Help with GROUP and alerting
by shea_greg＠emc.com 23 Jul '07

23 Jul '07

Hi all, I'm having some trouble either understanding how to use groups or my syntax is wrong, or maybe even a combo of both. Like most other organizations, the sysadmins don't want to be alerted for disk usage of database and application groups. Some of our larger applications can have DBAs responsible for their disks, 2 different apps-dev groups responsible for their disks, and finally the sysadmins. I tried a 2 disk scenario and a couple of different ways to see if I could notify on separate disks and I'm not getting the desired results. Is anyone else doing this??

Alerting table in the info screen
by shea4th＠comcast.net 23 Jul '07

23 Jul '07

Hi all, Is there supposed to be an "Exceptions" portion of the alerting table when viewed from the info button? Kind of like the way BB has it? This way here, at a glance, not only can I tell what services are being alerted on, but I would also like to know what's configured NOT to alert on. For instance (excerpt from hobbit-alerts.cfg) HOST=myhost SERVICE=disk,memory,msgs,network,procs MAIL somebody at someplace.com FORMAT=TEXT REPEAT=30 RECOVERED EXSERVICE=cpu,files,netstat,ports,vmstat Thanks -Grs- Gregory R Shea EMC Corporation

Greetings, I'm working with Galen on getting this set up correctly, and here are the problems I'm running into: First, I've set up the site specific pages as described, i.e. I was using the "custgroup blah blah' moniker in the bb-hosts file, but have now moved to having bbgen call a stripped down version of the bb-hosts file of only the machines I want the special group to see. i.e. in hobbitlaunch.cfg [cust-display] ENVFILE /usr/local/hobbit/server/etc/hobbitserver.cfg CMD /usr/local/hobbit/server/ext/cust-display.sh LOGFILE $HOBBITCLIENTHOME/logs/bb-display.log INTERVAL 1m And the cust-display.sh file contains: #!/bin/sh BBWEB="/hobbit/cust" BBHOSTS=/usr/local/hobbit/server/etc/bb-hosts-cust BBSKIN="$BBSERVERWWWURL/cust/gifs" BBMENUSKIN="$BBSERVERWWWURL/cust/menu" BBHELPSKIN="$BBSERVERWWWURL/cust/help" # Hobbit URL prefix for the online help files. BBREPURL="$BBSERVERWWWURL/cust/rep" # Hobbit URL prefix for the Hobbit availability reports BBSNAPURL="$BBSERVERWWWURL/cust/snap" # Hobbit URL prefix for the Hobbit snapshots $BBHOME/bin/bbgen --pageset=cust --template=cust $BBHOME/www/cust/ I have created cust_header/cust_footer files in the "/server/web" directory, and everything creates fine in the "http://site/hobbit/cust" web link. I have enabled apache to only allow the special users to visit the site via http://site/hobbit/cust, and not have access to /hobbit. I've also enabled them to run things in the cgi-bin script directory. This works fine for just showing them the main page with a status. I want them to be able to run metric/snapshot reports on specific machines only. The problem is the menu options allow them to see all the servers in the environment, not just the ones in their specific bb-hosts-cust file. I've even attempted to manually create a cgi-bin directory under the /hobbit/cust location and edit each cgi sh script (adding some environ vars for the BBSERVERCGIURL etc), but to no avail. I guess my big question is where does a script such as hobbit-hostgraphs.sh grab its list of servers to show in the choice pane? If I can restrict these scripts to only report on the servers in the bb-hosts-cust file, I believe I'll have this set up like a charm. Also, can I set up custom templates for files other than header and footer? I.e. if I want to keep the menu option when a person clicks on CPU, then the graphs_footer file which is a symlink to bb_footer gets pulled in instead of a custom graphs footer. I get the access denied to the menu due to my apache restrictions on /hobbit since it's pulling the URL "/hobbit/menu/menu.js" instead of my /hobbit/cust/menu/menu.js link Thanks, Tom On Thu, 2007-07-19 at 14:41 -0400, Galen Johnson wrote: > We are tryingto set up site specific pages to allow different groups to view only their specific servers (and limit the tests they see).

[hobbit] [Hobbit] Try to do an instant http test
by sbrabez＠ixis-cib.com 23 Jul '07

23 Jul '07

Hi Henrik, So, I use the command line like you said, bbcmd bbtest-net --checkresponse --no-ares --debug msgipd01, the output is http://rafb.net/p/uQI6pB30.html For my configuration, I use the "include" directive in the bb-hosts file, and put the follow line into my included file : 0.0.0.0 server01 # noconn noping http://server01.domain.net:8000 http://serverd02.domain.net:8006 http://serverd02.domain.net:8007 h ttp://server01.domain.net:8008 (on the same line) More over, I have any questions: - For personal reason, the server appears twice in my bb-hosts file configuration, it maybe cause a problem ? - It's possible after a drop, no more metric status will be returned (because one day, I use the bb(1) to drop) or it's just to purge log (like the old binary bbrm) ? There is a way to reactivate the status check I forgot to do ? - There is a limit of URL for http test in the bb-hosts file configuration ?

[patch] split-ncv and maximum value tracking
by cgoyard＠cvf.fr 21 Jul '07

21 Jul '07

Hi all, here is a patch that provides two new features to the NCV graph backend. It answers to a request I did on August 2nd (subject: "Dynamic or Split NCV"). - split-ncv : Lets you store an ever-changing set of data on a status column basis. Say, you want to keep track of who is accessing a database. It works by creating a rrd file per ncv line instead of packing a lot of DS in a single rrd file. I use it to keep track of tomcat session number per context, harddrive temperature, database connexions, and a whole bunch of other things, such a the repartition of loaded classes on a jvm (useful to find memory leaks). - trackmax : it lets you keep track of the maximum value of a dataset, along with the average. It's useful when the maximum is somehow as significant than the average over time. (say, to track a hard-limited ressource, such as telephone lines). I use it to keep track of the maximum number of busy X25 lines on a specific application. It only works for NCV at the time, but I may add it to other tests. The patch includes the documentation for all this. It applies on today's snapshot and on october' all-in-one. It does not work with the plain release because of a nasty bug in do_ncv.c. Well, here's the patch. Consider it beta, but yet it works on my production server. I strongly hope it will be included in the mainstream hobbit (I don't like maintaining local patches :)).
