+
+It produces:
+
+* frequency
+* last offset
+* RMS offset
+* residual freq
+* root delay
+* root dispersion
+* skew
+* system time
+
+**Requirements:**
+Verify that user netdata can execute `chronyc tracking`. If necessary, update `/etc/chrony.conf`, `cmdallow`.
+
+### Configuration
+
+Sample:
+```yaml
+# data collection frequency:
+update_every: 1
+
+# chrony query command:
+local:
+ command: 'chronyc -n tracking'
+```
+
+---

# cpufreq
This module shows the current CPU frequency as set by the cpufreq kernel

+ HTTP request method (such as GET, POST, PUT, etc.)

+ :param body:
+ Data to send in the request body (useful for creating
+ POST requests, see HTTPConnectionPool.post_url for
+ more convenience).
+
+ :param headers:
+ Dictionary of custom headers to send, such as User-Agent,
+ If-None-Match, etc. If None, pool headers are used. If provided,
+ these headers completely replace any pool-specific headers.

+ :param retries:
+ Configure the number of retries to allow before raising a

+
+ Pass ``None`` to retry until you receive a response. Pass a
+ :class:`~urllib3.util.retry.Retry` object for fine-grained control
+ over different types of retries.
+ Pass an integer number to retry connection errors that many times,
+ but no other types of errors. Pass zero to never retry.
+
+ If ``False``, then retries are disabled and any exception is raised
+ immediately. Also, instead of raising a MaxRetryError on redirects,
+ the redirect response will be returned.
+
+ :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
+
+ :param redirect:
+ If True, automatically handle redirects (status codes 301, 302,
+ 303, 307, 308). Each redirect counts as a retry. Disabling retries
+ will disable redirect, too.
+
+ :param assert_same_host:
+ If ``True``, will make sure that the host of the pool requests is
+ consistent else will raise HostChangedError. When False, you can
+ use the pool on an HTTP proxy and request foreign hosts.

+ :param timeout:
+ If specified, overrides the default timeout for this one
+ request. It may be a float (in seconds) or an instance of
+ :class:`urllib3.util.Timeout`.
+
+ :param pool_timeout:
+ If set and the pool is set to block=True, then this method will
+ block for ``pool_timeout`` seconds and raise EmptyPoolError if no
+ connection is available within the time period.
+
+ :param release_conn:
+ If False, then the urlopen call will not release the connection
+ back into the pool once a response is received (but will release if
+ you read the entire contents of the response such as when
+ `preload_content=True`). This is useful if you're not preloading
+ the response's content immediately. You will need to call
+ ``r.release_conn()`` on the response ``r`` to return the connection
+ back into the pool. If None, it takes the value of
+ ``response_kw.get('preload_content', True)``.
+
+ :param chunked:
+ If True, urllib3 will send the body using chunked transfer
+ encoding. Otherwise, urllib3 will send the body using the standard
+ content-length form. Defaults to False.
+
+ :param int body_pos:
+ Position to seek to in file-like body in the event of a retry or
+ redirect. Typically this won't need to be set because urllib3 will
+ auto-populate the value when needed.

+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
+solve the impending tire fire that is Python on Mac without this kind of
+contrib module. So...here we are.
+
+To use this module, simply import and inject it::
+
+ import urllib3.contrib.securetransport
+ urllib3.contrib.securetransport.inject_into_urllib3()
+
+Happy TLSing!

+
+ Defaults to None.
+
+ :type total: integer, float, or None
+
+ :param connect:
+ The maximum amount of time to wait for a connection attempt to a server
+ to succeed. Omitting the parameter will default the connect timeout to
+ the system default, probably `the global default timeout in socket.py
+ <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.

+
+ Many factors can affect the total amount of time for urllib3 to return
+ an HTTP response.
+
+ For example, Python's DNS resolver does not obey the timeout specified
+ on the socket. Other factors that can affect total request time include
+ high CPU load, high swap, the program running at a low priority level,
+ or other behaviors.
+
+ In addition, the read and total timeouts only measure the time between
+ read operations on the socket connecting the client and the server,
+ not the total amount of time for the request to return a complete
+ response. For most requests, the timeout is raised because the server
+ has not sent the first byte in the specified time. This is not always
+ the case; if a server streams one byte every fifteen seconds, a timeout
+ of 20 seconds will not trigger, even though the request will take
+ several minutes to complete.
+
+ If your goal is to cut off any request after a set amount of wall clock
+ time, consider having a second "watcher" thread to cut off a slow
