+1 on using Nagios or a similar tool they are made to monitor, so let them do what they are made for. Personally, I prefer that approach. If you plan to grow to any size, having a real monitoring system like nagios around will be essential anyhow. It will give you more than just this one check, and provide better escalation, alerting, and trending. Figure it out early, and get it integrated with your installs. To scale, you¹ll want each host to run a series of local checks, and submit back to the primary monitoring cluster with nsca (no clunky SSH checks)... The local client code can/should still be distributed and managed by cfengine. Of course remember... A shell script or policy that emails you now can hold you over until Nagios is ready for deployment. "Don't let best be the enemy of good," and all that. Good luck! _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
