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.
