Syslog hook doesn't log anything about logrus

[sirupsen]

Quite true. The default formatters set this. The hook then switches on the level. Did you write your own?

I didn't set a customer formatter. I am doing that:

log.SetOutput(os.Stderr)
log.SetLevel(log.WarnLevel)
log.SetLevel(log.DebugLevel)
log.WithField("file", "something").
                Debug("main: parsing configuration file")
syslogOutput, err := logrus_syslog.NewSyslogHook("", "",
                 syslog.LOG_INFO|syslog.LOG_DAEMON, "")
if err != nil {
                  log.Fatal("main: unable to setup syslog output")
}
log.AddHook(syslogOutput)
log.WithField("listen", "something").
                Info("proxy: start serving requests")

Did you try debugging it from the hook? That seems strange.

Why are you setting the level twice?

That's a partial code. I am checking if user asked for more debug and
then check to debug. It was just to show you that I may doing
"inappropriate" stuff like start logging stuff before setting the syslog

hook.

Here is a self contained example:

package main

import (
        log "github.com/Sirupsen/logrus"
        "github.com/Sirupsen/logrus/hooks/syslog"
        "log/syslog"
    "os"
)

func main() {
        /* Setup initial logging */
        log.SetOutput(os.Stderr)
    log.SetLevel(log.DebugLevel)
    syslogOutput, err := logrus_syslog.NewSyslogHook("", "",
        syslog.LOG_INFO|syslog.LOG_DAEMON, "")
    if err != nil {
        log.Fatal("main: unable to setup syslog output")
    }
    log.AddHook(syslogOutput)
    log.Debug("main: this should go to syslog")
}

If I leave syslog.go unchanged, nothing gets logged to syslog. It seems that this is the same problem as with #72. I'll do a pull request for that in a few minutes.

Once fixed, I still have that in syslog:

Nov 23 17:53:23 neo ./test1[31584]: #033[34mDEBU#033[0m[0000] main: this should go to syslog

I wouldn't expect the formatter to be attached only to a given output.
