What's the meaning of these log entries?

[warg]

Hello,

I see entries like these in the log of my Nextcloud app:

[...]
May 20 20:49:22 11:M 20 May 2023 18:49:22.055 * 10 changes in 300 seconds. Saving...
May 20 20:49:22 11:M 20 May 2023 18:49:22.056 * Background saving started by pid 645
May 20 20:49:22 645:C 20 May 2023 18:49:22.066 * DB saved on disk
May 20 20:49:22 645:C 20 May 2023 18:49:22.067 * RDB: 0 MB of memory used by copy-on-write
May 20 20:49:22 11:M 20 May 2023 18:49:22.156 * Background saving terminated with success
[...]

What's the meaning of entries like "11:M" and "645:C"?

Best Regards,

redis logs are of the format pid:role timestamp loglevel message . pid is container local.

Role is:

• X sentinel
• C RDB/AOF writing child
• S slave
• M master

Unfortunately, there is no way to change the log format in redis (afaik). We just need the message really (others are not useful on Cloudron). See also https://github.com/redis/redis/issues/2545
