Example REST API Client

This is an implementation of a cAdvisor REST API in Go. You can use it like this:

client, err := client.NewClient("http://192.168.59.103:8080/")

Obviously, replace the URL with the path to your actual cAdvisor REST endpoint.

MachineInfo
client.MachineInfo()

There is no v2 MachineInfo API, so the v2 client exposes the v1 MachineInfo

(*v1.MachineInfo)(0xc208022b10)({
 NumCores: (int) 4,
 MemoryCapacity: (int64) 2106028032,
 Filesystems: ([]v1.FsInfo) (len=1 cap=4) {
  (v1.FsInfo) {
   Device: (string) (len=9) "/dev/sda1",
   Capacity: (uint64) 19507089408
  }
 }
})

You can see the full specification of the MachineInfo struct in the source

VersionInfo
client.VersionInfo()

This method returns the cAdvisor version.

Attributes
client.Attributes()

This method returns a cadvisor/info/v2/Attributes struct with all the fields filled in. Attributes includes hardware attributes (as returned by MachineInfo) as well as software attributes (eg. software versions). Here is an example return value:

(*v2.Attributes)({
 KernelVersion: (string) (len=17) "3.13.0-44-generic"
 ContainerOsVersion: (string) (len=18) "Ubuntu 14.04.1 LTS"
 DockerVersion: (string) (len=9) "1.5.0-rc4"
 CadvisorVersion: (string) (len=6) "0.10.1"
 NumCores: (int) 4,
 MemoryCapacity: (int64) 2106028032,
 Filesystems: ([]v2.FsInfo) (len=1 cap=4) {
  (v2.FsInfo) {
   Device: (string) (len=9) "/dev/sda1",
   Capacity: (uint64) 19507089408
  }
 }
})

You can see the full specification of the Attributes struct in the source

NewClient returns a new client with the specified base URL.

func (*Client) Attributes

func (self *Client) Attributes() (attr *v2.Attributes, err error)

Attributes returns hardware and software attributes of the machine.

func (*Client) MachineInfo

func (self *Client) MachineInfo() (minfo *v1.MachineInfo, err error)

MachineInfo returns the JSON machine information for this client. A non-nil error result indicates a problem with obtaining the JSON machine information data.

func (*Client) MachineStats added in v0.20.2

func (self *Client) MachineStats() ([]v2.MachineStats, error)

MachineStats returns the JSON machine statistics for this client. A non-nil error result indicates a problem with obtaining the JSON machine information data.

func (*Client) Stats added in v0.21.0

func (self *Client) Stats(name string, request *v2.RequestOptions) (map[string]v2.ContainerInfo, error)

Stats returns stats for the requested container.

func (*Client) VersionInfo

func (self *Client) VersionInfo() (version string, err error)

VersionInfo returns the version info for cAdvisor.
