You've almost got to this solution but say "and couldn't just ". Not sure why you say that but I'll briefly cover what I did. You will need some programming/scripting. First up in the nagios.cfg file configure either a specific configuration file or directory where you will define your dynamic service checks eg cfg_dir=/etc/nagios/dynamic_services or cfg_file=/etc/nagios/dynamic_services.cfg Using a file/directory will be dependent on exactly how you need to generate your checks. Then at the point where you know what the service checks will be generate the appropriate nagios config file based on what is in the database into either your single config file or into one file each in the dynamic directory. You will then need to reload the nagios config and make sure it syntaxes ok. We do this quite sucessfully. When customers add/delete servers we just regenerate the config to match and reload Nagios.

For each tag we have a process that generates a Javascript file and pushes it out to a CDN. I've successfully created a service check to monitor that the process runs successfully (by using check_mysql_query to verify that a "pushed" date gets updated on the database table). But we also need to monitor that each of the files exists - and in the correct version - over at the CDN, and here's where I'm hitting a wall. What I'm envisioning is a way whereby I could dynamically generate a whole bunch of service checks - one for each tag in the database table. Each service check would then go and download its corresponding file from the CDN, parse it, and verify the version number. In this way, if any particular file was missing or the wrong version, we would get a Nagios alert on that tag/file. However, I don't see any clear way to approach this with Nagios. Near as I can tell there doesn't seem to be any way to dynamically generate service checks. From my reading of the docs, every service need to be explicitly listed in the config files beforehand. I was thinking that perhaps having a cron job that generates passive checks might be a solution here, but again it looks like I would still need to have the service checks defined beforehand in the nagios config files, and couldn't just generate them on-the-fly based on the contents of the database table. Anyone have any ideas on how I could accomplish this file monitoring in a dynamic fashion? (Note that alerting on a file-by-file basis is needed here; it would not be sufficient to have a single service check that monitors and alerts on all of the files.)
