Zabbix monitoring Redis Python3 scripts

One: Install the Redis-python module

WGE thttps://pypi.python.org/packages/source/r/redis/redis-2.9.1.tar.gz

Tar XF redis-2.9.1.tar.gz

CD redis-2.9.1

Python setup.py Install

Two: Configuration Zabbix

(1) Put the zabbix-redis.py into the/usr/local/zabbix/etc/scripts directory

(2) Change zabbix_agentd.conf Include${dir}/zabbix. Userparameter

(3) Restart Zabbix_agentd

Killall Zabbix_agentd

/usr/local/zabbix/sbin/zabbix_agentd-c/usr/local/zabbix/etc/zabbix_agentd.conf

Second: The main monitoring projects include

The client queries the key value hits and misses to calculate the hit ratio

Number of client connections for the current Redis instance

Number of clients currently in a blocked state

How often the client executes commands per second

Number of connections from the library

Memory usage Status

Three: Specific parameters explained

Keyspace_misses//indicates number of misses

Keyspace_hits//= number of Hits

Keyspace_hits_rate = keyspace_hits/(keyspace_hits + keyspace_misses)

Number of connected_clients//client connections

Blocked_clients//Client blocking number

Connected_slaves//From library number

INSTANTANEOUS_OPS_PER_SEC//Client executes command frequency per second

USED_MEMORY_RSS//The memory assigned to Redis by the operating system

Used_memory//redis Allocator Allocated memory

Mem_fragmentation_ratio//Memory fragmentation ratio in ideal cases,

The value of the Used_memory_rss should be only slightly higher than the used_memory. When RSS > used, and the values of the two differ significantly, there is a memory fragment (internal or external). When used > rss, some of the memory of Redis is swapped out to swap space by the operating system, in which case the operation can have a noticeable delay.
