Mixing json with non-json logs

[Tony Lam]

Hi,

Also, does lnav support reading logs with both json and non-json logs?

If yes, any example that I can take a look?

Thanks

Do you mean in a single file there are JSON-lines with non-JSON content?

Yes, the same file has JSON-lines and non JSON-lines.

A mix of JSON-lines and non-JSON-lines is not really supported.  I made a

change for v0.11.1 that will cause the lines to be shown without a noisy

parser error.  However, the lines are not parsed in any meaningful way.  I

would suggest writing the different types of data to separate files.  lnav

can load them both and will interleave the messages by time when

displaying them.

Got it.

Separately, does lnav support multiple non-JSON formats in the same file?

Thanks

[lnav support]

A log file is associated with a single format.  A format can have

multiple regexes for matching lines, though.  That is mostly

useful for cases like the message formats changing between

versions of an application or an application outputting slightly

different messages.
