Just modify the starting log format for viewing. Leave the zap log because most codes use zap function. After zerolog merged, we can replace zap with zerolog.

output in cmdline: stdout1

/var/log/s.log is json formatter: slog1

One note: "github.com/iotexproject/go-p2p" use zap.Logger now. If change to zerolog, this project should also change together. https://github.com/iotexproject/iotex-core/blob/c75411c117fb90cf4f7fb01b755c8f9b245ec7ac/p2p/agent.go#L195

Could this format of logs be indexed?

see comment in https://github.com/iotexproject/iotex-core/issues/3476, we need to achieve:

the output to log file is still same json format, for ELK log collection/analysis purpose
on top of that, if it's possible to make the output to commandline window better

replace with zerolog does not seem a good solution to achieve both

zap Encoder supportted customize log format，you can implement an encoder to replace default console encoder.

Because of ELK, the log file format can't change. I'll try to find the humanly-printed setting by zap console encoder.

add zap console encoder zap-console
