----------------------------------
Summary: Add the *FirstMessage* API for scheduled messages
Key: ARTEMIS-4579
URL: https://issues.apache.org/jira/browse/ARTEMIS-4579
Project: ActiveMQ Artemis
Issue Type: Improvement
Components: API
Affects Versions: 2.31.2
Reporter: Jan Šmucr
Fix For: 2.32.0
Alerting on issues with messages not being received properly for a period of
time is an uneasy task. We use the {{getFirstMessageAge()}} command to trigger
alerts in Zabbix, and it works as long as there are no consumers.
But this approach fails when there are consumers repeatedly failing to receive
a message. That message is getting scheduled for redelivery over and over, and
even though there still is an old message in the queue to be reported, it's no
longer visible via {{getFirstMessage*()}} API.
The goal here is to add a set of functions working with messages scheduled for
delivery:
{noformat}
getFirstScheduledMessageAsJSON()
getFirstScheduledMessageTimestamp()
getFirstScheduledMessageAge()
{noformat}
It may be not the most effective approach but it's quite a convenient one,
especially when monitoring a wide set of queues, each with its own set of
alerts.
