Recovery notifications not generated when test goes red->yellow->green?
by hobbit＠elyograg.org 13 Dec '17

13 Dec '17

It appears that if a test goes from the red state, to the yellow state, and then to the green state, no recovery notification is sent. If it goes directly from red to green, then we get a notification. Initial notifications are only sent on RED and PURPLE. We have recovery notifications configured for most tests. Xymon server is 4.3.21, built using makerpm.sh and installed with yum on CentOS 6. I do not know whether our previous version (4.3.14) behaved similarly. It was almost an accident that I discovered the problem at all. Is this expected behavior? If it is, can I change it? Thanks, Shawn

CLASS not working as expected
by steve＠opendium.com 11 Dec '17

11 Dec '17

Under Xymon 4.3.25, I'm trying to use the class attribute to group hosts together by what monitoring and alerting they need. So for each host I have a hosts.cfg line like: 192.0.2.1 somehost.example.com # CLASS:Foo trace ssh Then in analysis.cfg I have: CLASS=Foo PROC this PROC that And alerts.cfg has: CLASS=Foo SCRIPT=blah However, the tests in analysis.cfg are not being applied. If I replace CLASS=Foo with HOST=somehost.example.com they work as expected. Also, CLASS=linux seems to work, which implies that the CLASS: directive in the hosts.cfg is being ignored. As far as I can tell, the messages on xymon's "client" channel don't contain the class name that was specified in hosts.cfg, so xymond_client is using the class that the client sent instead. Other channels, such as "status" do include the class name that was specified in hosts.cfg. Am I misunderstanding how the class is supposed to be used, or is this a bug? -- - Steve Hill Technical Director Opendium Limited http://www.opendium.com Direct contacts: Instant messager: xmpp:steve at opendium.com Email: steve at opendium.com Phone: sip:steve at opendium.com Sales / enquiries contacts: Email: sales at opendium.com Phone: +44-1792-824568 / sip:sales at opendium.com Support contacts: Email: support at opendium.com Phone: +44-1792-825748 / sip:support at opendium.com

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

Hi, this has been reported in Debian at https://bugs.debian.org/828611 ----- Forwarded message from Kurt Roeckx <kurt at roeckx.be> ----- Date: Sun, 26 Jun 2016 12:24:54 +0200 From: Kurt Roeckx <kurt at roeckx.be> To: submit at bugs.debian.org Subject: Bug#828611: xymon: FTBFS with openssl 1.1.0 Reply-To: Kurt Roeckx <kurt at roeckx.be>, 828611 at bugs.debian.org Source: xymon Version: 4.3.27-1 Severity: important Control: block 827061 by -1 Hi, OpenSSL 1.1.0 is about to released. During a rebuild of all packages using OpenSSL this package fail to build. A log of that build can be found at: https://breakpoint.cc/openssl-1.1-rebuild-2016-05-29/Attempted/xymon_4.3.27… On https://wiki.openssl.org/index.php/1.1_API_Changes you can see various of the reasons why it might fail. There are also updated man pages at https://www.openssl.org/docs/manmaster/ that should contain useful information. There is a libssl-dev package available in experimental that contains a recent snapshot, I suggest you try building against that to see if everything works.

extcombo problem
by dave＠collegenet.com 12 Aug '16

12 Aug '16

I have a xymon server running 4.3.0~beta2.dfsg-9.1+deb7u1 receiving reports from a bbnet server running 4.3.17-6+deb8u1 and they are not compatible due to the new "extcombo" reporting. The changelog says that the "extcombo" thing was added in version 4.3.13. Even after disabling "combostatus" in tasks.cfg, xymonnet still uses "extcombo". Without a way to disable it, we're partially broken right now. Any suggestions? Dave Fogarty -- Senior System Administrator CollegeNET.com

SSL/HTTPS enabling on existing Xymon Server
by shekar.raaja＠gmail.com 08 Aug '16

08 Aug '16

Hello Xymon Team, I would like to enable SSL on XYMON Server to support https requests. As I am seeing connection time out errors for HTTPS URL's. Our configuration supports HTTP perfectly fine and for your information it is in production and live, so we don't want to do reinstall of Xymon servers. Rather than is there any configuration changes we can make on existing configs and do the server restart?? Xymon Version we are using Xymon version 4.3.7 I just installed Openssl OpenSSL 1.0.1e-fips 11 Feb 2013 Please let me know if any concerns. Thanks and Regards Raja Shekar

SSH - Make Red if ACTIVE
by freesoftwareservers＠gmail.com 05 Aug '16

05 Aug '16

I have set up XYMon and XYMon - Client successfully today! But I have an interesting situation, I have services like my Routers and esxi servers where I want XYMon to go RED if SSH is ENABLED. It should be disabled for security, can I make it so it runs the other way around then normal? I Apologize if this is written somewhere and super easy, I couldn't find it! PS: I had a hard time getting client to work, if I can make a polite suggestion for the this webpage >> http://xymon.sourceforge.net/xymon/help/xymon-tips.html#noclient Basically that cat /etc/default/xymon-client | grep CLIENTHOSTNAME must match XYMon-Server's /etc/xymon/hosts.cfg. 1.2.3.4 CLIENTHOSTNAME # Extra Params I understand that it is implied in the text, but this might make things much easier to fix for those of us looking to solve the issue of "The client is using another hostname than what is in the hosts.cfg file."

RHEL EXT Script Help
by Foster.Patch＠accuweather.com 31 Jul '16

31 Jul '16

Hello, I have quite a bit of experience how xymon works in Windows, and recently was given assignments to do some monitoring in Linux. (RHEL 6) Below is my script. It runs with no errors, but my Hobbit page is never propagated with the new monitor. I have also gone to /etc/clientlaunch.cfg and put in the necessary lines to run this script. I am at a loss as to what is wrong, and why it will not propagate. Any help? (XYMSRV has an actual IP Address in it) #!/bin/sh . /etc/default/xymon-client export XYMSRV="xxx.xx.xxx.xx" export BBHOME="/usr/lib/xymon/client" export OUTSIDENAME="$CLIENTHOSTNAME" export BB="${BBHOME}/bin/xymon" export BBDISP=$XYMSRV export REALMACHINE="`echo $OUTSIDENAME | sed 's/\./,/g'`" export TARGETMACHINE="${REALMACHINE}" export TEST="CFENGINE" if [ ! "$TEST" ]; then exit fi if [ "${TARGETMACHINE}" == "${REALMACHINE}" ]; then LINE="status $REALMACHINE.$TEST green `date` <CENTER> This machine is not actively running this service in the cluster. </CENTER> "; # NOW USE THE BB COMMAND TO SEND THE DATA ACROSS #$BB $BBDISP "$LINE" # SEND IT TO BBDISPLAY $BB $BBDISP "$LINE" # SEND IT TO BBDISPLAY fi Thanks, Foster Patch Server Technician AccuWeather 385 Science Park Road, State College, PA 16803 P: 814.235.8650 E: Foster.Patch at accuweather.com<mailto:Foster.Patch at accuweather.com> E: networkoperations at accuweather.com<mailto:networkoperations at accuweather.com> http://www.AccuWeather.com<http://www.accuweather.com/>
