Remap Stats Plugin

This global plugin adds remap stats to the Traffic Server statistics.

Installation

Add the following line to 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:

--post-remap-host, -P: Whether to use the post-remap host in the URL, instead of the pristine client URL.

--persistent, -p: Whether to use persistent stats.

Options in the code:

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 Accessing Statistics.
