The sensu-http-perf-go is a Sensu Check that measures the performance of HTTP requests. And was inspired by the ruby based http-perf check. However that check did not support chanign the TLS timeout, which was a requirement for my use case. So I decided to write my own check in go. As in the ruby version, this check will measure the following metrics: dns_duration, tls_handshake_duration, connect_duration, first_byte_duration, total_request_duration. And it outputs metrics in nagios_perfdata format.
sensu-http-perf-go -u https://example.com sensu-http-perf-go OK: 0.790421s | dns_duration=0.047340, tls_handshake_duration=0.089218, connect_duration=0.049823, first_byte_duration=0.601708, total_request_duration=0.790421
