Zabbix监控memcache示例

一、创建memcached-tool脚本

参见http://www.linuxidc.com/Linux/2014-08/105157.htm

1	mkdir  /scripts  &&  cd  /scripts  && vim memcache-tool.pl

1 2	将脚本copy进入memcache-tool.pl chmod  +x  /scripts/memcache-tool .pl

二、用脚本查看memcache的各类统计数据

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

/scripts/memcache-tool .pl 127.0.0.1:11211 stats #127.0.0.1:11211   Field       Value           accepting_conns           1               auth_cmds           0              auth_errors           0                  bytes           0               bytes_read          94               bytes_written        5261              cas_badval           0                cas_hits           0               cas_misses           0                cmd_flush           0                 cmd_get           0                 cmd_set           0                cmd_touch           0              conn_yields           0        connection_structures          11           curr_connections          10               curr_items           0                decr_hits           0              decr_misses           0              delete_hits           0             delete_misses           0          evicted_unfetched           0                evictions           0           expired_unfetched           0                 get_hits           0                get_misses           0                   hash_bytes      524288           hash_is_expanding           0            hash_power_level          16                incr_hits           0               incr_misses           0                 libevent        2.0.21-stable             limit_maxbytes        134217728          listen_disabled_num           0                      pid       10459               pointer_size          64                 reclaimed           0               reserved_fds          20                rusage_system    0.121024                 rusage_user    0.045384                 threads           4                     time       1426727521           total_connections          18               total_items           0                touch_hits           0              touch_misses           0                    uptime        2574                   version      1.4.15

三、在zabbix_agent.conf中自定义UserParameter

修改以下的参数：

1 2	UnsafeUserParameters=1 UserParameter=MemcacheStats[*], /scripts/memcache-tool .pl 127.0.0.1:11211 stats| grep  $1 | awk  '{print $NF}'

然后重启zabbix_agent进程

四、在zabbix中添加item

例如，添加当前“curr_connections”

保存即可。

*如果出现“Not supported by Zabbix Agent”的错误，

通过下面的命令得到详细的信息：

1	zabbix_agent -t MemcacheStats[curr_connections]]

或者修改zabbix_server.conf中的

1	Timeout=3   #将这个值调整的大一点
