# ===================== INFORMATION ABOUT THIS TEMPLATE =======================
#
# This is a pnp4nagios template for memcache database check done with check_memcached.pl
#
# The template would graph some status variables returned by check_memcached.pl
# Here is an example of nagios command config:
#
# define command {
# command_name check_memcached
# command_line $USER1$/check_memcached.pl -H $HOSTADDRESS$ -P $ARG1$ -T $ARG2$ -R $ARG3$ -U $ARG4$ -a curr_connections,evictions -w ~,~ -c ~,~ -f -A 'utilization,hitrate,response_time,curr_connections,evictions,cmd_set,bytes_written,curr_items,uptime,rusage_system,get_hits,total_connections,get_misses,bytes,time,connection_structures,total_items,limit_maxbytes,rusage_user,cmd_get,bytes_read,threads,rusage_user_ms,rusage_system_ms,cas_hits,conn_yields,incr_misses,decr_misses,delete_misses,incr_hits,decr_hits,delete_hits,cas_badval,cas_misses,cmd_flush,listen_disabled_num,accepting_conns,pointer_size,pid'
# }
#
# ========================= VERSION HISTORY and TODO ==========================
#
# v0.1 - 03/05/2012 : Initial version of the template created. Includes the following:
# 1. Response Times Graph
# 2. Client Connections Graph
# 3. Network Data Traffic
# 4. Hits and Misses
# 5. Memory Utilization Graph
# 6. Data items
# 7. CPU Usage (this maybe wrong, showing too high)
#
