[webmin-l] system and server status fillrate check

[Pat E. <mai...@pa...>]

hi jamie,

i use the the "Disk Space" monitor on all of my servers volumes, but when  
ist is most neccessary, it mostly fails. i talk about the case when an  
erroneous script is running amok and is filling up a volume; the alarm  
most of the time just comes to late.

in a recent sleepless night i came up with this cunning idea: ;)

measure the fill rate of a volume and than offer a failure state like:

in XX minutes available space is below XX percent/XX bytes


this way i could set up an alarm for sending a mail to sm...@ad... when  
the disk is really fast filling.

possible?

That's not a bad idea .. perhaps the monitor could set a fill rate
(say 1MB / second), and if disk space is being used up faster than that,
it would trigger.

Would that work in your case?

not really, because, when i have script running, that shuffles a lot of  
data around it shouldn't trigger, it should trigger, when 1mbit/sec is  
filled and there are only 600 mbit available (but this should be  
flexible). but if you know how much space is used up per minute you know  
how long the disk will float, so to speak..

A script that is just moving data wouldn't trigger the check I was thinking
of, as it isn't consuming any more disk space. I was thinking of a check 
on the rate that free space is being reduced..

that's right, i didn't phrase it correctly. i sometimes have job's, which  
create huge temp files - normally you can forsee, that the free space is  
large enough, but if not, an alarm triggered is what is needed..
