Before Datadog • We used: • munin • growthforecast • cloudwatch • Wanted to centralized management !

After Datadog - Phase1 • OK, we can manage centrally • But...? • We're respecting the free development of engineers ! • Problem that the monitoring setting is leaked out "

Phase2 • Introduce Interferon • Datadog DSL • Well, we can monitor all resources automatically • But...? • Unmaintained in active ! • Can't feel free to mute from Web UI " • Lack of flexibility #

Phase3 • Integrated itamae • Our engineers were used to write chef • Easy to override default settings • It's asynchronous. Feel free to mute from Web UI • Integrated dogaws @takus • Yet another Datadog CloudWatch Integragion • We are used in combination with itamae

Datadog tips • Event collect and easy overlay • Provisioning • Deploy • etc

Datadog tips • Easiness anomary detection • Can't compared over 24hours until quite recently • We request to be able to compare more longer period. Thank Datadog for implementing ! • This is a closed function. If you want to use it, ask Datadog support "

For example • Comapare Kinesis records count EWMA pct_change(median(last_1h), 1w_ago):ewma_20(avg:aws.kinesis.incoming_records{env :production,cost:smartnews} by {name}) > 50 • Compare application warn log change(median(last_1h),1w_ago): sum:app.log.warn{env:production} by {autoscaling_group} > 25

Talk more? • Join our free lunch in Tokyo office ! • Ask me later "

We're hiring! Only two people on Site Reliability Engineering Team ! • εϚχϡʔͷSite Reliability Engineer ืूʂ • http://about.smartnews.com/en/ careers/
