History
Cédric Jeanneret 52394870c0 Move away from "ss" and drop default verbose mode 
This patch does three main things:
- drop the ultra-verbose output (set -x), adding a new param we can use
  when calling the healthcheck directly
- move away from the "ss" calls and the multiple pipes used to filter
  its output, using "lsof" and native filtering
- rewrite the "ps" call in order to use ps native filters instead of
  piping through grep

These changes should make the healthchecks stronger, and avoid some
weird issues due to the pipes, and lower the amount of logs while
keeping the important information visible.

In order to get verbose mode when running the healthcheck directly, you
can do as follow:

podman exec -u root -ti <container> bash
HEALTHCHECK_DEBUG=1 ./openstack/healthcheck
or
podman -u root -e "HEALTHCHECK_DEBUG=1" <container> /openstack/healthcheck

and enjoy a nice debug output.

Health check commands

The scripts in this directory are meant to implement the container-healthcheck blueprint. They are written to be compatible with the Docker HEALTHCHECK api.

The scripts expect to source /usr/share/tripleo-common/healthcheck/common.sh. If you want to run scripts without installing to that file, you can set the HEALTHCHECKS_DIR environment variable, e.g:

    $ export HEALTHCHECKS_DIR=$PWD
    $ ./heat-api
    {"versions": [{"status": "CURRENT", "id": "v1.0", "links": [{"href": "http://192.168.24.1:8004/v1/", "rel": "self"}]}]}
