Response Structure

cacheGroups

An array of objects representing each of the Cache Groups being monitored within this CDN

coordinates

An object representing the geographic location of this Cache Group

latitude: This Cache Group’s latitude as a floating-point number
longitude: This Cache Group’s longitude as a floating-point number

name

A string that is this Cache Group’s name

config

A collection of parameters used to configure the monitoring behaviour of Traffic Monitor

health.polling.interval: An interval in milliseconds on which to poll for cache statistics
heartbeat.polling.interval: An interval in milliseconds on which to poll for health statistics. If missing, defaults to health.polling.interval.
tm.polling.interval: The interval at which to poll for configuration updates

deliveryServices

An array of objects representing each Delivery Service provided by this CDN

status: The Delivery Service’s status
totalKbpsThreshold: A threshold rate of data transfer this Delivery Service is configured to handle, in Kilobits per second
totalTpsThreshold: A threshold amount of transactions per second that this Delivery Service is configured to handle
xmlId: A string that is the Delivery Service’s XMLID

profiles

An array of the Profiles in use by the cache servers and Delivery Services belonging to this CDN

name

A string that is the Profile’s Name

parameters

An array of the Parameters in this Profile that relate to monitoring configuration. This can be null if the servers using this Profile cannot be monitored (e.g. Traffic Routers)

health.connection.timeout: A timeout value, in milliseconds, to wait before giving up on a health check request
health.polling.url: A URL to request for polling health. Substitutions can be made in a shell-like syntax using the properties of an object from the "trafficServers" array
health.threshold.availableBandwidthInKbps: The total amount of bandwidth that servers using this profile are allowed - across all network interfaces - in Kilobits per second. This is a string and using comparison operators to specify ranges, e.g. “>10” means “more than 10 kbps”
health.threshold.loadavg: The UNIX loadavg at which the server should be marked “unhealthy”

See also

uptime(1)
health.threshold.queryTime: The highest allowed length of time for completing health queries (after connection has been established) in milliseconds
history.count: The number of past events to store; once this number is reached, the oldest event will be forgotten before a new one can be added

type

A string that names the Profile’s Type

trafficMonitors

An array of objects representing each Traffic Monitor that monitors this CDN (this is used by Traffic Monitor’s “peer polling” function)

fqdn: An FQDN that resolves to the IPv4 (and/or IPv6) address of the server running this Traffic Monitor instance
hostname: The hostname of the server running this Traffic Monitor instance
ip6: The IPv6 address of this Traffic Monitor - when applicable
ip: The IPv4 address of this Traffic Monitor
port: The port on which this Traffic Monitor listens for incoming connections
profile: A string that is the Name of the Profile assigned to this Traffic Monitor
status: The status of the server running this Traffic Monitor instance

trafficServers

An array of objects that represent the cache servers being monitored within this CDN

cacheGroup

The Cache Group to which this cache server belongs

fqdn

An FQDN that resolves to the cache server’s IPv4 (or IPv6) address

hashId

The (short) hostname for the cache server - named “hashId” for legacy reasons

hostName

The (short) hostname of the cache server

port

The port on which the cache server listens for incoming connections

profile

A string that is the Name of the Profile assigned to this cache server

status

The status of the cache server

type

A string that names the Type of the cache server - should (ideally) be either EDGE or MID

interfaces

A set of the network interfaces in use by the server. In most scenarios, only one will be present, but it is illegal for this set to be an empty collection.

ipAddresses

A set of objects representing IP Addresses assigned to this network interface. In most scenarios, only one or two (usually one IPv4 address and one IPv6 address) will be present, but it is illegal for this set to be an empty collection.

address: The actual IP address, including any mask as a CIDR-notation suffix
gateway: Either the IP address of the network gateway for this address, or null to signify that no such gateway exists
serviceAddress: A boolean that describes whether or not the server’s main service is available at this IP address. When this property is true, the IP address is referred to as a “service address”. It is illegal for a server to not have at least one service address. It is also illegal for a server to have more than one service address of the same address family (i.e. more than one IPv4 service address and/or more than one IPv6 address). Finally, all service addresses for a server must be contained within one interface - which is therefore sometimes referred to as the “service interface” for the server.

maxBandwidth

The maximum healthy bandwidth allowed for this interface. If bandwidth exceeds this limit, Traffic Monitors will consider the entire server unhealthy - which includes all configured network interfaces. If this is null, it has the meaning “no limit”. It has no effect if monitor is not true for this interface.

Health Protocol

monitor

A boolean which describes whether or not this interface should be monitored by Traffic Monitor for statistics and health consideration.

mtu

The MTU of this interface. If it is null, it may be assumed that the information is either not available or not applicable for this interface.

name

The name of the interface. No two interfaces of the same server may share a name. It is the same as the network interface’s device name on the server, e.g. eth0.
