[Nagiosplug-devel] Update version of check_sap.sh

[Zöller, Benjamin]

Hi,
I updated the check_sap.sh skript.

Changes/Bugfix:
When sapinfo is missing or doesn't give any output the script gives an error back instead of ok.

Please check in into current svn.

Thank you!

Greetings,
Benjamin

#  $1 - type of checking - valid values: "ms" = message server
