As mentioned in a sibling comment, https://goaccess.io is probably best for simple analytics on log files. If you want to write more complicated queries, lnav exposes log data through SQLite vtables[1]. So, you can do a SQL que

I'm the author of lnav and had never heard of logviewplus before, thanks for mentioning it. It looks like we've independently arrived at a very similar feature set, that's pretty neat. I will now shamelessly steal some of y

lnav does support JSON-lines and logfmt logs. For JSON-lines, it will pretty-print the log messages to make them human readable. For logfmt, I seem to remember the spec not being very clear on quoting semantics (maybe I'm wrong). Any

lnav has some support for tailing files on remote hosts -- https://lnav.org/2021/05/03/tailing-remote-files.html It works by uploading a stub that is an "actually portable executable" to the remote

I don't think multitail really understands logs like lnav does, it's just following the last lines in the file. For example, if you try to follow multiple files in multitail like so: $ multitail /var/log/inst

Oh, okay... https://lnav.org is a log file viewer for the terminal that integrates with SQLite so you can use SQL to query your log files. No benchmarks, though.

I used to use jasmin to generate invalid code to test an old JVM. I assume this has the same relaxed attitude that will let you generate invalid code?

Can you elaborate on why you don't think it's a tailing tool? lnav monitors the files it was pointed at and will load new data as it is appended or reload the file if it has been overwritten. Also, if you are scrolled all the wa

Yes, one of the advantage of language support is that "sOpen" will be consumed by the "close()" call and can't be reused. I don't think that's really possible in Java without an extra checker. But, it&#x
