Log reader
Allow you to parse symfony and apache access logs.
BEWARE, it can take a lot of time depending on the amount of data (For a typical symfony dev.log it starts to really slow down after 10k lines)
Installation
composer require innmind/log-readerUsage
use Innmind\LogReader\{
Reader,
LineParser\Monolog,
Log,
};
use Innmind\OperatingSystem\Factory;
use Innmind\Filesystem\Name;
use Innmind\Url\Path;
use Psr\Log\LogLevel;
$os = Factory::build();
$read = Reader::of(
Monolog::of($os->clock()),
);
$os
->filesystem()
->mount(Path::of('var/logs/'))
->get(Name::of('prod.log'))
->map(static fn($file) => $file->content())
->map($read)
->map(
static fn($logs) => $logs
->filter(
static fn($log) => $log
->attribute('level')
->filter(static fn($level) => $level->value() === LogLevel::CRITICAL)
->match(
static fn() => true,
static fn() => false,
),
)
->foreach(
static fn($log) => $log
->attribute('message')
->match(
static fn($attribute) => print($attribute->value()),
static fn() => print('No message found'),
),
),
static fn() => print('File does not exist'),
);The above example will print all messages that were logged at a critical level.
Note: if parsing the context or extra attributes of a monolog line fail they won't be exposed as attributes in the Log object. This behaviour is implemented to not make the whole parsing fail due to this error.
Note 2: if a line can't be parsed for some reason it will simply be ignored and not exposed. Again this behaviour is implemented to not make the whole parsing fail.
