Zabbix automatically detects and monitors redis

Zabbix automatically detects and monitors redis

1: Write an automatic detection script on zabbix_agentd, mainly to automatically discover the redis monitoring port. The script is as follows:

Vim/usr/local/zabbix/zabbix_discover_redis.sh
#! /Bin/sh
# Zhuangweihong 20160419 zabbix discover redis

Res = 'sudo ss-tulnp | grep redis | awk' {print $ (NF-2)} '| awk-F': ''{print $ (NF )} '| sort-U'
If [[-z "$ res"]; then
Echo "redis has not find"
Exit 2
Fi
Count = 'echo "$ res" | wc-l'
If [$ count-eq 0]; then
Echo "redis has not find"
Exit 2
Fi
Printf' {\ N'
Printf' \ t "data": [\ N'
Mycount = 1
Echo "$ res" | while read line; do
If [$ count-eq $ mycount]; then
Printf "\ t {\" {# REDISPORT} \ ": \" $ line \ "} \ n"
Else
Printf "\ t {\" {# REDISPORT} \ ": \" $ line \ "}, \ n"
Let "mycount ++"
Fi
Done

Printf' \ t] \ N'
Printf'} \ N'
Exit 0

Notes for automatically discovering scripts:
1: The zoodo zabbix user needs the ss running permission. The configuration is as follows:

Zabbix ALL = NOPASSWD:/usr/sbin/ss
Ults: zabbix! Requiretty

2: Configure zabbix_agentd as follows:
UserParameter = zabbix. discovery. redis,/usr/local/zabbix/zabbix_discover_redis.sh
UserParameter = redis. status [*], redis-cli-p $1 info | grep "$2:" | cut-d:-f2

Notes for Configuration:
1: zabbix_discover_redis.sh zabbix requires the execution permission
2: The redis server does not have a password. otherwise, an additional verification is required.

3: restart zabbix_agentd after configuration.

3: configure a Template on the zabbix server webpage, for example, Template Redis Discovery Service

4: Create a Discovery rule named Redis discovery, key value configuration: zabbix. Discovery. redis.

5. Create a project prototype. The name and corresponding key value are as follows:
{# REDISPORT}: Redis Connected Clients redis. status [{# REDISPORT}, connected_clients]
{# REDISPORT}: Redis mem_fragmentation_ratio redis. status [{# REDISPORT}, mem_fragmentation_ratio]
{# REDISPORT}: Redis Port Check net. tcp. service [tcp, {# REDISPORT}]
{# REDISPORT}: Redis used_memory. redis. status [{# REDISPORT}, used_memory]
{# REDISPORT}: Redis used_memory_rss. redis. status [{# REDISPORT}, used_memory_rss]
Monitoring redis client connections, memory fragments, and redis port survival detection respectively.

6. Create a trigger:
1: Port Check

2: The number of connected clients depends on port check.
3: for fragmentation, it depends on Port Check

7. Create a graphic prototype:
1: Number of connected clients

2: memory used by redis and actually useful memory.
