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.
