Memcached,redis Monitoring Detailed

First, Monitoring Collection basis:

Similar throughput, number of cached queries, hit rate, etc.

Second, The main monitoring indicator analysis, through the stats command to collect:

Uptime # #memcached运行时长

Curr_connections # #当前的连接数

Total_connections # #曾经打开的连接总数

Connection_structures # #服务器分配的连接数

Cmd_get # #执行get命令总数

Cmd_set # #执行set命令总数

Get_hits # #get命中次数

Get_misses # #get未命中次数

Bytes_read # #读取字节总数

Bytes_written # #写入字节总数

Bytes # #服务器当前存储占用的内存 (bytes)

Limit_maxbytes # #分配的内存大小 (bytes)

Evictions # #为获取内存而删除的item个数

Third, Zabbix Agent Configuration:

Userparameter=memcached[*], (echo stats; Sleep 1) | Telnet 192.168.10.204 11211 2>&1 | awk '/stat $/{print $NF} '

Key can be read directly from the Web.

Four, Redis Monitoring indicators:

Similar throughput, number of cached queries, hit rate, etc.

Five, mainly through the REDIS-CLI info to monitor:

Uptime_in_days # #启动经过的天数

Connected_clients # #连接的客户端数

Blocked_clients: # #正在等待阻塞命令 (Blpop, Brpop, Brpoplpush) Number of clients

Used_memory_peak_huma: # #reids所用内存的高峰期

Used_memory: # #运行起来使用的内存数

Expired_keys: # #过期的key数量

Evicted_keys: # #删除过期的key数量

Keyspace_misses: # #没命中的key数量

keyspace_hits: # #命中的key数量   

Connected_slaves: # #已连接的从服务器数

Rejected_connections: # #因为超过最大连接数被拒接的请求数量

Six, zabbix_agent configuration file:

Userparameter=redis_stats[*],/usr/local/bin/redis-cli-h 192.168.10.203-p 6379 info|grep $1|cut-d:-f2
