Subject [jira] [Commented] (SOLR-2698) Enhance CoreAdmin STATUS command to return index size
Date Thu, 04 Aug 2011 15:45:27 GMT

    [ https://issues.apache.org/jira/browse/SOLR-2698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13079428#comment-13079428

Yury Kats commented on SOLR-2698:
---------------------------------

FileUtils.byteCountToDisplaySize could produce a different result than what's being returned
now.

http://www.discursive.com/books/cjcook/reference/io-network-sect-printing-human-readable mentions:

  FileUtils.byteCountToDisplaySize( ) will not round the size of a file; a 2.9 MB file will
have a display size of 2 MB. 

If that's true, it's not very useful.

We could go a step further and return index size in bytes AND as a readable string in the
response.
If need to choose one or the other, my preference would be for just bytes (long). If it's
a String, any application processing the response will need to convert it into bytes anyway
to do any meaningful analysis.

> CoreAdmin STATUS command returns all kinds of index info for all cores on the server,
except for the index size.
> However, indexSize can be retrieved for an individual core via a /replication&command=details
request.
> I have N Solrs servers, running M cores each. My application is monitoring the status
of all cores, including their index size.
> As it stands today, I need to issue N status requests plus N*M replication requests to
get all the information I need.
> If STATUS command returned indexSize, number of requests would be just N.
