data SyslogMsg Source #

Message type that contains priority and message text.

Constructors

SyslogMsg Priority ByteString

Instances

LogMessage SyslogMsg Source #
Methods toMsg :: SyslogMsg -> ByteString #

syslogLogger :: MonadBase IO m => Logger m SyslogMsg Source #

Syslog Logger

runSyslog Source #

Arguments

:: (MonadBase IO m, MonadBaseControl IO (Eff r), Lifted m r)
=> String	Syslog ident
-> [Option]	Syslog options
-> Facility	Syslog facility
-> Eff (LogM m SyslogMsg ': r) a
-> Eff r a

Wrapper around runLogM and withSyslog

getLogMask :: MonadBase IO m => m [Priority] Source #

Get syslog log mask. Implemented as a wrapper around hsyslog's setlogmask

setLogMask :: MonadBase IO m => [Priority] -> m () Source #

Set syslog log mask Implemented as a wrapper around hsyslog's setlogmask

logSyslog :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => Priority -> l -> Eff r () Source #

Log some text to syslog

logDebug :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => l -> Eff r () Source #

logInfo :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => l -> Eff r () Source #

logNotice :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => l -> Eff r () Source #

logWarning :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => l -> Eff r () Source #

logError :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => l -> Eff r () Source #

logCritical :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => l -> Eff r () Source #

logAlert :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => l -> Eff r () Source #

logEmergency :: (LogMessage l, MonadBase IO m, Member (LogM m SyslogMsg) r, Lifted m r) => l -> Eff r () Source #

data Priority :: * #

Log messages are prioritized with one of the following levels:

>>> [minBound..maxBound] :: [Priority]
[Emergency,Alert,Critical,Error,Warning,Notice,Info,Debug]

The Ord instance for Priority considers the more urgent level lower than less urgent ones:

>>> Emergency < Debug
True
>>> minimum [minBound..maxBound] :: Priority
Emergency
>>> maximum [minBound..maxBound] :: Priority
Debug

Constructors

Emergency	the system is unusable
Alert	action must be taken immediately
Critical	critical conditions
Error	error conditions
Warning	warning conditions
Notice	normal but significant condition
Info	informational
Debug	debug-level messages

data Option :: * #

The function openlog allows one to configure a handful of process-wide options that modify the bahavior of the syslog funcion. These options are pid, cons, odelay, and ndelay.

Constructors

LogPID	Log the pid with each message.
Console	Log on the console if errors occur while sending messages.
DelayedOpen	Delay all initialization until first `syslog()` call (default).
ImmediateOpen	Initalize the syslog system immediately.
DontWaitForChildren	The syslog system should not attempt to wait for child process it may have created. This option is required by applications who enable `SIGCHLD` themselves.
