  4. Efficient Ads System Document Classification Site Reliability Engineering High Performance

    API Server News Crawler Realtime Ranking Algorithm Data Management Platform UI/UX
  5. Why SaaS? • Solves specific issues for us • monitoring,

    alerting, visualising etc... • Less bootstrap process • tiny setup process (a java agent, a chef recipe etc...) • built-in user friendly web Interface • No dedicated person is needed to develop/operate • experts in an area do it well • easy to manage with programable API
  6. NewRelic • (Application) Monitoring as a Service • easy setup

    for popular language (e.g. Java) • add method traces by annotation • trace SQL queries automatically • records deployments
  7. Setup for Tomcat • deploy newrelic archives to $CATALINA_HOME •

    edit newrelic.yml • application name • add -javaagent • $CATALINA_HOME/newrelic/newrelic.jar • add environment if necessary • -Dnewrelic.environment=xxx
  8. Customize for each Apps # add method tracer @Trace(metricName="API/yourMethod", dispatcher=true)

    public Response yourMethod() { ... ... ... } # add custom metric MetricAggregator aggregator = NewRelic.getAgent().getMetricAggregator(); aggregator.recordMetric(key, value); # record exception NewRelic.noticeError(ex);
  9. from fabric.api run from fabric.decorators import runs_once, parallel @parallel @task

    def deploy(): do_your_task() notify() @runs_once def notify(): ver = release_version() run("java -jar newrelic.jar deployment --appname=xxxx --revision=%s" % ver) Record deployment by fabric https://docs.newrelic.com/docs/agents/java-agent/instrumentation/recording-deployments-java-agent
  10. What's great? • Developer can monitor their own app by

    themselves • adding custom tracer, custom metrics • Don't have to prepare profiler for each language • Java, Scala, Ruby, (Golang), etc... • suit for Microservices
  11. Datadog • (System) Monitoring as a Service • easy to

    setup with Chef • 100+ built in integration (AWS, MySQL, Docker...) • correlate metrics with events • tag-based flexible visualization • build your own interactive dashboards
  12. Setup dd-agent with Chef # Install cookbook knife cookbook site

    install datadog # Set Datadog-specific attributes node.default['datadog']['api_key'] = "xxxxxxxxxx" # Add a recipe in your run list "run_list": ["recipe[datadog::dd-agent]"]
  13. Setup MySQL Monitor # Edit conf.d/mysql.yaml instances: - server: localhost

    user: datadog pass: xxxxxxxx tags: - dbtype:master options: replication: 0
  14. role = web env = classic role = web env

    = vpc Provision clusters with Chef
  15. role = web env = classic role = web env

    = vpc Aggregate metrics with 'env' tag
  16. What's great? • No dedicated Ops required for system monitoring

    • chef cookbook & built-in integration • customisable dashboard for each developers • Find the root cause quickly • gather all of metrics/events/alerting at one place • tag-based flexible visualization • correlating metrics & events
  17. Chartio • Dashboard as a Service • create beautiful dashboards

    • provide connectors to various data sources • MySQL, Redshift, Google Analytics, BigQuery, etc... • Presto with Prestogres • non-engineer can create dashboard w/o SQL
  18. How to create charts? 1. Build a query to data

    source (drag & drop / SQL) 2. Modify data (filterɺsortɺadd column) 3. Visualise it (table, pie chart, bar chart)
  19. Join BigQuery & MySQL Layer1 BigQuery Result article_id country pv
