我正在使用 Prometheus 和 Grafana,并且正在尝试跟踪 Web 服务器应用程序。
我想绘制特定查询的平均持续时间(以毫秒为单位)。我想我可以从下面的数据中到达那里,但我很挣扎。
我的两组价值观:
rate(http_server_request_duration_seconds_sum[5m])
Element Value
{instance="dbserver:5000",job="control-tower",method="get",path="/api/control/v1/node/config.json"} 0.0010491088980113385

{instance="dbserver:5000",job="control-tower",method="put",path="/api/control/v1/agents/:id.json"}
rate(http_server_requests_total[5m])
Element Value

他们有不同的标签。为此,我只关心 path="/api/caption/v1/messages.json" 的位置。
我认为我需要使用速率、总和和“开”或“忽略”的组合,但我根本无法继续或忽略工作。
我可以通过以下方式获得分子(以秒为单位):
rate( http_server_request_duration_seconds_sum { path="/api/caption/v1/messages.json" }[5m])
这会返回:
{instance="dbserver:5000", job="control-tower", method="post", path="/api/caption/v1/messages.json"}
但是分母可以有不同的返回码,所以我必须将它们相加,我需要做一些忽略或打开或其他事情,但我还没有找到一个可以帮助我的例子,而且我真的很陌生。
任何人?
