I can't really think of anywhere else to put it, since the information is only required to be included in Notifications, and looking it up any earlier in the process (of raising a Notification) doesn't seem possible because we don't even know what the alerting host is until then. > > I can use things like $host.name$ and $host.display_name$ perfectly okay > > to get properties of the machine the notification is about. > > It's probably a problem of evaluation order, which is, to speak politely, > heavily under-documented, especially wrt. run-time macros. Yes, I've got as far as I have with the help of some example code in the online documentation, but I find the examples show how to do things which aren't really explained generically, and the relations between things like Host Objects and their (static or run-time) attributes, and the use of "macro", and how to pass parameters into functions, seems quite hard to understand. > I don't know a definitive answer, but I would try (combined with logging) Hm, logging, yes, that would be nice :) I've checked with "icinga2 feature list" that I have "mainlog" enabled. (If I turn on "debuglog" there is so much continuous output that I can't see what I'm looking for when I make something happen.) https://icinga.com/docs/icinga2/latest/doc/14-features/ tells me that: "mainlog - Main log (path: /var/log/icinga2/icinga2.log, severity: information or higher)" https://icinga.com/docs/icinga2/latest/doc/18-library-reference/#log tells me: "function log(severity, facility, value) Writes a message to the log. severity can be one of LogDebug, LogNotice, LogInformation, LogWarning, and LogCritical." So, what am I supposed to put into a log() call in my code to get whatever's being logged to appear in /var/log/icinga2/icinga2.log ? "severity" is clearly "LogInformation" or higher (and I'm assuming that LogDebug is the lowest priority, LogCritical is the highest?) But what's "facility"? I'm familiar with that for syslog-style logging, but what should I use here? I don't see that mentioned anywhere in the log() function notes :( > -- get_host(macro("$host.vars.neighbour$")) > -- call a function (declared with parameter x) on "$host.vars.neighbour$" > or macro() that returns get_host(x).whatever Yep, I'm fiddling with various variations on those themes... > Even better, someone could speak up who really knows. Nice idea :) Volunteers, anyone?
