API7 Gateway 3.2.16.4

Alert policies can send notification through webhook and email at the same time by utilizing the new Contact Points.

Release Date: 2024-11-01

Features

Send Notification through Email

Alert policies can send notification through webhook and email at the same time by utilizing the new Contact Points. A Contact Point defines a set of email addresses or webhook URLs that can be used by multiple alert policies.

See Trigger Gateway Alerts for instruction.

Existing Webhook Templates will be migrated to new contact points and notifications, ensuring seamless transition and backward compatibility for alert policies.

Limit Count Advanced Plugin

Enhanced the open-source limit count plugin with a sliding window algorithm for more accurate rate limiting.

Exit Transformer Plugin

The exit-transformer plugin supports the customization of gateway responses based on the status codes, headers, and bodies returned from APISIX plugins. When configured as a global plugin, it also supports the response customization when a route that does not exist is requested.

Count Healthy Gateway Instances in a Gateway Group Through Alert Policy

If the number of healthy gateway instances in a gateway group falls below a critical threshold, it indicates potential service disruptions and impacts on traffic handling. This scenario is particularly relevant in Kubernetes deployments, where gateway instances may experience failures or be scaled down unexpectedly.

Create an alert policy for counting healthy gateway instances in a gateway group and send notifications to relevant personnel.

Utilized Expression Matching

Enable Expression Match in a route to match requests based on specific variables for greater precision, similar to nginx. Use expressions in the format [[var, operator, val], [var, operator, val], ...] to define matching criteria. Note that cookie name matching is case-sensitive.

See Expressions and lua-resty-expr for more details.

Security

Added a status interface for self health checks on the data plane. For details, see enable data plane health check for high availability.
