3. Expectations ‣Common Data Types ‣Using your Data ‣Features of Data

   Stores ‣Popular Data Stores

4. Types of DevOps-y Data

5. Administrative & Meta-Data ‣ Inventory ‣ Hardware ‣ Software ‣

   Builds or Roles ‣ Services ‣ Users and Groups ‣ Employee/Contractor ‣ Managers ‣ ACLs

6. Monitoring ‣ State ‣ OK / NOT OK ‣ UP

   / DOWN ‣ Package Version ‣ Time Series ‣ Counter ‣ Rate ‣ Statistical Summaries

7. Events ‣ State Changes ‣ Package Updated ‣ Service Stopped

   ‣ System Events ‣ Syslog Message ‣ SNMP Traps ‣ Application Events ‣ Access ‣ Errors ‣ Traces

8. Deving and Oping Your Data

9. Monitoring and Metrics

10. -Nicole Forsgren - Monitorama PDX 2016 How Metrics Shape Your

    Culture “Metrics are your culture.”

11. "How Metrics Shape Your Culture" • You can't improve what

    you don't measure • Always measure things that matter • Things measured are things managed • Metrics can be gamed • Metrics inform incenticves • Not everything that can be counted counts • Hard to measure doesn't mean it isn't worth measuring

12. ... and that's probably O.K. All of your monitoring is

    probably wrong.

13. Alerting ‣ Disrupting People's Lives at 95% Disk Full ‣

    Thresholds -> Change Detection ‣ State Change Thresholds

14. Automation ‣ Can a Machine read my data? ‣ Autoscale

    ‣ Trend detection ‣ Service Level Roll Ups in Alerting ‣ Reporting

15. Capacity Planning ‣ Predicting System Stress Levels ‣ Make Intelligent

    Projections ‣ Test those predictions

16. Exploration

17. Attractive Features

18. Open and Extensible ‣ Integrations with other projects ‣ Open

    API ‣ Good Documentation ‣ Modular / Plugin Structute ‣ Community

19. Reliability vs. Performance

20. Retention ‣ How easy is it to age data off?

    ‣ What regulations of laws apply to the data? ‣ Expectations from: ‣ Customers ‣ Employees ‣ Managers ‣ Peers ‣ Legal

21. Privacy and Security ‣ What do you keep on your

    users in your ops data? ‣ Who might come calling for it? ‣ How comfortable are you handing it over to Trump? ‣ Anyone hear about MongoDB? ‣ Can the store provide security?

22. Places People Stick DevOps Datas

23. ‣ Large Community ‣ Forks and Oracle ‣ Performance First

    ‣ SQL Interface ‣ Limited Data Types ‣ Web > BI ‣ Suitable for Administrative Data

24. ‣ Large Community ‣ Reliability First ‣ Open and Extensible

    ‣ PGXN ‣ CitusData ‣ GreenPlum ‣ EnterpriseDB ‣ Native Support for IP Addresses ‣ Extensible Data Types ‣ Suitable for Administrative Data

25. ‣ Large Community ‣ Interchangeable Components, ala, MicroServices ‣ Simple

    API ‣ Rampant Open Source Adoption ‣ Scalable ‣ Compatibility ‣ Grafana, Statsd, Riemann, Bosun, Cabot, Seyren ‣ etc., etc., ‣ Suitable for Time Series Data ‣ Smallest Resolution: seconds

26. security.logging.indexer.*.total Metrics: Wildcards

27. sumSeries(security.logging.indexer.*.total) Combining Metrics

28. alias(sumSeries(security.logging.indexer.*.total),”Today") alias( timeShift( sumSeries(security.logging.indexer.*.total), “7d"), "Last Week") Comparing Metrics

29. alias(alpha(color(areaBetween( holtWintersConfidenceBands( maxSeries(general.es.*.jvm.mem.heap_used_bytes) ) ),“gray"),0.1),"Hot Winter Confidence Bands”) color(alias( maxSeries(general.es.*.jvm.mem.heap_used_bytes),

    "Max Heap Size"),"red") Advanced Tricks

30. ‣ Metrics 2.0 ‣ Hadoop / Hbase backed ‣ SQL-like

    Language ‣ Zero Data Loss ‣ Compatibility ‣ Carbon, Grafana, Statsd, Riemann, Bosun ‣ Suitable for Time Series Data ‣ Smallest Resolution: milliseconds

31. ‣ Metrics 2.0 ‣ SQL-like Language ‣ Zero Data Loss

    ‣ Compatibility ‣ Carbon, Grafana, Statsd, Riemann, Bosun ‣ Suitable for Time Series Data ‣ Smallest Resolution: nanoseconds

32. ‣ Well Documented API ‣ Many Open Source Integrations ‣

    Lucene backed text search ‣ Scalable ‣ "Jepsen ElasticSearch" re:CAP

33. Web Attacks Scanners

34. Slow Pages
