Building KV Pairs

Hi folks,

I am trying to build KV pairs from some UNIX command output. The log entries look like the output below. In this case I would like to build keys from the headers (%usr, %sys, %wio, %idel) and values for each from the values shown (2, 5, 0, 93). I will then graph multiple entries over time. While the preview here shows this all in a line, the log is a preformatted table.

HP-UX van-sama B.11.31 U ia64 08/21/12
12:49:47 %usr %sys %wio %idle
12:49:48 2 5 0 93

The likely search function seems to be "extract(kv)" but I am unclear on how to go about this and the examples in the docs seem weak.

Can anyone put me on the right track?

Thanks 🙂

Good idea but it still failes. Thanks for the help. Multikv seems the answer but doesn't do what we expect it too. Not sure why! Thanks again for the ideas 🙂

Multikv will replace non alphanumeric chars with underscore.
See if this does the trick:

... | multikv fields _usr _sys _wio _idle

Thanks for your responce but this doesn't seem to work. No change in the results I get at all. I wonder if it could be the % characters. It certainly doesn't build KV pairs as I would expect it to.

Any other thoughts anyone?

Multikv seems more appropriate than extract in your case:

... | multikv fields %usr %sys %wio %idle
