Hi, Is there a tutorial on exceptions and error management in puppet script ? I read the manual and found information which is confusing for me. There is the notify function which seems to be executed on agent. There are functions like notice, alert, fail and so on which are executed on server. And I read the ErrorLog word. So how to put all things together, what is the right policy ?

Notify is not a function. It is a resource type. It essentially logs on the client by putting a message in the client''s catalog. alert, crit, debug, emerg, err, info, notice and warning are functions. They will record a message to the server''s log at the specified level. Parsing and execution will continue. I did not list the levels in any particular order. fail is also a function. It is a way to programatically cause a parse failure. The error will be logged and execution on the current node will stop. I''m not sure what you mean about ErrorLog. Where did you see it?

RE: [Puppet Users] Re: exceptions, error, traces
Hi, First, thanks for your answer. I am not still aware of a deep understanding of differences between resources and functions, but some tests confirmed what you said. A point, with my tests, notify messages are displayed in the reverse order they are written in manifest ... I understood that alert, crit, debug, emerg, err, info, notice are functions executed on server during parsing step; the documentation explains that, by default, messages are sent to syslog even if I did not find them. Thanks for your details on fail function, I did not understand clearly which effects this function has. I found ErrorLog in learning puppet documentation, (Generated on October 24, 2012, from git revision 38e9e6c36310cb4895f51e180890cd3fbbbba28e) page 53/67 : this is a sample of an erb file.
