Does it support Azure Cache for Redis?

@mehmetcakmaz Please let me know if you were able to connect to Azure Cache.

@mikhailredis You're right, that setting did it, hooray 👍

Now I've got a redis datasource up and running!

Thank you very much again for your help!

@mehmetcakmaz Thank you for your interest in the plugin. You should be able to connect to any Redis instance. TLS connection is supported as well.

Please let me know if you have any troubles connecting to Azure Cache.

Thank you for information @mikhailredis
I will try and notify you within 1 week

Hi @mikhailredis,

currently, I'm trying the same and had no success so far. I'd like to connect to an instance of "redis cache for grafana". However, I have not been able to find a way of enabling SSL in the grafana plugin for redis.

The "Connection string" shown by Azure is:
"[instance-name].redis.cache.windows.net:6380,password=[base64 encoded password],ssl=True,abortConnect=False"

I've copied the base64 encoded password into the "password" field in the redis plugin and tried the following URLs with no success:

• [instance-name].redis.cache.windows.net:6380
• redis://[instance-name].redis.cache.windows.net:6380?ssl=true
• redis://[instance-name].redis.cache.windows.net:6380/?ssl=true

In all cases, the error message was getInstance error: read tcp [IP]:58070->[IP]:6380: read: connection reset by peer after a timeout of 15-20 seconds.

I'd be happy to try out other URLs if you've got any ideas.

Thanks in advance, Tobias

@tbraun-hk You don't need to use SSL in the URL, as it's enabled by default as I understand.
Did you provide an SSL authority certificate or enabled Skip to verify?

Meanwhile, I will try to connect to Azure and get back to you shortly.

@mikhailredis thank you very much for the quick reply! Here's a screenshot of my attempt of configuring the plugin, I hope, this is useful to you?

However, I just realized that I'm not able to access the same redis instance using redis-cli. So it's most probably not an error in your plugin but rather an issue in my setup. I'll keep investigating and send an update once I got redis-cli up and running.

According to Azure documentation, TLS/SSL is not supported by redis-cli: https://docs.microsoft.com/de-de/azure/azure-cache-for-redis/cache-how-to-redis-cli-tool

[tbraun-hk]

OK, here's a success message: After enabling unencrypted access to redis, the plugin is working flawlessly!

Still, it would be great to be able to use TLS encryption. Maybe there's a way?
I really appreciate the time and effort you're making in providing and supporting this plugin, @mehmetcakmaz. Thank you very much!

@tbraun-hk Please try to switch "TLS Client Authentication" to enable and provide Authority certificate or enable 'Skip Verify'. Don't need to provide client certificate or key if you don't use them.

@tbraun-hk You are very welcome! Let me know if you need anything else.
