根据结果​​替换参数

Question

在下面的脚本中，我们正在检查所选时间范围内的URL状态的平均可用性，以及最近3分钟的最新运行状况都正常，但是您知道日志分析数据注入的速度很慢，因为在最后一次检查时最新的健康状态持续3分钟，我们将获得空值，因此它会显示为不健康，但平均会显示为健康，因为用户选择了最近4小时的时间范围，然后会有所有健康状态的记录。

let start = {TimeRange:start};
let grain =  {TimeRange:grain};
workspace(name).login_CL
| extend healthy=iff(StatusCode_s == 'OK' , 100 , 0)
| where TimeGenerated>={TimeRange:end}-3m and TimeGenerated<={TimeRange:end}
| summarize Availability=avg(healthy) by EnvName_s, ClientName_s
| extend HealthStatus=0.000
| extend LatestHealthStatus=Availability
| project Client=ClientName_s,Environment=EnvName_s,HealthStatusAverage = HealthStatus,LatestHealthStatus
)
| union
workspace(name).login_CL
| extend healthy=iff(StatusCode_s == 'OK' , 100 , 0)
| where TimeGenerated>={TimeRange:start} and TimeGenerated<={TimeRange:end}
| summarize pageAvailability=avg(healthy) by EnvName_s, ClientName_s
| extend LatestHealthStatus=0.000
| extend HealthStatus=pageAvailability
| join
(  workspace(name).login_CL
| extend healthy=iff(StatusCode_s == 'OK' , 100 , 0)
| where TimeGenerated>={TimeRange:start} and TimeGenerated<={TimeRange:end}
| make-series lifeline = avg(healthy) on TimeGenerated from start to now() step grain by EnvName_s, ClientName_s
) 
on EnvName_s
| project  Environment=EnvName_s,HealthStatusAverage = HealthStatus,LatestHealthStatus,Lifeline=lifeline
| summarize AverageHealth=sum(HealthStatusAverage), 
  LatestHealth=sum(LatestHealthStatus),HearthbeatAvg=make_list(Lifeline) by 
  Environment

我们需要的是，如果最新健康状况由于任何原因不健康，平均水平也需要显示为不健康状况，我附上了工作簿的屏幕快照以供参考
