Health Checks

Mission control provides the ability to define and run periodic health checks against services, infrastructure and applications.

Synthetic

Synthetic checks are periodically run by canary checker to directly test services/applications by generating requests using http, sql, mongo, redis, ldap, etc.

Passive

Passive checks consolidate alerts from monitoring systems like Prometheus, Datadog, Dynatrace, CloudWatch and ElasticSearch

Infrastructure

Active infrastructure checks provision infrastructure (e.g. EC2 Instances, Kubernetes Pods) and then run synthetic checks against them to verify the ability to provision infrastructure. This allows detecting issues in infrastructure provisioning processes.

Integration

Integration checks run automated test suites using tools like Playwright, JUnit, Newman and K6 to validate end-to-end functionality across services and infrastructure.

info

Under the hood health checks are implemented using the open-source flanksource/canary-checker project

Metrics Exporter​

In addition to returning a pass/fail status, health checks can export metrics to Prometheus, replacing the need for many custom prometheus exporters.

Scripting​

Evaluate the health of checks using scripts in CEL, Javascript or Go Templating. Scripts can also be used to filter and transform alerts from external systems.

Dashboard​

Dashboard

The health checks page provides a high level view of the overall health of all services, infrastructure and applications. It surfaces recent failures and provides a high level latency and reliability metrics.

Topology

Health checks can be associated with components in a topology and will then show up in the topology card:

Prometheus

Prometheus metrics are exposed from health checks to provide high level visibility into latency, error rates and other metrics. This allows monitoring the health of services and applications using existing Prometheus alerts and Grafana dashboards.

Synthetic

Synthetic checks are periodically run by canary checker to directly test services/applications by generating requests using http, sql, mongo, redis, ldap, etc.
