----------------------------------
Summary: Change in JMX names (OAK-3477) breaks discovery.oak's
SynchronizedClocksHealthCheck
Key: SLING-5480
URL: https://issues.apache.org/jira/browse/SLING-5480
Project: Sling
Issue Type: Bug
Components: Extensions
Affects Versions: Discovery Oak 1.2.4
Reporter: Stefan Egli
Assignee: Stefan Egli
Fix For: Discovery Oak 1.2.6
OAK-3477 changed the naming convention of JMX Mbeans created by oak. Originally
the DocumentNodeStore was created as follows:
{noformat}
domain/type/name/properties
org.apache.jackrabbit.oak "DocumentNodeStore" "Document node store
management" {id=6}
{noformat}
while OAK-3477 changed that to:
{noformat}
domain/type/name/properties
org.apache.jackrabbit.oak DocumentNodeStore Document node store
management
{noformat}
(meaning, the type is not quoted anymore, plus the id is gone)
This breaks the query used in {{SynchronizedClocksHealthCheck}} to get the
{{DocumentNodeStoreMBean}} (fyi [~chetanm]). Currently this results in the
health check to report that: "Intra-cluster test n/a (No DocumentNodeStore
MBean found) " - ie it goes rather unnoticed and effectively the health-check
is disabled. So we need to adjust the query in SynchronizedClocksHealthCheck.
