IBM TBSM 业务关联规则配置一例

最近在公司的项目中使用IBM TBSM进行业务关联配置工作,整个模型描述大概如下:

从模型设计角度来看该业务系统如下:

服务状态    B

业务节点    C1 ,D2 ,E3

业务资源    C11,C12,C13, D21,D22,D31,E32 

其中业务节点B1,B2,B3还要设置weight重要度

业务规则:

当业务资源发生黄色事件时,影响业务节点为黄色,业务总体状态为黄色

当业务资源发生红色事件是,如果业务节点weight=1,影响业务节点为红色,业务总体状态为红色,当weight=0时,影响业务节点为红色,业务总体状态为黄色。

在TBSM模板配置中,

首先建立数字聚集规则获取业务资源的最严重状态,得到C,D,E的节点状态

由于要参考weight的值,所以建立数字公示规则,计算业务状态B的值。

公示脚本如下:

log("Name value: " + ServiceInstance.DisplayName); log(0, "Child value: " + ServiceInstance.NUMCHILDREN); log(0, "Weight value: " + ServiceInstance.Weight); log(0, "STATUS value: " + int(ServiceInstance.RADSTATUS)); log(0, "STATUS1 value: " + InstanceNode.URM_APP_STATUS1.Value);

if ( int(InstanceNode.URM_STATUS.value) <> 2 and int(ServiceStatus) >= 3 and int(ServiceInstance.Weight) = 0) {   log(0, "filter a:");   Values = 3; } elseif ( int(InstanceNode.URM_STATUS.value) <> 2 and int(ServiceStatus) >= 3 and int(ServiceStatus) < 5 and int(ServiceInstance.Weight) = 1) { log(0, "filter b:");

  Values = 3; } elseif ( int(InstanceNode.URM_STATUS.value) <> 2 and int(ServiceStatus) = 5 and int(ServiceInstance.Weight) = 1 ) {   Values = 5; } else {   Values = 0; } log(0, "Values: " + Values);

Status = Values;

按照IBM 业务的定义,当资源发生状态改变时,先调用数字聚集规则,产生状态变化,在调用数字公式规则计算业务状态,但是在实际使用中发现服务状态总是无法恢复。尝试分析了一下感觉TBSM在系统流程中当数字聚集规则返回状态发生变化时,修改服务状态同时调用了数字公式规则,但此时可能未对ServiceStatus进行加锁操作,导致对ServiceStatus产生了一些并行操作,导致状态计算问题(这个地方可能一般实施人员看不懂,和IBM沟通了几次也没说清楚这个问题,他们一直说他们的产品没问题,按照他们的要求也改过几次脚本,无法解决这个问题,后来想了一个土办法,在脚本中判断一下所有资源的状态,来解决服务恢复问题,参考如下脚本)

log("Name value: " + ServiceInstance.DisplayName); log(0, "Child value: " + ServiceInstance.NUMCHILDREN);

  log(0, "Weight value: " + ServiceInstance.Weight); log(0, "STATUS value: " + int(ServiceInstance.RADSTATUS)); log(0, "STATUS1 value: " + InstanceNode.URM_APP_STATUS1.Value);

ServiceStatus = InstanceNode.URM_APP_STATUS1.Value; if( ServiceStatus < InstanceNode.URM_APP_STATUS2.Value) {     ServiceStatus = InstanceNode.URM_APP_STATUS2.Value;     } SevStatus = ServiceInstance.RADSTATUS;

if( SevStatus > ServiceStatus ) {   ServiceStatus = SevStatus ; } index1=0; index = 0; count = 0; red = 0; yellow = 0; green = 0; nodesum =1; nodesum = ServiceInstance.NUMCHILDREN;

while( index1 < ServiceInstance.NUMCHILDREN) {   log("ChildName value: " + ServiceInstance.CHILDINSTANCEBEANS[index1].DisplayName);   log("ChildRad value: " + ServiceInstance.CHILDINSTANCEBEANS[index1].RADSTATUS);

    if( ServiceInstance.CHILDINSTANCEBEANS[index1].RADSTATUS = 0)     {    green = green + 1; }     if( ServiceInstance.CHILDINSTANCEBEANS[index1].RADSTATUS = 3)      {   yellow = yellow + 1; }     if( ServiceInstance.CHILDINSTANCEBEANS[index1].RADSTATUS = 5)      {   red = red + 1; }

    index1 = index1 +1; }   log(0, "green: " + green); if( green=nodesum) {

   ServiceStatus = 0; } log(0, "yellow: " + yellow); if( yellow > 0 ) {       ServiceStatus = 3;   } if( nodesum >0) {     reddiv = red/nodesum;     log(0, "red: " + red);     log(0, "nodesum: " + nodesum);     if( reddiv  >= 0.51)     {         log(0, "red/nodesum: " + reddiv);         ServiceStatus = 5;     }else{          if( reddiv > 0 )          {               ServiceStatus = 3;          }

    } } if ( int(InstanceNode.URM_STATUS.value) <> 2 and int(ServiceStatus) >= 3 and int(ServiceInstance.Weight) = 0) {   log(0, "filter a:");   Values = 3; } elseif ( int(InstanceNode.URM_STATUS.value) <> 2 and int(ServiceStatus) >= 3 and int(ServiceStatus) < 5 and int(ServiceInstance.Weight) = 1) { log(0, "filter b:");

  Values = 3; } elseif ( int(InstanceNode.URM_STATUS.value) <> 2 and int(ServiceStatus) = 5 and int(ServiceInstance.Weight) = 1 ) {   Values = 5; } else {   Values = 0; } log(0, "Values: " + Values);

Status = Values;
