Fix exeption.log file path

[sauliusgrigaitis]

@sntntn exception.log file by default must be written to <data-dir>\<network>\exception.log

[sauliusgrigaitis]

Also, now seems that Grandine just exits silently if it can't write that exception.log file. It needs to fail with error message and stop the client if this exception.log file is mandatory or alternatively just a warning and proceed with execution.

Makes sense. I'll do it today!

@povi is already working on it.

I suggest to explore the metrics as we talked before.

excellent, then I'll move on metrics research :D
I suppose @povi would also rotate the exception.log file after exceeding memory limit then
