Fill in the address with your email address, and you can also pipe an attac=
hment

For myself, I have scripts that detects when the service is down, sends me =
an email, then tries to restart it, then will email if it has managed to re=
cover it. If it can't restart it after 5 minutes, then I get an SMS.
In the morning, I can quickly see if it failed overnight, and my beauty res=
t only gets disturbed in the really bad cases.

How to detect down of tomcat.

Helo.

My environment is tomcat7, java1.6, windows.

When process of tomcat terminated abnormally,
is there any method or setting that output the abnormal termination to a lo=
g file?

If there is it, please let me know.

tomcat is the premise that is not service of windows, but even service is g=
ood.

The motive that wants to know such a thing is because I want to detect down=
 of tomcat in  automatically without human operation.
I set a file and keyword in a log monitor tool, and it  detects down of tom=
cat automatically.

Thanks for your advice.
