[Setup] best practices for restarting instances

[Christian Ledermann]

I use supervisor + memmon + httpok

in the supervisord.conf it looks like:

[program:plone_sites1_client1]
command=/home/user/webapps/plone_sites1/zeocluster/bin/client1 console
priority=104

[eventlistener:memmon_sites1]
command=memmon -p plone_sites1_client1=1GB
events=TICK_60

and httpok to check if the instance is responding:

[eventlistener:httpok_sites1]
command=httpok -p plone_sites1_client1 http://localhost:8080/
events=TICK_60

If you save the living environment, the biodiversity that we have left,
you will also automatically save the physical environment, too. But If
you only save the physical environment, you will ultimately lose both.

1) Don’t drive species to extinction

2) Don’t destroy a habitat that species rely on.

3) Don’t change the climate in ways that will result in the above.
