This is just a small and reasonably self contained tool to check the healthz endpoint of a OC RPC service.
Unfortunately it depends on ZeroMQ's c-library since they are not done with their pure Go solution yet, so both an alpine and a debian version is built.
You can find the latest binaries on the release page.
Example for datastore (port 7246): ./healthz --endpoint=tcp://localhost:7246
Other options
$ ./healthz -h
Usage of ./healthz:
-endpoint string
where to connect (default "tcp://localhost:7200")
-retries uint
how many retries (default 3)
-timeout uint
timeout in ms (default 2000)
