[Vijava-users] How to get ESX's local datastores information

[Nikunj B. <nik...@gm...>]

Hello All,

Is there a way to find out which datastores are local to my ESX server ?
The getDatastores() method of host mor obj gives all kind of datastores.
But I am interested in finding out only the ones which are local to the ESX
server and not coming from SAN ?

Example:

ESXSERVER
  |-> DS1 (local)
  |-> DS2 (SAN)
  |-> DS3 (SAN)
...
...


I need to find out all datastores of type DS1 which are local and not
shared by any other host.

Any pointers ?


Thanks.

[Vijava-users] Help with creating an alarm

[Nikunj B. <nik...@gm...>]

Hello All,

Cross posting on this mailing lists a post from Help forum.

https://sourceforge.net/p/vijava/discussion/823527/thread/7ebea289/?limit=25#3eae

I am trying to create an alarm for monitoring disk latency of virtual
machine.
The snippet looks like this:

============

public class DiskLatencyAlarmSpec extends AlarmSpec {
//Private variables definition come here..

public DiskLatencyAlarmSpec(String name) {
this.setName(name);
this.setDescription(DESCRIPTION);
this.setEnabled(true);
this.setExpression(getMetricAlarmExpression());
//getMetricAlarmExpression() returns an object of type
MetricAlarmExpression.
this.setSetting(getAlarmSetting()); //getAlarmSetting() returns an object
of type AlarmSetting.
}

//getMetricAlarmExpression() definition come here..
//getAlarmSetting() definition come here..

}

spec = DiskLatencyAlarmSpec("TestSpec");
alarm = createAlarm(getEntity(), spec); //getEntity() returns the managed
object type for the vm.

==============

When I do like this, I get "com.vmware.vim25.InvalidRequest" exception.

But when I simply create a new AlarmSpec() object (instead of inheritance)
and pass it to createAlarm() method, the alarm gets registered for the VM
just fine and I could see it in the vSphere client.

Any pointers on whats going on here ?

[Vijava-users] Help with registering an Alarm

[Nikunj B. <nik...@gm...>]

Hello All,

I am trying to register a disk latency alarm for a vm through vijava.

if disk latency goes above 10ms for 5 mins, then flag a warning (yellow). OR
if disk latency goes above 20ms for 5 mins, then flag an alert (red)

Here is my piece of code:

{{{
 637     ServerConnection sc = getVM().getServerConnection();
 638     // Method getVM(), returns the managed object for the VM.
 639
 640     AlarmManager alarmManager =
sc.getServiceInstance().getAlarmManager();
 641
 642     AlarmSpec alarmSpec = new AlarmSpec();
 643     alarmSpec.name = "VM Datastore Latency Tracker";
 644     alarmSpec.description = "This alarm is used to monitor disk
latency of my VM";
 645     alarmSpec.enabled = true;
 646
 647     OrAlarmExpression orAlarmExp = new OrAlarmExpression();
 648     alarmSpec.expression = orAlarmExp;
 649
 650     AlarmExpression[] alarmExp = new AlarmExpression[1];
 651     MetricAlarmExpression metricAlarmExp = new MetricAlarmExpression();
 652     alarmExp[0] = metricAlarmExp;
 653     MetricAlarmOperator metricAlarmOperator =
MetricAlarmOperator.isAbove;
 654     metricAlarmExp.operator = metricAlarmOperator;
 655     metricAlarmExp.type = "VirtualMachine";
 656     PerfMetricId perfMetric = new PerfMetricId();
 657     metricAlarmExp.metric = perfMetric;
 658     perfMetric.counterId = 133;                  //ID for disk latency
monitor
 659     perfMetric.instance = "";
 660     metricAlarmExp.yellow = 10;                //disk latency 10ms
 661     metricAlarmExp.yellowInterval = 300;
 662     metricAlarmExp.red = 20;
 663     metricAlarmExp.redInterval = 300;
 664
 665     AlarmSetting alarmSetting = new AlarmSetting();
 666     alarmSetting.toleranceRange = 0;
 667     alarmSetting.reportingFrequency = 0;
 668     alarmSpec.setting = alarmSetting;
 669     alarmManager.createAlarm(getVM(), alarmSpec);
 670     // End: CreateAlarm
 671
 672
}}}



When I run this, I get an exception saying that
"com.vmware.vim25.InvalidRequest: com.vmware.vim25.InvalidRequest"

Any pointers on how to resolve this ?

[Vijava-users] OVF import through vijava fails (discontinuous response stream the reason?)

[jaikiran p. <jai...@gm...>]

Hi,

We are using the latest released 5.5 beta vijava jar against our VCenter
whose version is VMware vCenter Server 5.1.0 build-799731. We are running
some sample code which is expected to import a ovf file to the vCenter
instance. The code just invokes on the OVFManager to create the import spec
but it consistently fails with the following exception every time it's
invoked:

18:37:03,712  INFO [OVFImporter] - Starting OVF read from URL :

This issue looks similar to what was blogged about here by Steve
http://www.doublecloud.org/2011/11/discontinuous-response-stream-from-vsphere/although
the operation being run is probably different.

We also tried this operation using the 5.1 version of vijava jar from our
client. But it runs into the same exception (I haven't digged deeper into
the root cause in that version).

Is there a way we can get past this issue? Let me know if more details are
needed or if you want me to try a few things through the code.

[Vijava-users] Strange java.lang.IllegalAccessException

[Mike K. <mi...@gm...>]

Hi vijava users,

I'm using the SDK to for creating/destroying VMs via vCenter and somehow I encounter a strange exception (see below). The strange thing about this problem is that functionality actually works well.

I'm using version 5.1 of the library and I'm sure that it's the only version on the classpath.

    java.lang.IllegalAccessException: Class com.vmware.vim25.ws.XmlGen can not access a member of class com.vmware.vim25.DynamicData with modifiers "private static transient"

It happens not only in getResource() call, but also Task.getTaskInfo(), ManagedObject.getPropertyByPath() and so on.

[Vijava-users] VIJava Support for ESX versions

[Pai, R. M. <roo...@hp...>]

Hi,

We understand that the primary advantage of the VI Java API is improved productivity due to a serious reduction in code - up to 70 percent and improved performance compared to VISDK.
We would like to know if :


1)      VIJava supports all the versions of ESX?  Will this API support all upcoming version of ESX?  What is the commitment of the VIJava towards this?

2)      What benefit is gives  in terms of memory,  cpu ?




Thanks,

[Vijava-users] How to run program/script on windows guest with vijava?

[Andrea T. <and...@em...>]

Hi all,

I'm using vijava since a while and now I'd like to run program/script
in Windows guest without using vnc, ssh or rdp. I know VMware provides
"vmrun" CLI to run this kind of tasks on guest where vmware tools is
installed. Is there any suppot of this functionalities in vijava
library?

thank you,
Andrea

[Vijava-users] How often is the vijava project updated?

[Bhushan J. <bhu...@gm...>]

Hi, I had a query regarding how often is the vijava project updated
corresponding to the updates in the VMware SDK? Do updates in VMware SDK get
incorporated in vijava instantaneously or what is the usual time time lag?
Please let me know

[Vijava-users] Linked clone creation

[Adam S. <ada...@gm...>]

Hello All,

Looking to see if anyone out there has something written they would be
willing to share or for any tips on generating linked clones using VI
Java.

I've done a bit of prototyping with the ghetto-linked-clones script
provided here: http://communities.vmware.com/docs/DOC-9020. This works
functionally for me, but since it needs to be executed from the ESX
host it's untenable in my environment without resorting to major
hackery (like SSH'ing to individual ESX machines and running the
script from a central machine).

Thanks in advance for any help, pointers, advice, code snippets that
you can provide.

Sincerely,
Adam
