Hi,
I wrote a code to get Esx server uptime using VISDK. My code connected to virtual center and collect the boot time (using runtime.bootTime) and the current time (using queryDateTime) for all the Esx servers which are in vc and calculate the uptime using the following
computation.
Esx_server_uptime = Esx_server_current_time - Esx_server_boottime
This ll works fine upto the Esxserver reboots.Once the Esx server is rebooted the Esx_server_current_time is less than the Esx_server_boottime.Esx_server_current_time is not updated.My code also calling refreshDateTimeSystem method to refresh DateTime related settings.i am getting correct Esx_server_current_time only after 30 minutes of the reboot.What is the reason this 30 mins delay how to resolve this?My code is running continuously for every 5 minutes. I need to get the correct Esx_server_current_time as soon as the server reboots.how to get this?
String[][] typeInfo = new String[][] { new String[] { "HostSystem", "name",
"runtime.connectionState","configManager.dateTimeSystem","runtime.bootTime"}};
ObjectContent[] ocary = getContentsRecursively(null, null, typeInfo, true);
if (ocary == null || ocary.length == 0)
{
return null;
}
DynamicProperty[] propary = null;
for(int jj=0; jj<ocary.length ; jj++)
{
propary = ocary[jj].getPropSet();
String hostname = "";
String hostStatus = "";
long bootTime = 0;
long currentEsxTime = 0;
if(propary==null )
{
continue;
}
int len =propary.length;
Hashtable refs = new Hashtable();
for(int jk=0;jk<len;jk++)
{
String propName = propary[jk].getName();
ArrayList al2 = (ArrayList) refs.get(propName);
if (al2 == null)
al2 = new ArrayList();
Object o = (Object) propary[jk].getVal();
al2.add(o);
refs.put(propName, al2);
}
if (refs == null || refs.size() == 0)
continue;
if (refs.containsKey("runtime.bootTime"))
{
ArrayList arr = (ArrayList)refs.get("runtime.bootTime");
Calendar cal_temp = (Calendar)arr.get(0);
Date dt_temp = cal_temp.getTime();
bootTime = dt_temp.getTime();
}
if (refs.containsKey("runtime.connectionState"))
{
ArrayList arr = (ArrayList)refs.get("runtime.connectionState");
HostSystemConnectionState connState = (HostSystemConnectionState)arr.get(0);
if (connState!=null)
{
hostStatus =""+connState;
}
}
if (refs.containsKey("name"))
{
ArrayList ar1 = (ArrayList)refs.get("name");
hostname = (String)ar1.get(0);
}
lastRunTime = System.currentTimeMillis();
if(hostStatus.equalsIgnoreCase("connected") )
{
if (refs.containsKey("configManager.dateTimeSystem"))
{
ArrayList arr = (ArrayList)refs.get("configManager.dateTimeSystem");
ManagedObjectReference dateTimeInfoRef = (ManagedObjectReference) arr.get(0);
if (dateTimeInfoRef != null && getService() != null)
{
lastRunTime = System.currentTimeMillis();
Calendar cal_temp = getService().queryDateTime(dateTimeInfoRef);
lastRunTime = System.currentTimeMillis();
if (cal_temp != null)
{
Date dt_temp = cal_temp.getTime();
currentEsxTime = dt_temp.getTime();
}
}
else
currentEsxTime = System.currentTimeMillis();
}
else
currentEsxTime = System.currentTimeMillis();
}
else
currentEsxTime = System.currentTimeMillis();
Long l_hostUptime = currentEsxTime - bootTime;
ht_HostUptimeDt.put(hostname,new Long(l_hostUptime));
}
Thanks,
