# ================================ SUMMARY ====================================
#
# File : check_redis.php
# Version : 0.1
# Date : June 01, 2012
# Author : William Leibzon - william@leibzon.org
# Summary : PNP4Nagios template for check_memcached.pl
# Licence : GPL - summary below, full text at http://www.fsf.org/licenses/gpl.txt
#
# This is considered a supplemental file to check_redis.pl plugin and though
# not distributed in unified package it is distributed under the same licencing
# terms (GNU 2.0 license). Any redisribution of this file in modified form must
# reproduce this summary (modified if appropriate) and must either include
# entire GNU license in a package or list URL where it can be found if
# distributed as a single file.
#
# ===================== INFORMATION ABOUT THIS TEMPLATE =======================
#
# This is a pnp4nagios template for redis database check done with check_redis.pl
# that would graph some status variables returned by this plugin.
#
# Unlike most templates this does not care which order variables are returned in
# and will automatically pick the right ones, so you can just use '-A' option
# from the plugin to return all performance variables (though in that case
# your rrd file will lager and contain extra datat that would not be graphed).
#
# Here is an example of nagios command config:
#
# define command {
# command_name check_redis_new
# command_line $USER1$/check_redis.pl -H $HOSTADDRESS$ -p $ARG1$ -T $ARG2$ -R -A -M $_HOSTSYSTEM_MEMORY$ -m $ARG3$ -a $ARG4$ -w $ARG5$ -c $ARG6$ -f -P "$SERVICEPERFDATA$"
# }
#
# Arguments and thresholds are:
# $ARG1 : Port
# $ARG2 : response time thresholds
# $ARG3 : memory utilization thresholds
# $ARG4 : additional variables to be checked
# $ARG5 : warning thresholds for those variables
# $ARG6 : critical thresholds for those variables
#
# define service {
# use prod-service
# hostgroups redishosts
# service_description Redis
# check_command check_redis_new!6379!"1,2"!"80,90"!blocked_clients,connected_clients!50,~!100,~
# }
#
# define host {
# use prod-server
# host_name redis.mynetwork
# address redis.mynetwork
# alias Redis Stat Server
# hostgroups linux,redishosts
# _SYSTEM_MEMORY '8G'
# }
#
# ========================= VERSION HISTORY and TODO ==========================
#
# v0.1 - 05/31/2012 : Initial version of the template created. Includes the following:
# 1. Response Times Graph
# 2. Client Connections Graph
# 3. Hits and Misses
# 4. Keys Graph
# 5. Memory Graph
# 6. CPU Usage (this maybe wrong, showing too high)
#
