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')
POD ERRORS
