rrd2mysql gateway

Hi, I really need to get the rrd counters in a mysql database. I was able to hack hobbitd/do_rrd.c: on each update a perl script is executed with the parameters updparams[1], hostname, updparams[3] and updparams[4]. This is not working because for every update, the perl script is executed and this fills up the memory of my server. I also tried to replace the perl script with a shell script that puts all the data in a named pipe. But this blocks the hobbit rrd module. So, can anyone help with more C knowledge then I have? I was thinking about a non-blocking named pipe in hobbitd/do_rrd.c. Or maybe an extra communication channel like hobbit uses internal. The best solution would be adding mysql support to hobbit. but I also need to do some conversion of the data and I prefer to do this in perl. Thanx in advance, Stef

BBWin config file xml parsing API
by jon＠shadowsoft.com 24 Nov '08

24 Nov '08

Anybody have experience with writing extensions for BBWin? Specifically, I need to create three-tier configuration like: <extension> <foo param="param1"> <bar baz="baz1" /> <bar baz="baz2" /> <bar baz="baz3" /> </foo> <foo param="param2"> <bar baz="baz4" /> <bar baz="baz5" /> </foo> </extension> I can get to the foo's but not the bar's. It seems that GetConfigurationRange only seems to want to work one deep from the <extension> level... but there's a HIGH possibility that I'm doing something wrong. :-) Thanks, Jon

bbproxy over stunnel
by medavian＠gmail.com 24 Nov '08

24 Nov '08

Hello All, I have a problem getting stunnel and bbproxy to hobbitd to play nicely. I am not sure if this has been covered before, however I have found a few bits and peices of information about hobbit and stunnel, but nothing like what I have configured. Here is the idea.. client -> bbproxy -> stunnel -> stunnel ->hobbitd Client is a SQL server that can't see the world. bbproxy is running on a server behind a firewall that the SQL server can reach. bbproxy is configured to send data to 127.0.0.1:11984. stunnel is listening on 127.0.0.1:11984 this then forwards out through the firewall to another server running stunnel listening on 11984 this in turn dumps traffic on the remote server to port 1984 (hobbitd). This config works great, all my messages are encrypted and I am getting all the updates to hobbitd on the remote server no worries. Has been working like this for a few weeks now. The issue I have been trying to nut out is that the clients are not receiving any config in the other direction, particularly the log:/var/log/messages:10240 entries from client-local.cfg. If I remove the stunnel(s) and tell the bbproxy to connect to the hobbitd directly, the clients get the config data in the reverse direction and they in turn send back the log data they are supposed to. Has anyone been able to get this to work ? I suspect it may be my stunnel configs. they are below. Any help would be greatly appreciated.

Memory and CPU usage by a process
by vadud3＠gmail.com 21 Nov '08

21 Nov '08

Anyone worked on collecting data and generating rrd and graph for a particular process? I am trying to collect it for all the java processes on one system, which is easy for solaris, and then generate rrd and create graph. With little perl scripts, as provided in rrdtool website, I can generate the rrds as well using the data but how do I tell hobbit server to do the graph? I want to do it all in the server may be by modifying the `ps' script on the client to show the `RSS' column Thanks -- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu

Preparing a 4.2.1 release
by henrik＠hswn.dk 21 Nov '08

21 Nov '08

I'm preparing an official 4.2.1 release (should perhaps call it 4.2.2). This is for two reasons: 1) To put the all-in-one patch into an official release, which is apparently necessary. 2) To do a preliminary renaming from Hobbit to Xymon. 1) is obvious, and 2) is only for documentation and web- template changes. No new stuff. Except one new thing: The BBWin patch to allow the BBWin centralized config mode - I think this is important enough that it should go in now, since there are probably quite a few people who will want this in their setup. Anything else ? New feature stuff will not be accepted, this is purely a maintenance version until 4.3/5.0 arrives. Henrik

Extension of bbmrtg.pl: check on link down
by nelis＠nlr.nl 21 Nov '08

21 Nov '08

Hello, we are using MRTG to measure throughput connections between LAN equipment, and bbmrtg.pl to report the status to Hobbit / Xymon. bbmrtg.pl is extended to optionally check the status of a connection too, and report a 'red' status if the connection is down. We have found this a useful feature, as it detects link problems even in case redundancy in the network hides the problem. bbmrtg.pl is extended to take some special action if (A) variable bb*chklink is defined and (B) at the same time no input is received, thus 0 bytes per second, and almost no output is sent. There are two cases: if bb*chklink is negative, this condition is sufficient to set the status of the connection to 'red'. If bb*chklink is positive, it is assumed to be the ifIndex of the interface. Using SNMP, the current status of the interface is retrieved. If the status is "down", the connection status is set to 'red'. The small amount of output allowed takes care of some L2 protocols which are almost always active, such as STP or CDP. Note that this condition cannot be checked with the original version of bbmrtg.pl. That version cannot check for the condition that both input *and* output is (almost) zero. Attached is the list of modifications in bbmrtg.pl. Kind regards, Wim Nelis. ******************************************************************************************************* The NLR disclaimer (http://www.nlr.nl/emaildisclaimer) is valid for NLR e-mail messages. *******************************************************************************************************

os count
by michael.nemeth＠lmco.com 21 Nov '08

21 Nov '08

Did did a little perl program that does an os count produces count like hp-ux 3 linux 1 sunos 38. Run as a stand alone did not see the need to run out of hobbit. But Henrik wouldn't this be easy enough to add in to bbtest? Here it is: #!/usr/local/bin/perl eval 'exec /usr/local/bin/perl -S $0 ${1+"$@"}' if $running_under_some_shell; # this emulates #! processing on NIH machines. # (remove #! line above if indigestible) eval '$'.$1.'$2;' while $ARGV[0] =~ /^([A-Za-z_0-9]+=)(.*)/ && shift; # process any FOO=bar switches $[ = 1; # set array base to 1 $BBHOME="/home/mnemeth/sunhobbit/"; open (HOB, "$BBHOME/server/bin/bb 127.0.0.1 'hobbitdboard fields=BBH_OS test=info' |") ; while (<HOB>) { chomp; # strip record separator @Fld = split(' ', $_, -1); for ($i = 1; $i <= $#Fld; $i++) { $freq{$Fld[$i]}++; } } foreach $word (sort keys %freq) { printf "%s\t%d\n", $word, $freq{$word}; }

New section for solaris

Hi Henrik, If it is not too late I like to request a [prtdiag] section for solaris and a prtdiag column. The prtdiag report is very useful for solaris systems Thanks -- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu
