[PATCH] Fix debian init script problem for Container based virtualization
by ml＠jjim.de 07 Apr '16

07 Apr '16

Hi, I just now submitted a debian bug for this because I hope that it gets fixed in Debian stable, but I also wanted to put this on the list (the bug does not have an ID yet, I will put it in the thread). I post this here, because there is an init-script in the xymon-sources debian/ directory (debian/xymon-client.init). I discovered then when having a debian host where (in my case) LXC virtual machines run, it is impossible to start the xymon-client there, when another xymon-client is already running in one of the containers. This seems to be, because the invocation of start-stop-daemon does only check the process name. The problem can be resolved by adding the --pidfile argument to the start-stop-daemon invocations so that start-stop-daemon does not only check the process name but also the PID. During a quick test, the attached patch was fixing the problem. Kind Regards, /jbn -- Joel Brunenberg - Troisdorf PGP: 0xAD25981C

status+ in custom tests
by neilsimmonds1808＠gmail.com 07 Apr '16

07 Apr '16

Hi all, Is there any way on the Xymon server to check if any custom tests have a validity timeout that is not default because they have a parameter on the status command setting a custom validity. I'd prefer to do it from the server as it would be very time consuming to have to log onto every client to check it. I know we have some that aren't using the default 30 minutes but I really need to identify them due to other people writing custom scripts and apparently not understanding what status+**** does. Thanks, Neil.

DNS test interaction with 0.0.0.0
by john.thurston＠alaska.gov 06 Apr '16

06 Apr '16

I have a couple of name servers which are not pingable. I have them in my hosts.cfg as follows: > 10.10.10.10 ns1-int.foo.com # noconn dns=ns1.foo.com > 0.0.0.0 ns2-int.foo.com # noconn dns=ns2.foo.com The first returns a green dns test result. The second returns a red "Service dns on ns2-int.foo.com is not OK : Service unavailable." I can't figure out why. I don't want to embed ip addresses in my hosts.cfg, and I can't think why I should need to. There is nothing telling when I run the test interactively with: xymoncmd xymonnet --no-update --debug ns1-int.foo.com nor for ns2-int.foo.com When I snoop the interface while doing the above tests, the differences are significant: For ns1-int, I see xymon lookup ns1-int on the normal name server. Then I also see it request ns1.foo.com from ns1-int.foo.com and get the correct response. I'm not sure why the reverse lookup is there. > xymona -> d.foo.com DNS C ns1-int.foo.com. Internet Addr ? > d.foo.com -> xymona DNS R ns1-int.foo.com. Internet Addr 10.10.10.10 > xymona -> ns1-int.foo.com DNS C ns1.foo.com. Internet Addr ? > ns1-int.foo.com -> xymona DNS R ns1.foo.com. Internet Addr 192.168.123.1 > xymona -> d.foo.com DNS C 10.10.10.10.in-addr.arpa. Internet PTR ? > d.foo.com -> xymona DNS R 10.10.10.10.in-addr.arpa. Internet PTR ns1-int.foo.com. For ns2-int, however, the result is much simpler. I see xymon lookup ns2-int on the normal name server. . . . and then nothing. > xymona -> d.foo.com DNS C ns2-int.foo.com. Internet Addr ? > d.foo.com -> xymona DNS R ns2-int.foo.com. Internet Addr 10.20.20.20 When I change the line in hosts.cfg for ns2-int from 0.0.0.0 to an ip address, it works fine. What is going on here? Why isn't the DNS test using the address it has obviously retrieved from DNS? -- Do things because you should, not just because you can.

adding a SVCS column for non-Windows clients?
by rlhamil2＠gmail.com 06 Apr '16

06 Apr '16

Solaris 10 and later, and Mac OS X have a more or less similar* concept to Windows services: processes that are kept running by svc.startd (Solaris) or launchd (OS X). It seems to me not unreasonable for them to report those in the same column, and to be able to use at least some of the same syntax for the SVC line (status={started|stopped} only, since checking for the equivalent of startup= would be at best unduly tedious; i.e. neither svcs -a (Solaris) nor launchctl list (OS X) actually report whether the setting of a "service" is such that they'll be enabled at next reboot). Here's the thing: I'm not clear what actually evaluates the SVC expression against the client data; does that happen on the server, or on the client? In other words, what magic do I need to know to write a client-side script that will not only report the data, but do whatever its part of the job is in terms of either formatting it so the server can evaluate it, or so the client can obtain the configuration info from the server, as applicable? * I realize Windows services imply a bit more than just processes managed by the OS; but I don't think those differences are relevant to what I'd like to do.

Depends tag working configuration
by rower.master＠gmail.com 05 Apr '16

Hi Scot, Thanks for your help. I´ve used your example and the dependency worked using the http test. So then, I´ve changed the depends tag configuration to use the conn test and this didn't work. First test (worked as expected!): - Stopping apache on "6030" the result was a clear status on 6030/http as 5030/http was up. 0.0.0.0 6030 # http://paq depends=(http:5030/http) noconn 0.0.0.0 5030 # http://fara noconn Second test (connectivity configuration on depends): This test didn´t work. - I´ve changed the IP from 6030 to a non pingable IP and let an available/online IP on "5030" and the depends tag didn´t work. 10.0.0.139 6030 # http://paq depends=(conn:5030/conn) testip 10.0.0.137 5030 # http://fara testip Do you have a dependency configuration based on connectivity test working on your system?

The '/''s in the URL, however, may need to be rewritten as commas to match. I had considered adding in a patch to allow HTTP URL's to be substituted with a status column name for RRD purposes, when one is supplied (using the =col syntax), which might help in this case as well. The original requirement for that one was a URL with a CGI query that changed from time to time but whose history we'd wanted to keep. HTH, -jc

DS - RRD based status override
by apocalysque＠yahoo.com 04 Apr '16

04 Apr '16

I've successfully set up monitoring for, and the ability to log in to a website on my xymon, and the content and https checks both work, but I'd also like the content column to be affected by the response time. The man page for analysis.cfg says I can use a DS tag to do so, but it also says that there's a colon in the syntax... DS column filename:dataset rules COLOR=colorname TEXT=explanation The problem I'm having is that the rrd filename (which was created automatically by xymon) has a colon in it. How would I handle this while setting up my analysis.cfg file? Do I escape that colon somehow? Double/single quote the filename? Does anyone here know or do I have to dig into the source? I was unable to find an answer in the man pages. TIA Jason T. Brockdorf Systems Analyst Identity and Access Management Texas Health and Human Services 512-438-2903

IPv6 support
by rodolfo＠pilas.guru 01 Apr '16

01 Apr '16

Today I have set couple of my servers to be monitoring throught IPv6 stack, and it do not work :( (I have xymon 4.3.17) I have readed hosts.cfg documentation and also this thread from 2011: http://lists.xymon.com/pipermail/xymon/2011-August/thread.html#32213 Do you know the status of IPv6 suppoort on Xymon Server? Do I need to setup/configure something else? Thank you. -- Rodolfo Pilas @pilasguru https://pilas.guru gpg: 2048R/23B5BE7B FCE6 6FC5 849D A0F6 E30D D1FC A33C 4E64 23B5 BE7B
