wulflogger (current: v0.2.0, 6/20/04) is a derived cousin of
wulfstat that monitors very similar statistics but just writes them out
to stdout in an easily parsed, timestamped format. The output can then
be redirected into a file or piped into perl or other scripting
languages for further processing and display in fancier media, e.g. a
graph, report, or web page. It uses the same format as the wulfhosts
file(s) of wulfstat and requires xmlsysd to be
installed on the monitored nodes or LAN workstations.
wulflogger seems to be working well enough at this point to consider
it to be production software -- I'm working hard to keep it up to date
and reasonably well debugged. It is being used in the associated wulfweb project that should be in this
If you need any particular output from wulflogger let me know.
Eventually I'll probably come up with an output format descriptor that
can be read in as input so you can roll your own format and get
precisely what you want, but we're not there yet.
SPECIAL NOTE: As of v0.2.0, wulflogger requires unsigned long
long ints to handle 2.6 kernel fields, which in turn requires a compiler
that supports strtoull() correctly. gcc does, but only with the
-std=c99 flag, so wulflogger (and libwulf) now build with this flag set.
This may impact buildability on older systems. Please report problems
to the list or to rgb.
