Hierarchial alerting
by Phil.Crooker＠orix.com.au 30 Mar '11

30 Mar '11

Hi All, I'm just in the process of converting our old big brother monitor to xymon. I had a look at zabbix, nagios, groundworks, and pandorafms and found too many quirks, cruft and gotchas (plus the problem of open core systems). I returned to the bb clones and found xymon is not only active and maintained. I must say Xymon is a well thought out, well executed step beyond big brother, well done, Henrik. Is there a way to have a hierarchy for alerts? For example, say we have a branch office with a print server, file server, router, switch, etc. I have a xymon entry for each (and multiples for each, ie poll the ftp port on the file server as well as just the conn monitoring). If the WAN link to the site dies, I get alerts for all the above, where as I should really just get one alert for the router. Or if the file server dies, I shouldn't get both ftp and file server alerts, just the server. I know this wasn't available for big brother and can't find anything in xymon. Does this exsit and/or has this been considered? For our big brother system, I created a perl script daemon that reads in the allevents log to create a "stateful" table of all monitored items. I also have a text file table of the relationships between the monitored items, using tabs: core_switch wan_router site_router site_switch printer server ftp bbd_host local_server smtp user_subnet_switch printer This table is read into a hashed array, the allevents log file is tailed to keep the state table current and the script awaits queries. When an alertable event comes in, this daemon is queried by the alert subsystem (using another perl script), the daemon checks to see if any parent items are in a red state, if so the alert is discarded. This is effectively just a plugin and could be more efficiently done if integrated into the bbd. In terms of config files, having to maintain two files is not ideal. Currently the host listing and web layout are effectively combined in one file, so adding a hierarchy as above would be tricky. Perhaps a second "#" with the parent following, ie: 1.2.3.4 hostname.domain.com # smtp dns # core_switch.domain.com Anyway, this is just an initial query about this issue. thanks and regards, Phil

Changing Host Header
by tseglard＠wat.tv 30 Mar '11

30 Mar '11

Hello, First of all, I'm using Xymon 4.2.3 J I want to get the Apache performance graphs but to achieve that I need to send a specific host header due to my Apache configuration. This command is working thanks to curl : xymonServer:$ curl -H"Host: localhost" http://prdwatweb016:8090/sstatus If I specify any other host, I couldn't get the Apache status. So my question is : how can I do that with Xymon ? Sincerly, Thomas S PS : oh and I really appreciate the new version, that's so great work. I'm really waiting for this one J

Alternate Pageset for alerts?
by isolderj＠hotmail.com 30 Mar '11

30 Mar '11

Is it possible to build an alternate pageset based on First occurence of the alert and an expiry time. So for example a box alerts on conn it is sent to both the "All Non Green" Page but also to a pageset called "Current Alerts". Then after 30 minutes it's just on the "all non green" but no longer on the "Current Alerts" page. So all alerts on the "current alerts" page expire after 30 minutes and then are only on the "All non green". Is this possible and is there maybe some documentation I can read. I have checked the bulding alternate pagesets and I don't see anything that jumps out at me. Or perhaps there is a way to allow the current alerts to appear on the top of the All non Green page so the most recent alerts are first on the page and therefore the page is not sorted alphabetically. Thanks for any help.

That makes it rather difficult to guess what is happening, since I don't know what code is located at address 0x0806f888 ... Did you compile it yourself or use a pre-compiled binary ? If you could compile it with debugging symbols included that would be much more helpful. With the gcc compiler, make sure the CFLAGS in your Makefile include the "-g" option (it does by default in the Xymon source archive). Regards, Henrik

Hobbit Permission Problem

Hi all, I've got a bit of a problem across a number of machines which I'm having some trouble working out. Basically, the problem is my hobbit user can't display my log files: hobbit at host:/var/log$ cat messages cat: messages: Permission denied However, the user has these permissions/groups hobbit at host:/var/log$ id uid=110(hobbit) gid=110(hobbit) groups=0(root),4(adm),110(hobbit) The directories leading to the file have these permissions: hobbit at host:/var/log$ ls -ld / drwxr-xr-x 24 root root 4096 Nov 19 2009 / hobbit at host:/var/log$ ls -ld /var drwxr-xr-x 15 root root 4096 Nov 19 2009 /var hobbit at host:/var/log$ ls -ld /var/log drwxr-xr-x 14 root root 4096 Mar 29 08:46 /var/log The file has read permissions to the adm group of which we are a member (above) hobbit at host:/var/log$ ls -ld /var/log/messages -rw-r----- 1 root adm 21353 Mar 29 13:27 /var/log/messages Finally, here is all the info I can see on the file: hobbit at host:/var/log$ stat /var/log/messages File: `/var/log/messages' Size: 21353 Blocks: 48 IO Block: 1048576 regular file Device: eh/14d Inode: 4202796 Links: 1 Access: (0640/-rw-r-----) Uid: ( 0/ root) Gid: ( 4/ adm) Access: 2011-03-28 20:21:00.000000000 +1100 Modify: 2011-03-29 13:27:00.000000000 +1100 Change: 2011-03-29 13:27:00.000000000 +1100 I'm running a fairly standard Debian lenny The root user has no problem reading/writing the file/etc.... Any pointers would be appreciated.... Regards, Adam

Using --no-cache
by Tom.Stewart＠landsend.com 29 Mar '11

29 Mar '11

On 4.3.0 has the -no-cache been taken out for the rrd daemons? I have been having issues in testing where I am getting missing data for 5-15 minutes at random times. I have increased my MAX... items in the xymonserver.cfg and have tried to use the -no-cache in tasks.cfg. It currently looks like this on a process status. xymon 27206 27201 0 Mar16 ? 00:00:00 xymond_channel --channel=status --log=/home/xymon/log/rrd-status.log xymond_rrd --rrddir=/home/xymon/data/rrd --no-cache xymon 27207 27201 0 Mar16 ? 00:00:00 xymond_channel --channel=data --log=/home/xymon/log/rrd-data.log xymond_rrd --rrddir=/home/xymon/data/rrd --extra-tests=mpstat,zonestat --extra-script=/home/xymon/server/ext/rrd_data.pl --no-cache xymon 27225 27206 0 Mar16 ? 00:00:02 xymond_rrd --rrddir=/home/xymon/data/rrd --no-cache xymon 27249 27207 0 Mar16 ? 00:00:01 xymond_rrd --rrddir=/home/xymon/data/rrd --extra-tests=mpstat,zonestat --extra-script=/home/xymon/server/ext/rrd_data.pl --no-cache The missing data seems to be affecting the Solaris systems more that the other systems. Any ideas would be great. Thank you, Tom
