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:

Plugin	Description
standard	Contains all the available publishers listed below
base	Talaiot core functionality with Json, Output and Timeline publishers
elasticsearch	Talaiot core functionality with Elasticsearch publisher
influxdb	Talaiot core functionality with Influxdb publisher
influxdb2	Talaiot core functionality with Influxdb2 (Flux) publisher
pushgateway	Talaiot core functionality with Pushgateway publisher
rethinkdb	Talaiot core functionality with Rethinkdb publisher

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

Property	Description
logger	Mode for logging (Silent,Info)
ignoreWhen	Configuration to ignore the execution of Talaiot
generateBuildId	Generation of unique identifier for each execution(disabled by default)
publishers	Configuration to define where to submit the information of the build
metrics	Additional information tracked during the execution of the task
filter	Rules to filter the build or the tasks to be reported

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.

Filters

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

Property	Description
tasks	Configuration used to filter which tasks we want to exclude and include in the execution
module	Configuration used to filter which modules we want to exclude and include in the execution
threshold	Configuration used to define time execution ranges to filter tasks to be reported

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

Property	Description
build.success	Configuration used to skip publishing based on build success.
build.requestedTasks	Configuration used to skip publishing based on what was the requested task.

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

Property	Description
envName	Name of the Property
envValue	Value of the Property

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

Property	Description
dbName	Name of the database
url	Url of the InfluxDb Server
taskMetricName	Name of the metric used for specific task in the execution
buildMetricName	Name of the metric used for the overall information of the build in the execution

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:

Property	Description
name	name of the retentionPolicy(rp). Default rpTalaiot
duration	duration of the rp. Default 30d
shardDuration	the shardDuration. Default 30m
replicationFactor	the replicationFactor of the rp. Default 2
isDefault	if the rp is the default rp for the database or not. Default false

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.

        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"
            }
        }

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.

Example: Analyzing Data provided by Talaiot

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:

• Build Time Tracker by Pascal Hartig(@passy).

• Kuronometer Plugin developed with Scala and FP concepts by Pedro Vicente Gómez Sánchez(@pedrovgs)
