KDB and filemon.

[Casey J Brotherton]

Hi,
We have a system with a high utilization of one of the disks.
We ran filemon and was able to generate some information about
files that have been used on the disk. It has been
run after an application has been started, so not all of the files
have filesystem:inodes associated with them.

I know in kdb, you can look at a process and see what file descriptors
are open, but in the filemon output, there is a reference to
file descriptors for process 0. I looked, there are no file descriptors
associated with that process slot. anyone have an idea where those
descriptors are stored? Or is filemon broken?


Thanks,

Casey.

From filemon output:

Most Active Files
------------------------------------------------------------------------
#MBs #opns #rds #wrs file volume:inode
------------------------------------------------------------------------
143.3 0 5089 5 pid=0_fd=16484
45.4 0 3737 1803 pid=0_fd=29930


from kdb at bottom of output for (0)>> proc 0

File descriptor table at..2FF3CEE0:
Rest of File Descriptor Table empty or paged out.

64-bit process context [2FF7D000]: unused
