I just started writing my first project in GoLang. I want to send logs to syslog(/var/log/syslog) file.
I am using zerolog(github.com/rs/zerolog) package to write logs. This is my how I am logging currently:
log.Error().Str("Event_name", Event_name).Msg("Invalid event")
It is printing logs to terminal but not to syslog file. Can someone give example or explain how to do that? Thanks in advance.
You should open the file /var/log/syslog and then set the output of your logger to that file:
output, err := os.OpenFile("/var/log/syslog", os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0666)
if err != nil {
// unhandled error
}
log.Error().Str("Event_name", Event_name).Msg("Invalid event")
log.Output(output)
By the way, you must have sudo privileges when reading/writing system files. this means that your executable must be run under sudo
