In the absence of stats_tags to handle this pattern, when we pass "ingress_upstream.$port" as the stat_prefix, Envoy splits up that prefix and makes the port a part of the metric name. For example: - stat_prefix: ingress_upstream.8080 This leads to metric names like envoy_http_8080_no_route. Changing the stat_prefix to ingress_upstream_80880 yields the expected metric names such as envoy_http_no_route. Note that we don't encode the destination's name/ns/dc in this stat_prefix because for HTTP services ingress gateways use a single filter chain. Only cluster metrics are available on a per-upstream basis. |

Consul 
- Website: https://www.consul.io
- Tutorials: HashiCorp Learn
- Forum: Discuss
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Consul provides several key features:
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Mesh/Service Segmentation - Consul Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections without being aware of Connect at all.
-
Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
-
Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
-
Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.
Consul runs on Linux, Mac OS X, FreeBSD, Solaris, and Windows. A commercial version called Consul Enterprise is also available.
Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
