Subject [jira] [Commented] (HADOOP-12823) Collect disks usage on the node in Windows
Date Thu, 18 Feb 2016 23:26:18 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15153333#comment-15153333

Inigo Goiri commented on HADOOP-12823:

The proposal is to extend winutils/systeminfo.c to collect disk usage using PDH.
The performance counter to collect will be the summation of \LogicalDisk(_Total)\Disk Write
Bytes/sec and \LogicalDisk(_Total)\\Disk Read Bytes/sec.
I think that HADOOP-12211 uses this rate value; otherwise, we will have to figure some other
performance counter.
