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

xymond not accepting connections
by David.Mills＠hhsc.state.tx.us 09 Dec '16

09 Dec '16

Hi, all! We have a rather murky situation. A colleague accidentally completely removed the Xymon (4.3.3 / Solaris) server home directory recently. It was restored from backups, but since then that server has not been completely functioning. ('Don't know if our symptoms are related to the home dir "zap" or what...) We periodically run the ghostlist.cgi app from cron and now these instances sometimes don't exit. When I run truss on them, I see they are almost continuously calling brk(): allocating anonymous memory for that instance's heap. It's gotten so bad that we've had this server's resources completely depleted and now have had to turn off the cron jobs The xymond daemon is no longer accepting connections, despite the fact that this server has been stable for years. The system was rebooted last night and seemed to be functioning throughout the night but stopped updating around 7:30 AM Confirmed xymond is no longer accepting connections via: 17:03:49 pwsu020:/var/log/xymon> telnet 127.0.0.1 1984 Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused 17:02:53 pwsu020:/var/log/xymon> ps -u hobbit -f UID PID PPID C STIME TTY TIME CMD hobbit 4132 4131 1 17:02:36 ? 0:26 xymond --pidfile=/var/log/xymon/xymond.pid --restart=/export/xymon/server/tmp/x hobbit 4288 4279 0 17:03:01 ? 0:01 /usr/bin/perl -w /usr/local/devmon/devmon hobbit 12895 12867 0 10:54:01 pts/5 0:00 -bash hobbit 4278 1908 0 17:03:00 ? 0:00 sh -c /usr/local/devmon/bin/restart.devmon> /dev/null 2>&1 hobbit 12491 5466 0 03:10:04 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 12490 5466 0 03:10:04 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 12487 5466 0 03:10:04 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 15958 5466 0 11:20:04 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 15612 5466 0 11:17:01 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 17158 5466 0 03:45:03 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 12488 5466 0 03:10:04 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 12489 5466 0 03:10:04 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 4290 4289 0 17:03:01 ? 0:01 /usr/bin/perl -w /usr/local/devmon/devmon hobbit 4257 4143 0 17:02:46 ? 0:00 /home/hobbit/xymon/client/bin/xymon 0.0.0.0 @ hobbit 15776 5466 0 11:18:51 ? 0:00 /usr/local/apache2/bin/httpd -k start hobbit 4148 4141 1 17:02:41 ? 0:21 /export/xymon/server/bin/xymonnet --ping --checkresponse --timeout=10 --dns-tim hobbit 4279 4278 0 17:03:01 ? 0:00 /bin/ksh /usr/local/devmon/bin/restart.devmon hobbit 4135 4131 0 17:02:41 ? 0:00 xymond_channel --channel=client --log=/var/log/xymon/clientdata.log xymond_clie hobbit 4140 4131 1 17:02:41 ? 0:21 xymonnet --report --ping --checkresponse --timeout=10 --dns-timeout=2 --dnslog= hobbit 4141 4131 0 17:02:41 ? 0:00 /bin/sh /export/xymon/server/ext/xymonnet-again.sh hobbit 4137 4131 0 17:02:41 ? 0:00 xymond_channel --channel=data --log=/var/log/xymon/rrd-data.log xymond_rrd --rr hobbit 4144 4131 0 17:02:41 ? 0:00 xymond_channel --channel=data --log=/var/log/xymon/data.log xymond_filestore -- hobbit 4131 1 0 17:02:36 ? 0:00 /export/xymon-4.3.3/server/bin/xymonlaunch --config=/export/xymon-4.3.3/server/ hobbit 4136 4131 0 17:02:41 ? 0:00 xymond_channel --channel=status --log=/var/log/xymon/rrd-status.log xymond_rrd hobbit 4133 4131 0 17:02:41 ? 0:00 xymond_channel --channel=stachg --log=/var/log/xymon/history.log xymond_history hobbit 12912 12885 0 10:54:09 pts/7 0:00 -bash hobbit 4143 4131 0 17:02:41 ? 0:00 /bin/sh /export/xymon-4.3.3/client/bin/xymonclient.sh hobbit 4289 4288 0 17:03:01 ? 0:00 /usr/bin/perl -w /usr/local/devmon/devmon hobbit 4139 4131 1 17:02:41 ? 0:21 xymongen --recentgifs --subpagecolumns=2 --ignorecolumns=files --tooltips=never hobbit 4134 4131 0 17:02:41 ? 0:00 xymond_channel --channel=page --log=/var/log/xymon/alert.log xymond_alert --che hobbit 4138 4131 0 17:02:41 ? 0:00 xymond_channel --channel=clichg --log=/var/log/xymon/hostdata.log xymond_hostda The only other clue I've been able to find is this note in the xymonlaunch.log file: 15:29:24 pwsu020:/var/log/xymon> tail -50f xymonlaunch.log ... 2016-11-17 13:54:36 xymonlaunch starting 2016-11-17 13:54:36 Loading tasklist configuration from /export/xymon-4.3.3/server/etc/tasks.cfg 2016-11-17 13:54:36 Loading hostnames 2016-11-17 13:54:41 xgetenv: Cannot find value for variable HOME 2016-11-17 13:57:44 xgetenv: Cannot find value for variable HOME 2016-11-17 14:00:46 xgetenv: Cannot find value for variable HOME Yet, when I tried this, as well as grep'ing through xymonlaunch "truss" output for HOME, I see valid home directory values: 13:58:35 pwsu020:~> echo 'echo HOME=$HOME XYMSRV=$XYMSRV XYMSERVERS=$XYMSERVERS XYMONDPORT=$XYMONDPORT' | /home/hobbit/xymon/client/bin/xymoncmd 2016-11-17 13:58:38 Using default environment file /export/xymon-4.3.3/client/etc/xymonclient.cfg HOME=/home/hobbit XYMSRV=0.0.0.0 XYMSERVERS=10.235.57.11 10.235.157.56 XYMONDPORT=1984 Help! david ~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~ David Mills Systems Administrator Northrop Grumman (512) 595-1238 (mobile)

client-local.cfg pattern matching
by EDSchminke＠Hormel.com 30 Nov '16

30 Nov '16

I think there is a problem with how xymon processes the client-local.cfg file when it comes to pattern matching. I have the following in my client-local.cfg: [host=%(elm|oak|oracle[0-9][dp])] Next time this file is checked, this shows up in the xymond.log: 2016-11-30 11:06:50.100740 pcre compile '(elm|oak|oracle[0-9' failed (offset 19): missing terminating ] for character class 2016-11-30 11:06:50.100829 Invalid host pattern in client-local.cfg: (elm| oak|oracle[0-9 It seems like whatever engine processes the client-local.cfg is doing a lazy pattern matching. Rather than taking everything up to the LAST closing bracket, it grabs up to the FIRST closing bracket. However this is designed to work, grabbing up to the first closing bracket seriously breaks PCRE matching. I think a change to this process is in order so that it grabs the LAST closing bracket. Especially, if a % is present, indicating the following is PCRE pattern. Thanks, Erik D.

telnet test leaving port hung.
by KK1051＠att.com 29 Nov '16

29 Nov '16

Xymon folks, I am running Xymon 4.3.10 and I am seeing an issue with the telnet test going to a Cisco term server (router with async cards to serial device). Randomly the term server will hang and show a refuse connection. We the term server is checked the hung session came from the Xymon server. When I check the Xymon server netstat I do not show a connection to the term server. I get the term server port cleared and we are ok again. Anyone see this behavior? -Kevin
