[hobbit] bbtest-net output & poll time

Running hobbit on a dedicated server: Dual Xeon 1GHz Compaq ML350, 1.2GB RAM, ultra3 scsi raid5. This is just a temp setup; once we have all the kinks iron out, we'll replace BB on our real test server, which is a little more beefy. I just now tried editing our bb-hosts file to be completely flat (no pages/subpages) and removed everything after the hostnames, but it didn't affect the load time at all. Changing the FPING options in my hobbitserver.cfg to "-i15 -r2 -b12" seems to have helped my ping time quit a bit, though (thanks again, Henrik!) -Eric -----Original Message----- From: olivier at qalpit.com [mailto:olivier at qalpit.com] Sent: Mon 4/4/2005 5:29 PM To: hobbit at hswn.dk Cc: Subject: Re: [hobbit] bbtest-net output & poll time Hi, my test hobbit server has 1500 entry in bbhost (only doing network test for now) and bbtest-net's report says for me : Tests loaded 1112649412.475584 56.090490 that seems awfully high compared to henrik's 4 seconds.. what do you guys have on your servers ?

bbtest-net output & poll time

Hi all, got another few posers: I have a bb-hosts file with 1229 hosts in it, but no TCP (http/ssh/ftp) enabled. In my hobbitlaunch.cfg, I have bbnet configured as follows: CMD bbtest-net --report --ping --checkresponse --dns=ip --concurrency=1500 --dns-timeout=5 --timeout=5 The bbtest output for my hobbit server shows the following snippets: <snip> DNS statistics: # hostnames resolved : 1220 # succesful : 25 # failed : 975 # calls to dnsresolve : 0 </snip> <snip> TIME SPENT Event Starttime Duration bbtest-net startup 1112644638.542264 - Service definitions loaded 1112644638.545180 0.002916 Tests loaded 1112644659.079652 20.534472 DNS lookups completed 1112644659.080039 0.000387 Test engine setup completed 1112644659.089031 0.008992 TCP tests completed 1112644659.089883 0.000852 PING test completed (1229 hosts) 1112644712.816387 53.726504 PING test results sent 1112644713.047301 0.230914 Test result collection completed 1112644713.047324 0.000023 LDAP test engine setup completed 1112644713.047339 0.000015 LDAP tests executed 1112644713.047369 0.000030 LDAP tests result collection completed 1112644713.047384 0.000015 Test results transmitted 1112644713.101506 0.054122 bbtest-net completed 1112644713.104883 0.003377 TIME TOTAL 74.562619 </snip> I thought that the --dns=ip option in the hobbitlaunch.cfg precluded any DNS resolution, but the bbtest output above seems to indicate the opposite. Does anybody know what those DNS tests are the result of? Also, I'm a bit curious as to the chronlogical breakdown of the bbtest events; specifically the "Tests Loaded" section. Does 20 seconds seem reasonable for a bb-hosts file our our size? (I'm trying desperately to get below the 60 second mark :) TIA, -Eric Network Engineer University of Virginia HSCS

I am using the default install of sendmail with my linux distribution (RH 7.2) It is sending out alerts as "hobbit at servername.domain.com. I am getting tired of explaining to every new person what Hobbit is (even though I really like showing them!) I would like to have the alerts go out as something like "system-alarms at servername.domain.com Can anyone tell me if there is a simple way to change the name these alerts go out as? Thanks btw..I am not a sendmail wizardso simple is good.

[hobbit] A few hobbit problems
by EES2Y＠hscmail.mcc.virginia.edu 04 Apr '05

I might have found another, unrelated, problem: When I include any one of the following three lines in my bb-hosts file: 137.54.102.2 healthsystem.virginia.edu # http://healthsystem.virginia.edu/ 137.54.102.2 healthsystem.virginia.edu # http://healthsystem.virginia.edu=137.54.102.2/ 137.54.102.2 healthsystem.virginia.edu # http://137.54.102.2/ The bbgen process seems to hang. The 'healthsystem.virginia.edu' page fails to appear in the appropriate menu. None of the menu pages update, although individual test pages (such as a conn test for a switch) update appropriately. Furthermore, the bbgen test for my hobbit server sends this message: - Program crashed Fatal signal caught! (though you can only see it by viewing the bbgen test; the parent page doesnt update). -Eric

Your eventlog has an entry from a host that is not in the bb-hosts file; these are ignored by the normal eventlog shown on the bb2 page, but the CGI script tried to include them with fatal consequences. I've attached a patch to fix this. To apply, save the patch to /tmp/eventlog-crash.patch, then cd hobbit-4.0.1 patch -p0 </tmp/eventlog-crash.patch make make install # as root Regards, Henrik

This is a sure sign of the "bbgen" task crashing while generating the new webpages. You should find a core file from it in the ~hobbit/server/tmp/ directory (or occasionally in ~hobbit/data/logs/), so do the same thing that you did with the eventlog problem: cd ~hobbit/server gdb bin/bbgen tmp/core gdb> bt and send me the output.

[hobbit] securing access
by Robert.Taylor＠HendrickAuto.com 04 Apr '05

04 Apr '05

There was a post a few days back with an LDAP configuration. I was able to change a few things around a get that to work with our MS Active Directory to validate usernames/passwords for access on a RH EL 3.0 box. Here is the config for my Apache server. It effectively let's anyone access from the internal 10.x.x.x network and then requires a valid username/password for anyone accessing via the Web. <Directory "/var/www/html"> AllowOverride None Order Deny,Allow AuthType Basic AuthName "<Something to display in dialog>" AuthzLDAPEngine on AuthzLDAPServer <IP Address of LDAP Server>:389 AuthzLDAPUserKey sAMAccountName AuthzLDAPBindDN <valid LDAP Username for binding to server> AuthzLDAPBindPassword <LDAP password for username above> AuthzLDAPUserBase dc=<something>,dc=<something .com, .local, .net etc.> AuthzLDAPUserScope subtree Deny from all Satisfy any Require valid-user Allow from 10. </Directory> Standard disclaimer would be that I am no Apache expert and this took me FOREVER to get working right, but it seems to be okay now.

patch for external RRD script
by grossi＠acantho.net 04 Apr '05

04 Apr '05

I have tried to use my own RRD generator with a bash script similar to the one included in the documentation. the problem is that sometimes the input file is overwritten before the bash script is started, i made a simple change in the file do_external.c, and now it seems to work well. Henrik, can you check ?
