Loss and Latency API

Hello

 

We are using the Loss and Latency API to check the Loss and Latency of network interface. In the GUI you can still see a proper loss and latency, however if you use the API and do a request every minute, you get lots of None (which is no data)

 

param = {}
param['timespan'] = 800
param['uplink'] = "wan1"
my_latency_results = dashboard.devices.getDeviceLossAndLatencyHistory(my_serial,my_dst_ip,**param)

since i always check the last returned record with :
 
my_latency_wan1 = my_latency_results[-1]
 
Is this a timing issue between the meraki cloud and the meraki appliance itself ?

You seem to be running once per minute with an 800 second lookback from 'now', the only Nones that I see in your sample occur in the last record.

 

I'd guess the most recent data have not yet reached the cloud.

 

If you instead use a t0-t1 window that starts, say, 20 minutes ago and ends 5 minutes ago, do you still get the Nones?
