Question

我有一个显示延迟数据的表，现在我想编写一个警报查询，该警报将在请求（方法+ uri）的中位数高于3000毫秒（3秒）时发出警报

我用于该延迟表的查询是：

index=ms-app  environment=prod AND "*"
| eval uri=replace(mvindex(split('request.uri', "?"), 0), "\/\d+[-+\w]+", "/:n"), methodOverride='request.headers.X-HTTP-Method-Override'
| eval methodOverrideStr = if(isnull(methodOverride) OR methodOverride=="null", "", "(" + methodOverride + ")")
| eval request = 'request.method' + methodOverrideStr + " " + uri + " " + 'response.httpStatusCode'
| stats
min(stats.overallResponseTimeInMilliSeconds) as "Min",
avg(stats.overallResponseTimeInMilliSeconds) as avg_latency,
max(stats.overallResponseTimeInMilliSeconds) as "Max",
median(stats.overallResponseTimeInMilliSeconds) as "Median",
perc95(stats.overallResponseTimeInMilliSeconds) as "95th %",
count(request) as "# req total", count(eval('stats.overallResponseTimeInMilliSeconds' > 3000)) as "#>3s",
count(eval('stats.overallResponseTimeInMilliSeconds' > 5000)) as "#>5s",
count(eval('stats.overallResponseTimeInMilliSeconds' > 10000)) as "#>10s" by request
| eval "Avg" = round(avg_latency, 0)
| table request, "Median"

这将产生一个基于方法+ uri的表格，显示中位潜伏期例如：

POST /第一个端点1000
获取/ second-endpoint 2000
删除/第三端点1500
POST /第四端点4000
获取/ fifth-endpoint 4500

现在，我正在尝试创建一个查询，该查询将仅显示中位数延迟高于3s的+ uri方法，以便我可以创建警报，以警告splunk哪些端点具有较高的延迟这就是我尝试过的：

index=ms-app  environment=prod AND "*"
| eval uri=replace(mvindex(split('request.uri', "?"), 0), "\/\d+[-+\w]+", "/:n"), methodOverride='request.headers.X-HTTP-Method-Override'
| eval methodOverrideStr = if(isnull(methodOverride) OR methodOverride=="null", "", "(" + methodOverride + ")")
| eval request = 'request.method' + methodOverrideStr + " " + uri + " " + 'response.httpStatusCode'
| stats
median(stats.overallResponseTimeInMilliSeconds) as "Median"
| table request, "Median" > 3000

应显示以下内容：

POST /第四端点4000
获取/ fifth-endpoint 4500

但是，它只显示与第一个查询相同的结果

使用where命令根据字段值过滤事件。

... | where Median > 3000
| table request, Median

如何使用Splunk搜索中值延迟超过3秒的事务类型
