Allow to include/exclude Monolog logger channel on log forwarding

[tsantos84]

Summary

The PHP Agent allows to forward logs directly to NR servers but don't allow us to filter which log records we want to send, causing the sending of unwanted logs and impacting in the account billing.

Desired Behavior

Allow to developers to filter which logs records they want to forward to New Relic.

Possible Solution

Monolog \Monolog\Logger class has a mandatory constructor argument (eg. string $name) which tells the name of the logger instance and that argument will be passed as channel to LogRecord when $logger->log(...) is called. Frameworks like Symfony creates multiples instances of \Monolog\Logger each one having a diferente name/channel (eg. request, messenger, security, etc). The agent could use the channel property and allow us to filter which log record will be sent to NR servers.

Consider my application has 3 log channels:

$logger = new Logger('security');
$logger->info('Foo security message');

$logger = new Logger('doctrine');
$logger->info('Foo doctrine message');

$logger = new Logger('app');
$logger->info('Foo app message');

Now I want to send only app and doctrine channels to NR servers, I could configure the agent like this:

newrelic.application_logging.forwarding.monolog_channels_include=app,doctrine

Or

newrelic.application_logging.forwarding.monolog_channels_exclude=security

Additional context

I have undesired log records being sent to NR servers.

Hello,

It would be great to have the channel value in the metadata of the logs as well, to be able to query it.
Being able to do query on it would also allow to create drop filters based on this value
