Step 1: write the port discovery script redis_port.py for redis python

#! / usr/bin/env python

Import os

Import json

T=os.popen ("" ps aux | grep-v grep | grep redis-server | awk-F'*:'{print $2}'| awk'{print $1}'")

Ports = []

For port in t.readlines ():

R = os.path.basename (port.strip ())

Ports + = [{'{# REDIS_PORT}': r}]

Print json.dumps ({'data':ports}, sort_keys=True,indent=4,separators= (',',':))

Write a port discovery script check_redis_port.sh for redis shell

Zabbix template configuration

Automatic discovery

Trigger

{HOST.NAME}: {# REDIS_PORT} redis ping exception, please check

{Template for redis:redis.liveness [{# REDIS_PORT}] .str (PONG)} = 0

{HOST.NAME}: {# REDIS_PORT} redis memory utilization > 80%, reaching {ITEM.LASTVALUE1}%

{Template for redis:redis_used_memory_per [{# REDIS_PORT}] .last ()} > 80

Restart after zabbix configuration file is added

UserParameter=redis_port.discovery,/app/sinova/zabbix/scripts/check_redis_port.sh

UserParameter=redis_used_memory_per [*], / app/sinova/zabbix/scripts/redis_used_memory.sh $1
