The HPe Synergy platform has a very comprehensive RESTFul API and makes collecting data a very simple process once you have the basics down with regards to authentication and necessary header information.
It's great to have access to this data since it can be combined with VMWare and Storage data to give us a better idea of the physical infrastructure and how it is utilized for SAN connectivity as an example. I'll talk more about this is in a later post, but for now we'll focus on the mechanics of pulling Synergy data.
For more information on how to get started, go to the HPe Documentation website.
You need to have the IP/hostname of the appliance and login credentials for at least read access. Login supports local and AD authentication.
We'll use the GO language with very basic code snippets to authenticate, grab a session ID and issue a GET request for Enclosures. The process is the same for a majority of the endpoints.
A few global variables we'll need throughout. Appliance needs to be changed to the hostname/IP of your installation.
//Global vars
//Session ID
var sessid string
//End points
var sessurl = "https://appliance/rest/login-sessions"
var encurl = "https://appliance/rest/enclosures"
Setup a client to support self-signed cert (if needed).
//self signed cert support
tr := &http.Transport{
TLSClientConfig: &tls.Config{InsecureSkipVerify : true},
}
client := &http.Client{Transport: tr}
Issue a POST with login data and required headers as noted below. X-Api-Version will depend on your installation. GET endpoint https://appliance/rest/version. Look at the currentVersion value.
For AD authentication, you'll need to include the authLoginDomain attribute and the username with username@mydomain.org format. Adjust to your installation.
//login data
//only needed in initial login. Will use session id afterwards
authdat := map[string]string{"userName": "username@ADdomain", "password": "mypassword", "authLoginDomain": "ADdomain", "loginMsgAck": "true"}
auth, _ := json.Marshal(authdat)
req, _ := http.NewRequest("POST", sessurl, bytes.NewBuffer(auth))
req.Header.Add("Content-Type", "application/json")
req.Header.Add("Accept", "application/json")
req.Header.Add("X-Api-Version", "800")
Make the client call and retrieve the sessionID from the response.
//Client SessionID call
resp, reqerr := client.Do(req)
if reqerr != nil {
fmt.Printf("%s", reqerr)
os.Exit(1)
} else {
//Capture Session ID
//the following resp data is []byte type
jsondat, resperr := ioutil.ReadAll(resp.Body)
if resperr != nil {
fmt.Printf("%s", resperr)
os.Exit(1)
}
resp.Body.Close()
var jdat map[string]interface{}
if err := json.Unmarshal(jsondat, &jdat); err != nil {
panic(err)
}
sessid = jdat["sessionID"].(string)
}
Now we can add session id to the header via the auth keyword. We'll then call the enclosures endpoint and process some basic information for example purposes.
This utilizies struct. I have the enclosures struct provided below. I used JSON-to-Go to convert a sample json response to GO struct in this case.
//Actual data call
//Enclosures
reqenc, _ := http.NewRequest("GET", encurl, nil)
reqenc.Header.Add("Content-Type", "application/json")
reqenc.Header.Add("Accept", "application/json")
reqenc.Header.Add("X-Api-Version", "800")
reqenc.Header.Add("auth", sessid )
respenc, reqerrenc := client.Do(reqenc)
if reqerrenc != nil {
fmt.Printf("%s", reqerrenc)
os.Exit(1)
} else {
jsondat2, resperr2 := ioutil.ReadAll(respenc.Body)
if resperr2 != nil {
fmt.Printf("%s", resperr2)
os.Exit(1)
}
respenc.Body.Close()
var jdat2 Enclosures
if err := json.Unmarshal(jsondat2, &jdat2); err != nil {
panic(err)
}
fmt.Println("ENCLOSURES:")
for _, mem := range jdat2.Members {
fmt.Printf("Name: %s %s %s\n", mem.Name, mem.Status, mem.State)
for _, bay := range mem.DeviceBays {
fmt.Printf(" Bay: %v %s\n", bay.BayNumber, bay.DeviceBayType)
}
}
}
We issue a logout (DELETE) for the current session when complete.
//Logout
reqout, _ := http.NewRequest("DELETE", sessurl, nil)
reqout.Header.Add("Content-Type", "application/json")
reqout.Header.Add("Accept", "application/json")
reqout.Header.Add("X-Api-Version", "800")
reqout.Header.Add("auth", sessid )
respout, reqerrout := client.Do(reqout)
if reqerrout != nil {
fmt.Printf("%s", reqerrout)
os.Exit(1)
} else {
fmt.Println("Logout success")
}
respout.Body.Close()
