how do I get lsof information??
I tried to use the lsof command and it didn't work. (trying to get a list of open files on the system)
How do I get this information?
What happened to me today was that our machine was in the weeds ... just being really sluggish. So I ran top and found that tar was taking up 25% of the CPU ... not a good thing.
first thing I tried was lsof ... but that doesn't appear to work in for an container Accelerator.
so I killed the offending tar process ... still wondering what it was trying to do. We run a couple of cron jobs to rotate logs, do backups, etc. I did search for huge files but didn't find anything ...
any thoughts or suggestions on how to debug this situation would be greatly appreciated ... hoping that there isn't going to be one ... yea right ...

Re: how do I get lsof information??
May not be installed. It's not included in the distribution.
Maybe you can use fuser? Need to be logged on as root to run fuser though.

Re: how do I get lsof information??
it is there ... but not there
Code:
[z0002:/var/log] root# lsof
lsof: can't stat(/devices): No such file or directory
thanks will look into fuser

Re: how do I get lsof information??
looked at fuser and it appears to give a list of processes which have open files. In my case I knew it was pid 1000 (I got that from top) But I don't see a way to get the list of open files for a specific process. Am I missing something here??

Yes, that is what I was looking for. Thanks

awwww don't be so hard on it ... it would have answered my question of if/which cron job had gone nuts.
There is another function which used to use alot and I am unable to recall the name. It also takes a pid and then prints out all of the system calls as they happen. (Still brushing off the dust ... it's been a while since I used solaris ... back when sparc ultra 1 seemed really, really fast ... )

Have a look at Ben's introduction to Solaris .. you'll probably be wanting one of vmstat, mpstat, pstack or dtrace.
Take a good look at dtrace in particular. I'm told it's teh hotness.

Re: how do I get lsof information??
Glad you got what you needed! Seeing as I actually have no access to Solaris (nor have I ever), I'm glad Ryan was around to give you advice!

Re: how do I get lsof information??
I hit the same problem (trying to use lsof and getting that error message). I'm now reading through the articles mentioned above :). Just to note, it looks like the problem with lsof is that it can't be run from within a solaris zone.
