[bug?] Crash of hobbitsvc.cgi on trends column display
by cgoyard＠cvf.fr 29 Jan '07

29 Jan '07

Hi Henrik, Yesterday I upgraded my hobbit server to take advantage of the all-in-one corrections, plus the "split-ncv" feature (have a peek in your spambox to see my message about this :)). I then found a bug that did not show up on the test host, so I rolled back. Since then, hobbitsvc.cgi segfaults when I click on the trends column (renamed _graphs in my setup) : http://monitor/hobbit-cgi/bb-hostsvc.sh?HOST=somehost.dom&SERVICE=_graphs Here's gdb output : #0 bbh_find_item (host=0x8088210, item=BBH_DISPLAYNAME) at loadhosts.c:160 #1 0x0804e652 in rrdlink_text (host=0x807f980, rrd=0x80881f0,wantmeta=HG_PLAIN_LINK) at hobbitsvc-trends.c:120 #2 0x0804eb99 in generate_trends (hostname=0x80769d8 "somehost.dom") at hobbitsvc-trends.c:288 #3 0x08049feb in do_request () at hobbitsvc.c:216 #4 0x0804aeb6 in main (argc=1, argv=0xbf935594) at hobbitsvc.c:518 just before the crash, I have : i=0 host->elems gives "Cannot access memory at address 0x0" item=BBH_DISPLAYNAME bbh_item_key[item]="NAME:" 160 while (host->elems[i] && strncasecmp(host->elems[i],bbh_item_key[item], strlen(bbh_item_key[item]))) i++; Can it come from a missing "something" in the configuration ? Can it crash because of corrupted rrd files ? I continue my investigations, but you sure can help :). [oh, I found another small bug, not severe at all: when running hobbitsvc.cgi from the command line, it segfaults if SCRIPT_NAME is not set. Maybe it should set SCRIPT_NAME to a sensible default or at least exit grcefully] -- Charles Goyard - cgoyard at cvf.fr - (+33) 1 45 38 01 31

[hobbit] Purples, all non-green view

Hobbit regular expression problem in macros
by jonescr＠cisco.com 09 Jan '07

09 Jan '07

I am again being bitten by regex problems. I am able to reproduce it with the following entries in hobbit-alerts.cfg: $IGNORE_HOSTS=%prod-web-(1|2|3|4|9|10|11)$ HOST=$IGNORE_HOSTS service=* IGNORE If I then check the "info" column of a host that is *not* supposed to be ignored, such as prod-web-12. It shows that it is indeed ignored. This is a serious problem as I have already missed alerts for some production hosts because of this problem. According to pcretest (Henriks recommended method of testing a Hobbit regex), there is nothing wrong with the regular expression that I am using: $ pcretest PCRE version 6.6 06-Feb-2006 re> /prod-web-(1|2|3|4|9|10|11)$/ data> prod-web-12 (*correctly not matching*) No match data> prod-web-19 (*correctly not matching*) No match data> prod-web-10 (*correctly matching*) 0: prod-web-10 1: 10 From the above tests you can see that prod-web-12 does not match the regex when using pcretest, yet Hobbit is matching it for some reason. A possible work-around could be to not use a regex at all, such as $IGNORE_HOSTS=prod-web-1,prod-web-2,prod-web-3... but that is not really a solution if you have hundreds of hosts, and my main point is that regular expressions are not working as they are documented. I've also tried other undocumented ways of using the regex, including: No hosts matched at all $IGNORE_HOSTS=%prod-web-(1|2|3|4|9|10|11)$ HOST="IGNORE_HOSTS" No hosts matched at all $IGNORE_HOSTS="%prod-web-(1|2|3|4|9|10|11)$" HOST=$IGNORE_HOSTS All hosts match (both web-12 and web-11) $IGNORE_HOSTS=prod-web-(1|2|3|4|9|10|11)$ HOST=%$IGNORE_HOSTS If anyone else can verify or reproduce this, it would be helpful in at least convincing Henrik to add it to the list of things to fix in the next version. I honestly hope that it's not a problem with Hobbit and instead something I am doing wrong - if so please enlighten me. -Charles

Contact to Henrik
by wolfgang.wutz＠siemensvdo.com 02 Jan '07

02 Jan '07

Hello everybody, sorry for spamming the mailing list, but I'm quite desperate. Currently I'm doing my diploma thesis and part of it is setting up and customizing a monitoring environment using hobbit. Due to the fact, that my Prof wants me to write s.th. about the hobbit system architecture, I tried to reach Henrik personally by mail, but unfortunately got no reaction. Probably the spam filters blocked my messages. So Henrik, if you read this, please tell me a way to get in contact with you. Thanks for your time. Wolfgang

Client information not showing up
by gregor＠hostgis.com 31 Dec '06

31 Dec '06

Hi, all. I'm getting the old familiar problem that the client info is not showing up in the report. Ideas? The hostname on the client matches the hostname in the bb-hosts: 208.96.11.149 build64 # ftp ssh https://208.96.11.149:10000/ root at build64:/usr/local/hobbit/client# uname -n build64 Port 1984 on the client is reachable from the server: # telnet 208.96.11.149 1984 Trying 208.96.11.149... Connected to 208.96.11.149. Escape character is '^]'. The client is running: hobbit 30455 0.0 0.1 2948 464 ? Ss 10:20 0:00 /usr/local/hobbit/client/bin/hobbitlaunch --config=/usr/local/hobbit/client/etc/clientlaunch.cfg --log=/usr/local/hobbit/client/logs/clientlaunch.log --pidfile=/usr/local/hobbit/client/logs/clientlaunch.build64.pid hobbit 30456 0.0 0.2 2692 552 ?

Is there a way I can manually connect to the client to fetch a status report? Is there a logfile that contains useful error messages? -- HostGIS Cartographic development and hosting services 707-822-9355 http://www.HostGIS.com/

Solaris Inte U3 11/06 vmware with hobbit server on 2GB flash drive
by tj_yang＠hotmail.com 31 Dec '06

I create this for training,learning and testing purposes. Too bad I can't distribute the vmware image. Hopefully when OpenSolaris is more mature, this small project can migrate to OpenSolaris and be made available for public download.

dns query load?

I'd like to monitor the number of dns queries hitting my external DNS servers. there is a bb script that supposedly does this - bb-dns-load, but I'd like to know if anyone has got it working with the hobbit client. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281, CNX Austin Energy http://www.austinenergy.com

[hobbit] More than just green/red for HTTP cont= tests?
by gumby3203＠gmail.com 29 Dec '06

29 Dec '06

Maybe I missed it, but I couldn't find this question anywhere in the hobbit mailing list archives... Is there a way to have multiple HTTP cont= tests for a single web page, that are for different content checks for a different status color? I currently have Hobbit monitoring several webpages which themselves are like mini-Hobbit display pages. Depending on the status of those pages, I'd like hobbit to display either green, yellow, or red. Currently, the cont= test only checks if the content exists; if it does, it's green, otherwise, it's red. What I'm thinking is, is there a way to say something like cont[=column];url;[expected_data_regexp];[alternate_data_regexp] Where if "expected_data_regexp" is matched, the status is green. If it isn't matched, it tries to match "alternate_data_regexp". If *that* is matched, the status is yellow. If neither are matched, the status is reg. Also, let me know if you all think this is going a little beyond the scope of Hobbit. Perhaps I should be doing this test with an external script, rather than using an http cont= test. The only problem would be, I'd have to make the script be able to read and parse an http page... Gary B.

Any answer will be appreciated! statusbbgen.sh also needs to be twiddled to use the hobbit executables.
