Azure Redis Cache update logs

Hi Azure Cache for Redis team,

We have been experiencing service outages in one of our App Services when instances permanently lose their connection to the Azuire Cache for Redis.

Every time these outages occur we see also see a Redis Cache error with ErrorType=Failover at the same timestamp.

We would like to determine if these outages we experience are due to Redis Cache updates as mentioned on the Azure Cache for Redis - Cache Failover page - https://learn.microsoft.com/en-us/azure/azure-cache-for-redis/cache-failover or if they are something else.

Where can we find the log of Redis Cache updates and also, aside from scheduling when updates can occur, can we learn before hand when an update will be applied?

    Hi @J Fowler

    Here are few documents that give the complete Troubleshooting guide for Azure Redis Cache

    1. Server Side
    2. Client Side
    3. TimeOuts
    4. DataLoss

    Server side patching definitely has a effect as explained in one of the document above.

    Please go through these and check if these help and the application should be prepared for patching outages and the document explains the same. If that is not possible, the right way forward is to contact support and work with them regarding the Failover error type.

    Hope this helps.

    Thanks
