Turns out the installation on my system was from the OS/X DVD which included that. Something I had installed put a different 'head' on my system, so I found the original and restored in. Hobbit is up and running! I read (or so I thought), there was a GUI configuration interface? I thought I read there was one built in? Thanks again for everyones help.

Differences between bb and hobbit -
by joe＠tmsusa.com 06 Nov '07

06 Nov '07

Hello list, I've gotten a pair of hobbit servers set up, one in each data center, in a specific lan. I'm noticing that, due to the many transient network glitches in wan connectivity, that the hobbit history shows a lot of red/green/red/green. This appears to be different behavior from bb, which gives us some knobs to turn, mitigating the effects of the transient glitches and preventing the alternating red/green connectivity status. (We've got people watching bbdisplay pages, who panic when they see red.) If a bb-net test fails, bb waits "n" seconds and tries again, and if it still fails, it waits "m" seconds and tries a third time, and if that fails as well, the connectivity goes red. The delays between try 1 and try 2, and the delay between try 2 and try 3, are configurable in bb, but I don't see any such option in hobbit, nor is it obvious whether there is more than 1 attempt made to perform a network test. Can anyone confirm or deny that this is the case, and if not, point me to the correct configuration option? Thanks & Regards, Joe

Extend Hobbit server from external Company sites
by johan.boye＠latecoere.fr 06 Nov '07

06 Nov '07

Hello, I'm running a Hobbit server on a place A. There, it monitors a couple of servers, databases, filers... I would like to run another Hobbit server on a place B to monitor machines on the B place. Is there a way to give feedback to the A-Hobbit server if there are red errors on the B-Hobbit server ? Thanks, Johan "Les informations contenues dans ce message electronique peuvent etre de nature confidentielles et soumises a une obligation de secret.

[hobbit] Creating a fake, or combination, client
by Martin.Ward＠colt.net 06 Nov '07

Thanks Gary, I think the thing I am missing in your example (and in general to be honest) is: What is the link between fake-host in the bb-hosts file and [custom-postfix] in the hobbitgraph.cfg file? |\/|artin -----Original Message----- From: Gary Baluha [mailto:gumby3203 at gmail.com] Sent: 06 November 2007 15:34 To: hobbit at hswn.dk Subject: Re: [hobbit] Creating a fake, or combination, client On 11/6/07, Ward, Martin <Martin.Ward at colt.net> wrote: Hi all, I am a newbie to Hobbit and have inherited a working system. I have a good idea of how it all hangs together but now I want to produce certain graphs and cannot figure out how. I have a cluster of mail servers that run Postfix; each of these clients is monitored within Hobbit. In the Trends link for each client I have graphs showing the various mail queues (incoming, deferred etc) and this data is stored in RRD files on the Hobbit server. Is there a way within Hobbit of creating a false or meta- client that can have a graph with data from all of these RRD files? Particularly I would like a graph that has all the incoming mail queue sizes on it with one line per server. I already have this information in lots of different RRD files but would like to have them all in one graph. I can create a graph outside of Hobbit to do this, but within the monitoring system it restricts the RRD files it will display data from to those in the data directory of the selected client (in the Trends link). Hmm. You could probably create a host and set up a noconn test to some random IP like 10.0.0.1 (i.e. in bb-hosts: 10.0.0.1 fake-host # noconn). Regardless of what host (or fake host, if you do that), you will need to create a new RRD trend to that host. You can create an RRD graph (by modifying hobbit-graph.cfg) that gets its data from multiple RRD files. These files are usually created in a directory for each host, and I don't know if you can just create a symlink to those or not. But assuming that works, you should be all set in creating a single graph that plots all the other data using a single scale. I think you would want to add the following to hobbitserver.cfg: GRAPHS="<whatever is already there>,custom-postfix" And then hobbit-graph.cfg would look something like this: [custom-postfix] . . . DEF:hosta:HostA.rrd:AVERAGE DEF:hostb:HostB.rrd:AVERAGE . . . I have tried creating a new client in the data files ans symbolically linking the other RRD files into its data directory, but cannot persude the graphs to appear in the trends web page.

[hobbit] Soon-to-be 4.3.0
by gumby3203＠gmail.com 06 Nov '07

06 Nov '07

Henrik, It's been a while since we've heard any news about 4.3.0, as far as features go. From the various threads around here, it sounds like it's going to be pretty feature-packed, and if that's the case, I can see why this release is taking a while to come out. I was just wondering if you could provide some info on some of the more important / major changes and additions that can be confirmed in the 4.3.0 release? There is one or two features I'd like to see, but perhaps some of the other features you have planned will be enough for what I need.

[hobbit] Hobbit CONN questions
by Chris.Morris＠RWEsystemsUK.com 06 Nov '07

06 Nov '07

Well it depends whether you are using fping or hobbitping - try reading the man pages, which can be accessed from the Help menu of the web page. This tells you how many pings, what happens when the first ping fails, the timeout etc etc and yes it is configurable. > -----Original Message----- > From: johan.boye at latecoere.fr [SMTP:johan.boye at latecoere.fr] > Sent: Tuesday, November 06, 2007 2:43 PM > To: hobbit at hswn.dk > Subject: [hobbit] Hobbit CONN questions > > Hello again, > > I'm polished a Hobbit installation.

Hobbit CONN questions

Hello again, I'm polished a Hobbit installation. I would like to know how the Hobbit server handle the "conn" step. I guess it's a couple of ping, isn't it ? How it works when a first ping doesn't not respond? How many packet are sent each time? What is the time-out? Can we configure it?

Two BBDisplays, one collaboration
by josh＠imaginenetworksllc.com 05 Nov '07

05 Nov '07

What I am trying to do is have two BBDisplay servers. The first one being our main one - monitors our network equipment and things - and a second one that lives on the customer's network and pings APs, Switches, etc. I have setup this in bb-hosts on the main one: page HIXX Holiday Inn X X group-compress <H3><I>Access Points</I></H3> 1.2.3.4 host.com # noconn group-compress <H3><I>HIDM Hardware</I></H3> 2.3.4.5 host2.com # noconn Reason for the noconn is that these are all private IPs, accessible only by the customer's LAN. These configuration match those of the customer's bb-hosts (with the exception of noconn, of course =) I then went into the customer's server/etc/hobbitserver.cfg and changed it as such: BBDISP="0.0.0.0" BBDISPLAYS=" 10.59.1.119,MAINSERVERPUBLIC" I have also tried it without quotes When I set this neither BBDisplay has anything on the www pages, they're completely blank! Once I switch it to BBDISP="$BBSERVERIP" # IP of a single hobbit/bbd server BBDISPLAYS="" It works perfectly fine on the customer's server, but the main one is display blank (obviously =) Please let me know where I went wrong.

[hobbit] big brother replacement
by Mark.Deiss＠acs-inc.com 05 Nov '07

For a vanilla BB environment, you can have multiple BBDISPLAY entities but the recommendation is that there is only one BBNET entity. A BBNET server that is generating the pings out to the clients will be sending the ping results to all of the BBDISPLAY entities (as defined on the BBNET host). If you have multiple BBNET entities that ping the same servers, you will be sending duplicated results as far as the individual BBDISPLAY servers are concerned (the connection messages will be renamed to the host being pinged). To support multiple BBNETs in a non-race environment requires additional coding to carefully direct the BBNET results to not trip over each other. The default behavior is to pump them out to whatever BBDISPLAY is listed - you get the race conditions when you want all the BBDISPLAY servers to monitor all of the BBNET hosts (i.e. want BBNET to send their client-side tests to the BBDISPLAY entities - this will result in the BBNET poll messages going out to all the BBDISPLAY entities also). It's doable, hacked the heck out of the BB code base years ago to support three separate BBDISPLAY/BBNET servers that provided redundant monitoring over a client base and over each other. The goal in this case is the BBNET directs its status messages to only a defined group of BBDISPLAY servers - that will only have the one source of BBNET message traffic. The rest of the BBNET's tests would be allowed to go to a wider distribution of BBDISPLAY servers. These other tests would be keyed to the BBNET's server name so there would not be a race or conflict conditions occurring on the BBDISPLAY servers. The BBNET race condition may seem minor - but then think about what is going on with any RRD database entries - you would be updating if from all the BBNET entities in a given time window. Resulting trends can get really bizarre if the BBNET polls are originating from different network segments with different response times. Bad times from one segment getting masked in the trends due to updates occurring from another segment etc. Main difference in the commercial version of BB over the BTF version is that they added support for encrypting the communications from the clients to the servers. I would place some value on that as some sites are running external tests that are sending sensitive client information to the BBDISPLAY boxes. There may be a difference in the level of included documentation - but who reads the documentation anyways..... Maybe Mr. Croteau and Mr. MacGuire will do a LBO and take BB private again. -----Original Message----- From: Sloan [mailto:joe at tmsusa.com] Sent: Thursday, November 01, 2007 8:05 PM To: hobbit at hswn.dk Subject: Re: [hobbit] big brother replacement Josh Luthman wrote: > That would be relative to Hobbit's bbtest I believe - someone correct > me if I'm wrong, I'm just guessing here! > > I don't see any reason to think that script wouldn't work with some > variable changes like BBNET=`$GREP BBNET $BBHOSTS | $GREP "^[0-9]" | > $GREP -v "^\#"` but I am not an expert by any means!

Ah, interesting - I always had the feeling that quest didn't do much of anything with the code except put in some verbiage and legal warnings, and tried to push their own proprietary and non linux-friendly stuff and left the bb code base to slowly decay.

strange result in fping by hobbit and fping by yours truly
by dortsen＠gmail.com 05 Nov '07

05 Nov '07

Hi everyone, I've got a somewhat strange issue with fping in hobbit. I've got a list of about 122 terminals that are used for a chipcard payment system. Each one of them has an ip-address and connects to a server to process the payments. Every now and then the terminals loose the connection or whatever, they need to be reset before they can process the payments again on the server. I thought I might use Hobbit to ping all the terminals to see if they still respond to a ping. If they don't reply anymore, they need a reset. I only do a conn test on an ip-address. I use the full path to fping in hobbitserver.cfg, without any extra parameters. When hobbit starts testing the connection, only 14 terminals respond to a ping, but when I execute a fping myself (as the hobbit user) in a shell to the same amount of terminals, I get a totally different result, instead of 14 responding terminals, I get 95 responding terminals with fping! It's not just a lucky shot, I can keep on trying these terminals, the huge difference remains whether I fping them myself or when hobbit fpings them. I'm running hobbit 4.2.0. According to bbtest I have 806 hosts that are pinged, that takes about 26 seconds to complete. To complete all tests (954), it takes about 47 seconds. Does anyone have a clue why specifically these terminals have such a difference in hobbit ping and a ping performed by myself? I can't explain it, and it doesn't seem like a timeout (latency) issue to me either. Thanks in advance, Br. Dennis
