syslog for OpenOS
This package contains a syslog library, and a syslog daemon, for OpenOS. These are separated, as the daemon is optional and can be replaced at will.
Installation
Library:
oppm install libsyslog
Daemon:
oppm install syslogd
Usage
Library
The syslog library only provides one function, so the library can be called. In addition, the library provides a number of pre-configured event levels:
- syslog.emergency
- syslog.alert
- syslog.critical
- syslog.error
- syslog.warning
- syslog.notice
- syslog.info
- syslog.debug
An example using syslog as both a function and a table:
local syslog = require "syslog"
syslog("message", syslog.emergency, "service name")
Daemon
The syslog daemon lives in /etc/rc.d/syslogd.lua, and as such is managed as an rc program:
rc syslogd enable
rc syslogd start
rc syslogd reload
In addition, the daemon keeps a configuration file in /etc/syslogd.cfg. This is stored as a Lua table and may be edited in whatever way you see fit. It has the following fields and default values:
| Field | Default value |
|---|---|
| port | 514 |
| relay | false |
| relayhost | "" |
| receive | false |
| write | true |
| destination | "/dev/null" |
| minlevel | 6 |
| beeplevel | -1 |
| displevel | 2 |
| filter | {} |
Technical details
The syslog library and daemon communicate via events, namely a syslog event. The format is as follows:
"syslog", message, level, service
