Gluster.org Gerrit 21753 0 None Merged debug/io-stats: Fix json output 2018-12-05 15:04:56 UTC

Description Chris Holcombe 2018-11-29 00:40:14 UTC
Description of problem: The json output of the io-stats debug xlator quotes the numbers as strings instead of just printing them as numbers.  This makes parsing them in a strongly typed language more difficult than it should be.  This is an easy fix so I'll be following up with a patch to correct the output.  

Version-Release number of selected component (if applicable):
As far as I know it's been like this since first released.  Commit: d3e496cbcd35b9d9b840e328ae109c44f59083ce and bug id: 1271310

How reproducible: Easily reproducible by enabling the iostats fop diagnostics.  

Steps to Reproduce:
1. Setup a gluster volume called gv0
2. gluster vol set gv0 diagnostics.dump-fd-stats on
3. gluster vol set gv0 diagnostics.count-fop-hits on
4. gluster vol set gv0 diagnostics.stats-dump-interval 10
5. gluster vol set gv0 diagnostics.fop-sample-interval 10
6. Observe output in /var/lib/glusterd/stats/xxx.dump files

Actual results:
Json entries look like this:
"gluster.brick._mnt_brick.inter.bytes_written_per_sec": "0.00"

Expected results:
Json entries should look like this:
"gluster.brick._mnt_brick.inter.bytes_written_per_sec": 0.00
