RE: {bb} Disk and LARRD

["Wu, Hai" <hxwu@tribune.com>]

Hi Phil,

The following are the output from the server, I can see the graph for them in "trends", but not in "disk".
If it's due to "-P" flag, how to fix it?

Thanks,
Hai

I sense a theme developing here :)

Because of the way that Larrd organises it's data, "/boot" will often
be the first partition that it attempts to graph. That suggests that
something in the format of the "df" output (as used by BB) is causing
confusion for Larrd. If you take a look in the directory where the
database files are stored (usually $BBVAR/rrd), you should be able
to identify whether Larrd is successfully storing the data for the
other partitions or not.

The thing which has caused similar problems in the past is the
format of the data that BB is collecting. If you compare it with
other hosts which are working well (or post the output here), it
may be possible to identify what is causing a problem for Larrd.
On some versions of Red Hat it may be necessary to use the "-P"
flag to the "df" command (on the client) in order to get POSIX
style output format.

Cheers, Phil.
