Functions ¶
func GetSettingValue ¶
GetSettingValue will get the value from the given settings. If the setting is not defined the function will return the given default value.
func ParseBool ¶
ParseBool will parse the boolean for the given settings name. When the setting is not defined we will use the given default.
func ParseDuration ¶
ParseDuration will parse the duration for the given settings name. When the setting is not defined we will use the given default.
func ParseFileMode ¶
ParseFileMode will parse the os.FileMode for the given settings name. When the setting is not defined we will use the given default.
func ParseInt ¶
ParseInt will parse the uint in base 10 for the given settings name. When the setting is not defined we will use the given default.
func ParseUint ¶
ParseUint will parse the uint in base 10 for the given settings name. When the setting is not defined we will use the given default.
func RecordFloat ¶
RecordFloat will take a metricname and a float value and record it to syslog.
func RecordUint ¶
RecordUint will take a metricname and a uint value and record it to syslog.
func Start ¶
Start will start a given service and return the message channel. This function can be run multible times and will always return the same message channel.
func WatchFloat ¶
WatchFloat will take a function that returns a float value and record the output of that function every DefaultWatchInterval.
func WatchInt ¶
WatchInt will take a function that returns a int value and record the output of that function every DefaultWatchInterval.
func WatchRuntimeMemory ¶
func WatchRuntimeMemory(name string)
WatchRuntimeMemory will record the runtime memory stats every DefaultWatchInterval.
func WatchSignals ¶
func WatchSignals()
WatchSignals waits for unix signals and handles them appropiatly. SIGINT/SIGTERM: Stop services and return. SIGHUP: Reload services. SIGQUIT: Dump core and return.
Types ¶
type Message ¶
type Message interface {
Type() MessageType
Source() string
}
type MessageError ¶
type MessageError struct {
Error error
// contains filtered or unexported fields
}
func (MessageError) Source ¶
func (me MessageError) Source() string
func (MessageError) Type ¶
func (me MessageError) Type() MessageType
