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 run-time length

Curr_connections # # Current number of connections

Total_connections # # total number of connections ever opened

Connection_structures # # number of connections allocated by the server

Cmd_get # # total number of execute get commands

Cmd_set # # total number of execution set commands

Get_hits # #get Hit Count

get_misses # #get Number of Misses

Bytes_read # # Total Bytes Read

Bytes_written # # Total Bytes Written

Bytes # # memory occupied by the server's current storage (bytes)

Limit_maxbytes # # Allocated memory size (bytes)

Evictions # # the number of items deleted to get memory

Third, Zabbix Agent Configuration:

Userparameter=memcached[*], (echo stats; Sleep 1) | telnet192.168.10.204 11211 2>&1 | awk '/stat $/{print $NF} '

***key you can read it 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 # # number of days to start

connected_clients # # number of clients connected

blocked_clients: # # number of clients waiting for the blocking command (Blpop, Brpop, Brpoplpush)

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
