Zabbix Automatic Discovery Monitoring Redis

1: Write the automatic discovery script on the Zabbix_agentd side, mainly to automatically discover the monitoring port of Redis, 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 have not find"

Exit 2

Fi

Count= ' echo ' $res ' |wc-l '

If [$count-eq 0];then

echo "Redis have 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\t\t{\" {#REDISPORT}\ ": \" $line \ "}\n"

Else

printf "\t\t\t{\" {#REDISPORT}\ ": \" $line \ "},\n"

Let "mycount++"

Fi

Done

printf ' \t]\n '

printf '}\n '

Exit 0

The automatic discovery script needs to be noted:

1:visudo Zabbix user needs the operation of the SS, configured as follows, Visudo:

Zabbix all= nopasswd:/usr/sbin/ss

Defaults:zabbix!requiretty

2: Configure the following on the Zabbix_agentd side:

userparameter=zabbix.discovery.redis,/usr/local/zabbix/zabbix_discover_redis.sh

Userparameter=redis.status[*],redis-cli-p $ info|grep "$:" |cut-d:-f2

Where to look for configuration:

1:zabbix_discover_redis.sh Zabbix need to have execute permission

2:redis server does not set the password situation, otherwise it will generally have to add a verification.

3: Restart ZABBIX_AGENTD after configuration

3: Create a template in the Zabbix server's Web page configuration, name such as: template Redis Discovery Service

4: Create a Discovery rule: The name is: Redis Discovery, key value configuration: Zabbix.discovery.redis.

5: Create the project prototype, the name and the corresponding key values 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]

Monitor the number of client connections, memory fragmentation, and Redis port survivability detection for Redis, respectively.

6: Create a trigger:

1: For Port checking

2: Depends on port check for the number of connected clients

3: Depends on port check for fragmentation

7: Create a graphical prototype:

1: Number of client connections

2:redis uses memory and actually practical memory.
