【Azure Developer】Java代码实现获取Azure 资源的指标数据却报错 invalid time interval input

问题描述

在使用 Java 代码调用虚拟机（VM）API获取指标数据时，出现时间格式解析错误。

错误信息：

'{
"code": "BadRequest",
"message": "Detected invalid time interval input: 2024-03-13T13:33:05.123 15:00/2024-03-13T13:48:05.233 15:00, supported Iso 8601 time interval format: (Datetime/Datetime, Datetime/Duration, Duration/Datetime, Duration)"
}'

JAVA 代码：

 static void query() {MetricsQueryClient metricsQueryClient = new MetricsQueryClientBuilder().endpoint("https://management.chinacloudapi.cn").credential(new DefaultAzureCredentialBuilder().build()).buildClient();String resourceId = "<resource id>";Response<MetricsQueryResult> metricsResponse = metricsQueryClient.queryResourceWithResponse(resourceId, Arrays.asList("CpuTime", "Requests"),new MetricsQueryOptions().setGranularity(Duration.ofHours(1)).setTimeInterval(new QueryTimeInterval(OffsetDateTime.now().minusDays(1), OffsetDateTime.now())).setAggregations(Arrays.asList(AggregationType.AVERAGE, AggregationType.COUNT)),Context.NONE);MetricsQueryResult metricsQueryResult = metricsResponse.getValue();for (MetricResult metric : metricsQueryResult.getMetrics()) {System.out.println("Metric name " + metric.getMetricName());for (TimeSeriesElement timeSeriesElement : metric.getTimeSeries()) {System.out.println("Dimensions " + timeSeriesElement.getMetadata());for (MetricValue metricValue : timeSeriesElement.getValues()) {System.out.println(metricValue.getTimeStamp() + " " + metricValue.getTotal());}}}
}

这个会是什么原因导致的呢？

问题解答

添加日志，对比代码生成的时间格式字符串后，发现问题根源于本地执行环境的时区设置相关！

因为 Java SDK中timespan参数仅支持UTC的ZoneOffset。如果本地环境设置为非UTC的时区，例如：export TZ="/usr/share/zoneinfo/Hongkong" 就可以复现此问题。

鉴于此种情况，如果不修改本地电脑环境的情况下，可以在代码中进行指定时间为UTC时区。

添加代码：ZoneOffset zoneOffsetUTC = ZoneOffset.ofHours(0);，然后在设置 setTimeInterval 中指定时区 OffsetDateTime.now().withOffsetSameInstant(zoneOffsetUTC)。这样就可以解决时间格式因时区不同而产生的问题！

修改后的代码为：

 static void query() {MetricsQueryClient metricsQueryClient = new MetricsQueryClientBuilder().endpoint("https://management.chinacloudapi.cn").credential(new DefaultAzureCredentialBuilder().build()).buildClient();String resourceId = "<resource id>";    ZoneOffset zoneOffsetUTC = ZoneOffset.ofHours(0);
    Response<MetricsQueryResult> metricsResponse = metricsQueryClient.queryResourceWithResponse(resourceId, Arrays.asList("CpuTime", "Requests"),new MetricsQueryOptions().setGranularity(Duration.ofHours(1)).setTimeInterval(new QueryTimeInterval(OffsetDateTime.now().minusDays(1).withOffsetSameInstant(zoneOffsetUTC), OffsetDateTime.now().withOffsetSameInstant(zoneOffsetUTC))).setAggregations(Arrays.asList(AggregationType.AVERAGE, AggregationType.COUNT)),Context.NONE);MetricsQueryResult metricsQueryResult = metricsResponse.getValue();for (MetricResult metric : metricsQueryResult.getMetrics()) {System.out.println("Metric name " + metric.getMetricName());for (TimeSeriesElement timeSeriesElement : metric.getTimeSeries()) {System.out.println("Dimensions " + timeSeriesElement.getMetadata());for (MetricValue metricValue : timeSeriesElement.getValues()) {System.out.println(metricValue.getTimeStamp() + " " + metricValue.getTotal());}}}
}
