Alexandra Settle b6896c2400 Fixing broken links
1. Dead link to the HA guide. Added a comment regarding
availability and reliability.
2. Hyper-v link re-routed to Azure instead of Hyper-V.
Updated this so it reflects Hyper-V docs.

Suggestion: Might be worth mentioning which Hyper-V servers
ceilometer actually supports.

Telemetry best practices
~~~~~~~~~~~~~~~~~~~~~~~~
The following are some suggested best practices to follow when deploying
and configuring the Telemetry service.
Data collection
---------------
#. The Telemetry service collects a continuously growing set of data. Not
all the data will be relevant for an administrator to monitor.
- Based on your needs, you can edit the ``polling.yaml`` and
``pipeline.yaml`` configuration files to include select meters to
generate or process
- By default, Telemetry service polls the service APIs every 10
minutes. You can change the polling interval on a per meter basis by
editing the ``polling.yaml`` configuration file.
.. warning::
If the polling interval is too short, it will likely increase the
stress on the service APIs.
#. If polling many resources or at a high frequency, you can add additional
central and compute agents as necessary. The agents are designed to scale
horizontally. For more information refer to the `high availability guide
<https://docs.openstack.org/ha-guide/>`_.
.. note::
The High Availability Guide is a work in progress and is changing
rapidly while testing continues.
