This talk is aimed for engineers operating in distributed environments (or microservices) interested in monitoring exceptions at scale. We introduce the open source project "Periskop", a pull-based exception monitoring service built at SoundCloud and inspired by Prometheus.

• What problems did we encounter with the traditional push-based model for exception monitoring.
  • Thundering herd issues with bad deployments
  • Difficulty navigating large volumes of logs for identifying exceptions
• An alternative pull-based model that scales well with the number of exceptions and instances.
  • Aggregation + sampling for concrete occurrences
  • Limitations and trade-offs (short lived processes and fork-based application servers)
• An implementation of such model into the open source project "Periskop"
  • Initial Development
  • Server and client-libraries
  • Newly added features and roadmap (push-gateway, federation, time series visualization, integrations)
