Types ¶
type History ¶
History represents the ping history for a single node/device.
func NewHistory ¶
NewHistory creates a new History object with a specific capacity.
func (*History) ComputeAndClear ¶
ComputeAndClear aggregates the result history into a single data point and clears the result set.
type Metrics ¶
type Metrics struct {
PacketsSent int // number of packets sent
PacketsLost int // number of packets lost
Best time.Duration // best rtt
Worst time.Duration // worst rtt
Median time.Duration // median rtt
Mean time.Duration // mean rtt
StdDev time.Duration // std deviation
}
Metrics is a dumb data point computed from a history of Results.
type Monitor ¶
type Monitor struct {
HistorySize int // Number of results per target to keep
PayloadSize uint16
Privileged bool
// contains filtered or unexported fields
}
Monitor manages the goroutines responsible for collecting Ping RTT data.
func New ¶
New creates and configures a new Ping instance. You need to call AddTarget()/RemoveTarget() to manage monitored targets.
func (*Monitor) AddTarget ¶
AddTarget adds a target to the monitored list. If the target with the given ID already exists, it is removed first and then readded. This allows the easy restart of the monitoring.
func (*Monitor) Export ¶
Export calculates the metrics for each monitored target and returns it as a simple map.
func (*Monitor) RemoveTarget ¶
RemoveTarget removes a target from the monitoring list.
