fping error code 4 [Resolved]
by everett.vernon＠gmail.com 17 Jan '13

17 Jan '13

Hi all Well, it's been 48 hours now, without an incident. Seems that not all fpings are created equal. I did install the OpenCSW fping when I installed Xymon. The the install script defaults to using the last instance of fping it finds, and looks for the OpenCSW fping last. >From build/fping.sh echo "Checking for fping ..." for DIR in / /usr /usr/local /opt /usr/pkg /opt/csw do if test "$DIR" = "/"; then DIR=""; fi if test -x $DIR/bin/fping then FPING=$DIR/bin/fping elif test -x $DIR/sbin/fping then FPING=$DIR/sbin/fping fi done I would have expected this to default to the OpenCSW version of fping. So what went wrong? My recollection of the install is poor, but It is possible that I ran the configure script as Xymon user, and had only set the suid bit on /usr/local/sbin/fping, meaning that test -x $DIR/bin/fping would have failed for the OpenCSW version, defaulting to the fping in /usr/local. Of course, the script would have reported no errors, because it would have met all requirements. An executable fping. *Solution *: Make sure that Xymon is using the OpenCSW fping, as defined by the FPING= variable in ~/server/etc/xymonserver.cfg *Prevention 1 *: When running configure at install time, use the --fping option to explicitly define which fping to use. *Prevention 2* : Make sure you set the suid bit on ALL instances of fping.

wildcard /regex for PROC in analysis.cfg file?
by Paul.Root＠CenturyLink.com 16 Jan '13

16 Jan '13

Can I do something like: HOST=foo PROC "/path/to/perl .* MyPerlScript.pl" 1 1 red ? Basically, I've got a command run by a custom version of perl, and the command line has a bunch of -I arguments put in by the wrapper of the software packages. I can't not have them, it's the way the vendor built the system. But I also don't want to get a red alarm if someone is grep/vi/more/lessing the file. Or is there another way? Paul.

Starting Xymon via init script no environment variables
by Michael.Beatty＠sherwin.com 16 Jan '13

16 Jan '13

I've got an init script that is starting up the xymon client. It starts, and runs, however it doesn't appear to have any access to any environment variables. If I restart the client from a shell, it takes off and runs fine. I've got echo statements in the init script to display some of the environment variables I need, and they are displaying fine at boot time. It just seems that xymon doesn't have access to them when it is running. What has me really confused is that I'm even exporting the variable from a file directly from the xymon script. For example, in the init script, I 'echo $HOST' The host name shows up in the log I have a perl script that clientlaunch calls, I have a variable "my $host = $ENV{"HOST"}. I am printing the "HOST" variable out to the log file when the script runs. If I start the xymon client from a shell, the HOST variable prints out. However, it doesn't print out (just a blank) if the xymon client starts via the init script. -- Michael Beatty

Save Trends as PDFs
by Nick＠Pettefar.com 16 Jan '13

16 Jan '13

Hi, is there a way of saving the trends pages for each server as a PDF? Preferably without the settings box at the top. I have tried several Firefox Add-Ons but they either don't display the graphics, just links, or crash. I tried installing the xymonton.org PDF Reports stuff but I think it must be quite old as the instructions talk about a menu_items.js file which doesn't exist. It would be good if it could be generated automatically each month too. Regards, Nick Pettefar

Xymon users, Xymon Version: 4.3.10 OS Version: Ubuntu Server 12.04.1 LTS Can anybody advise me on how to make xymon server(xymon.sh) start automatically on server reboot? I also need to do the same for clients(runclient.sh).

Custom test with NCV
by mailinglists＠websitemanagers.com.au 15 Jan '13

15 Jan '13

I have written a couple of custom tests, and they are reporting data back to xymon, which is then using the NCV to import into a RRD file. However, sometimes the values wrap around, and then my graph gets a massive negative value showing. How can I tell hobbit to setup the RRD file such that the minimum valid value is 0, which would at least discard the single wrong value... Currently, one value has a minimum of -6M while all other values are between 0 and max of 119000 but I can't see anything on the graph because of the single massive negative value? I did actually think rrd was smart enough to notice wraps like this, but perhaps I've created the RRD wrong, or specified something incorrectly?

Hi all Anybody seen something like this? Execution of '/usr/local/sbin/fping -Ae' failed with error-code 4 /usr/local/sbin/fping: select : Invalid argument Error I see when xymonnet page goes red. At the same time, all conn tests go white. Happens briefly every few hours. No obvious pattern, but at least once a day, sometimes twice.

syntax for analysis/alerts
by Ejones＠egov.com 15 Jan '13

15 Jan '13

I'm trying to get alerts working for a group of servers that have *soldb* in the server name but I can't seem to figure out the right syntax. Can anyone give me a hand with a *whatever* syntax? What I have at the moment is LOAD 70 100 HOST=%^/soldb*/ , and it isn't working. ---------- Elizabeth Jones Unix Administrator - NIC, Inc. 25501 West Valley Parkway, Suite 300, Olathe, KS 66061 email: ejones at egov.com<mailto:ejones at egov.com>
