I use nagios to monitor about 30-50 servers. It is pretty good, but it can take a while to get its dependency tree right. There is no UI to configure it. You have to edit all the config files manually, and there are A LOT! It has a plugin architecture based on calling out to another process. This works out ok, and I've even used it to monitor custom applications. It can also be peered to solve the "who's monitoring the monitor" problem. The unfortunate part is I now have to carry a cell and I get SMS messages when something horrible happens. It is really a cost vs time and skill question. If you have more Unix admin skills and time than money it is a reasonable choice. -- Christopher Baus http://www.baus.net/ Tahoe, Wine, and Linux. _______________________________________________ RLUG mailing list [EMAIL PROTECTED] http://lists.rlug.org/mailman/listinfo/rlug
