How to know which server is online or offline in a OAM cluster - oam

Question

Hello I´ve a problem when I try to monitor which one of a cluster oam servers is online and offline I use the the getServerDiagnosticInfo() method of AccessClient class from aSDK, but the Hashtable that returns only contains Keys (name and port of server) and Values that contains another HashTable (ObKeyMapVal a subtype of HashTable) but I think that this object must contains the health, server port, server name and number of connections as mentioned in the API doc but when I print the size and contents of it only prints "0" and [] (its empty)
snippet:
try{
AccessClient ac = AccessClient.createDefaultInstance("/dir",AccessClient.CompatibilityMode.OAM_10G);
Hashtable info = ac.getServerDiagnosticInfo();
Set<?> servers = info.keySet();
Collection<?> serverInfo = info.values();
System.out.println("Num of servers: " + servers.size());
Iterator it = servers.iterator();
Object servidor = null;
Object dato = null;
while(it.hasNext()){
servidor = it.next();
System.out.println("Server: " + servidor);
dato = info.get(servidor);
System.out.println("Data: " + dato);
ObKeyValMap ob = (ObKeyValMap) dato;
System.out.println("Size: " + ob.keySet().size());
System.out.println("Is Empty: " + ob.keySet().isEmpty());
System.out.println("Properties: " + ob.keySet());
}
ac.shutdown();
} catch (oracle.security.am.asdk.AccessException e) {
e.printStackTrace();
} catch (Exception e){
e.printStackTrace();
}
And got the next output:
Num of servers: 2
Server: myserver1.com5575
Data: {}
Size: 0
Is Empty: true
Properties: []
Server: myserver2.com5575
Data: {}
Size: 0
Is Empty: true
Properties: []
Thanks for your help !!!

Once you get the OAM Server Host and Port using getServerDiagnosticInfo(). Try to do telnet ( I am not Java Expert, following link may help How to connect/telnet to SPOP3 server using java (Sockets)?) , if the server is up the telnet session will be established.
