NAME

FS::Log - Freeside event log

SYNOPSIS

use FS::Log;

sub do_something { my $log = FS::Log->new('do_something'); # set log context to 'do_something'

 ...
 if ( $error ) {
   $log->error('something is wrong: '.$error);
   return $error;
 }
 # at this scope exit, do_something is removed from context

}

DESCRIPTION

FS::Log provides an interface for logging errors and profiling information to the database. FS::Log inherits from Log::Dispatch.

CLASS METHODS

new CONTEXT

Constructs and returns a log handle. CONTEXT must be a known context tag indicating what activity is going on, such as the name of the function or script that is executing.

Log context is a stack, and each element is removed from the stack when it goes out of scope. So don't keep log handles in persistent places (i.e. package variables or class-scoped lexicals).

context

Returns the current context stack.

log LEVEL, MESSAGE[, OPTIONS ]

Like Log::Dispatch::log, but OPTIONS may include:

- agentnum - object (an <FS::Record> object to reference in this log message) - tablename and tablenum (an alternate way of specifying 'object')
