This global plugin adds remap stats to the Traffic Server statistics.
Installation
============
Add the following line to :file:`plugin.config`::
remap_stats.so
In this case, the plugin will use the default behaviour:
- Create stats for all remap stats
- URLs will be the pristine URL from the client
- Stats will not be persistent
Options
=======
Flags and options are:
.. option:: --post-remap-host, -P
Whether to use the post-remap host in the URL, instead of the pristine client URL.
.. option:: --persistent, -p
Whether to use persistent stats.
Options in the code:
.. c:macro:: MAX_STAT_LENGTH
The maximum length of any stat name. Since stat names include the remap FQDN, this affects the maximum FQDN length that can be included in the stat.
Stats
=====
The following stats are added to the Traffic Server statistics, for every remap rule::
plugin.remap_stats.<fqdn>.in_bytes
plugin.remap_stats.<fqdn>.out_bytes
plugin.remap_stats.<fqdn>.status_2xx
plugin.remap_stats.<fqdn>.status_3xx
plugin.remap_stats.<fqdn>.status_4xx
plugin.remap_stats.<fqdn>.status_5xx
plugin.remap_stats.<fqdn>.status_unknown
The ``<fqdn>`` will be either the pristine client URL or the remapped URL, depending on whether ``--post-remap-host`` is set.
All stat values are integers.
These stats are available anywhere Traffic Server statistics can be viewed, such as the ``stats_over_http`` plugin and ``traffic_ctl metric get``. See :ref:`admin-stats-accessing`.
