Hello, I'd like to know the best way to collect new/incoming Fact values for a node and compare it to old/previous values (i.e. from a node making a puppet run). My thinking is that the new values need to be intercepted before they are stuffed into PuppetDB (or /var/lib/puppet/yaml/facts/<node>.yaml), but I don't know where the appropriate place for that would be. I'm thinking the options -- all of which may not work -- are:
1. In Puppetmaster code somewhere, i.e. before it sends it to the Fact storage backend. 2. In PuppetDB code, i.e. the function "Replace facts", before the new facts get stuffed into the database. 3. In a custom server function I like Option 3 the best since it is simple and does not involve hunting around in the Puppet code base, but it also seems like it won't work: wouldn't the 'lookupvar' function commonly used in server functions retrieve the new Fact value that just got stored from the in-progress Puppet run? By the way, I'm wanting to build a monitoring tool around Facter that provides email alerts (and maybe a fancy web frontend for alerts/events) when certain user-definable fact value changes occur. If there's already a good tool out there that does this, I might be saved a bit of work. :) Thanks, Kent -- You received this message because you are subscribed to the Google Groups "Puppet Developers" group.
