. /etc/profile ; rest of stuff perhaps.

If you schedule a command or pipe in cron, the resulting output will be mailed by default, no additional exercises necessary.

So, basically, you want to test, whether a number containing a decimal point is larger than 600?

If you are using Zsh as a shell, you have decimal arithmetic, and can simply compare the number you...

Not sure I understand. To monitor, you want that script to run all day, i.e. 24/7? In what intervals? Will iotop allow for that, do you want to loop inside your script, or do you plan to schedule a...

And where did you fail?

BTW, I don't see any DISK READ above 600MB in your sample?

If you have this as a value in $var, you could also:-echo $var | tr "()" "\n\n" | grep -E "^host="

It's a bit clunky, but might do the job you need.

Hello jaapar,

Could you please try following and let me know if this helps you.

awk '{match($0,/HOST=[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/);if(substr($0,RSTART,RLENGTH)){print...

If the only criterion were an IP address in dotted quad to follow the "HOST=" string, then RavinderSingh13's proposal would work fine, although it might be somewhat too cautious.
awk...

I can't confirm that "the exit code would always be 0" :
ssh root@"$server" "grep -q test log$(date +"%m%d")"; echo $?
0
ssh root@"$server" "grep -q txst log$(date +"%m%d")"; echo $?
1

Try ssh...

I guess the problem is in your invocation of ssh:
/usr/bin/ssh "$server" "cat log`date +"%m%d"` | grep test" >/dev/null 2>/dev/null
The | grep test should really be running on your machine rather...

You should be able to simplify that awk code a little bit to just:
20 * * * * df -h | tail +2 | awk '($5 + 0) > 98' | mailx -s "Email Subject" <email address>
but on a Solaris/SunOS system, that...

I think you can just set a cronjob to run at your preferred interval.

mine is running on solaris 10 hence command might varies.

20 * * * * df -h | tail +2 | awk '{if ((length($5) > 3) ||...

Almost certainly, yes. Look into the links at the lower left of this page, under "More UNIX and Linux Forum Topics You Might Find Helpful", or search these fora for "almost full".

The problem you may have is that the logical volumes in the volume group will probably be using it as their log volume. I'm not sure how it's still running if the disk blocks for the log volume are...

1. unmount /usr/local (I think this is the filesystem using loglv00 as logging device. In doubt you can try to find it using grep -p /dev/loglv00 /etc/filesystems).
2. remove loglv00
3. remove...

Just a minor addition: i'd call the ssh-facility this way to prevent problems in case keys are changed/deleted. Not allocating a terminal (-n) prevents problems when used inside pipelines:

Hi,

A script like this set up on ServerA should do the trick.


#!/bin/bash
date=`/bin/date +%Y%m%d%H%M%S`

email_to="unixforum@localhost"
email_subject="Something went wrong"...

This would work except for the missing separator line of the last record...paste -sd"\t\t\t\n" file1 | LC_ALL=C sort -k2,2gr | tr '\t' '\n'
user10 31.7 0.08 ...
