Find Dropwizard metrics

org.openrewrite.micrometer.dropwizard.FindDropwizardMetrics

Find uses of Dropwizard metrics that could be converted to a more modern metrics instrumentation library.

Recipe source​

GitHub: FindDropwizardMetrics.java, Issue Tracker, Code Genome Project

This recipe is available under the Moderne Source Available License. Moderne customers can download precompiled artifacts from The Code Genome Project. For non-commercial use you can build the artifact from source locally.

Example​

Before​
import com.codahale.metrics.MetricRegistry;

class Test {
   void instrument(MetricRegistry registry) {
       registry.counter("my.counter");
       registry.gauge("my.gauge");
   }
}
After​
import com.codahale.metrics.MetricRegistry;

class Test {
   void instrument(MetricRegistry registry) {
       /*~~(Counter)~~>*/registry.counter("my.counter");
       /*~~(Gauge)~~>*/registry.gauge("my.gauge");
   }
}

Usage​

This recipe has no required configuration options. It can be activated by adding a dependency on `org.openrewrite.recipe:rewrite-micrometer` in your build file or by running a shell command (in which case no build changes are needed):

OpenRewrite artifacts, including the Maven and Gradle plugins themselves, are distributed through the Code Genome Project repository (https://artifacts.codegenomeproject.org/maven), which requires authentication. Sign in to the Code Genome Project to create a download token; your build authenticates with the email or username you signed in with, plus that token as the password. See the quickstart guide for details.

  1. Put your Code Genome Project credentials in ~/.gradle/gradle.properties, so that they are not committed alongside your build:
    ~/.gradle/gradle.properties
    codeGenomeUsername=you@example.com
    codeGenomeToken=your-download-token
  2. Add the Code Genome Project repository to your settings.gradle file, so that the plugin itself can be resolved:
    settings.gradle
    pluginManagement {
        repositories {
            maven {
                url = "https://artifacts.codegenomeproject.org/maven"
                credentials {
                    username = providers.gradleProperty("codeGenomeUsername").get()
                    password = providers.gradleProperty("codeGenomeToken").get()
                }
            }
            // Keep the portal for any other plugins your build applies
            gradlePluginPortal()
        }
    }
  3. Add the following to your build.gradle file:
    build.gradle
    plugins {
        id("org.openrewrite.rewrite") version("latest.release")
    }

    rewrite {
        activeRecipe("org.openrewrite.micrometer.dropwizard.FindDropwizardMetrics")
        setExportDatatables(true)
    }

    repositories {
        mavenCentral()
        maven {
            url = "https://artifacts.codegenomeproject.org/maven"
            credentials {
                username = providers.gradleProperty("codeGenomeUsername").get()
                password = providers.gradleProperty("codeGenomeToken").get()
            }
        }
    }

    dependencies {
        rewrite("org.openrewrite.recipe:rewrite-micrometer:0.30.2")
    }
  4. Run gradle rewriteRun to run the recipe.
