DISCUSSION: Monitoring Harddrive usage automatically

This thread is to discuss the article titled: Monitoring Harddrive usage automatically

Hope you don't mind my editing too much :)
I corrected a few flaws in your cron explanation
and changed grep to egrep and made it match
100 as well.

just a note on the first part of the cron entry:
the * means: run every possible time for this field.

i.e. 5 22 * * * means minute 5, hour 22, and then every day of the month, every month, and every day of the week.
If you added 5 22 15 * * the cron would only run on the 15th day of the month.

But then his tutorial isn't on cron, it's on automated
disk-space monitoring... ;)

I've been to a demo of a very impressive Monitoring solution by MetaMind in Basel. It's very efficient since even when everything fails, agents (they call metamon) continue to trace why this happened and will fill logs as soon as back online...

Worth a check at: www.metamindsolutions.com

Wonder where that logs to when both hdd's and a
network-connections are gone :)

Btw, the homepage is atrocious.

Nice as a whole. Being me and thus being lazy, I'd want to know in the mail which drive was how full without having to run the job again on my screen.

My first idea was to "tee" the second pipe and by that means insert the egrep-results into the mail. Could this be done by variables as well and how would they get their values assigned and introduced into the mail?

Nichts leichter als das :}
[Nothing more easy than that :}]

0 22 * * * full=`df | egrep "(100%|[89][09]%)"` && mail -s "Warning, $full is filling up."  you@emailaddr.com

Wirsing,
Tink

Guten Morgen
[good morning ... ahm, should rather be good night in NZ]

Whoa, we are on the economic trip here .
Thank you for the solution.

Wirsing? Grütze an die Kiwis!

I take it you liked my solution? :)


One is glad to be of service ...

Und Danke fuer die Gruetze ;}

I sort have made my own rendition of this script. I only have it monitoring one volume though.

FS=/dev/hd2
USAGE=`df | grep $FS | awk '{ print $4 }' | sed "s/%//"`
PERCENT=90

if [ $USAGE -gt $PERCENT ]
        then
                echo $FS Filesystem on $HOSTNAME has reached "$PERCENT"% capacity | mail -s $HOSTNAME kristijan@fake.com
fi

Seems to do the job

This is neat! (We get emails like this over the main mailing list my office uses, and I've always wondered how they were doing it... )

Cheers

Here is a thread in which a monitoring with gnuplot and the S.M.A.R.T. suite is explained:
