Solaris: email to user
Hi,

I would like to run cron job daily at 8:00 P.M in order to check the filesysem sizes , if if finds any filesystem space reaches to 90% it should me an email address to my outlook ( xxxxxx@abcd.com ) .

need your suggestion or direction how to achieve this.

Regards

Assuming you have are monitoring the /var filesystem on a Solaris system then you could use:
Code:
$ df -k /var
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/dsk/c0t0d0s3     138703    65426  59407    53%    /var
$

So to extract the value you could use:
Code:
$ df -k /var | grep /var$ | awk '{ print $5 }'

Which will extract the percentage full (the fifth item in the list) avoiding picking up the fifth item in the header line.

So in a script you would so:
Code:
PERCENTFULL=`df -k /var | grep /var$ | awk '{ print $5 }'`

You can then test for a value greater than 90% you can do:
Code:
if [ ${PERCENTFULL} -gt 90 ]; then
  send_an_email
fi

Sending an email depends on what you have on your system, on Solaris I would use mailx thus:
Code:
mailx -s "Subject heading" person@domain.com < inputfile

Where you have put what you want to send in the message in inputfile.

You would then call the resulting script from cron at 8pm every night:
Code:
0 20 * * * /usr/local/bin/yourscript.sh

HTH

Use the -v flag:

Code:
mailx -v -s test youraddress@domain.com
hello world
.

It will come out with a bunch of messages. If all goes well, check /var/log/mail.log

The part of the log that shows what mail server it is talking to would be helpful.

The MS Exchange server has to have SMTP enabled - you'll need to ask and Exchange expert about how to do that.

For Solaris 8 and below to make your Solaris machine use a particular machine as its mail server you can put an entry into its /etc/hosts file giving the IP address, name and then an alias of mailhost, this can be done in DNS using a MX (mail exchanger) record..

Looks like DNS is broken, presumably at the mrai.com end, but it is worth checking DNS is working at your end.
