A selection of Nagios plugins to monitor services hosted in OpenTable Mesos.
Basic Nagios/Sensu checks for OpenTable Discovery services.
Run with -h or --help to see command-line argument documentation.
If there is an error parsing command-line arguments, we return with exit code 3 (UNKNOWN) and print the invocation error.
If there is an error reaching Discovery and parsing the announcements for your service, we return with exit code 3 (UNKNOWN).
We log critical and warning statuses related to announcement, and return with exit codes 2 (CRITICAL) and 1 (WARNING) respectively.
By default, otpl-service-check checks your service for health.
If your healthcheck endpoint returns with status code 2xx, this is considered a success. If it returns with 4xx, this is considered a warning (exit code 1). 5xx is considered critical (exit code 2). In the latter two cases, in addition to logging the service status, based on the Content-Type of the response, we log a parsed version of the response body.
All critical statuses, warnings, and successes are logged, and the exit status of the whole process is the worst of the set.
Pulling all announcements from Discovery and then checking each one is inherently racy. If otpl-service-check finds critical errors, it double-checks your service’s announcements. If any of the critical errors are for an announcement that no longer exists, they are downgraded to warnings, and a further warning is emitted indicating that this circumstance occurred.
Note that this does not avoid all race conditions, just a particular class of them.
This is a bit of an abuse of HTTP response codes, but our policy is that this is the simplest and most flexible way to get rich status responses from health check endpoints.
Set up PyPI RC file, .pypirc. E.g.:
[distutils] index-servers = pypi pypitest [pypitest] repository = https://testpypi.python.org/pypi username = cpennello_opentable [pypi] repository = https://pypi.python.org/pypi username = cpennello_opentable
Suppose the version being released is a.b.c.
Create distributions: python setup.py sdist bdist_wheel
Sign distribution files:
for x in dist/*a.b.c*;do gpg --detach-sign -a $x done
Use Twine, uploading to the test repo first. twine upload -r pypitest dist/*a.b.c*
Then to the real repo. twine upload -r pypi dist/*a.b.c*
