"recent" icons set
by frederic.mangeant＠steria.com 08 Feb '05

08 Feb '05

Hi Henrik I'd like you to comment on a modification I made to bbgen, relative to the "recent" gifs set. By default, when using with "--recentgifs", a different icon is used if a page color is less than 24 hours old. I've modified loaddata.c to use the "recent" gifs set if a page color is less than 1 hour old; the modification is attached. Perhaps it would even be possible to include a new option : - "--recentgifs=1-day" to keep the current behavior - "--recentgifs=1-hour" - etc. Many thanks in advance. Regards, -- Frédéric Mangeant Steria EDC Sophia Antipolis

by Etienne.Roulland＠cvf.fr 08 Feb '05

08 Feb '05

Hi everybody, i'm trying to set up an hobbit server with both big brother & sister clients. I don't have problem to get the rrd graphs from BigB client but big sister doesn't seems to be "hobbit aware"... I get this for the disks test : N/A 9.2GB 7.7GB 1.5GB 84% / N/A 9GB 6.6GB 2.4GB 74% /home So i get : 2005-02-07 18:36:13 RRD error creating /usr/local/stow/hobbit//data/rrd/mybox/disk,N/A.rrd: creating '/usr/local/stow/hobbit//data/rrd/mybox/disk,N/A.rrd': No such file or directory I don't understand why i get an "N/A".. Is somebody ever tried this setting ? And did it work ? Regards, -- Etienne Roulland <Etienne.Roulland at cvf.fr>

[hobbit] COLOR keyword in alerts
by blysik＠shutterfly.com 07 Feb '05

07 Feb '05

> OK, it's a bug that triggers when you have a color-setting followed by > some other rule. > > Patch is attached, it is also available at http://www.hswn.dk/beta/ Great. Looks like the patch does the trick. Question: If I have COLOR=red,purple and RECOVERED, will I get recovery alerts for machines which go into 'yellow'? Obviously this isn't desired behavior. Thanks. -- Bruce Z. Lysik <blysik at shutterfly.com> Operations Engineer

disabling the conn test on a per host basis
by kevin.grady＠gmail.com 07 Feb '05

07 Feb '05

I have a set of hosts that are not availabled via the conn test. I attempted to disable the conn test for each by adding noconn after # in the bb-hots file. However, the conn test column still shows up and the conn test shows a red status until eventually the status changes to purple. Am I missing something with the steps to disable a conn test for a host? Thanks Kevin

[hobbit] Apache tag

That was excellent advice! It is working nicely now. Thank you sir! Kevin _____ From: Charles Jones [mailto:jonescr at cisco.com] Sent: Sunday, February 06, 2005 11:28 PM To: hobbit at hswn.dk Subject: Re: [hobbit] Apache tag Importance: Low Okay, first you must make the indicated addition to your apache httpd.conf (or you can make a hobbit.conf in apaches conf.d directory). Then, you must restart apache for the change to take effect (/etc/init.d/httpd restart). Then, manually test the server-stats url to make sure it's working, by using your browser and going to http://your.server.com/server-status?auto <http://your.server.com/server-status?auto> (you can also go to http://your.server.com/server-status/ <http://your.server.com/server-status/> to get some nice extended apache performance info). You should get back something like this: Total Accesses: 131577 Total kBytes: 796036 CPULoad: 1.0401 Uptime: 21595 ReqPerSec: 6.09294 BytesPerSec: 37746.7 BytesPerReq: 6195.16 BusyWorkers: 43 IdleWorkers: 13 Scoreboard: RR__RWR___RR_R_RR_RRRRRRRRR_RRRRRRR__RRR_RRRRCRRRRR_RRRR.................... ............................................................................ ............................................................................ ............................ Now, assuming you are getting back the server-status info, time to make sure your bb-hosts is correctly configured to collect and graph the data. Heres what I have in mine: 1.2.3.4 my.server.com # conn ssh http://1.2.3.4 <http://1.2.3.4> apache=http://1.2.3.4/server-status?auto <http://1.2.3.4/server-status?auto> LARRD:*,apache:apache|apache1|apache2|apache3 >From what you said of your setup, I'm guessing your only problem is using the wrong url for the apache tag (you used "apache=http://192.168.1.25/hobbit/ <http://192.168.1.25/hobbit/> " which just won't work - that's the kind of URL you would use for the http tag).

No Subject On Mail Alerts
by Andy＠zespri.com 07 Feb '05

07 Feb '05

The email alerts I get from my hobbit user have no subject line. This makes it tricky to get a quick idea of what's up - I obviously have to open every email to see the service and color. Is it possible to get the subject as per BB? I guess I could change over from MAIL to SCRIPT and format it myself, but I'd thought I'd ask what everyone else was up to first :-) Cheers, Andy. ##################################################################################### This email is intended for the person to whom it is addressed only.

Hobbit 4.0-RC1 available
by henrik＠hswn.dk 06 Feb '05

06 Feb '05

The first release-candidate of Hobbit 4.0 was uploaded to hobbitmon.sourceforge.net a few minutes ago. This fixes several serious bugs, especially in the alert handling module where use of the DURATION specification in beta6 would delay an alert for 24 hours, and the handling of macros was very broken. A number of platform compatibility issues have been resolved, especially on NetBSD and AIX. The data collected for vmstat- and netstat-reports has changed, and this unfortunately means that the vmstat- and netstat-RRD files in RC1 are incompatible with previous versions, and also with files generated by LARRD. You must delete files in the old format, or collection of these data will fail. The larrd-data.log and larrd-status.log files will contain error-messages if this happens. Some joker disabled all of the tests on my demonstration site. So I decided to move the "Enable/Disable" and "Acknowledge" CGI scripts to a secured area requiring a login. This is now part of Hobbit and can be enabled during configuration. Several other minor bugs and improvements, the full list is below. Thanks to everyone testing Hobbit - there are now more than 100 people on the mailing list, which is much more than I had expected. I hope you'll try out this version, so any remaining bugs can be squashed. Regards, Henrik Changes from beta-6 -> RC-1 --------------------------- * NOTE: The netstat RRD file layout has changed. You must delete all "netstat.rrd" files, or your data collection will fail. Sorry, but the old LARRD format cannot cope with reality, where some systems report packet counts, some report byte counts, and some have both. * NOTE: The vmstat RRD file layout has changed, for data collected from Linux-based systems. You must delete all such "vmstat.rrd" files, or the data collection will fail. There were several incompatible formats of linux vmstat RRD files - now they all use the same format. * Hobbit should now work on AIX, and possibly other platforms that enforce strict X/Open XPG4 semantics for the ftok() routine. If you were seeing messages like "Could not generate shmem key..." or "Cannot setup status channel", then these should now be fixed. Thanks to Chris Morris for being patient with me while I struggled with the finer details of SVR4 IPC. * A new "--test" option was implemented for hobbitd_alert. Running "hobbitd_alert --test HOSTNAME SERVICENAME" will print out the rules that match the HOSTNAME/SERVICENAME combination, so you can see what alerts are triggered. (Note: man-page is not updated with this info yet). * Macros in hobbit-alerts.cfg were broken. Completely. * Specifying time-values in hobbit-alerts.cfg as "10m" was interpreted as "10 months" instead of "10 minutes". Since minutes is much more likely to be useful, the support for "months" and "years" was dropped, and "10m" now means minutes. * Specifying any kind of duration meant that the alert would not happen until 24 hours had passed (and the alert still was active). * Two new keywords in the hobbit-alerts.cfg file: STOP on a recipient means that Hobbit stops looking for more recipients after the current one has matched. UNMATCHED on a recipient means that this recipient only gets an alert if no other recipients got an alert (for setting up a default catch-all rule). * A simple syntax for "all hosts" is now "HOST=*" in hobbit-alerts.cfg * Configuring the Hobbit URL's as a root URL - "http://host/" - now works, and yields correct links to the menu, the GIF- files, and the documentation. * The Enable/Disable script (maint.pl) now picks up the menu correctly. * The "configure" script now allows you to select a second CGI directory for administration scripts (the ack-script and enable/disable script). This second directory is access-controlled; the default Apache configuration was updated to show how. * The ~/server/starthobbit.sh symbolic link was not being re-generated if the file already existed (on some platforms). * The hobbit-tips.html file is now generated during installation, so it has correct links to the icons. Previously it assumed that the icon-files had been copied to the www/help/ directory. * vmstat data for the "I/O wait cpu time" on Linux is now being collected. Linux RRD data-formats made identical across the various formats that are in use; this means any existing vmstat.rrd files from Linux systems must be deleted. * Support for NetBSD 2.0 in vmstat and netstat RRD handler. * HTTP authentication strings are now URL un-escaped, so you can use any byte-value in the username and/or password. * The info-column now includes the current address assigned to a DHCP host. * A new "noinfo" tag can be used to suppress the "info" column on selected hosts. * bbhostgrep no longer segfault's if you do not use the BBLOCATION environment setting. This kept some extension scripts from working. * If every single network test failed, bbtest-net could loop indefinitely. Seen on NetBSD. * If the number of available file-descriptors (ulimit -n) was exceeded, bbtest-net would loop forever. Seen on NetBSD. * When running http-tests via a proxy that requires authentication, the authentication info could not contain a ":" or a "@". The authentication info is now un-escaped using the normal URL decoding routine, so these characters can be entered as %XX escaped data (e.g. to put a "@" in the password, use "%40"). * LDAP tests now try to select LDAPv3 first, and fallback to LDAPv2 if this is not possible. Some newer LDAP servers refuse to talk v2 protocol. * Memory debugging was accidentally enabled in beta6 - it is now disabled.
