Metrink

Metrink is a metric sink. It records metrics of any type, and then allows you to graph said metrics and apply transformation functions.

Note: This project is VERY much in flux. It is being open source from production code, and as we all know, production ready does NOT mean open source ready.

Building

$ mvn package
# OR
$ mvn package -DskipTests

Settings

To launch any Metrink instance, first create a settings.yml.

# Store metrics in SQL
metrics_database: sql

## Store metrics in Cassandra
#metrics_database: cassandra

# SQL must be configured regardless of metrics_database, because it's used for user meta-data.
sql:
    # H2 Configuration
    driver: org.h2.Driver
    url: jdbc:h2:target/development.db.h2
    username: sa
    password: sa
    
    ## MySQL Configuration
    #url: jdbc:mysql://localhost/metrink
    #username: metrink
    #password: password

# Configure the initial host to connect to for locating the remaining Cassandra instances
cassandra:
    seed: localhost:9160

Launching

Metrink Web:

$ java -jar ./metrink-web/target/metrink-web-*.jar --settings settings.yml

Metrink Collector:

$ java -jar ./metrink-web/target/metrink-collector-*.jar --settings settings.yml server configuration.yml

General notes:

• If running from eclipse, set the working directory to ${workspace_loc:metrink}, otherwise H2 wont share the database between projects.
• To enable debug logging, add -DLOG_LEVEL=DEBUG to the CLI.
• To run wicket in development mode, add -Dwicket.configuration=development to the CLI arguments.
