HANAChecker

A monitoring script to automatically execute the SAP HANA's mini-checks and send alert emails

DESCRIPTION:

The HANAChecker executes SQL: "HANA_Configuration_MiniChecks" (See SAP Note 1969700 and SAP Note 1999993). For every "potential critical" mini-check, i.e. where the column C has an X, it sends out an email to the email address specified for that particular mini-check. This can run "forever" with a specified interval. See also SAP Note 1999993.

hanachecker's Issues

mailsend does not work

Hello Christian,

I just checkout hanachecker.py and test the function. However mailsend function does not work. So I just look into your code and I am wondering whether line 226 is commented out by mistake?
226 #subprocess.check_output(mailstring, shell=True)

I delete the # and mailsend is working.Would you please kindly check?

Thanks and best Regards,
Joseph Liu
