I used below line:df -H | grep d30 | awk ‘{print $5 ” ” $1}’ | main_prog

But it is not sending any email.

I need to run 2 gzips on differents directories but can’t run them at the same time since this will eat my cpu and the disk IO will be very high. I need to start one and then the other. Thanks in advance

Very urgent please

if [ ! "$usep" == "" ] ; then
if [ $usep -ge $ALERT ] ; then
echo “Running out of space \”$partition ($usep%)\” on server $(hostname), $(date)” | \
mail -s “Alert: $(hostname) almost out of disk space $usep%” $ADMIN
fi
fi

- it won’t work with non english output from df

change

    grep -vE "^Filesystem|tmpfs|cdrom"

to

    grep -vE "^Dateisystem|tmpfs|cdrom"

or you could change it to

  grep -vE "^[^/]|tmpfs|cdrom"

to remove all lines not starting with a / which would also remove mounted network shares (sshfs, nfs etc.)

additionally you could change the df command to

  df -hP fuse.sshfs -x nfs

to remove mounted network devices

another problem arises from the use of “sh” instead of bash –
it won’t work -
change the first line to

#!/bin/bash

to improve the error reporting you could also add the hostname to the subject line

mail -s "Alert: $(hostname) almost out of disk space $usep%" $ADMIN

after that i have user df -HP command to append it .. but iam not able to get the ouput through mail
#!/bin/bash

SENT_TO="dba-support@marlabs.com"
LOGFILE=/home/oracle/dba/scripts/log/disk_alert.log

Please help on this

thanks

the above scripts have been really helpful but can u give me a generalized way of extracting the necessary mount points in different servers. i am avoiding the way to hard code the mount point.

Thanks..

The syntax error “syntax error: “(” unexpected at “function main_prog() {”” can be solved by using bash instead of sh as script interpreter. So, after the shebang, use /bin/bash or /usr/bin/bash

does anyone has idea abt it please….it will be agreat assistance.

Best wishes,
Rajesh Thakur

All of them give errors….

What is wrong here?

Please help me?
Thank you very much

Best regards,

1) there is a filesystem with “$” (nfs mounted coming from windows hidden shares)

i.e //10.10.10.10/back$

2) the name of a filesystem is large and the percentage of use appears in another line

i.e.
//10.10.10.10/verylongnamefilesystem
78140128 45746488 32393640 59% /mnt/

Regards.
