graph problems 🔗 link

Hello,
I have just copied my old big brother data files (history and rrd) to a new hobbit 4.0.4 installation, it seems to work well except some problems with rrd file:


- on all linux client the vmstat graph was empty, and the error message
was:
/dati/hobbit/data/rrd/blu/vmstat.rrd from 127.0.0.1: unknown DS name 'cpu_w'
i have deleted the bigbrother vmstat.rrd, and the new one is correct.


- on all AIX, linux and solaris client the netstat is empty. if i delete the rrd file, it is recreated on aix and linux (still empty however), but not for solaris.

the log for linux machine:
larrd-status.log:2005-07-06 14:39:34 RRD error updating /dati/hobbit/data/rrd/blu/netstat.rrd from 127.0.0.1: expected 13 data source readings (got 16) from 1120653574:102891:105479:0:17502925:398003:0:18201:0:U:U:U:U:40401904:26965995:U:453087:...

for solaris machine:

- on all windows client, the "memory" graph is always zero (not empty).

how can i debug this situation?

thanx

OK, i have seen that this is documented .. sorry

It seems that i have found something wrong in larrd/do_la.c : the first error seems a typo, that zeoes the data collected.
the second is that the function atol return a signed long integer, and cannot report memory sizes > 2Gb.

I have written a small patch, using a specific gcc extension: the function atoll and the long long integer (64 bit).

I am the only one having trouble with memory graph on windows machines???

OK, that one looks like a genuine bug. Thanks for the fix.

Yes, that is a problem - but I'm not sure it really has any importance
here. The do_la.c code only handles memory statistics *if there is no
bb_memory* extension active on this host. So it only receives the memory reports that the BBNT client embeds in the cpu report - and as
far as I know the BBNT client uses an old Win32 API that cannot handle more than 2 GB of memory.

I think most people are using the bb_memory extension script.

Unfortunately this will cause problems for those who do not use gcc to compile Hobbit. I'll see if I can find a more portable solution.

BBNT correcty report memory up to 4Gb.
I have also a machine with 8Gb (win32 + PAE ..) and BBNT reports olny 4Gb, i have tried bb-memory with the same result.

Just to return on my original post, with bb-memory extension i see the "netstat" reports from windows, but i still can't view the graph, the error is

the file netstat.rrd is created, but "rrdtool dump netstat.rrd" show only NaN :(
i attach the message as i see it in the hobbit web page, i see nothing stange there ..
thank

Somehow you're getting a "netstat.rrd" file created that is in the wrong
format. Hobbit always generates netstat.rrd files with 16 datasets,
never 13. Could you try running this:

rrdtool dump /dati/hobbit/data/rrd/ctxdc1/netstat.rrd |grep "<name>"

This will show the datasets defined in this RRD file. I suspect that it
has been generate by the old netstat-larrd.pl script from LARRD.

                 <name> tcpRetransPackets </name>

I am sure that this file was generated by hobbit, because i never had a netstat graph for windows machines.

thanx for your help
