[jira] [Updated] (HDFS-8880) NameNode should periodically log metrics

     [ https://issues.apache.org/jira/browse/HDFS-8880?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Arpit Agarwal updated HDFS-8880:
--------------------------------
    Attachment: HDFS-8880.01.patch

Patch to log NameNode metrics once every 10 minutes by default to a separate _name-metrics.log_ appender.

The logging filters out {{TabularData}} and {{CompositeData}} metrics and also truncates string values at 128 bytes to avoid logging excessively.

Updated patch with tests to follow soon.

> The NameNode can periodically log metrics to help debugging when the cluster is not setup with another metrics monitoring scheme.
