Talaiot

Talaiot is an extensible library targeting teams using the Gradle Build System. It records build/task duration helping to understand problems of the build and detecting bottlenecks. For every record, it will add additional information defined by default or custom metrics.

Talaiot is compatible with different systems like InfluxDb, Elasticsearch or RethinkDb. You need to use a Plugin to work with Talaiot. You can use the standard plugin, including all the functionality, or if you have a specific requirement with a individual plugin.

Current available plugins:

Once you have Talaiot integrated you can create dashboards using the build information stored:

What is Talaiot?

"... while some certainly had a defensive purpose, the use of others is not clearly understood. Some believe them to have served the purpose of lookout or signalling towers..."

Talaiot Extension

Metrics

We can include extra information on the build and task tracked data during the build. This information will be added to the default metrics defined.

talaiot {
    metrics {
        // You can add your own custom Metric objects:
        customMetrics(
            MyCustomMetric(),
            // Including some of the provided metrics, individually.
            HostnameMetric()
        )

        // Or define build or task metrics directly:
        customBuildMetrics(
            "kotlinVersion" to $kotlinVersion,
            "javaVersion" to $javaVersion
        )
        customTaskMetrics(
            "customProperty" to $value
        )
    }
}

Read more about it in the Metrics wiki page.

Experimental Provider Metrics

Since version 2.1.0, Talaiot includes an experimental mechanism to define metrics using a provider-based system compatible with Configuration Cache. This approach allows you to lazily evaluate metric values, ensuring that they are resolved only when needed during the build lifecycle. Two entry points are available for executing these providers:

• Initialization phase – executed at the start of the execution phase.
• Finalization phase – executed once the build has finished.

These APIs (initialProviderMetrics and finalProviderMetrics) are marked as experimental and may change in future versions. You can suppress the compiler warning by explicitly opting in with @OptIn(ExperimentalMetricsApi::class).

Example:

metrics {
    initialProviderMetrics(
        "init_memory_metric" to providers.of(GetMemory::class) {}
    )
    finalProviderMetrics(
        "end_memory_metric" to providers.of(GetMemory::class) {}
    )
}

Filters

For every measurement done, Talaiot can filter the tasks tracked to be published.

For every measurement done, Talaiot can completely skip publishing process. These filters affect all publishers:

Example:

 filter {
     tasks {
         excludes = arrayOf("preDebugBuild", "processDebugResources")
     }
     modules {
         excludes = arrayOf(":app")
     }
     threshold {
         minExecutionTime = 10
     }
     build {
         success = true
         requestedTasks {
             includes = arrayOf(":app:assemble.*")
             excludes = arrayOf(":app:generate.*")
         }
     }
 }

IgnoreWhen

We will use IgnoreWhen when we want to ignore publishing the results of the build. One use case is to ignore it when we are building on CI:

talaiot {
    ignoreWhen {
        envName = "CI"
        envValue = "true"
    }
}

Publishers configuration

The Publisher configuration will change depending on the type of plugin you are using. Standard Plugin provides all the different publisher configurations, for example:

talaiot {
    publishers {
        influxDbPublisher {
            dbName = "tracking"
            url = "http://localhost:8086"
            taskMetricName = "task"
            buildMetricName = "build"
        }

    }
    filter {
        threshold {
            minExecutionTime = 10
        }
    }
}

This configuration would be valid for the InfluxDb Plugin.

InfluxDbPublisher

Talaiot will send to the InfluxDb server defined in the configuration the values collected during the execution

For complete list of

• build tags check: https://github.com/cdsap/Talaiot/blob/master/library/core/talaiot/src/main/kotlin/io/github/cdsap/talaiot/metrics/BuildMetrics.kt
• task tags check: https://github.com/cdsap/Talaiot/blob/master/library/core/talaiot/src/main/kotlin/io/github/cdsap/talaiot/metrics/TaskMetrics.kt

If you need to include custom metrics as tags, you need to use the type Custom

Included in: io.github.cdsap.talaiot and io.github.cdsap.talaiot.plugin.influxdb plugins.

InfluxDb2Publisher

Talaiot will send to the InfluxDb (Flux) server defined in the configuration the values collected during the execution

Included in: io.github.cdsap.talaiot and io.github.cdsap.talaiot.plugin.influxdb2 plugins.

RetentionPolicyConfiguration

Retention Policy (RP) describes how long InfluxDB keeps data, how many copies of the data to store in the cluster, and the time range covered by shard groups. RPs are unique per database and along with the measurement and tag set define a series. Since version 1.0.0 we are including by default RP in all the operations included in the publisher. The RetentionPolicyConfiguration includes:

Example of custom RP Configuration:

influxDbPublisher {
  dbName = "xxxxxx"
  url = "xxxxxx"
  retentionPolicyConfiguration {
    name = "customRp"
    duration = "4w"
    shardDuration = "30m"
    replicationFactor = 1
    isDefault = true
  }
}

PushGatewayPublisher

Talaiot will send to the PushGateway server defined in the configuration the values collected during the execution.

Included in: io.github.cdsap.talaiot and io.github.cdsap.talaiot.plugin.pushgateway plugins.

JsonPublisher

Talaiot will Publish the results of the build with a json format .

    publishers {
        jsonPublisher = true

    }

Included in: io.github.cdsap.talaiot and io.github.cdsap.talaiot.plugin.base plugins.

ElasticSearchPublisher

Talaiot will send to the ElasticSearch server defined in the configuration the values collected for tasks and build metrics during the execution in the different workers.

Example:

    publishers {
        elasticSearchPublisher {
          url = "http://localhost:9200"
          taskIndexName = "task"
          buildIndexName = "build"
        }
    }

Included in: io.github.cdsap.talaiot and io.github.cdsap.talaiot.plugin.elasticsearch plugins.

HybridPublisher

This Publisher allows composition over publishers to report tasks and build metrics.

Example:

    publishers {
        hybridPublisher {
            taskPublisher = ElasticSearchPublisherConfiguration().apply {
                url = "http://localhost:9200"
                buildIndexName = "build"
                taskIndexName = "task"
            }

            buildPublisher = InfluxDbPublisherConfiguration().apply {
                dbName = "tracking"
                url = "http://localhost:8086"
                buildMetricName = "build"
                taskMetricName = "task"
            }
        }
    }

In this example we are using InfluxDbPublisher to report build metrics and ElasticSearchPublisher to report task metrics.

Included in: io.github.cdsap.talaiot plugin.

RethinkDbPublisher

Talaiot will send to the RethinkDb server defined in the configuration the values collected during the execution

Included in: io.github.cdsap.talaiot and io.github.cdsap.talaiot.plugin.rethinkdb plugins.

Custom Publishers

Talaiot allows using custom publishers defined by the requirements of your environment, in case you are using another implementation.

talaiot {
    publishers {
        // You can define one or more custom publishers:
        customPublishers(
            MyCustomPublisher()
        )
    }
}

Read more about it in the Publishers wiki page In you are not using additional plugins we recommend to use io.github.cdsap.talaiot.plugin.base.

Sample

Folder sample contains a Gradle project using Talaiot:

cd sample
./gradlew assemble

The project includes examples creating custom publishers, defining metrics using different publishers.

Docker, InfluxDb and Grafana

To have a quick setup to see the possibilities of Talaiot we are providing a Docker image to setup a Grafana + InfluxDb instances(based on this great repo).

Additionally, the Docker image is creating a default database, a provisioned dashboard and the default datasource for InfluxDb. The source is here:

To run the Docker Image:

docker run -d \
  -p 3003:3003 \
  -p 3004:8083 \
  -p 8086:8086 \
  -p 22022:22 \
  -v /var/lib/influxdb \
  -v /var/lib/grafana \
  cdsap/talaiot:latest

You can access to the local instance of Grafana:

http://localhost:3003 root/root

Populating data

If you access to the provisioned Dashboards included in the Docker Image(http://localhost:3003/d/F9jppxQiz/android-task-tracking?orgId=1 and http://localhost:3003/d/WlpZEBRMz/task-cache-info?orgId=1), you will see an empty dashboard like:

To see Talaiot in action, you need to populate the data. We are providing a script to populate data based in the sample project included in the repository. You can execute the script:

bash scripts/populate.sh

The script will download the repository and with the help of Gradle Profiler(https://github.com/gradle/gradle-profiler) will trigger number of builds defined in the scenario file:

assemble {
  tasks = ["clean"]
}
clean_build {
  versions = ["5.1"]
  tasks = ["assemble"]
  gradle-args = ["--parallel"]
  cleanup-tasks = ["clean"]
  run-using = cli
  warm-ups = 20
}

Once is finished you can check the results on the Grafana Dashboard http://localhost:3003/d/F9jppxQiz/android-task-tracking?orgId=1:

Additionally, we have included a new Dashboard to show how to work with the Caching information of the task execution:

http://localhost:3003/d/WlpZEBRMz/task-cache-info?orgId=1

Other Existing Libraries

Talaiot is not a new idea. There are multiple awesome plugins to use to achieve same results:
