獲取告警信息相對而言比較簡單點，這里先陳述告警信息的pojo類，作為存儲告警信息的源頭（省略getter和setter方法）：

?

public class AlarmItem {//對象private String ObjectName;//狀態private ManagedEntityStatus overallStatus;//名稱private String alarmName;//觸發時間private Date time;//確認時間private Date acknowledgedTime;//確認者private String acknowledgedByUser;//是否被確認private Boolean acknowledged;}

?

以獲取主機告警信息為例：

?

public static List<AlarmItem> getHostAlarms(String hostName) throws Exception{List<AlarmItem> ansList = null;ManagedObjectReference hostmor = getHostByHostName(hostName);ansList = getAlarms(hostmor);return ansList;}

這里先根據主機名稱獲取主機的對象（HostSystem)，相關代碼可以參考前面的相關文章。

?

接下去就是獲取告警的方法getAlarms(ManagedObjectReference mor):

?

private static List<AlarmItem> getAlarms(ManagedObjectReference mor) throws Exception{List<AlarmItem> ansList = new ArrayList<AlarmItem>();List<AlarmState> list = vimPort.getAlarmState(alarmManager, mor);for(AlarmState alarmState : list){if(alarmState.getOverallStatus().toString().equals("YELLOW") || alarmState.getOverallStatus().toString().equals("RED")){AlarmItem alarmItem = new AlarmItem();ManagedObjectReference alarm = alarmState.getAlarm();if(alarm!=null){PropertyFilterSpec alarmFilterSpec = createAlarmFilterSpec(alarm);ArrayList<PropertyFilterSpec> listpfs = new ArrayList<PropertyFilterSpec>();listpfs.add(alarmFilterSpec);List<ObjectContent> listobjcont = retrievePropertiesAllObjects(listpfs);if(listobjcont != null){ObjectContent oc = (ObjectContent) listobjcont.get(0);AlarmInfo alarmInfo = (AlarmInfo) oc.getPropSet().get(0).getVal();alarmItem.setAlarmName(alarmInfo.getName());}}alarmItem.setAcknowledged(alarmState.isAcknowledged());alarmItem.setAcknowledgedByUser(alarmState.getAcknowledgedByUser());alarmItem.setAcknowledgedTime(DateConvert.convertToDate(alarmState.getAcknowledgedTime()));alarmItem.setOverallStatus(alarmState.getOverallStatus());alarmItem.setTime(DateConvert.convertToDate(alarmState.getTime()));alarmItem.setObjectName(getObjectName(alarmState.getEntity()));ansList.add(alarmItem);}}return ansList;} private static PropertyFilterSpec createAlarmFilterSpec(ManagedObjectReference eventHistoryCollectorRef){PropertySpec propSpec = new PropertySpec();propSpec.setAll(new Boolean(false));propSpec.getPathSet().add("info");propSpec.setType(eventHistoryCollectorRef.getType());ObjectSpec objSpec = new ObjectSpec();objSpec.setObj(eventHistoryCollectorRef);objSpec.setSkip(new Boolean(false));PropertyFilterSpec spec = new PropertyFilterSpec();spec.getPropSet().add(propSpec);spec.getObjectSet().add(objSpec);return spec;}private static String getObjectName(ManagedObjectReference mor) throws Exception{String objectName = null;PropertySpec propSpec = new PropertySpec();propSpec.setAll(new Boolean(false));propSpec.getPathSet().add("name");propSpec.setType(mor.getType());ObjectSpec objSpec = new ObjectSpec();objSpec.setObj(mor);objSpec.setSkip(new Boolean(false));PropertyFilterSpec spec = new PropertyFilterSpec();spec.getPropSet().add(propSpec);spec.getObjectSet().add(objSpec);ArrayList<PropertyFilterSpec> listpfs = new ArrayList<PropertyFilterSpec>();listpfs.add(spec);List<ObjectContent> listobjcont = retrievePropertiesAllObjects(listpfs);if(listobjcont != null){ObjectContent oc = (ObjectContent) listobjcont.get(0);objectName = (String) oc.getPropSet().get(0).getVal();}return objectName;}

這樣就可以獲取相關的主機告警信息。

?

對于其他的，比如虛擬機的告警信息就可以這樣：

?

public static List<AlarmItem> getVmAlarms(String vmName) throws Exception{List<AlarmItem> ansList = null;ManagedObjectReference hostmor = getVmByVmName(vmName);ansList = getAlarms(hostmor);return ansList;}

對于其他的譬如vCenter, Cluster, Datacenter的告警就不一一贅述了，相信看得懂上面代碼的小伙伴一定能很快的自己寫出實現的方法。

?
