App Nutcracker

Overview

Template for collecting nutcracker (twemproxy) metrics.

By default template use system.run to collect metrics from http://localhost:22222 (can be altered via macro) via zabbix-agent, but it can be changed to userparameter or http agent if remote commands are forbidden.

Some of the features:

Pool and server discovery.
Single request for LLD and metrics.
Minimum host dependencies - only curl needed if system.run used. No host dependencies with http agent.
No host scripts, utilizing Zabbix features: dependent items and JavaScript preprocessing.
