Subject: Add data cache statistics to nfs-iostat.py
Date: Mon, 20 Apr 2009 19:03:32 -0700 [thread overview]
Message-ID: <1240279414-30528-1-git-send-email-kevin.constantine@disneyanimation.com> (raw)
The first patch adds a --data flag, and prints a line about data being read by NFS
Data Read: From Server From Cache Total Hit %
5676.7534MB 1862.0452MB 7538.7987MB 24.70%
The second patch adds a line about write data. I'm not quire sure about this patch. I'm seeing oddities where the number of bytes in "NORMALWRITTENBYTES + DIRECTWRITTENBYTES" does not equal SERVERWRITTENBYTES. In some cases the amount of data written by the app (normalwrittenbytes + directwrittenbytes) is greater than the amount of data written to the server, and in other cases it's less than the amount of data written to the server. At the moment, i've ascribed that difference to data being written to the local cache and not flushed, but that doesn't make a whole lot of sense.
Data Written: To Server To Cache Total
5.2221MB 0.1951MB 5.4172MB
