Types

type Collector

type Collector interface {
	// Get new metrics and expose them via prometheus registry.
	Update(ch chan<- prometheus.Metric) (err error)
}

Interface a collector has to implement.

func NewBondingCollector

func NewBondingCollector() (Collector, error)

NewBondingCollector returns a newly allocated bondingCollector. It exposes the number of configured and active slave of linux bonding interfaces.

func NewDiskstatsCollector

func NewDiskstatsCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing disk device stats.

func NewFileFDStatCollector

func NewFileFDStatCollector() (Collector, error)

NewFileFDStatCollector returns a new Collector exposing file-nr stats.

func NewFilesystemCollector

func NewFilesystemCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing Filesystems stats.

func NewGmondCollector

func NewGmondCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector scraping ganglia.

func NewIPVSCollector

func NewIPVSCollector() (Collector, error)

NewIPVSCollector sets up a new collector for IPVS metrics. It accepts the "procfs" config parameter to override the default proc location (/proc).

func NewInterruptsCollector

func NewInterruptsCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing interrupts stats

func NewLastLoginCollector

func NewLastLoginCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing load, seconds since last login and a list of tags as specified by config.

func NewLoadavgCollector

func NewLoadavgCollector() (Collector, error)

Take a prometheus registry and return a new Collector exposing load average.

func NewMdadmCollector

func NewMdadmCollector() (Collector, error)

Just returns the pointer to an empty struct as we only use throwaway-metrics.

func NewMegaCliCollector

func NewMegaCliCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing RAID status through megacli.

func NewMeminfoCollector

func NewMeminfoCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing memory stats.

func NewNetDevCollector

func NewNetDevCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing network device stats.

func NewNetStatCollector

func NewNetStatCollector() (Collector, error)

NewNetStatCollector takes a returns a new Collector exposing network stats.

func NewNtpCollector

func NewNtpCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing the offset between ntp and the current system time.

func NewRunitCollector

func NewRunitCollector() (Collector, error)

func NewSockStatCollector

func NewSockStatCollector() (Collector, error)

NewSockStatCollector returns a new Collector exposing socket stats.

func NewStatCollector

func NewStatCollector() (Collector, error)

Takes a prometheus registry and returns a new Collector exposing kernel/system statistics.

func NewSupervisordCollector

func NewSupervisordCollector() (Collector, error)

func NewTCPStatCollector
