-# Disclaimer
-
-Every module should be compatible with python2 and python3.
-All third party libraries should be installed system-wide or in `python_modules` directory.
-Module configurations are written in YAML and **pyYAML is required**.
-
-Every configuration file must have one of two formats:
-
-- Configuration for only one job:
-
-```yaml
-update_every : 2 # update frequency
-retries : 1 # how many failures in update() is tolerated
-priority : 20000 # where it is shown on dashboard
-
-other_var1 : bla # variables passed to module
-other_var2 : alb
-```
-
-- Configuration for many jobs (ex. mysql):
-
-```yaml
-# module defaults:
-update_every : 2
-retries : 1
-priority : 20000
-
-local: # job name
- update_every : 5 # job update frequency
- other_var1 : some_val # module specific variable
-
-other_job:
- priority : 5 # job position on dashboard
- retries : 20 # job retries
- other_var2 : val # module specific variable
-```
-
-`update_every`, `retries`, and `priority` are always optional.
-
----
-
-The following python.d modules are supported:
-
-# apache
-
-This module will monitor one or more apache servers depending on configuration.
-
-**Requirements:**
- * apache with enabled `mod_status`
-
-It produces the following charts:
-
-1. **Requests** in requests/s
- * requests
-
-2. **Connections**
- * connections
-
-3. **Async Connections**
- * keepalive
- * closing
- * writing
-
-4. **Bandwidth** in kilobytes/s
- * sent
-
-5. **Workers**
- * idle
- * busy
-
-6. **Lifetime Avg. Requests/s** in requests/s
- * requests_sec
-
-7. **Lifetime Avg. Bandwidth/s** in kilobytes/s
- * size_sec
-
-8. **Lifetime Avg. Response Size** in bytes/request
- * size_req
-
-### configuration
-
-Needs only `url` to server's `server-status?auto`
-
-Here is an example for 2 servers:
-
-```yaml
-update_every : 10
-priority : 90100
-
-local:
- url : 'http://localhost/server-status?auto'
- retries : 20
-
-remote:
- url : 'http://www.apache.org/server-status?auto'
- update_every : 5
- retries : 4
-```
-
-Without configuration, module attempts to connect to `http://localhost/server-status?auto`
-
----
-
-# apache_cache
-
-Module monitors apache mod_cache log and produces only one chart:
-
-**cached responses** in percent cached
- * hit
- * miss
- * other
-
-### configuration
-
-Sample:
-
-```yaml
-update_every : 10
-priority : 120000
-retries : 5
-log_path : '/var/log/apache2/cache.log'
-```
-
-If no configuration is given, module will attempt to read log file at `/var/log/apache2/cache.log`
-
----
-
-# beanstalk

- user: 'admin'
- pass: 'password'
- node: 'couchdb@127.0.0.1'
-```
-
-Be sure to specify a correct admin-level username and password.
-
-You may also need to change the `node` name; this should match the value of `-name NODENAME` in your CouchDB's `etc/vm.args` file. Typically this is of the form `couchdb@fully.qualified.domain.name` in a cluster, or `couchdb@127.0.0.1` / `couchdb@localhost` for a single-node server.

-
-This module tries to read from one of two possible locations. On
-initialization, it tries to read the `time_in_state` files provided by
-cpufreq\_stats. If this file does not exist, or doesn't contain valid data, it
-falls back to using the more inaccurate `scaling_cur_freq` file (which only
-represents the **current** CPU frequency, and doesn't account for any state
-changes which happen between updates).
-
-It produces one chart with multiple lines (one line per core).
-

-peer_filter: '(127\..*)|(192\.168\..*)'
-# check for new/changed peers every 60 updates
-peer_rescan: 60
-```
-
-Sample (multiple jobs):

- back into the pool once a response is received (but will release if

-This module provides a pool manager that uses Google App Engine's

- from urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox

- r = http.request('GET', 'https://google.com/')
-
-There are `limitations <https://cloud.google.com/appengine/docs/python/\
-urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
-the best choice for your application. There are three options for using
-urllib3 on Google App Engine:
-
-1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
- cost-effective in many circumstances as long as your usage is within the
- limitations.
-2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
- Sockets also have `limitations and restrictions
- <https://cloud.google.com/appengine/docs/python/sockets/\
- #limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
- To use sockets, be sure to specify the following in your ``app.yaml``::
-
- env_variables:
- GAE_USE_SOCKETS_HTTPLIB : 'true'
-
-3. If you are using `App Engine Flexible
-<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
-:class:`PoolManager` without any configuration or special environment variables.

-SSL with SNI_-support for Python 2. Follow these instructions if you would
-like to verify SSL certificates in Python 2. Note, the default libraries do
-*not* do certificate checking; you need to do additional work to validate
-certificates yourself.
-
-This needs the following packages installed:
-
-* pyOpenSSL (tested with 16.0.0)
-* cryptography (minimum 1.3.4, from pyopenssl)
-* idna (minimum 2.0, from cryptography)
-
-However, pyopenssl depends on cryptography, which depends on idna, so while we
-use all three directly here we end up having relatively few packages required.
-
-You can install them with the following command:
-
- pip install pyopenssl cryptography idna
-
-To activate certificate checking, call
-:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
-before you begin making HTTP requests. This can be done in a ``sitecustomize``
-module, or at any other time before your application begins using ``urllib3``,
-like this::
-
- try:
- import urllib3.contrib.pyopenssl
- urllib3.contrib.pyopenssl.inject_into_urllib3()
- except ImportError:
- pass
-
-Now you can use :mod:`urllib3` as you normally would, and it will support SNI
-when the required modules are installed.
-
-Activating this module also has the positive side effect of disabling SSL/TLS
-compression in Python 2 (see `CRIME attack`_).
-
-If you want to configure the default list of supported cipher suites, you can
-set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

-SecureTranport support for urllib3 via ctypes.

-This makes platform-native TLS available to urllib3 users on macOS without the
-use of a compiler. This is an important feature because the Python Package
-Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL
-that ships with macOS is not capable of doing TLSv1.2. The only way to resolve
-this is to give macOS users an alternative solution to the problem, and that
-solution is to use SecureTransport.
-
-We use ctypes here because this solution must not require a compiler. That's
-because pip is not allowed to require a compiler either.

-This is not intended to be a seriously long-term solution to this problem.
-The hope is that PEP 543 will eventually solve this issue for us, at which
-point we can retire this contrib module. But in the short term, we need to

-
- :param float backoff_factor:
- A backoff factor to apply between attempts after the second try
- (most errors are resolved immediately by a second try without a
- delay). urllib3 will sleep for::
-
- {backoff factor} * (2 ^ ({number of total retries} - 1))
-
- seconds. If the backoff_factor is 0.1, then :func:`.sleep` will sleep
- for [0.0s, 0.2s, 0.4s, ...] between retries. It will never be longer
- than :attr:`Retry.BACKOFF_MAX`.
-
- By default, backoff is disabled (set to 0).
-
- :param bool raise_on_redirect: Whether, if the number of redirects is
- exhausted, to raise a MaxRetryError, or to return a response with a
- response code in the 3xx range.
-
- :param bool raise_on_status: Similar meaning to ``raise_on_redirect``:
- whether we should raise an exception, or return a response,
- if status falls in ``status_forcelist`` range and retries have
- been exhausted.
-
- :param tuple history: The history of the request encountered during
- each call to :meth:`~Retry.increment`. The list is in the order
- the requests occurred. Each list item is of class :class:`RequestHistory`.
-
- :param bool respect_retry_after_header:
- Whether to respect Retry-After header on status codes defined as
- :attr:`Retry.RETRY_AFTER_STATUS_CODES` or not.
