Like "8h 30m ago" I see, that I can create a widget showing me the LastCheckpointTime from JMX (in epoch format), but that number is not really intuitive to our Administrators. Even a conversion from epoch to human readable time would be awesome.</P><P>Thanks and best,</P><P>Benjamin</P> Wed, 04 May 2016 15:42:59 GMT https://community.cloudera.com/t5/Support-Questions/Ambari-Widget-for-time-since-last-HDFS-Checkpoint/m-p/130189#M92875 benhadoop 2016-05-04T15:42:59Z https://community.cloudera.com/t5/Support-Questions/Ambari-Widget-for-time-since-last-HDFS-Checkpoint/m-p/130190#M92876 <P>There's already an alert which monitors this for you.
