DNS failures causing "runtime longer than time limit"
by jlaidman＠rebel-it.com.au 11 Sep '17

11 Sep '17

Hi I'm running Xymon v4.3.10 on Linux, and I'm quite sure it's compiled with c-ares support. I have 12 new DNS servers that were added to Xymon about one month ago. All of my server entries in hosts.cfg have "testip". The tasks.cfg runs xymonet with "--dns-timeout=3". The hosts entries look like so: 10.10.10.1 dnshost1.example.com # testip dns=NS:example.com,SOA: example.com About a week ago, connectivity to all of these servers failed, and at the same time, the xymonnet run time jumped from less than 15 seconds to about 330 seconds, so about 315 seconds extra. The xymonnet page says 295 seconds is taken up by DNS tests. If the increase in time taken is about 315 and is entirely due to the 12 servers failing, then each failed server is adding about 26 seconds to the total run time. I don't think this should be happening like this. With two DNS checks per server, the DNS checks should be taking 6 seconds each to time-out, not 26. If I run xymonnet with "--timing --no-update" and specify only one hostname, I can view the results and the timing. This shows that the ping check gets reported after about 3 seconds, and then the DNS tests are executed and take 26 seconds total. My naiive assumption was that when a server failed a ping (and didn't have "noclear" defined in hosts.cfg) then the network checks would be skipped. On re-reading the man page for hosts.cfg, it dawned on me that a failed ping simply suppresses failed test /results/, but doesn't stop the tests from being run. So the real problem is that the "--dns-timeout=3" is not being taken into consideration by xymonnet. If I run xymonnet with "--debug" it tells me: 1900 2015-06-03 12:02:20 ares_search: tlookup='example.com', class=1, type=2 1900 2015-06-03 12:02:20 ares_search: tlookup='example.com', class=1, type=6 1900 2015-06-03 12:02:20 Processing 0 DNS lookups with ARES 1900 2015-06-03 12:02:46 Finished ARES queue after loop 423 This is peculiar. Why would it say "processing 0 DNS lookups" when there are two lookups to test? Could this be because xymonnet hasn't actually been built with ARES support and I didn't know it? Is there a good way to tell? If I add "--no-ares" I get the same results perhaps suggesting a lack of ARES support. On the other hand, if I add "timeout:3" and "attempts:1" into resolv.conf, I also get the same results. If I run "nm /path/to/xymonnet | grep gethostby" it returns "ares_gethostbyname". Just for fun, I compiled Xymon v4.3.21 and ran the xymonnet binary from there, with no change in behaviour. I also tried removing the "--dns-timeout" option so that it defaults to 30 seconds, but still no change - 26 seconds for two DNS tests. So, I'm not really sure what the problem is, but xymonnet certainly isn't behaving as I would expect. Cheers Jeremy

MAGMA XYMon Web GUI Admin Now Available!
by sanderson＠CORNETSER.com 07 Jan '16

07 Jan '16

Henrik and Fellow Xymoners, Just for you I have pushed off any real work for today just to get you all a first release of MAGMA the XYMon Web GUI Admin. MAGMA is an add-on web GUI for managing Host, Groups and Alarms on a XYmon 4.3 or newer system. You can find MAGMA at http://www.squidworks.net/magma/ There you will find the description, screen shots and features of MAGMA along with the link to download the source package. It requires MySQL and PHP5 and is very simple to install. All supporting information is included in the tarball. How does it work? --------------------------- It stores all alarm and host/group configs in the SQL database and rewrites the Host.cfg, Analysis.cfg and Alarms.cfg files causing the XYmon system to update its tests and pages based on the changes in these files. It will overwrite the files each time a host is added or edited making the process of updating automatic. To get the full benefit of MAGMA you should place all hosts in "central" mode, although this is not required, without it your management is somewhat restrictive (external test management only). In Central mode you get full management features for all tests. If you have any questions or need some help just send me a email @ sanderson @ squidworks.net Cubert 8-) Aka Shannon Anderson

xymon hostdata module going rogue
by Scot.Kreienkamp＠la-z-boy.com 14 Dec '15

Hi everyone, I have a xymon server running 4.3.21 that seems to be accumulating processes like these: hobbit 28430 0.0 0.0 0 0 ? Z 12:50 0:00 [xymond_hostdata] <defunct> hobbit 28435 0.0 0.0 0 0 ?

Z 12:50 0:00 [xymond_hostdata] <defunct> It seemed related to drop messages, so I did a test.

Bug in Xymon? This is on RHEL5, xymon 4.3.21. Thanks!

downtime globally
by dito74＠gmail.com 09 Nov '15

09 Nov '15

I've been using old BB 1.08 and now XYMon, I'm trying to migrate downtime rules but I am not very successful with it. The test that I need NOT reporting on weekends are NOT network tests, they are custom ALC that written on the agent folder and forwarded to the xymon server. Can I only use Downtime for Network tests? Right now now I have this line, but I am still getting alerts on weekends 10.51.0.203 bosutil.domainname.com # smtp DOWNTIME=ALC1:5:2300:2359:check_op_con,ALC2:5:2300:2359:check_op_con,ALC1:0:0000:1200:check_op_con,ALC1:6:0000:2359:check_op_con,ALC2:0:0000:1200:check_op_con,ALC2:6:0000:2359:check_op_con,mq:0:0300:1000:snapshots Gab

Migrating away from SourceForge?
by lists＠benjamindsmith.com 12 Sep '15

12 Sep '15

With all the brouha and SourceForge now loading malware into installers, I wonder about the viability of SourceForge. Is there a plan to migrate to something more stable? At the very least is there a backup of the project for when they bite the dust? Relevant info here: http://www.reddit.com/r/linuxadmin/search?q=sourceforge

Custom 60 second interval test still has 5 min interval graph
by Scot.Kreienkamp＠la-z-boy.com 27 Aug '15

27 Aug '15

Hey everyone, I created a custom test and RRD definition because I wanted to reduce the interval time on a few graphs from 5 minute resolution to 1 minute. I got the data to be logged once every minute, which I verified is hitting the RRD. The problem is that when I view the graph it's still got a resolution of 5 minutes. Here's the partial RRDTool dump:  <row><v> 1.0033333333e+01 </v></row>  <row><v> 1.0550000000e+01 </v></row>  <row><v> 5.6333333333e+00 </v></row>  <row><v> 7.3166666667e+00 </v></row>  <row><v> 7.5000000000e+00 </v></row>  <row><v> 6.2500000000e+00 </v></row>  <row><v> 7.5500000000e+00 </v></row>  <row><v> 9.3333333333e+00 </v></row>  <row><v> 5.2666666667e+00 </v></row>  <row><v> 7.0666666667e+00 </v></row>  <row><v> 6.4000000000e+00 </v></row>  <row><v> 6.4000000000e+00 </v></row>  <row><v> 1.3000000000e+01 </v></row>  <row><v> 9.2000000000e+00 </v></row>  <row><v> 3.4650000000e+01 </v></row>  <row><v> 5.7200000000e+01 </v></row>  <row><v> 5.0283333333e+01 </v></row>  <row><v> 4.4100000000e+01 </v></row>  <row><v> 4.1500000000e+01 </v></row>  <row><v> 2.4500000000e+01 </v></row>  <row><v> 1.2000000000e+01 </v></row> So the data is getting logged every 60 seconds. It's also rolling up to the 5 second, etc, values. Here's the line from xymonserver.cfg: SPLITNCV_cpustat="*:GAUGE:180:0:100" #Configure for 60 second intervals, range of 0-100 Here's the lines from rrddefinitions.cfg: [cpustat] -s 60 RRA:AVERAGE:0.1:1:120 RRA:AVERAGE:0.5:5:576 RRA:AVERAGE:0.5:30:576 RRA:AVERAGE:0.5:120:576 RRA:AVERAGE:0.5:1440:576 RRA:MAX:0.1:1:120 RRA:MAX:0.5:5:576 RRA:MAX:0.5:30:576 RRA:MAX:0.5:120:576 RRA:MAX:0.5:1440:576 Here's the graph definition: [cpustat] FNPATTERN ^cpustat.(.+).rrd TITLE % CPU usage YAXIS Percent DEF:p at RRDIDX@=@RRDFN@:lambda:MAX LINE2:p at RRDIDX@#@COLOR@:@RRDPARAM@ GPRINT:p at RRDIDX@:LAST: \: %5.0lf (cur) GPRINT:p at RRDIDX@:MAX: \: %5.0lf (max) GPRINT:p at RRDIDX@:MIN: \: %5.0lf (min) GPRINT:p at RRDIDX@:AVERAGE: \: %5.0lf (avg)\n I had read that RRDTool should use the lowest resolution available, which is 1 minute for this RRD. So why are the graphs not going less than 5 minute intervals when zooming in? Any ideas? Thanks!

query-frontend (CLI) for `clientlog`, `xymondboard` and `xymondlog`
by thomas.eckert＠it-eckert.de 17 Jul '15

17 Jul '15

Brothers, currently I’m building a fronted for the various query-commands that can be sent to `xymond`. It is still in it’s early stages but I found myself using it daily already. So others may benefit too. It’s named `xymonq` (“xymon query”). Two examples may give a basic idea: 1. Get a list of hosts on page `dc1`: Traditionally this looks like this: $ xymon 127.0.0.1 "xymondboard page=dc1 test=info fields=hostname" With xymonq $ xymonq -P dc1 -L 2. Get disk information this group of hosts: $ for my_host in $(xymon 127.0.0.1 "xymondboard page=dc1 test=info fields=hostname"); do echo “HOST=$my_host" xymon 127.0.0.1 "xymondlog $my_host.disk" done And again the short version with xymonq: $ xymonq -q clientlog -P dc1 -s df More information and download here: http://www.it-eckert.com/software/xymonq/ <http://www.it-eckert.com/software/xymonq/> Feedback welcome! All the best, Thomas
