Wonko

Monitoring and alerting service for all Staples SparX services.

Integration

If you're looking to integrate your service with wonko, see https://github.com/staples-sparx/wonko-client.

How does it work?

• A service integrating with Wonko uses the wonko-client to send metrics to Wonko.
• Wonko reads off designated topics wonko-alerts and wonko-events in the central kafka cluster.
• It sends pager-duty alerts for events coming through wonko-alerts. Each service needs a configured pager-duty endpoint.
• It creates prometheus objects for all metrics and exposes an endpoint per service for prometheus to poll.
• Prometheus polling and alerting is configured independently, outside of wonko.

Histograms

The "stream" type for Prometheus now only uses a histogram. The bucket start/width/count values can be set through the wonko-client's options field. The call will look like: (wonko/stream :halloween-test-2 halloween-attrs 19 :bucket-count 15 :bucket-width 20) This call specifies that there should be 15 buckets of width 20.
