石墨/碳如何获得每秒指标

Question

I've dockerized graphite and am working with this library to get metrics from an Apache Storm topology. I'm getting metrics data, but no matter what I do I can only get data per minute where I really need the points to be per second.

As per this SO post I've set the retention policy to grab data every second. I've also set

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

and

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

in the class that's setting up the topology and the bolt itself, respectively. To my understanding this should cause metrics to be reported every second. What am I missing here? How can I get metrics to be reported every second?

t/y in advance and happy holidays all!

here is my storage-schemas.conf file:

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

Here is my config setup:

Config conf = new Config();
conf.setDebug(false);
conf.put("topology.builtin.metrics.bucket.size.secs", 1);
conf.registerMetricsConsumer(GraphiteMetricsConsumer.class, 4);
conf.put("metrics.reporter.name", "com.verisign.storm.metrics.reporters.graphite.GraphiteReporter");
conf.put("metrics.graphite.host", "127.0.0.1");
conf.put("metrics.graphite.port", "2003");
conf.put("metrics.graphite.prefix", "storm.test");

In order to apply changes in storage-schemas.conf you have to:

• restart carbons
• delete old *.wsp or use whisper-resize.py to apply scheme
• restart carbon-cache
• make sure that DEFAULT_CACHE_DURATION in webapp's local_settings.py is set to 1
• make sure nginx/apache2/uwsgi cache is set up correctly as well, if any

There is more whisper-* tools shipped with graphite . The next you may be interested is whisper-info.py
