无法从指标查询语言 MQL - GCP 收集数据
Unable to collect data from metric query language MQL - GCP
我想使用以下库执行 MQL(度量查询语言)。
<dependency>
<groupId>com.google.apis</groupId>
<artifactId>google-api-services-monitoring</artifactId>
<version>v3-rev540-1.25.0</version>
</dependency>
这是我的代码片段。这将创建监控客户端并尝试从 GCP 监控中收集数据。
public void queryTimeSeriesData() throws IOException {
// create monitoring
Monitoring m = createAuthorizedMonitoringClient();
QueryTimeSeriesRequest req = new QueryTimeSeriesRequest();
String query = "fetch consumed_api\n" +
"| metric 'serviceruntime.googleapis.com/api/request_count'\n" +
"| align rate(2m)\n" +
"| every 2m\n" +
"| group_by [metric.response_code],\n" +
" [value_request_count_max: max(value.request_count)]";
req.setQuery(query);
HashMap<String, Object> queryTransformationSpec = new HashMap<String, Object>();
HashMap<String, Object> timingState = new HashMap<String, Object>();
HashMap<String, Object> absoluteWindow = new HashMap<String, Object>();
absoluteWindow.put("startTime", "2020-09-03T12:40:00.000Z");
absoluteWindow.put("endTime", "2020-09-03T13:41:00.000Z");
timingState.put("absoluteWindow", absoluteWindow);
timingState.put("graphPeriod", "60s");
timingState.put("queryPeriod", "60s");
queryTransformationSpec.put("timingState", timingState);
req.set("queryTransformationSpec", queryTransformationSpec);
req.set("reportPeriodicStats", false);
req.set("reportQueryPlan", false);
QueryTimeSeriesResponse res = m.projects().timeSeries().query("projects/MY_PROJECT_NAME", req).execute();
System.out.println(res);
}
上面的代码工作正常,但它没有返回给定 startTime 和 endTime 的数据,
它总是 returns 可用的最新数据点。我的代码有问题吗?
找到了在给定时间范围内执行 MQL 查询的方法。这
新的工作代码如下:
public void queryTimeSeriesData() throws IOException {
// create monitoring
Monitoring m = createAuthorizedMonitoringClient();
QueryTimeSeriesRequest req = new QueryTimeSeriesRequest();
String query = "fetch consumed_api\n" +
"| metric 'serviceruntime.googleapis.com/api/request_count'\n" +
"| align rate(5m)\n" +
"| every 5m\n" +
"| group_by [metric.response_code],\n" +
" [value_request_count_max: max(value.request_count)]" +
"| within d'2020/09/03-12:40:00', d'2020/09/03-12:50:00'\n";
req.setQuery(query);
QueryTimeSeriesResponse res = m.projects().timeSeries().query("projects/MY_PROJECT_NAME", req).execute();
System.out.println(res);
}
使用 within
运算符在查询本身中包含查询开始时间和结束时间。根据 MQL 查询的 google 文档:
within - Specifies the time range of the query output.
