Vite Releases Technical Preview of Rolldown-Vite, a Rust-Based Bundler
Vite releases Rolldown-Vite, a Rust-based bundler preview offering faster builds and lower memory usage as a drop-in replacement for Vite.
This is the new GELF gem written by Alexey Palazhchenko. It is based on the old gem by Lennart Koopmann and allows you to send GELF messages to Graylog or Logstash instances. See the GELF specification for more information about GELF and RDoc for API documentation.
Tested with Ruby 1.9, 2.0, 2.1, 2.2, 2.3 and 2.4.
This allows you to sent arbitary messages via UDP to Graylog.
n = GELF::Notifier.new("localhost", 12201)
# Send with custom attributes and an additional parameter "foo"
n.notify!(:short_message => "foo", :full_message => "something here\n\nbacktrace?!", :_foo => "bar")
# Pass any object that responds to .to_hash
n.notify!(Exception.new)
The recommended default is to send via UDP but you can choose to send via TCP like this:
n = GELF::Notifier.new("127.0.0.1", 12201, "LAN", { :protocol => GELF::Protocol::TCP })
Note that the LAN
or WAN
option is ignored for TCP because no chunking happens. (Read below for more information.)
The Gelf::Logger is compatible with the standard Ruby Logger interface and can be used interchangeably. Under the hood it uses Gelf::Notifier to send log messages via UDP to Graylog.
logger = GELF::Logger.new("localhost", 12201, "WAN", { :facility => "appname" })
logger.debug "foobar"
logger.info "foobar"
logger.warn "foobar"
logger.error "foobar"
logger.fatal "foobar"
logger << "foobar"
Then WAN
or LAN
option influences the UDP chunk size depending on if you send in your own
network (LAN) or on a longer route (i.e. through the internet) and should be set accordingly.
Since it's compatible with the Logger interface, you can also use it in your Rails application:
# config/environments/production.rb
config.logger = GELF::Logger.new("localhost", 12201, "WAN", { :facility => "appname" })
