Improving Observability of Subscriptions and Event Triggers in Hasura – a Golden Signals approach

The blog discusses the improvements made by Hasura to enhance the observability of subscriptions and event triggers in its GraphQL engine. Drawing inspiration from Google's Golden Signals monitoring approach, Hasura incorporates latency, traffic, errors, and saturation into subscription observability. This allows developers to monitor and debug their Hasura-based applications effectively. Event triggers in Hasura enable reacting to database events and invoking webhooks. Monitoring metrics helps identify saturation and take necessary actions such as increasing the number of HTTP workers or scaling the Hasura instance. The blog also provides instructions on how to try out the observability setup with self-hosted Enterprise Edition version and export observability data from the Hasura cloud.
