Explore feasibility of open-source log collection tools

## References

- https://github.com/lablup/backend.ai/issues/3007
## Motivation

I would like to determine which open-source tool is most suitable for setting up a log collection system in backend.ai.

## Main Tasks

The following considerations should be taken into account:

- Aim to avoid creating **too much complexity** during the installation process.
- The log collection system should not be overly heavy.
- The log collection system must operate reliably even if the volume of logs increases significantly.
- There should be smooth integration with a server that performs log filtering and visualization after log collection.
## Expected Results

- I hope to document and discuss how to apply each open-source tool and identify which one is the most suitable.
