Types

type Config

type Config map[string]interface{}

Config is a flat mapping where values are simple (no slices/maps).

func NewDNSConfig

func NewDNSConfig(host, domain string, port int, t string, respTimeout int) *Config

NewDNSConfig constructs/returns a job configuration for DNS type jobs. host is the IP address or hostname of the nameserver to query. (Required) domain name to query. (Required) port is the dns port to query on host. t is the type of the DNS record type to query. respTimeout is the timeout(in ms) after sending query to wait for the output.

func NewHTTPConfig

func NewHTTPConfig(url, method, ua, auth string, connTimeout int) *Config

NewHTTPConfig constructs/returns a job configuration for HTTP type jobs. url is the URL to query. (Required) method is the HTTP method(valid methods are HEAD, GET, and POST). ua is the user agent text in the request header. auth is the authorization header to use in request. connTimeout is the timeout(in sec) to wait for query output.

func NewHTTPV3Config

func NewHTTPV3Config(url, method, ua, auth string, connTimeout int, it time.Duration, reqIPV4 bool, vhost string, tlsSkipVerify bool, followRedir bool) *Config

NewHTTPV3Config constructs/returns a job configuration for HTTP type jobs, with additional V3 fields. v3 must be enabled in customer configuration url is the URL to query. (Required) method is the HTTP method(valid methods are HEAD, GET, and POST). ua is the user agent text in the request header. auth is the authorization header to use in request. connTimeout is the timeout(in sec) to wait for query output.

func NewPINGConfig

func NewPINGConfig(host string, timeout, count, interval int) *Config

NewPINGConfig constructs/returns a job configuration for PING type jobs. host is the IP address or hostname to ping. (Required) timeout is the timeout(in ms) before marking the host as failed. count is the number of packets to send. interval is the minimum time(in ms) to wait between sending each packet.

func NewTCPConfig

func NewTCPConfig(host string, port, connTimeout, respTimeout int, send string, ssl bool) *Config

NewTCPConfig constructs/returns a job configuration for TCP type jobs. host is the IP address or hostname to connect to. (Required) port is the tcp port to connect to on host. (Required) connTimeout is the timeout(in ms) before giving up on trying to connect. respTimeout is the timeout(in sec) after connecting to wait for output. send is the string to send to the host upon connecting. ssl determines whether to attempt negotiating an SSL connection.

type Job

type Job struct {
	ID string `json:"id,omitempty"`

	// The id of the notification list to send notifications to.
	NotifyListID string `json:"notify_list"`

	// Type of monitor to be run.
	// Available job types:
	//  - http: Do an HTTP request against a webserver
	//  - dns: Do a DNS lookup against a nameserver
	//  - tcp: Connect to a TCP port on a host
	//  - ping: Ping a host using ICMP packets
	Type string `json:"job_type"`

	// Configuration dictionary(key/vals depend on the jobs' type).
	Config Config `json:"config"`

	// The current status of the monitor.
	Status map[string]*Status `json:"status,omitempty"`

	// Rules for determining failure conditions.
	Rules []*Rule `json:"rules"`

	// List of regions in which to run the monitor.
	// eg, ["dal", "sin", "sjc", "lga", "ams"]
	Regions []string `json:"regions"`

	// Indicates if the job is active or temporarily disabled.
	Active bool `json:"active"`

	// Frequency(in seconds), at which to run the monitor.
	Frequency int `json:"frequency"`

	// The policy for determining the monitor's global status based
	// on the status of the job in all regions.
	// Available policies:
	//  - quorum: Status change when majority status
	//  - all: Status change only when all regions are in agreement
	//  - one: Status change if any region changes
	Policy string `json:"policy"`

	// Controls behavior of how the job is assigned to monitoring regions.
	// Currently this must be fixed — indicating monitoring regions are explicitly chosen.
	RegionScope string `json:"region_scope"`

	// Freeform notes to be included in any notifications about this job,
	// e.g., instructions for operators who will receive the notifications.
	Notes string `json:"notes,omitempty"`

	// A free-form display name for the monitoring job.
	Name string `json:"name"`

	// Time(in seconds) between repeat notifications of a failed job.
	// Set to 0 to disable repeating notifications.
	NotifyRepeat int `json:"notify_repeat"`

	// If true, on any apparent state change, the job is quickly re-run after
	// one second to confirm the state change before notification.
	RapidRecheck bool `json:"rapid_recheck"`

	// Time(in seconds) after a failure to wait before sending a notification.
	NotifyDelay int `json:"notify_delay"`

	// If true, notifications are sent for any regional failure (and failback if desired),
	// in addition to global state notifications.
	NotifyRegional bool `json:"notify_regional"`

	// If true the notification will be off
	Mute bool `json:"mute"`

	// If true, a notification is sent when a job returns to an "up" state.
	NotifyFailback bool `json:"notify_failback"`
}
