/etc/resolv.conf and DNS error (http test)
by Dominique.Frise＠unil.ch 27 Sep '07

27 Sep '07

Hi, We have tried following settings in the Hobbit server's /etc/resolv.conf (Solaris 9) domain example.com nameserver 1.2.3.4 nameserver 1.2.3.5 options timeout:1 options retry:1 While the first and second nameserver are up and running we receive sometimes "DNS error" on http checks like http://www.example.com. Assuming that the first nameserver is not responding within the timeout, the second should be queried by the Hobbit resolver and get the response. Is there something that we are missing?

Request: Adding bb-services entries for mail submission and smtps (587 and 465)
by cleaver＠redwire.net 26 Sep '07

26 Sep '07

The bb-services entry for smtps rightly indicates that smtps does not have an IANA-approved port number, however the "standard" port used as the default for most clients is what's generally run -- port 465. Also, port 587 _is_ a standard for "submission" or "msa"... first time injection of messages via authorized or authenticated SMTP. It would be nice to see both of these supported by default in hobbit's config. A patch to do so is below.

Advice on how to handle HA monitoring
by jonescr＠cisco.com 26 Sep '07

26 Sep '07

We have 2 hosts, HostA and HostB. They are part of an HA cluster via HP ServiceGuard. There is a virtual IP and DNS name of "virtual" that automatically goes to whichever of HostA and HostB is the primary at the time. I am currently monitoring both HostA and HostB via Hobbit. Currently HostA is the primary, and I am doing various PROC checks. Currently on HostB, I am not doing process checks. My problem is, how do I smoothly handle a failover scenario (HostB becoming the primary)? When a failover occurs, all of the procs on HostA are stopped (either by the server crashing, or manualy by ServiceGuard), and the same procs are started up on HostB. I'm trying to think of ways to monitor both hosts, but only monitor procs on the one that is primary. So far the best I can come up with is to run the hobbit clients in local mode, and maybe have the ServiceGuard scripts swap out the config files and restart the Hobbit clients when there is a failover. That would probably work, BUT in this case the Hobbit homdir is also the same (SAN mount) on both machines, so moving or editing a file on one does the same on the other :( Simply shutting down the hobbit client on the non-primary is not an option, as then it would no longer be monitored at all. Any ideas? :) -Charles

NooB questions - Status not Available
by pmcilrath＠marketron.com 26 Sep '07

26 Sep '07

Hi, Im a NooB to Hobbit. I have some Big Brother background which is why I chose Hobbit for a new monitoring project at my company. Im running CentOS 5, and I installed Apache 2, and rrdtool-1.0.50-3.el5.rf.i386.rpm and Hobbit from hobbit-4.1.2p1-1e14.re.i386. The installations all went smoothly, no error messages, I put some hosts in my bb-hosts file and fired up hobbitd. The main page comes up, but when I click on any of the tests icons, instead of getting the current status for that hosts tests, I get a blank page with "Status not Available". However, if I click on "all Non-Green view" from the view menus and look at the tests historically they are all there and can be viewed normally. I checked the files for the hosts in the hist, hislogs and logs directories and they are growing and receiving data from the clients. A ps -ef | grep hobbitd seems to indicate that hobbitd is up and running. I suspect its a permissions thing, but the structure of Hobbit is different enough from BB Im not sure where to look. I am also seeing a couple of odd behaviors in reports that makes me suspect that as well. If I try to run a snapshot report I get a blank page with "Cannot create output directory", and the config report says it cannot contact the Hobbit server. If this is the wrong place for this post, please let me know and I will go where I should. And if anyone has a little patience to help a NooB along for awhile, I will promise to do my time helping other NooBs along when the shoe is on the other foor and support this forum.

No, you should still use devmon for monitoring SNMP enabled devices. At least for the time being - devmon, I think, can do a lot more than snmpcollect right now. > Any tips on usage? > Or it is too early to try it ? It's very early to try this, only do it if you're really adventurous. I only started this Saturday, so it hasn't seen any real testing. Nonetheless, I setup a small test run of it this afternoon, and so far it appears to be working as intended. If you do want to try it out, get the snapshot version which will be available in a couple of hours. The reason for doing this is that our network people are having problems collecting statistics with MRTG. Basically, their MRTG server is extremely overloaded, and besides that they'd rather not have to worry about setting up MRTG and maintaining a website for it. So I was asked if it was possible for Hobbit to handle the ~10.000 datasets they are currently collecting with MRTG. Of course, that was a challenge I had to meet :-) I've chosen to be a bit more thorough than MRTG in the data collection. MRTG by default collects only the in/out byte counts from a device; you can do that with Hobbit's new snmpcollect, but a better choice is to grab the entire set of data present in the "interfaces" MIB. This includes some interesting data, e.g. how many bad packets arrived over the interface, how many were discarded, and what the current output queue length is. snmpcollect uses a configuration file that looks like this: [localhost] version=2 community=public mrtg=2 IF-MIB::ifInOctets.2 IF-MIB::ifOutOctets.2 Main IO # ifmib=2 LAN # ifmib=(eth0) LAN # ifmib=[0:e:a6:ce:d6:85] LAN ifmib={172.16.10.100} LAN So for a host, you define the SNMP version you want to use (currently v1 and v2c only), the community name, and optionally an IP address for it. Then you can request snmpcollect to fetch either a set of data in MRTG form, or you can fetch the entire interface-MIB set of data for a router interface / switch port. There are different ways to define what interface you want the data for - by interface number, description, MAC address or IP. snmpcollect grabs the data and sends it to Hobbit in a "data" message; this is picked up by the current hobbitd_rrd module and put into trend graphs. Right now it just collects the data. I have some ideas to add monitoring so it might trigger an alert if the error-rate of an interface goes up, or the traffic exceeds certain limits (min/max). Nothing definite yet. Oh - and the current snapshot blindly assumes you have Net-SNMP installed; if not, it won't compile. No need to tell me that - I know.
