction work? Are we predicting the load also before
10 minutes? If the prediction time is less than 10 minutes, then we might
not have enough events in autoscaler to predict at some point? WDYT?
Thanks,
Reka

Thanks for the update Lahiru. I will proceed with that time interval.

Re: [Dev][Stratos] [GSoC] Window time interval size

Yes, we receive health stat publisher in cartridge agent sends events in
each 15 seconds. Therefore we will receive about 40 events in 10 mins.
This is a good number to find the curve.
Thanks.

Hi Lahiru,
I am working on EMA implementation for the events coming from cep. If we
take window interval of one minute, I will be receiving less number of
events. If we change it to 10 minutes, we can receive more events. Then the
prediction will be more accurate. Shall we proceed with that?
Thanks
