Hi advisors ,
I would some suggestions on using http://cr.yp.to/daemontools.html .
My requirements is to use less systems daemon checks in nagios but concentrate more on business / application level checks .
We have lots of daemons like below
- ) snmpd
2.) ntp 3.) SSH 4.) crond 5.) php-cgi 6.) nginx 7.) Postfix 8.) wackamole 9.) spread 10.) atop 11.) redis 12.) taillog-dopa 13.) taillog-user 14.) rsyncd
... ETC.
We use nagios checks + event-handlers in case of daemon failure .
My views is to use daemontool to control all these daemons , and create a single nagios check which scans /service/ directory and alerts for daemons which are getting restarting in unwanted ways.
Some of my friends will argue about daemontools being non-unixy and unconventional , But I had good experience with daemontools on around 3000 servers earlier in my previous organization .
Please advice what you guys think about daemontools and its pros and crons .
Thanks , Saurabh Verma
