Re: [milo-dev] eclipse milo - there are too many data updates from server
|
This behavior is something the server is responsible for. Whether that is correct or not probably depends on the sampling interval, queue size and DataChangeTrigger trigger you configured your items for.
Hello Milo-dev
We are using a milo client to connect to zenon server using UaSubscriptionManager:
subscriptionRef = client.getSubscriptionManager().createSubscription(1000).get();
Recently we noticed a strange situation when the server began to send us data updates too frequently (see logs excerpt below).
value received: item=NodeId{ns=2,
id=aaa},
value=Variant{value=33.97} at source time 2020-07-13 14:58:25.594 and
server time 2020-07-13 14:58:25.636
value received: item=NodeId{ns=2,
id=aaa},
value=Variant{value=33.97} at source time 2020-07-13 14:58:25.594 and
server time 2020-07-13 14:58:25.640
value received: item=NodeId{ns=2,
id=aaa},
value=Variant{value=33.97} at source time 2020-07-13 14:58:25.594 and
server time 2020-07-13 14:58:25.643
You may see that source time of data did not change at all and server time changes by matter of milliseconds (2 and later 3 milliseconds).
So right now we are puzzled by the possible reason behind these influx of data notifications: is it something that we can manage on client side or its purely on the server side.
