> The SecondaryNameNode status.jsp page contains the following:
> {noformat}
> SecondaryNameNode Status
> Name Node Address    : snn1/172.29.122.91:50020
> Start Time           : Fri Nov 09 09:25:29 PST 2012
> Last Checkpoint Time : Thu Nov 15 15:35:06 PST 2012
> Checkpoint Period    : 30 seconds
> Checkpoint Size      : 39.06 KB (= 40000 bytes)
> Checkpoint Dirs      : [file:///tmp/hdfs-adi/dfs/namesecondary]
> Checkpoint Edits Dirs: [file:///tmp/hdfs-adi/dfs/namesecondary]
> {noformat}
> The JMX page at {{:50090/jmx}} should also provide this info; at the very least the Last
Checkpoint Time and Checkpoint Size so that users are not tempted to scrape the {{status.jsp}}
output.  Perhaps I'm missing it but these data seem to be missing.
