Hy there,
we are logging data losses for some test nodes. Over the last days we had increased loss rates. The following log was written within node-red, it gives the node packet counter, the time since last reception and a time stamp:
{"arduino_test":10377,"arduino_test_delta":2463.921,"timestamp":"2019-10-22 14:13:19","arduino_test_lost":40}
{"arduino_test":10416,"arduino_test_delta":2336.506,"timestamp":"2019-10-22 14:52:16","arduino_test_lost":38}
{"arduino_test":10427,"arduino_test_delta":664.953,"timestamp":"2019-10-22 15:03:20","arduino_test_lost":10}
{"arduino_test":10428,"arduino_test_delta":57.415,"timestamp":"2019-10-22 15:04:18"}
{"arduino_test":10454,"arduino_test_delta":1557.818,"timestamp":"2019-10-22 15:30:16","arduino_test_lost":25}
{"arduino_test":10496,"arduino_test_delta":2519.84,"timestamp":"2019-10-22 16:12:16","arduino_test_lost":41}
Checking the gateway logs I found, that during the ādowntimeā lotĀ“s of data have been sent:

So, it lookis like data have been transmitted, but do not reflect in the backend. We are usint ttn-contrib-nod-red to receive data in node-red.
I know there is a status page, but this gives us only current status. Is there any status history to see, if data losses are caused by downtime or maintenance?
