External scripts thresholds via hobbit-clients.cfg

Ralph, When I removed the DS definition I did get the error message in the log so it looks like it's picking up the line. But it's not doing anything with it. I removed all the logfiles so it would be easy to find any error messages, but ten minutes later and nothing except a few peer not up messages from the restart. Unless Henrik has some suggestions to figure out why it doesn't work I'll probably be forced to make this an external test. Thanks for your help in troubleshooting though, it's much appreciated.

It has a script run by xymon that reads a temperature probe and logs to an rrd. I've just tried this: rrdtool dump 1wire.rrd |egrep -e name -e last_ds -e type <name> Board </name> <type> GAUGE </type> <last_ds>77.79</last_ds> <name> Probe </name> <type> GAUGE </type> <last_ds>35.15</last_ds> and added this to analysis.cfg: HOST=ithilien DS conn 1wire.rrd:Probe >35 COLOR=red "TEXT=Keg temp exceeding &L degrees" I briefly changed the number to 3 and the COLOR to yellow, just to make sure it wasn't having a problem with single digits and colors. You can see in the conn column where the probe temp rose too high. The probe data is graphed under the 1wire column, so it doesn't even matter if the rrd has a different name to the column. When I first added the extra bits, I stopped xymon, then started it. After subsequent changes I did a xymon.sh restart I don't think it's supposed to *need* the restart. You might also try removing the :ds0. That should cause a message like this in a log somewhere: Invalid DS definition at line %d (missing column, key and/or dataset) Don't know what else to suggest, except maybe insert a few more errprintf() lines in the code. Henrik may still chime in with some suggestions too. Ralph Mitchell On Wed, Oct 19, 2011 at 9:59 PM, Scot Kreienkamp <SKreien at la-z-boy.com<mailto:SKreien at la-z-boy.com>> wrote: Quite sure.

If so, I don't get that column. Even if I name it as a column that already exists I don't get any additional info in that column. It's like the lines in analysis.cfg are being totally ignored. I upgraded to 4.3.5 this afternoon also, just in case it might have been something with the version I was running previously. I set debug on all the services I thought might be responsible for this operation and there's no mention of the column or the RRD in the logfiles. Thanks for the help. I've got to be doing something wrong or encountering a bug of some kind, but I'm totally lost as to what it is.

Here's my line: DS Users cmrtgusers.rrd:ds0 >3 COLOR=red "TEXT=Exceeding 30 logged in users" The last value from the rrd was 35, so the line should be hit, but I get nothing. I added debug to all the modules, I've tried several names for the column, I even linked the rrd to another name because it had a dash in the middle thinking the parser might not like that. Still nothing. I also then removed the rrd completely, hoping that I would at least get a line in one of the logfiles indicating a missing rrd. I get NOTHING no matter what I do. What am I doing wrong??? HELP! I've just proved to my own satisfaction that a space between the symbol and the number prevents the number from being read correctly. i,.e. ">15.0" works, but "> 15.0" does not. You can verify the number is being read by inserting &L or &U in the TEXT string: DS Users cmrtgusers.rrd:ds0 >3 COLOR=red "TEXT=Exceeding &L logged in users" You should see "Exceeding 3.00 logged in users". It seems to be OK without or without the decimal, but with a space the number is read as 0.00. If I found the correct piece, the code is in xymon-4.3.3/xymond/client_config.c starting at line 1383 (line 1404 in xymon-4.3.5). The number is converted by atof() at line 1438 (line 1439 in 4.3.5), which is supposed to be able to deal with optional leading whitespace, but apparently that's not happening here. It takes a while for xymon to re-read the analysis.cfg file, so you might want to alter the TEXT string a bit each time you try something, so you know when the update takes effect.

Hi Jeremy The reason I am using /opt/xymon is because I thought it would be a good idea to keep everything related to xymon inside /opt so that I will not have to look into different directories when I am looking for any xymon files. Please see the outputs below. I excluded the commented lines that contained the words 'include' and 'Alias' from the outputs. Output of:grep -i "alias" /etc/httpd/conf/*.conf Alias /icons/ "/var/www/icons/" Alias /error/ "/var/www/error/" LoadModule authn_alias_module modules/mod_authn_alias.so LoadModule vhost_alias_module modules/mod_vhost_alias.so LoadModule alias_module modules/mod_alias.so Alias /icons/ "/var/www/icons/" ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" Alias /error/ "/var/www/error/" _______________________________________________________ Output of: grep -i "include" /etc/httpd/conf/*.conf LoadModule include_module modules/mod_include.so Include conf.d/*.conf AddOutputFilter INCLUDES .shtml <IfModule mod_include.c> Options IncludesNoExec AddOutputFilter Includes html ________________________________________ I will try what you suggested. I will remove the content of xymon-apache.conf from httpd.cond and then I will add an 'include' line in httpd.conf like this: Include /opt/xymon/server/etc/xymon-apache.conf I will try that and report back.

Xymon Server Multihomed
by denis＠crewhub.net 20 Oct '11

20 Oct '11

Hi, I'm searching an easier way to configure my xymon 4.3.5 server other than specifying @IP at each test necessary in hosts.cfg. My configuration is with two IPs. I'm on Debian squeeze. One for the real physical IP and another with an alias (which i try to use with my xymon server). Even if i set a DNS name, a reverse DNS, force the IP in xymonserver.cfg some tests like ssh are not working. My configuration of hosts.cfgwas clear and simple until today, i don't want to complexify it with @1.2.3.4 on all tests necessary. Is there another way to configure it ? At least is it possible to apply it for a complete line or a group ? Kind regards, Denis

external script problem - question
by sholmes42＠mac.com 19 Oct '11

19 Oct '11

Xymonphiles: [Disclaimer: I don't think this is a Xymon problem but my boss thinks it might be and has directed me to ask the list for advice.] Running Xymon 4.2.3, display server is a Solaris box, monitoring a few hundred servers which are mostly RHEL 5, many of them are VMs hosted on ESX VMware. The test is an external script which basically does a 'sudo touch foo' on each file system and waits for it to either return with no problem, or return with an error indicating that the file system is read-only, or after 60 seconds declares that the file system is 'hung'. We had been having problems particularly with the read-only file system problem cropping up on the VMs, which is what prompted the implementation of this test. The problem with the test is that once or twice a day we get a flurry of alerts from a dozen or so servers, all at about the same time reporting that there is a hung file system. Other file systems on the same server are reporting that it takes longer to do the touch than we think it should (e.g. 12 to 25 or even 60 seconds). The alerts all go away the next test cycle. The file systems are on local fiber channel disks (i.e. not NFS mounted). The servers getting the alerts are not all VMs and it is not always the same set of servers that show up. Occasionally we catch a file system that is read-only and we are going to modify the test to not send a panic on the hung file system condition so we don't miss the read-only condition, but we really would like to figure out why we are getting these bursts of hung, or at least very slow writes on file systems and why they come in bursts. Thanks for any insight you might have.

Cannot open directory from tasks.cfg

I've just installed xymon on NetBSD from pkgsrc. 2011-10-14 16:11:20 xymonlaunch starting 2011-10-14 16:11:20 Loading tasklist configuration from /usr/pkg/etc/xymon/tasks.cfg 2011-10-14 16:11:20 Cannot open directory I assume the error is because tasks.cfg contains this: # Include add-on modules. directory /usr/pkg/share/xymon/xymonhome/etc/tasks.d Which doesn't exist. Is there documentation on using / setting up tasks.d? -Tracy

Ubuntu 10.04 apt install hobbit-client

Big problem getting the hobbit-client utility from the default apt-get repo. Why is the home directory of the user 'hobbit' in /var/run/hobbit? Every time the system reboots /var/run gets cleared. Hobbit starts fine but my .ssh/authorized_keys file gets erased and my ssh-tunnel no longer works! What is a way around this .. my entire environment of 12 virtual servers now will break XYMON monitoring for them anytime they servers are rebooted. How can I fix this without reinstalling? tia?

How to setup msgs and file column ?
by Thomas.Weber＠ses.com 19 Oct '11

19 Oct '11

Hi, I am looking for some help due to a problem with the msgs and file column. For some reason I do not get any entry in the msgs or file column. Mainly having no msgs is really a problem for me. On the client (RH Linux 5, XYMON client 4.2.2) in localclient.cfg I have: : DEFAULT : : FILE /var/log/messages SIZE>0 MTIME<600 yellow LOG /var/log/messages WARNING COLOR=yellow LOG /var/log/messages ERROR COLOR=red : : On the server (XYMON version 4.3.4, running on Solaris 10) in client_local.cfg I have: : : [linux] log:/var/log/messages:10240 ignore MARK : : [servername] log:/var/log/messages:10240 trigger WARNING|ERROR : : I checked that the client has access rights to read the /var/log/messages file. On the Webpage I get only "The client did not report any logfile data" Is there anything I miss ? Or do msgs work only in the centralized mode ? Thanks for any help. Thomas
