Re: [Hyperic-hq-discuss] StorNext file system I/O

[Doug M. <do...@hy...>]

Hi Chris,

DiskUsage.java is generated by the build system.  The code is actually in linux_sigar.c

The issue is likely file system -> device mapping:
% java -Dsigar.nativeLogging=true -jar sigar.jar iostat /
Filesystem      Mounted on           Reads     Writes R-bytes W-bytes Queue Svctm
0 [main] DEBUG Sigar  - [iodev] map / -> /dev/sda2
3 [main] DEBUG Sigar  - [iodev] map /boot -> /dev/sda1
3 [main] DEBUG Sigar  - [iodev] map /data -> /dev/sda5
3 [main] DEBUG Sigar  - /proc/diskstats / -> /dev/sda2 [8,2]
/dev/sda2       /                  1522729    3748132     10G     14G  0.96  3.66

The iostat command also accepts the device name, does this work for you?

% java -jar sigar.jar iostat sda
Filesystem      Mounted on           Reads     Writes R-bytes W-bytes Queue Svctm
sda             -                 26260315   15559442    433G    644G  0.97  3.66
