Graphite / Carbon如何获得每秒指标

Question

我dockerized graphite正在与this library合作，以获取Apache Storm拓扑中的指标。我正在获取指标数据，但无论我做什么，我只能每分钟获得数据，而我真正需要每秒点数。

根据this SO post，我将保留政策设置为每秒抓取一次数据。我也设置了

MediaStore.EXTRA_OUTPUT

和

conf.put("topology.builtin.metrics.bucket.size.secs", 1);

分别在设置拓扑和螺栓本身的类中。根据我的理解，这应该导致每秒报告指标。我在这里错过了什么？如何获得每秒报告的指标？

提前和节日快乐！

这是我的storage-schemas.conf文件：

void initMetrics(TopologyContext context) {
    messageCountMetric = new CountMetric();
    context.registerMetric("digest_count", messageCountMetric, 1);
}

这是我的配置设置：

root@cdd13a16103a:/etc/carbon# cat storage-schemas.conf 
# Schema definitions for Whisper files. Entries are scanned in order,
# and first match wins. This file is scanned for changes every 60 seconds.
#
#  [name]
#  pattern = regex
#  retentions = timePerPoint:timeToStore, timePerPoint:timeToStore, ...

# Carbon's internal metrics. This entry should match what is specified in
# CARBON_METRIC_PREFIX and CARBON_METRIC_INTERVAL settings
[carbon]
pattern = ^carbon\.
retentions = 1s:6h,1min:7d,10min:5y


[default_1min_for_1day]
pattern = .*
retentions = 1s:6h,1min:7d,10min:5y


[test]
pattern = ^test.
retentions = 1s:6h,1min:7d,10min:5y

[storm]
pattern = ^storm.
retentions = 1s:6h,1min:7d,10min:5y

要在storage-schemas.conf中应用更改，您必须：

• 重新启动碳素
• 删除旧* .wsp或使用whisper-resize.py应用方案
• 重启碳缓存
• 确保webapp的local_settings.py中的DEFAULT_CACHE_DURATION设置为1
• 确保nginx / apache2 / uwsgi缓存也正确设置，如果有的话

还有更多whisper-* tools shipped with graphite。您可能感兴趣的是whisper-info.py
