使用VMware VSphere WebService SDK进行开发 （六）——检测告警信息

获取告警信息相对而言比较简单点，这里先陈述告警信息的pojo类，作为存储告警信息的源头（省略getter和setter方法）：

public class AlarmItem{//对象private String ObjectName;//状态private ManagedEntityStatus overallStatus;//名称private String alarmName;//触发时间private Date time;//确认时间private Date acknowledgedTime;//确认者private String acknowledgedByUser;//是否被确认private Boolean acknowledged;}

 

以获取主机告警信息为例：

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

这里先根据主机名称获取主机的对象（HostSystem)，相关代码可以参考前面的相关文章。

接下去就是获取告警的方法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;}

这样就可以获取相关的主机告警信息。

对于其他的，比如虚拟机的告警信息就可以这样：

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

对于其他的譬如vCenter, Cluster, Datacenter的告警就不一一赘述了，相信看得懂上面代码的小伙伴一定能很快的自己写出实现的方法。
