Can we assign excellent engineers to every positions?
No, probably
The answer is
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

Summary
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
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
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);
Trace methods & queries
Record Deployments
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

NewRelic Insights
Query to custom metrics via NRQL SmartNews seems top 10 user of Insights
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
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
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]"]
BTW, What is dd-agent?

Built-in Integrations
Setup MySQL Monitor
# Edit conf.d/mysql.yaml
instances:
- server: localhost
user: datadog
pass: xxxxxxxx
tags:
- dbtype:master
options:
replication: 0
Correlate metrics w/ deployment
New Relic Integration
sum:apache.status_2xx_count{role:web} by {env}
EC2 Classic
VPC
Tag-based flexible visualization
Migrate from EC2 Classic to VPC with Route53
role = web env = classic
role = web env = vpc
Provision clusters with Chef
role = web env = classic
role = web env = vpc
Aggregate metrics with 'env' tag
Check clusters by Host Maps

Build your own dashboards
PagerDuty Integration
Only pager for related teams (members)
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

• Presto with Prestogres
• non-engineer can create dashboard w/o SQL
How to create charts?1. Build a query to data source (drag & drop / SQL)
2. Modify data (filter、sort、add column)
3. Visualise it (table, pie chart, bar chart)
Connecting to Presto
