Used Disk in Solaris Agentd

[vanadaar]

I noticed when setting up a 'disk used' item in the front end the total for used disk is off from what solaris says the used space is. For example here is the line for a filesystem via CLI:

[root@solaris nameserve]# df -k /nameserve
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c0d1s0 10324476 344342 9876890 4% /nameserve

So it is currently using 326ish megs. However the agentd is reporting back this in the log:

8978:20081016:151053 Requested [vfs.fs.size[/nameserve,used]]
8978:20081016:151053 Sending back [440914]

which makes the front end say it is using 432 MB.

The item looks like:
vfs.fs.size[/nameserve,used]
unit: B
custom multiplier: 1024

Has anyone else experienced this? I just started evaluating zabbix, great software. Would like to cross this off as (my) human error.

free and total checks fine

the free and total checks come back exactly as they should. it appears just the free check does not.

vfs.fs.size[/nameserve,free] - responds as expected
vfs.fs.size[/nameserve,total] - responds as expected
vfs.fs.size[/nameserve,used]

Aix

the same code reports back used disk on AIX 5.2 properly. Going to test and see if compiling with the non-default gcc install on Solaris rectifies this problem.
