Napp-it iostat_60s.log = 220meg

[Bob T Penguin]

Hello, Ive been reading this forum for many months, and now it's time to ask my first question.
I've got an Omnios box with Napp-it Pro installed and running. I've noticed prstat was showing a perl script using 10% CPU usage so I did some investigating and found it was:
/var/web-gui/data/napp-it/zfsos/_lib/illumos/agent_stat.pl

That script was writting to /tmp/iostat_60s.log and had created a 220meg file. Here is an extract from the file:

(Sorry for not knowing how to format that properly)
Virtually the whole file is full of references to 192.168.1.4:/mnt/storage. WHY?

this location is an old freenas box I use for backups. My back up script uses rsync to copy files to 192.168.1.4:/mnt/storage. Why is napp-it filling iostat_60s.log with references to this location?

Thanks
Bob

Edit...
Sorry, should have mentioned. My back up script is triggered by cron at 09:12, 15:12, 21:12.
here is a line from the script:
rsync -avz --delete /tank/tempstorage/music/ /net/192.168.1.4/mnt/storage/MusicJukebox/

Thanks Bob

This is a logfile that is base of the realtime graphs (last minute activity).
You can disable realtime logging in the upper right top menu of napp-it when you click on "Mon"

 

[Bob T Penguin]

@gea, Thank you. I've disabled realtime monitoring and the perl script I mented above seems to have stopped.

Why was the real time monitor scanning an NFS share on my network?

Thanks
Bob

 

[gea]

Its logging disk/iostat activity

 

[Bob T Penguin]

oh, ok. But this is a folder that's accessed over an NFS network share, it's not physically attached to my Omnios box. Is it possible to modify /var/web-gui/data/napp-it/zfsos/_lib/illumos/agent_stat.pl so that it only gathers data for disks that are physically attached to the local computer?

I guess I'm showing my noobie-ness...sorry about that.

Bob.

 

[gea]

There are logs about disks, pools, protocols (ex NFS), filesystems, nics.
see menu Extensions > Realtimemonitor

I would suggest to deactivate them all when not needed

 

[Bob T Penguin]

Thank you Gea. I was hoping you'd be able to explain why napp-it is recording data about my NFS shares, "switch it off" doesn't really explain what's going on. Anyway, it's not important, just weird. regards, Bob.

 

[gea]

The last minute log is mainly based on:
iostat -xcn 1

Does this show your NFS mounts?

 

[Bob T Penguin]

I access the NFS share via the automount folder /net/.
If I've NOT accessed the NFS share (it's not mounted under /net/192.168.1.4/mnt/storage) it does NOT show up in isostat -xcn 1 output.
If I HAVE accessed the NFS share (so that it is mounted under /net/192.168.1.4/mnt/storage) then it does show up in isostat -xcn 1 output.

 

[gea]

ok, seems easy to remove lines with an / as they are not disks but mounts.
Will include that in next release.

 

[Bob T Penguin]

oh, cool! Thanks. Regards Bob.

 

[gea]

You can try the following

modify line 282 of to /var/web-gui/data/napp-it/zfsos/_lib/illumos/agent_stat.pl (add the | grep -v /)
open (T,"-|","iostat -xcn 1 | grep -v /");

 

[Bob T Penguin]

@gea, just saw your post. I've updated the file and things seems OK.
iostat -xcn 1 reports 192.168.1.4:/mnt/storage but it's not showing up in iostat_60s.log (and the file is remaining about 4k).
Thanks, Bob.
