Symptoms
Transaction Analytics stops getting data even when all configuration is in place.
When the analytics-agent.log is checked, the following stacktrace could be captured:
[ERROR] [dw-15387 - POST /v2/sinks/bt] [c.a.a.p.http.AbstractPostReceiver] Request could not be processed as the input queue is full
...
[c.a.a.a.p.e.EventServicePublishStage] Transient error encountered due to the following cause: [Message could not be delivered because the REST resource rejected it]
com.appdynamics.analytics.shared.rest.exceptions.NotAcceptableRestException: For action [EVENT_UPSERT], you have reached the documents limit of [500000] for account [Account_name] and event type group [biz_txn_v.*]
at com.appdynamics.analytics.shared.rest.exceptions.RestExceptionFactory.makeException(RestExceptionFactory.java:47) ~[analytics-shared-rest.jar:na]
Once day limit is revised the data starts showing.
Diagnosis
This issue occurs because the number of transaction events reported in Transaction Analytics is more than 500,000 per unit (up to version 4.2.9) or 1,000,000 per unit (from version 4.2.9 and beyond).
The number of transactions is governed by your license, which sets the daily per-unit limit. Once the daily limit is reached, no further events will be stored.
Analytics License basis and entitlements by version

- Volume of data:
- Transaction Analytics: Measured as a specific number of Business Transaction events.
- Data retention time

Solution
That's the reason you see those consistent gaps which start showing data once the day limit is revised.
To resolve this you can get a license for higher unit limits, which will log higher number of events. You can also try reducing your events data.
