Hi,

The right side of equal char which is attributeValue must be only numeric values.Probably your script contains string and you need to trim string chars.

Also the first “/” should be replaced, too. Here is sample blog for your reference. One of our community user; used below script for doing it.

script→ df -H | grep -vE ‘^Filesystem|tmpfs|media’ | awk ‘{ print $6"="$5}’ | sed ‘s/%//’ | sed ‘2s///ROOT/’ | sed ‘s///_/g’

I recommend filter the result set; it does not make sense to use every result for “df –h” . i.e. you /etc, /dev, proc, system… Only consider the mount points which relevant with WebLogic JVM processes.

Regards…
