Debugging issues with bb-histlog.sh on 4.3.0
I've some "random" failures on bb-histlog.sh, viewing items in the bb2 event log. Some work as expected, but some when clicked appear to do nothing. Hitting the URL for that (say http://den2sch17/hobbit-cgi/bb-histlog.sh?HOST=den1ws063&SERVICE=nfs&TIMEBUF...) with curl shows a zero-length reply. Checking the Apache error log shows "Premature end of script headers: bb-histlog.sh, referer: http://den2sch17/hobbit/bb2.html". I have found no core files left behind.
How is the best way to debug this problem, with no core files? Is there a good method to run this (or I suppose more specifically, hobbitsvc.cgi) under the debugger and feed it the request so I can tell why it is silently failing?
Thanks in advance for any suggestions. -Alan
I am experiencing same problem but it is on a 4.2.0 server. If you like, we can work together to debug this issue. This bug is listed on my hobbit deployment todo list .

Well, I have mixed luck running under GDB... looking at the code, saw it was trying to get the CGI info from the environment so set some environment variables to fake up enough CGI environment to get it to run. But mostly wound up getting segfaults in expand_env on the HTMLCONTENTTYPE stuff.
But I stumbled upon something that fixed my problem -- but not sure why. I edited the cgi-bin/bb-histlog.sh file, and added "cd /tmp" before the meat of the script. For some reason, I now seem to have no issues. -Alan

Perhaps that ought to be "cd $BBTMP" instead?? Keep all Xymon stuff in one place.

BBTMP is not defined when this script runs...
Following is my debugging of my hobbit server implementation(using slightly different paths). bb-hostsvc.sh has two lines of code.
- ". /etc/opt/hobbitserver42/hobbitcgi.cfg"
- "exec /opt/hobbitserver42/bin/hobbitsvc.cgi $CGI_SVC_OPTS"
$CGI_SVC_OPTS variable got declared in hobbitcgi.cfg as following
CGI_SVC_OPTS="--env=/etc/opt/hobbitserver42/hobbitserver.cfg --no-svcid --history=top" and in hobbitserver.cfg, BBTMP is declared also.
So I don't see why declaring BBTMP can help. but I did go ahead and re-declared BBTMP variable in bb-histlog.sh. The premature error message still showing in apache error_log file. And I do see a core file under cig-bin and file command shows it is from hobbitsvc.cgi command.
core: ELF 32-bit MSB core file SPARC Version 1, from 'hobbitsvc.cgi'
I am using Sun's compiler without -g option, thus recompiling with -g is needed to proceed with dbx command.

Well, guess you're mileage varied... Using BBTMP without setting it wasn't an option, since it'd expand to blank. Do know it helped me, with no good reason why. Unfortunately, as of today, I'm no longer in a position to continue debugging it. -Alan
Greetings,
I have successfully configured the "post" http monitor to login to a website using a form. However, I don't think this monitor has the ability to "log out" like Sitescope for example and thus the end application server ends up with a lot of idle logins and eventually exhausts the connection limit. Is there any process to have hobbit do an additional check/post on the "log off" button after the initial login and content check (if successful)?
Thanks, Tom
Typically the way a log out is started is by clicking a link. Could you not just wget or curl the URL?

I think 4.2 has post, but I don't know when it first appeared. I never used it because the servers I was hitting often had weird redirects that were best handled by a script. Ralph Mitchell

I've added a quick and dirty monitor that might be of some use to someone here: http://xymonton.trantor.org/doku.php/monitors:winupd
At the moment its very basic in that it only checks for pending reboots required as a result of windows updates applied to a windows client. This has been useful here on site as sometimes updates are applied to production servers but downtime is not alllowed.. This monitor serves as a reminder to reboot to finish applying the updates
If you think you can enhance the script please do. My vb is poor..
Padraig Lennon
Here is a vbscript I use to test for needed updates. I did not put any checks in for the existence of bbwin. I run my script from a Windows task and so I don't use the file system object to write the file-I just redirect stdout to a file in my bbwin's tmp directory. Feel free to modify as you see fit.

From: Lennon, Padraig [mailto:Padraig.Lennon at pioneerinvestments.com] Sent: Friday, June 26, 2009 3:52 AM To: hobbit at hswn.dk Subject: [hobbit] Windows update check monitor added to the Shire
I've added a quick and dirty monitor that might be of some use to someone here: http://xymonton.trantor.org/doku.php/monitors:winupd
At the moment its very basic in that it only checks for pending reboots required as a result of windows updates applied to a windows client. This has been useful here on site as sometimes updates are applied to production servers but downtime is not alllowed.. This monitor serves as a reminder to reboot to finish applying the updates
If you think you can enhance the script please do. My vb is poor..

This is *not* fully regression tested (it works for me); but, here is the code using a disconnected record set for sorting. Also, IE8 does not format the table the same way Firefox 3 does, and I gave up trying to make it do it. So, you will likely want to adjust the styles to fit your needs.

Well, I found an error... (grin). I needed to check for a recordset with no records in it-no Windows updates needed! Sorry for the inconvenience. Here's the updated code...

If you're using the bb-hosts "post", I think you'd have to do a second post, or possibly a "cont" check on the logout url. I don't know if cookies would be transferred from one check to the next, which might be a problem. I think you'd also get another column in the output. I almost always used external scripts to do a substantial number of web site checks, so I would simply insert an extra step to do the logout. I generally reported yellow if the logout failed...

Greetings,
I have successfully configured the "post" http monitor to login to a website using a form. However, I don't think this monitor has the ability to "log out" like Sitescope for example and thus the end application server ends up with a lot of idle logins and eventually exhausts the connection limit. Is there any process to have hobbit do an additional check/post on the "log off" button after the initial login and content check (if successful)?
Thanks, Tom
