How can the DevOps engineer obtain more information about the root cause of this issue?

  • A Increase the logging level for the health reports in the maintenance UI.
  • B Increase the logging level for org.apache.jackrabbit.oak.plugins.index.
  • C Increase the logging level for stdout.log to DEBUG in the sling log support configuration.
  • D Increase the logging level for stderr.log to DEBUG by setting a JVM option.
Explanation

Oak’s asynchronous indexer can lag or fail, leaving LastIndexedTime unchanged and causing recently published content to be absent from search results. Increasing logging for org.apache.jackrabbit.oak.plugins.index produces diagnostic output from the relevant index-update and asynchronous-indexing components. The Oak Indexing documentation identifies LastIndexedTime as the time through which repository state has been indexed and exposes it through the async indexer’s IndexStatsMBean.
