Logging to Syslog?

In Memento v0.4, the builtin Syslog type was moved into its own package Syslogs.jl which allows folks to use either Syslogs.jl or Memento.jl independently from one another. Unfortunately, this does require the following bit of glue code in your projects.

# Load up `Syslogs.jl` where `Syslog` will be exported by default.
using Syslogs

# Define a 2 line glue method as the `Syslog` type requires a level argument be passed into
# the `println` method.
function Memento.emit(handler::DefaultHandler{F, O}, rec::Record) where {F<:Formatter, O<:Syslog}
    println(handler.io, rec.level, format(handler.fmt, rec))
    flush(handler.io)
end

# NOTE: This glue code is only necessary because Julia (as of v0.7) doesn't provide a good
# mechanism for handling optional dependencies.

Now we can start logging to syslog locally:

push!(
    logger,
    DefaultHandler(
        Syslog(),
        DefaultFormatter("{level}: {msg}")
    )
)

We can also log to remote syslog servers via UDP or TCP:

push!(
    logger,
    DefaultHandler(
        Syslog(ip"123.34.56.78"),
        DefaultFormatter("{level}: {msg}")
    )
)
