Hi All, Hopefully someone can help with this issue. hobbitd_rrd keeps crashing and popping up as red on my xymon installation. I am running 4.3.0-0 beta 2.

Graphs stop working on pages, but still work on Trends
by David.Stuffle＠anthem.com 02 Sep '10

02 Sep '10

Hi, I just set up a new Xymon 4.2.3 install and I have AIX clients reporting to the Xymon server. The individual graphs, such as disk, memory, etc., show up fine on the pages at first, but it seems around 48 hours, the graphs stop showing, BUT they still show fine on the "trends" colums and are being updated. This happens for all hosts including the Xymon server. If I delete the RRD files, they get recreated and start working, but then after 48 hours, they stop again. They always show fine on the trends column. They only graph that continues to work on the individual test view is for the CPU column. I don't see any relevant info in the logs. I'm using RRD tool 1.4.4. Anyone know what could be causing this? For example: The url it sends for the memory column is this - which doesn't work: http://xymon/xymon-cgi/hobbitgraph.sh?host=adc13001u&service=memory&grap h_width=576&graph_height=120&disp=adc13001u&nostale&color=green&graph=ho urly&action=view The url it sends for the memory graph in the trends column is this - which does work: http://xymon/xymon-cgi/hobbitgraph.sh?host=adc13001u&service=memory&grap h_width=576&graph_height=120&first=1&count=2&disp=adc13001u&graph=hourly &action=view Removing the "nostale" from the first url makes it work if it's entered in a browser alone. But, the CPU has the nostale in it and still works. ???

PROBLEM IN BBPROXY WITH MULTIPLE BBDISPLAYS
by simobimou＠hotmail.com 02 Sep '10

02 Sep '10

Hi all !! I'm using a bbproxy that forward messages to two bbdispalys servers , everything works well until the day when one of my bbdisplays went down, I was thinking that the bbproxy will continue to forward messages to the second bbdisplay server but it wasn't the case. When i say the bbdisplay is down i meen that the server crashs and is unreachable because when i just stop xymon on one of the bbdisplays server the bbproxy still send information to the second one. So the problem is produced when one of the bbdisplays is unreachable. Anyone has any solution, idea, suggestion ....? Thank you in advance!! Momo

FW: [xymon] TS - bb-hosts problem (SOLUTION)
by d.tom.schmitt＠L-3com.com 31 Aug '10

Hope this helps someone else in the future. After much testing and comparing: It seems that before you can use the 0.0.0.0 entries, you must have the actual host entry with the IP Address on the line in bb-hosts. It must be declared FIRST (before any of the 0.0.0.0 entries) in the bb-hosts file. GOOD: ===== 128.192.10.10 device.abc.com # comm group-compress aaa ... 0.0.0.0 device.abc.com . . . group-compress bbb ... 0.0.0.0 device.abc.com BAD: ==== group-compress aaa ... 0.0.0.0 device.abc.com 128.192.10.10 device.abc.com # comm. group-compress bbb ... 0.0.0.0 device.abc.com I automatically generate list for the Windows Admins with all of their servers listed below their name ICON. This way the Admins can keep up just their list of servers. The script runs every day early in the morning. I have up to 5 - 0.0.0.0 occurrences in the bb-hosts file.

The 0.0.0.0 entries are so that you can show the tests on other web pages in xymon. I do this on over 100 devices so the 0.0.0.0 entries should not be causing the problem. I am still at a loss where it is getting the message. I should be able to have one actual test entry with the IP address on the line and Multiple 0.0.0.0 entries that are associated with it. Why is just this one entry having a problem???? Do I have to remove all the entries for this hosts including the Xymon DB entry and add them back in again?

As indicated by the error, this may cause strange results. I'm not sure what your point is about the 0.0.0.0 ip. With no TESTIP tag, the ip will only be used if hostname lookup fails. And used or not used, you have four instances of the hostname in bb-hosts, which can give strange results. Or maybe I'm not reading your post correctly.

Disable alerts if $SOME_SERVICE is down
by take＠nerd.fi 31 Aug '10

31 Aug '10

Hello! I've been trying to find a way to ignore alerts if i.e. xymon's local connection is down. Currently our xymon -server sends alerts from every host if the local connection goes down. Unfortunately in our current setup that's quite possible scenario and things are going to the direction where the boy cried wolf too often. So, how I could restrict alerts so, that if local connection (or any other service for the matter) fails, alerts won't trigger? -- Take

This is not correct. This listed in the bb-hosts file: 0.0.0.0 cswflex4.csw.L-3com.com 128.170.31.14 cswflex4.csw.L-3com.com # conn 0.0.0.0 cswflex4.csw.l-3com.com 0.0.0.0 cswflex4.csw.l-3com.com Will result in that host being ping tested 4 times. 0.0.0.0 means do a DNS lookup for the IP address, then ping test it. I think your IP "128.170.31.14" will be ignored as well, DNS will be used first, but test that theory yourself. What you want is to add the "noping" option at the end of 3 of these entries, and add a "prefer" option to the line you want xymon to work with. You also need to check your DNS entries for hosts, 382 lookup failures sounds like something to investigate. If you have around 100 unique hostnames in your bb-hosts file, this stat shows that you have around 1002 total lines. DNS lookups for all ;) DNS statistics: # hostnames resolved : 975 # succesful : 573 # failed : 382 # calls to dnsresolve : 1002 Craig

I tried to do a 'drop hostname', could there be a duplicate in the Xymon data base? If so, how do you remove the bad one so you don't loose the history being gathered by the client on the Windows server. The client is the big brother client.
