Custom filename creation for all sinks

[ldionne]

Currently, I think only the daily logger allows customizing the filename format. I'm trying to replace our internal logging framework by Spdlog, and I need to encode the date in the filename (but without using a daily logger, which is too coarse grained). Instead, I want to generate a new filename every time a size-based sink "rotates". I might be able to provide a PR if there's interest for solving this issue.

Thanks. That would be useful.

Do we have an example of how to achieve this?

The daily sink already has such possibility

How is the progress on this issue?

I need this feature as well - specifically using "datetime" instead of "index" suffix for rotated files - similar to that provided by logrotate dateformat with second resolution.

Is there any progress on this issue or a suggested workaround to achieve this?

Does this PR solve this problem?

[alokpr]

IIUC daily sink only rotates daily. I need file size based rotation.

[KonradJPE]

I also need this feature. Is there any general schedule regarding this topic?

I would need this feature as well for size based rotation

Any updates to the issues?:

1. allow file syncs to customize file names (e.g. add process name, add timestamp, etc.) - although it was stated that the daily file sink can do this I see no example of this via config file. the daily file sink appends the year/month/day to the file name automatically ... it is not customizable from a config file from what we can tell?! what are we missing? how is this done through config file?
2. rotate file based on filesize - is this working? how is this done through config file?
3. create new log on process crash - how is this done through config file?
   Thanks!
