This is just a simple CLI tool for filtering JSON logs that has a syntax similar to Loki.
$ toki [logfile]
[col1,col2,col3] -> { key: "value" } |= "search query" ~last5m
^ the list of ^ search by ^ raw search ^ time interval
columns to JSON values query
show in log
Example (filter nest.js error logs related to the database in the last 5 minutes):
[level,time,msg] -> { level: "error" } |= "database" ~last5m
