var Status = [3]string{
	"up",
	"standby",
	"failed",
}

Status defines the possible states of a collector

Functions

func GetBuiltinPlugin 

func GetBuiltinPlugin(name string, abc *plugin.AbstractPlugin) plugin.Plugin

GetBuiltinPlugin returns built-in plugin with name if it exists, otherwise nil

func ImportTemplate 

func ImportTemplate(confPaths []string, templateName, collectorName string) (*node.Node, error)

ImportTemplate looks for a collector's template by searching confPaths for the first template that exists in confPath/collectorName/templateName

func Init 

func Init(c Collector) error

Init initializes a collector and does the trick of "inheritance", hence a function and not a method. A collector can choose to call this function inside its Init method, or leave it to be called by the poller during dynamic load.

The important thing done here is to look what tasks are defined in the "schedule" parameter of the collector and create a pointer to the corresponding method of the collector. Example, parameter is:

schedule: 

data: 10s
instance: 20s

then we expect that the collector has methods PollData and PollInstance that need to be invoked every 10 and 20 seconds respectively. Names of the polls are arbitrary, only "data" is a special case, since plugins are executed after the data poll (this might change).

func SendAutosupport 

func SendAutosupport(collectors []Collector, status *matrix.Matrix, pollerName string) error

Types

type AbstractCollector 

type AbstractCollector struct {
	Name    string           // name of the collector, CamelCased
	Object  string           // object of the collector, describes what that collector is collecting
	Logger  *logging.Logger  // logger used for logging
	Status  uint8            // current state of th
	Message string           // reason if a collector is in failed state
	Options *options.Options // poller options
	Params  *node.Node       // collector parameters
	// note that this is a merge of poller parameters, collector conf and object conf ("subtemplate")
	Schedule  *schedule.Schedule         // schedule of the collector
	Matrix    map[string]*matrix.Matrix  // the data storage of the collector
	Metadata  *matrix.Matrix             // metadata of the collector, such as poll duration, collected data points etc.
	Exporters []exporter.Exporter        // the exporters that the collector will emit data to
	Plugins   map[string][]plugin.Plugin // built-in or custom plugins

	Auth        *auth.Credentials // used for authing the collector
	HostVersion string
	HostModel   string
	HostUUID    string
	// contains filtered or unexported fields
}

AbstractCollector implements all required attributes of Collector. A "real" collector will "inherit" all these attributes and has the option to override them. The real collector should implement at least one poll function (usually PollData). AbstractCollector will link these functions to its Schedule and make sure that they are properly and timely executed.

func New 

func New(name, object string, o *options.Options, params *node.Node, credentials *auth.Credentials) *AbstractCollector

func (*AbstractCollector) AddCollectCount 

func (c *AbstractCollector) AddCollectCount(n uint64)

AddCollectCount adds n to collectCount atomically

func (*AbstractCollector) CollectAutoSupport 

func (c *AbstractCollector) CollectAutoSupport(_ *Payload)

CollectAutoSupport allows a Collector to add autosupport information

func (*AbstractCollector) GetCollectCount 

func (c *AbstractCollector) GetCollectCount() uint64

GetCollectCount retrieves and resets count of collected data this and next method are only to report the poller how much data we have collected (independent of poll interval)

func (c *AbstractCollector) GetHostModel() string

func (*AbstractCollector) GetHostUUID 

func (c *AbstractCollector) GetHostUUID() string

func (*AbstractCollector) GetHostVersion 

func (c *AbstractCollector) GetHostVersion() string

func (*AbstractCollector) GetLogger

func (c *AbstractCollector) GetMetadata() *matrix.Matrix

func (*AbstractCollector) GetName 

func (c *AbstractCollector) GetName() string

func (*AbstractCollector) GetObject 

func (c *AbstractCollector) GetObject() string

GetObject returns object of the collector

func (*AbstractCollector) GetOptions 

func (c *AbstractCollector) GetOptions() *options.Options

GetOptions returns the poller options passed to the collector

func (*AbstractCollector) GetParams 

func (c *AbstractCollector) GetParams() *node.Node

GetParams returns the parameters of the collector

func (*AbstractCollector) GetStatus 

func (c *AbstractCollector) GetStatus() (uint8, string, string)

func (*AbstractCollector) ImportSubTemplate 

func (c *AbstractCollector) ImportSubTemplate(model, filename string, ver [3]int) (*node.Node, string, error)

ImportSubTemplate retrieves the best matching subtemplate of a collector object. This method is applicable to collectors which have multiple objects. Each object is forked as a separate collector. The sub-templates exist in subdirectories named after ONTAP versions. These directories are sorted, and we try to return the subtemplate that most closely matches the ONTAP version. Model is cdot or 7mode, filename is the name of the subtemplate, and ver is the ONTAP version triple (generation, major, minor)
