[hobbit] cgi bb-hostedit script released
by brent.mccrackin＠bell.ca 02 May '05

02 May '05

An update to this... I can see in the code that it should support group-only, but it doesn't appear to work very well. I haven't been able to find any changes yet that will make it work, though - but my regex isn't as sharp as most people's seem to be :-) Everything else appears to work well with BB1.9c/BBgen 3.5, though! --- Brent B McCrackin UNIX Systems Specialist - Bell Sympatico Brent.McCrackin at Bell.ca PH: 416-353-0692 "Serenity through viciousness." -----Original Message----- From: McCrackin, Brent (6002384) Sent: May 2, 2005 12:38 PM To: 'hobbit at hswn.dk' Subject: RE: [hobbit] cgi bb-hostedit script released Here's another one... You do not appear to have any support for the "group-only" directive. This works like group-compress, but you list exactly which services to display for the hosts included in the group. EG: group-only test1|test2|test3|test4|test5 Servers Group This facilitates having hosts with more tests than comfortably fit on a single line in the display to be split among multiple lines, or which have services that only apply to a specific page grouping. An example I have is a database server with a dozen different databases each monitored by bb-moracle, but producing their own dot. I split the server to have an 'OS-Tests' line and a 'Database-Tests' line in the display. This is performed with group-only. --- Brent B McCrackin UNIX Systems Specialist - Bell Sympatico Brent.McCrackin at Bell.ca PH: 416-353-0692 "Serenity through viciousness." -----Original Message----- From: Schwimmer, Eric E *HS [mailto:EES2Y at hscmail.mcc.virginia.edu] Sent: April 29, 2005 11:45 AM To: hobbit at hswn.dk Subject: RE: [hobbit] cgi bb-hostedit script released Okay, here's the patch: http://www.nerdvana.org/eric/files/bb-hostedit-hostdupe-patch The tarball has been updated; new users don't need to download this patch. -Eric -----Original Message----- From: Schwimmer, Eric E *HS [mailto:EES2Y at hscmail.mcc.virginia.edu] Sent: Friday, April 29, 2005 9:31 AM To: hobbit at hswn.dk Subject: RE: [hobbit] cgi bb-hostedit script released Hi Thomas, thanks for helping test out the script :) >1.

[hobbit] PCRE regular expressions (help?)
by KauffmanT＠nibco.com 02 May '05

02 May '05

I thought about the escapes -- but PCRE doesn't seem to like this any better: PCRE compile of NORRDDISKS='^\/oracle\/.+?\/(sapdata|data|orig|mirr)' failed (and the original needs to have a double \\ in each spot, to escape the escape, for the shell export).

apache perf monitoring leaves http test purple
by tgeorgoulias＠mcclatchy.com 02 May '05

02 May '05

I set up Apache performance monitoring today and it's pretty cool. apache.rrd is filling up with data, graphs are working fine and displaying in my trends page, yada yada yaday. I did run into a problem though, my http column remains purple even though I didn't configure Hobbit to monitor a specific url. This is the entry in bb-hosts: 0.0.0.0 hostname.domain.com # "apache=http://1.2.3.4:80/server-status?auto" LARRD:*,vmstat:vmstat|vmstat3|vmstat4|vmstat5,apache:apache|apache2|apache3 The http column remains purple, and clicking through to the status page shows a blank purple page with no data whatsoever and an empty "HTTP Response Times Last 48 Hours" graph. What can I do to get rid of this status, w/o having to set up a http test that points to a proper website? Tom

BBGen doesn't seem to share that implicit assumption (as far as I've seen, anyway), but its duely noted and I can work around that in my configurations. It would be nice to allow subpages under different pages to be able to have the same names, though, since they appear to map directly to the directory structure. --- Brent B McCrackin UNIX Systems Specialist - Bell Sympatico Brent.McCrackin at Bell.ca PH: 416-353-0692 "Serenity through viciousness." -----Original Message----- From: Henrik Stoerner [mailto:henrik at hswn.dk] Sent: May 2, 2005 12:42 PM To: hobbit at hswn.dk Subject: Re: [hobbit] cgi bb-hostedit script released On Mon, May 02, 2005 at 12:06:55PM -0400, brent.mccrackin at bell.ca wrote: > > Subpages should be able to have the same names if they exist under > different pages, and should also be able to have the same names as pages > regardless of where they are. Using the same subpage name is not recommended. I wouldn't be surprised if something broke because of that - there's an implicit assumption in Hobbit that pagenames are unique.

[hobbit] some larrd issues on hobbit 4.0.3 rc1
by KauffmanT＠nibco.com 02 May '05

02 May '05

IIRC, the vmstat graphs were among the very first items to be set up in larrd, and he was learning rrd at the time. Now don't hold your breath, but I will pass the conversion tool along to you whenever I get it working. It's just not going to be all that high on my list. This is the year we swap out virtually every AIX system we've got because the lease is up, and the fun starts early next month.

I looked at the one remaining BB server I have, and it seems you're right - LARRD really does sort the datasets alphabetically by name when it sets up the vmstat RRD file. It seems it does this only for the vmstat data. > Short term, I'm going to change do_vmstat.c, while I research writing > some code to re-work the rrd xml (too many changes and too many rrds to > try it by hand).

Dont forget that this is a regexp - I think you meant '/oracle/PRD/sapdata.*' with a dot before the asterisk.

OK -- Re-ordering the AIX and linux entries in do_vmstat.c and copying the vmstat rrds from my other BB system fixed the problem. Thanks for the help. And the do_disk.c patch is MUCH appreciated! I'm down to nine disk graphs on my R3 db server (and it has two clones that will be affected as well) Thanks! Tom

[hobbit] cgi bb-hostedit script released
by brent.mccrackin＠bell.ca 02 May '05

Just taking a look at this myself. Using it with bb19c and bbgen 3.5 (not hobbit) so here's some insane testing :-) It seems to work, aside from the fact that I have a subpage which happenes to have the same name as a page elsewhere in the config file, but the directories created do not conflict anyway, since subpage directories are created under the page directory they belong to. This produces an error message in the script - "Subpage previously defined". Subpages should be able to have the same names if they exist under different pages, and should also be able to have the same names as pages regardless of where they are. --- Brent B McCrackin UNIX Systems Specialist - Bell Sympatico Brent.McCrackin at Bell.ca PH: 416-353-0692 "Serenity through viciousness." -----Original Message----- From: Schwimmer, Eric E *HS [mailto:EES2Y at hscmail.mcc.virginia.edu] Sent: April 29, 2005 11:45 AM To: hobbit at hswn.dk Subject: RE: [hobbit] cgi bb-hostedit script released Okay, here's the patch: http://www.nerdvana.org/eric/files/bb-hostedit-hostdupe-patch The tarball has been updated; new users don't need to download this patch. -Eric -----Original Message----- From: Schwimmer, Eric E *HS [mailto:EES2Y at hscmail.mcc.virginia.edu] Sent: Friday, April 29, 2005 9:31 AM To: hobbit at hswn.dk Subject: RE: [hobbit] cgi bb-hostedit script released Hi Thomas, thanks for helping test out the script :) >1.
