More Newbie questions.. sorry in advance..

Hi All, Did some of the research on this already and have some ideas but I would like a more concise list of directories to backup when I backup my CentOs 5 box running the Hobbit Moinitor. I do have a "full backup" that I actually made a script for that connects me to a windows box that is being backed up to tape and dumps a nice bz2 file there. What I'm looking for is the incremental or data directories that I should be backing up daily (I figured /etc) but want to know of any other places that I should be backing up my server on a daily basis. Here is the tar command that I run for a full backup once a week: "tar cvpjf "$backup_location/$backup_name" --exclude=/proc --exclude=/lost+found --exclude=/mnt --exclude=/sys /" And if someone knows of anything more I should be adding to the excludes that would also help. The server is pretty much a monitoring box running Hobbit monitoring my sites and servers and OpenNMS to monitor my switches and firewalls. I'm doing research now on cron to get these to fire off by themselves not me manually running the scripts Thank you Henrik and contributors for the great software! And thank you all for the great responsiveness and great advice!! Thank you, Rafal Roginela

hobbitlaunch segfault / timewarp happend again

Hi Henrik, in january I reported a segfault with hobbitlaunch/timefunc.c. You quickly provided a patch...

Question about host listed in bb-hosts more than once
by waa-hobbitml＠revpol.com 21 Mar '08

21 Mar '08

Hello Hobbit list! I have written some custom scripts that are designed to poll a NUT server (network ups tools - http://www.networkupstools.org/ ) and get the values for battery charge %, battery voltage, AC input voltage, AC output voltage and finally UPS load % for one or more UPSes that the nut server is monitoring. Since I am getting five additional columns (bat-charge, bat-voltage, in-voltage, out-voltage and ups-load), I want the stats of the UPSes to be on a different page than the rest of the stats on the servers page to limit the number of additional columns which apply to only one server. In bb-hosts I have: (please forgive word wraps on some of these lines) page Servers Servers group-except / ntp|bat-charge|bat-voltage|in-voltage|out-voltage|ups-load|hobbitd|bbd|bbgen|bbtest|files Linux Servers ...other servers... 10.1.1.1 dns.domain.tld # CLIENT:dns NAME:dns prefer bbd dns ntp ssh / http://dns.domain.tld Then, for the UPS status page, I have: page UPSes UPSes group-only bat-charge|bat-voltage|in-voltage|out-voltage|ups-load 0.0.0.0 dns.domain.tld # CLIENT:dns NAME:"UPS Monitor" noconn I have noticed that if I list the IP address and name of the dns server twice, hobbit complains in the logs about it and explains that strange things might happen. Fair enough... So I added the "prefer" option to the dns server line with the IP, and set the ip of the second instance to 0.0.0.0 The issue I am seeing is that while all my custom UPS status reports work as do their related rrdtool graphs, the NAME:"UPS Monitor" option does not appear to work and the UPS page has one server line labeled "dns" which is the name of the server that is running the UPS monitoring scripts. I have also tried removing the CLIENT:dns option from the 0.0.0.0 server line to no avail. I realize that this is only a minor cosmetic issue, but it can be confusing or misleading to the end users since even though the dns server is running the scripts, the results it is reporting really pertain to one or more UPSes on one or more OTHER servers. Is there a way to do this? Have I missed something simple? Thanks for Hobbit, and thanks for any help on this... -- Bill Arlofski Reverse Polarity, LLC

[hobbit] Restarting hobbit server

The web server ( generally apache) which serves out the web pages? _____ From: Manocchia, Robert [mailto:Robert-Manocchia at IDEXX.com] Sent: Wednesday, March 05, 2008 11:39 AM To: hobbit at hswn.dk Subject: [hobbit] Restarting hobbit server The hobbit server hardware was switched from one virtual server to another newer box. The nodename and IP address remained the same. I brought down the hobbit client and hobbit server on the box and halted it. It was then switch to the new hardware. I restarted the hobbit server and hobbit client. Now I cannot get the web page to appear.

Checking process longevity
by Colin.Coe＠woodside.com.au 20 Mar '08

20 Mar '08

Hi all I'm trying to work out how I can get hobbit to alert me when a process has existed for more than n seconds. This is important as we sometimes have NFS problems that cause processes such as df to hang due to stale mounts and I'd like tp pick these up sooner rather than later. Any ideas on how to implement this? Thanks CC NOTICE: This email and any attachments are confidential. They may contain legally privileged information or copyright material.

Hobbit client columns not showing up on hobbit server machine
by Rafal.Roginela＠AmeriCashLoans.net 20 Mar '08

20 Mar '08

Hi, Great software!!! It has launched me into the world of Linux at the office instead of just for play and fun. But I have an issue with the server not showing it's health statuses. It does not report things like disk and memory info, it does provide things like: bbd, bbgen, bbtest, conn, graphs, hobbitd, http, info. Sorry for a question that is truly a newb but I ran out of ways to search for the answer and couldn't find anything that helped. Thank You, Rafal

Windows version of a fully functional bb command
by bewhite＠fellowes.com 20 Mar '08

20 Mar '08

Hi all, I know I saw a thread earlier about a fully functional bb for windows and that someone had ported the hobbit bb code to windows and got it working. I, for the life of me, can not now find that thread. I'm interested in a windows bb executable so I can write a quick DOS bat file that my windows guys can run to place a windows server into maintenance mode. Anybody have a windows bb executable and/or such a script?

How to alert on Summary reports
by Dave.Whitehouse＠talis.com 20 Mar '08

20 Mar '08

Hi, Is it possible to alert on a summary from a remote hobbit server? I have two servers, 1 in the office with a modem attached for SMS alerts and one out at one of our Co Location sites that sends summary reports to the first one. I've tried configuring an alert on the summary reports with a few different alert lines but can't seem to get it to works. I though if I use COLOR="red" then that should work but no joy. Any one done this ? Thanks Dave.
