I've written my --extra-script (based on the sample in the hobbitd_larrd man page) and added this as well my columns for the --extra-tests in hobbitlaunch.cfg under the larrdstatus command.

Brave man - you're the first to try out this mechanism for real:-)

Wheeeeeeeee! Bring on the pain! ;-)

...

My script is getting executed OK. I've added some debug messages which get appended to a log file and most things are running as expected. However, I'm getting no actual data, no rrd files and no graphs :-(

It seems the the $FNAME parameter is not giving me what it shoud, and this is causing my tests to echo the DS line, the rrd file name, but an empty data string.

Quite the opposite it turns out. I added some extra debug lines to cat $3

• lo and behold, there was my expected output in all its glory. My bad.

Once I *fixed my grep* I started getting data and rrd files ( I was grepping for text at the start of the line, but the report included a leading space).

Of course, my original "cp $FNAME /tmp/$FNAME.$TESTNAME.$$" in debug wasn't working because I didn't basename $FNAME first. Duh.

My remaining problem is that after colecting a few data points, I still have no graphs on the test pages or the trends page. I'm off to bed now and will re-check tomorrow morning. But if you know of anything else I may have missed please let me know! Should bb-hostsvc.sh pick it up automagically?

Some shell's do have slightly different syntax than what the example script in the man-page shows. You could try just echo'ing the input parameters to some file and see what they are. Like

echo "Input 1: $1" > /tmp/params.txt echo "Input 2: $2" >>/tmp/params.txt echo "Input 3: $3" >>/tmp/params.txt

at the top of your script (before they get put into the $FNAME etc).

...

I'm running 4.0-RC2 on Solaris 9 x86.

Something in the back of my head says: Could you try putting the input params inside curly brackets ? Instead of

HOSTNAME="$1" TESTNAME="$2" FNAME="$3"

try HOSTNAME="${1}" TESTNAME="${2}" FNAME="${3}"

Henrik

This wasn't an issue of course - plain old $1, $2 and $3 are fine.

Thanks for the help (and of course the awesome tool).

On to Oracle data... and maybe some c modules to replace my script.

Cheers, Andy.

[success story]

Congrats - it's nice to know this mechanism works. Doing it in my "lab setup" is often very different than what goes on in real life.

No, there are a couple of tweaks you must do for that to happen.

The LARRDS and GRAPHS settings in etc/hobbitserver.cfg must be told about this new graph.

If the column-name for your custom test is "xyz", then you just add "xyz" to the LARRDS setting - when bb-hostsvc.cgi then builds the status display, it will know to include the graph on the webpage.

If you want the graph also to appear on the "trends" page with all the other graphs, you must also add it to the GRAPHS setting.

In either case, you of course have to setup hobbitgraph.cfg with the RRDtool definitions for this new graph, so it knows how to generate the graph from your data.

Awesome!

I've updated etc/hobbitserver.cfg for my new columns, tweaked my entries in etc/hobbitgraph.cfg, and now have a funky graph that shows a 10 volt variance on my UPS input over the last 10 hours!

Thanks again, Andy.

Currently I am forwarding (via BBRELAY option) all of my BB status messages to my test Hobbit server. This allows me to fully test hobbit, configure alerts etc, without disrupting my "production" bb server.

Once I make the full switch to hobbit, what is the best way to move as much of the historacle information as possible over to hobbit? I assume I could copy the rrd files over? What about the history logs? I mainly don't want to lose my year of rrd info.

From BB's bbvar/ directory, move the "hist" and "histlogs" directories directly to Hobbit's data/ directory. That way you'll keep all of the historical status logs.

For the RRD files, they must be moved and renamed. There's a "moverrd.sh" script in the "hobbit-4.0*/hobbitd/" directory, which will help you with moving or copying the RRD files from BB to Hobbit. Note that this script requires that your Hobbit bb-hosts file has all of the hosts listed.

You cannot move the netstat RRD files over, since the data layout is different. That goes for the vmstat RRD files from Linux hosts as well. The rest of the RRD files are compatible between BB/LARRD and Hobbit.

I have tried to change the default port number, changing the BBPORT in hobbitserver.cfg, but the daemon always started on port 1984. So i have added, in hobbitlaunch.cfg, the hobbitd option --listen, and the daemon start on another port.

One question If i use the general option, BBDISPLAYS, in hobbitserver.cfg, i can have more bbdisplay?

OK, fixed in hobbitd so it looks up the BBPORT setting instead of defaulting to 1984.

After i change the port, no more status client arrived to hobbit server.

If you set BBDISPLAYS, then the tools that generate status-messages - i.e. bbtest-net, bbcombotest, bb-infocolumn, bb-larrdcolumn - will send those messages to all of the BB- or Hobbit-servers running on those adresses you put in BBDISPLAYS.

If you do use it, then you must also set BBDISP to "0.0.0.0"

That is the way BB behaves, and Hobbit follows that.

It's possible to also specify the port of the other servers?

thank for helps

congratulations for your work!!!

Yes, I think that's the easiest way to setup those environment variables (BBWEB) that must be changed for each pageset.

You can check the content-type header with the "type" check, see the bb-hosts man-page. But there's not a general mechanism to look at any random header-value.

It's possible also to add others http code status ?

No.

there is the way to add an option, to not show the url and the output of the cont test ( i use it to check intranet applications, or admin test applications)

No. My best advice is to put them on a separate page in BB and control access to that page via .htaccess files or such.

In my bb installation i have renamed the conn test as 'link'.

I would like to change it also in my hobbit installation [snip changes] Now the column link is generated but no larrd graph.

The "conn" columnname really wasn't configurable - hobbitd_larrd would always assume it was either "conn", "fping" or "ping".

So I took this as an opportunity to clean it up a bit. The ping column name is now defined solely via a PINGCOLUMN environment variable.

Also, I decided that having to mess with the LARRDS setting just for network tests was silly. So instead, all of the RRD- and graph-code will automatically pick up simple network tests from the bb-services file.

where i could set this variable? is not more used the bb-net option --ping=conn-name

In hobbitserver.cfg, but it will not work with the software you have. You'll need 4.0-RC3 which I haven't released yet.

how to add a custom larrd graphs?

See the man-pages for hobbitgraph.cgi and hobbitgraph.cfg

Two things:

1. You must use the "--hobbitd" option when running bbgen on top of Hobbit. if you don't it will try to read the BB status logfiles instead of the Hobbit network status.

2. The "--larrdgraphs=*" option probably needs to be in quotes.

Nothing yet are created in the directory www/nal

My hobbitlaunch.cfg: CMD bbgen --hobbitd --recentgifs --subpagecolumns=2 --larrd043 --report

I would like to have two hobbit server on the same machine, running on different ports. One of these must send to the other (port 1984) the test results. I try to use the BBDISPLAY option but nothing is arrived on the other server. Seems that the sender server post the status message not to the default port. Any ideas? On the reicer server i must enable status channel?

hobbitd was never designed to do this. It receives messages, it doesn't send them.

If you want to forward incoming messages to one or more hobbit servers, use the bbproxy (also part of the Hobbit package).

I try to use bbproxy, but it send only the message status coming from the client

...

I try to use the BBDISPLAY option

which is 100% ignored by hobbit. BBDISPLAY, BBPAGER, BBNET and BBRELAY are for BB - hobbit ignores them.

I think BBRELAY may be important, specially when you are migrating to a new server.

sorry, i use BBDISPLAYS in the hobbitserver.cfg, but the problem is that is not possible to specify the port, seems that it use the same port number.

So you think is possible to make a configuration, using only one hobbit server, to have two http servers (private and pubblic)? I try to use alternate pageset to make this, but i have two problems:

1. in hobbit seems not support more the nodisp option in bb-hosts as bbgen
2. the bb2 page, report and others cgi, show all the entries of my bb-hosts. You think it's possible to make a custom header, where the cgi read a specific bb-hosts file ?

thanks for your help and your work

You cannot run to hobbit servers off the same data directory. There is no file locking in hobbit, so you would easily end up with garbage files.

Do you think it's possible to force the restore status, for one server, every xx seconds from the file hobbitd.chk?

Sorry Marco, but I simply cannot figure out what it is you are trying to accomplish with this setup. I have a strong feeling that you are doing something very simple in an extremely complicated way.

I *think* you want to setup a server with two sets of hosts - one set is for use by one group, and another set is used by a different group.

If you want these two completely separate, setup two full Hobbit installations - two userid's, two server-directories, two data-directories, everything completely separate. When you build the two installations, build them with different BBPORT settings so you can have both hobbitd's running at the same time - or better: If you have extra IP addresses available, let each of them have their own IP address so you don't need to worry about changing port numbers. If everything runs on the same server, you can use 127.0.0.1 and 127.0.0.2 !

Each installation runs his own network tests, so they will also be separate.

The only problem I see is if you want data from client installations. That's where you use bbproxy. Set it up to receive client messages, and forward them to both of the two hobbit daemons.
