Log::Handler::Levels(3pm) User Contributed Perl Documentation Log::Handler::Levels(3pm) NAME
Log::Handler::Levels - All levels for Log::Handler. DESCRIPTION
Base class for Log::Handler. Just for internal usage and documentation. METHODS
Default log level debug() info() notice() warning(), warn() error(), err() critical(), crit() alert() emergency(), emerg() Checking for active levels is_debug() is_info() is_notice() is_warning(), is_warn() is_error(), is_err() is_critical(), is_crit() is_alert() is_emergency(), is_emerg() Special level fatal() Alternative for the levels "critical" - "emergency". is_fatal() Check if one of the levels "critical" - "emergency" is active. Special methods trace() This method is very useful if you want to add a full backtrace to your message. Maybe you want to intercept unexpected errors and want to know who called "die()". $SIG{__DIE__} = sub { $log->trace(emergency => @_) }; By default the backtrace is logged as level "debug". # would log with the level debug $log->trace('who called who'); If you want to log with another level then you can pass the level as first argument: $log->trace(info => $message); dump() If you want to dump something then you can use "dump()". The default level is "debug". my %hash = (foo => 1, bar => 2); $log->dump(\%hash); If you want to log with another level then you can pass the level as first argument: $log->dump($level => \%hash); die() This method logs the message to the output and then call "Carp::croak()" with the level "emergency" by default. $log->die('an emergency error here'); If you want to log with another level, then you can pass the level as first argument: $log->die(fatal => 'an emergency error here'); log() With this method it's possible to log messages with the log level as first argument: $log->log(info => 'an info message'); Is the same like $log->info('an info message'); and $log->log('an info message'); If you log without a level then the default level is "info".

Log::Handler::Output::Email(3pm) User Contributed Perl Documentation Log::Handler::Output::Email(3pm) NAME
Log::Handler::Output::Email - Log messages as email (via Net::SMTP). SYNOPSIS
use Log::Handler::Output::Email; my $email = Log::Handler::Output::Email->new( host => "mx.bar.example", hello => "EHLO my.domain.example", timeout => 120, debug => 0, from => 'bar@foo.example', to => 'foo@bar.example', subject => "your subject", buffer => 0 ); $email->log(message => $message); DESCRIPTION
With this output module it's possible to log messages via email and it used Net::SMTP to do it. The date for the email is generated with "Email::Date::format_date". Net::SMTP is from Graham Barr and it does it's job very well. METHODS
new() Call "new()" to create a new Log::Handler::Output::Email object. The following opts are possible: host With this option you has to define the SMTP host to connect to. host => "mx.host.com" # or host => [ "mx.host.example", "mx.host-backup.example" ] hello Identify yourself with a HELO. The default is set to "EHLO BELO". timeout With this option you can set the maximum time in seconds to wait for a response from the SMTP server. The default is set to 120 seconds. from The sender address (MAIL FROM). to The receipient address (RCPT TO). Additional options are cc and bcc. subject The subject of the mail. The default subject is "Log message from $progname". buffer This opts exists only for security. The thing is that it would be very bad if something wents wrong in your program and hundreds of mails would be send. For this reason you can set a buffer to take care. With the buffer you can set the maximum size of the buffer in lines. If you set buffer => 10 then 10 messages would be buffered. Set "buffer" to 0 if you want to disable the buffer. The default buffer size is set to 20. debug With this option it's possible to enable debugging. The information can be intercepted with $SIG{__WARN__}. log() Call "log()" if you want to log a message as email. If you set a buffer size then the message will be pushed into the buffer first. Example: $email->log(message => "this message will be mailed"); If you pass the level then its placed into the subject: $email->log(message => "foo", level => "INFO"); $email->log(message => "bar", level => "ERROR"); $email->log(message => "baz", level => "DEBUG"); The lowest level is used: Subject: ERROR: ... You can pass the level with "Log::Handler" by setting message_pattern => '%L' flush() Call "flush()" if you want to flush the buffered lines. sendmail() Call "sendmail()" if you want to send an email. The difference to "log()" is that the message won't be buffered. validate() Validate a configuration. reload() Reload with a new configuration. errstr() This function returns the last error message. DESTROY
"DESTROY" is defined and called "flush()". PREREQUISITES
