How to show Dropwizard active requests in logs

阅读更多关于 How to show Dropwizard active requests in logs

问题 This question is related to the one I ask here. I'm trying to log the number of active requests being made to my Dropwizard application every 10 minutes. The idea is to track usage of the app so it can get the proper support. In doing this, I'm trying to expose the dropwizard metrics to the logs. For testing purposes, I've made the following code: @GET @Path("/metrics") public MetricRegistry provideMetrics() { MetricRegistry metrics = new MetricRegistry(); metrics.register("io.dropwizard

Using MetricsServlet to fetch metrics in Cassandra

阅读更多关于 Using MetricsServlet to fetch metrics in Cassandra

问题 I want to fetch various metrics like read/write latency, disk utilisation etc. of each of my Cassandra nodes(without using JMX) as a JSON object. It seems to me that MetricsServlet, can do exactly that. However, I'm still not able to figure out, what all do I need to do in order to use it(metrics-servlets does not come with Cassandra). I'll appreciate if I can get some advice/sample code(for fetching any metric). 回答1: Cassandra is not a java web server, it doesnt support servlets. You would

Trying to integrate Coda Hale Metrics in spring boot, not seing the metrics in /metrics

阅读更多关于 Trying to integrate Coda Hale Metrics in spring boot, not seing the metrics in /metrics

问题 I have followed the indication that adding the coda hale metrics library into the classpath would automatically autoconfigure the metrics. That works, I get the injected metricRegistry bean. However, how to I expose these new metrics in the /metrics endpoint? Thanks! 回答1: That's not the way it's supposed to work. Codahale has some metric types that do not map to Spring Boot ones, so you are supposed to use the Codahale native APIs for reporting once you start collecting metrics that way. Boot

问题 How do I collect these metrics on a console (Spark Shell or Spark submit job) right after the task or job is done. We are using Spark to load data from Mysql to Cassandra and it is quite huge (ex: ~200 GB and 600M rows). When the task the done, we want to verify how many rows exactly did spark process? We can get the number from Spark UI, but how can we retrieve that number ("Output Records Written") from spark shell or in spark-submit job. Sample Command to load from Mysql to Cassandra. val

How can I reset timer of dropwizard metrics?

阅读更多关于 How can I reset timer of dropwizard metrics?

问题 We are processing messages that comes in periodically. We use codahale dropwizard metrics' "Timer" for measuring the time it takes to process them. I found someone had the same issue here: "problem with exponentially decaying reservoir is that if no new data comes in, it will keep on giving the same numbers all the times. For example, let say you update a timer with 5 and 7 (then don't put anything at all) , then no matter when you see (even after x hours), timer will still show the average

Codahale Metrics: using @Timed metrics annotation in plain Java

I am trying to add metrics to a plain Java application using codahale metrics. I'd like to use the @Timed annotation, but it is unclear to me which MetricRegistry it uses, or how to tell it which MetricRegistry to use. The application is a plain Java 8 application, built with Maven 3, no Spring, no Hibernate. I can not find any documentation on how to implement @Timed in the dropwizard documentation: https://dropwizard.github.io/metrics/3.1.0/manual/ I've added these dependencies: <dependency> <groupId>io.dropwizard.metrics</groupId> <artifactId>metrics-core</artifactId> <version>3.1.0<
