edgible connectivity

Verify that an application’s hostname is reachable from this machine, and how long the round-trip takes.

Terminal window
edgible connectivity test --application my-app
edgible connectivity test --host api.example.com --port 443
edgible connectivity test --host my-host --port 443 --timeout 10000
FlagDescription
-a, --application <name>Application to test (looks up its hostname).
-h, --host <host>Hostname to test directly.
-p, --port <n>Port to test.
-t, --timeout <ms>Per-attempt timeout in milliseconds. Default 5000.

The test does a DNS lookup, a TCP connect, and (for HTTPS) a TLS handshake, reporting timing for each step. A failed test surfaces which step failed — DNS, TCP, or TLS — which is the signal you usually want when debugging a flaky deploy.
