Hello, Pavel
I have problem with this steps:

Installation (OPTIONAL)

• Replace following line your.first.redis.host.local under zbx_screens/zbx_export_screens.xml with your first redis host
  (replace 'your.first.redis.host.local' to 'redis01.intra' (this is my local IP for redis server)
• Import saved file zbx_export_screens.xml via Zabbix -> Monitoring -> Screens
  When i importing.... zabbix web throw me this message "Cannot find graph "Redis: "{#INSTANCE}" - {#COMMAND} Calls Overview" used in screen "Redis Monitoring: Redis Command Overview".

Other steps complited successfuly.
Please, help to resolve this issue.... thanks

Cannot find graph "Redis: "{#INSTANCE}" - {#COMMAND} Calls Overview" used in screen "Redis Monitoring: Redis Command Overview".

Hello,

I have installed your template, and I don't understand why it's not working. Discover Redis Commands and Discover Redis Slaves are working correctly, but Discover Redis Instances shows as Not supported in Zabbix. The error message is Value should be a JSON object., but the output looks like a valid JSON.

{"data":[{"{#HOST}":"127.0.0.1","{#PORT}":"6379","{#INSTANCE}":"REDIS","{#RDB_PATH}":"/var/lib/redis/dump.rdb"}]}

Here is my debug

I don't know if it's related, but I see REDIS_MAX_CLIENTS is blank in output message. If I execute the command I see there in the command line, it works

$ stdbuf -oL /usr/bin/redis-cli -h 127.0.0.1 -p 6379 -a debug config get '*maxclients*' | sed -n 2p

What can be wrong in my setup?

Thanks

$ locate redis-cli

Using locate redis-cli seems iffy. In this case, the real binary is the very last item, but the script uses the first item, which is a bash completion script. If redis-cli is on PATH, which redis-cli seems better

Hi,

I am trying to use this template with zabbix 5.0.10 however I fail to upload the template file through zabbix frontend. I assume this is because zabbix 5.0 requires different syntax than zabbix 3.4.

Do you have the template file for zabbix 5.0?

Here is the error I get during the upload.

Invalid tag "/zabbix_export/templates/template(1)/discovery_rules/discovery_rule(1)/graph_prototypes/graph_prototype(1)/graph_items/graph_item(1)/type": a character string is expected.

thanks in advance

Leave it empty will cause error.

Hello!
I can change {$REDIS_PASSWORDS} for all templates, but how i can specific setup different password for others several servers ?
And if password is not correct for new server, discover app redis will not be created

Problem with importing template.
Cannot read XML: (41) Specification mandate value for attribute data-pjax-transient [Line: 43 | Column: 89].

Hello, Pavel!

If it's possible, please help!
Seems like i did something wrong, or didn't understand something.

I set all userparametrs directly in /opt/zabbix/etc/zabbix_agentd.conf. Path to script is set here
UserParameter=redis.discovery[*], /opt/zabbix/etc/scripts/zbx_redis_discovery.sh $1 $2

I edited /opt/zabbix/etc/scripts/zbx_redis_discovery.sh to specify redis location:
REDIS_CLI_DEFAULT_PATH="/opt/redis/bin/redis-cli"

When i run zbx_redis_discovery.sh general debug, few files redis-127.0.0.1-6379* in /tmp are created with root privileges.
After this i can request some information with
./opt/zabbix/sbin/zabbix_agentd -t redis.stat.get[expired_keys,127.0.0.1,6379]
redis.stat.get[expired_keys,127.0.0.1,6379] [t|29562818]
And remotely the same.

But i get, only what is in redis-127.0.0.1-6379 file (so it's not in realtime)

chown zabbix.zabbix redis-127.0.0.1* didn't help.

I imported template in gui, but it show Timeout while executing a shell script.

Here's resutl of zbx_redis_discovery.sh general debug
