“For monitoring, alerting and trending you can use VictorOps, PagerDuty or Sensu. Logging provides an interface for analyzing various machine-generated data, so application-issues detection, as well as resolution, is easier to achieve. For logging, you can use Logotries, Sumo Logic, PaperTrail, Loggly, and Splunk.”
