Good day!

Guys, I need your help again.
Is there someone here who have guidelines for setting up the alarm level for 
disk usage?
It's just that I can't defend it if I'm just going to set something without 
reference.

Please kindly share it to me. I just need it so badly.

Thank you very much!

I probably depends on how fast the disk fills up and how quickly you can
respond to clean it.

Our "default" levels are 500Mg warning, and 100Mg red.  On some other
systems that have web servers that we want to be alarmed sooner, we have
the warning at 1g, while the alarm is 500Mg.

We've been looking at changing some of the Oracle servers we have to
higher than 500/100 since when someone is processing a giant load the
archive logs can fill the disk up way to fast.

On a system that uses disk based backups, the level are even much
higher, around 100g warning, and 70g alarm.

It'll all depend on the individual system and how fast you can respond
when a warning/alarm notification goes out.

Hi.

I don't have any guidelines, except of course to look in the configure files for each client.

If you're going to configure a windows machine (BBWin) then I suggest changing the xml file located (most often anyways) in c:/program files/bbwin/etc/ and change the value from which the alert comes. I don't remember what the line says, but its under a subclass of <disk> or something like that.

As for configuring Linux clients, change ~hobbit/client/etc/localclient.cfg file. It should include instructions on how you can alter the defaults for that machine.

With regards,

Thanks Eric,

Base on what you said, I added some points to consider and here it is:

Guidelines in setting up disk monitoring alarm levels:

1. How fast the disk fills up?
        a. Temporary disk usage
        b. Regular disk usage increase (Monthly, Weekly)
2. How fast you can respond whena warning/alarm nitification goes out?
        a. During the alarm, make sure that the remaining disk space can 
maintain system availability while addressing the problem.
        b. Identify what files to move/delete - this is to speed up the 
recovery

Can you please further eloborate if I miss other factors cause I think I 
still do.
Maybe other menbers can also add their ideas so we can make a more effective 
guidlines for disk monitoring.
I think this is very helpful specially to those that do not have a lot of 
experience like me.

Thanks and regards,
Ryan

Hi all, 

It is already mentioned in the discussion one of the most interesting things in disk monitoring is 
How fast the disk fills up. 

It would be nice to be able to monitor a sudden grow of used disk space. 

Regards,

One other item I did touch on would be the purpose of the disk.  For
example disk based backups you might want at higher levels just to catch
something before the night when all backups normally occur.  This does
go along the same lines as 1 & 2, but adds a little different thought
into planning the levels.
