# Example REST API Client
This is an implementation of a cAdvisor REST API in Go. You can use it like this:
```go
client, err := client.NewClient("http://192.168.59.103:8080/")
```
Obviously, replace the URL with the path to your actual cAdvisor REST endpoint.
### MachineInfo
```go
client.MachineInfo()
```
There is no v2 MachineInfo API, so the v2 client exposes the [v1 MachineInfo](../../info/v1/machine.go#L131)
```
(*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](../../info/v1/machine.go#L131)
### VersionInfo
```go
client.VersionInfo()
```
This method returns the cAdvisor version.
### Attributes
```go
client.Attributes()
```
This method returns a [cadvisor/info/v2/Attributes](../../info/v2/machine.go#L24) 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
}
}
})
```
