secondary question... what triggers the smtp check? Ive had instances where the test goes red, and then just a few seconds later back to green.? So this isnt a standard "every 5 minutes" clearly ? ... Wed Sep 29 08:44:39 2021 green 0:02:13 Wed Sep 29 08:44:15 2021 red 0:00:24 Wed Sep 29 07:44:36 2021 green 0:59:39 ... anybody know? cheers ian

Oh, by the way, the latest Xymon uses "ehlo xymonnet\r\nquit\r\n" as the send string (with the same expect string). I doubt that would make a difference. But you might be running a buggy xymonnet.

Could some other machine have been brought up using the same IP? Or "Oscar" have more than one IP associated with it? -----Original Message----- From: Xymon [mailto:xymon-bounces at xymon.com] On Behalf Of Ian Diddams via Xymon Sent: Tuesday, September 28, 2021 9:52 AM To: xymon <xymon at xymon.com> Subject: [Xymon] SMTP checks _______________________________________________ Xymon mailing list Xymon at xymon.com http://lists.xymon.com/mailman/listinfo/xymon

xymon server 4.3.28, centos 7.9 mail server centos 6 (about to be replaced anyway) I'm in a bit of a quandary... we have an smtp check of a server ("oscar"). Literally for "years" (3+) the xymon in house smtp check has been more than happy. Then since Sept 11th [1] its been flipping constantly beyween green and happy to red eg Service listening but unavailable (connect timeout) Seconds: 0.001842000 But if I run a telnet test from the xymon server itself it always connects immediately, and responds instantaneously. eg $ telnet oscar 25 Trying <redacted>...Connected to oscar. Escape character is '^]'. 220 a.b.co.uk ESMTP Postfix mail 501 5.5.4 Syntax: MAIL FROM:<address> quit 221 2.0.0 Bye Connection closed by foreign host. $ All xymon logs show are emails being sent because of the alerts, ad falling statuses that are a result of the constant flipping from red to green. maillog has nothing untoward, ditto messages. Anyone any ideas what on earth is suddenly occurring that may explain this recent timeout issue?? any expereince of similar? didds [1] no changes made around that time etc.? Networks confirm nothing shoing in their logs etc.

possible to add columns to some subpages instead of globally to all?
by tachyon178＠protonmail.com 23 Sep '21

23 Sep '21

Hi, Is it possible assign its own number of columns in subpages, don't want to set in from xymonserver.cfg, want it customized for specific subpages instead of globally. At the end I would something like this, for example: Subpages Hosted Locally ------------------------------------ West Zone East Zone California New York Washington New Jersey Would like West Zone and East Zone to be a sub-title of sorts. West Zone and East Zone should just be a header of the table, states names should bring you to the hosts assigned. Thanks! Sent with [ProtonMail](https://protonmail.com/) Secure Email.

help/suggestion required since upgrade to 4.3.30
by rajeshinside＠gmail.com 21 Sep '21

21 Sep '21

Hi David, Hope you are well! Do you mind sharing the steps/procedures that was taken to upgrade xymon-client from 4.3.28 to 4.3.30 I'm relatively very new to xymon and can't find the steps. " Hi I have recently upgraded from 4.3.28 to 4.3.30 Everything seems to have installed ok, without any issues. The problem I think I have is the http(s) test for the actual xymon server, on version 4.3.28 the test worked ok and I got a green result Since upgrading the test now shows red, it actually sayshttps://vmsg-xymon1.corp.renfrewshire.gov.uk/ - Bad Request HTTP/1.1 400 Bad Request Date: Tue, 11 May 2021 09:59:47 GMT Server: Apache/2.4.6 (CentOS) OpenSSL/1.0.2k-fips mod_wsgi/3.4 Python/2.7.5 mod_perl/2.0.11 Perl/v5.16.3 Content-Length: 362 Connection: close Content-Type: text/html; charset=iso-8859-1 Seconds: 0.002957000 On my other xymon server which is still the older version, same test is ok. The other thing I noticed is that on the xymonnet test on each server, on version 4.3.28 it shows SSL library but on 4.3.30 it does not. Any ideas or suggestions are most welcome David " -- Regards, Rajeshkumar Mani

Disk tests for multihomed devices fail or don't match
by tp6891＠att.com 10 Sep '21

10 Sep '21

Hi I am running an older xymon 4.3.10 and noticed the Disk tests in analysis.cfg are not working for hosts with multihomed network interfaces. It seems to work fine on hosts with 1 IP address. Plus I get "WARNING: Flapping status" because different IP's report back. Example: analysis.cfg HOST=serverxyz DISK "%^/cdrom/.* IGNORE Or DISK /cdrom/sol_10_811_sparc IGNORE Or DISK /cdrom/sol_10_811_sparc 101 102 Or DEFAULT DISK %^/cdrom/.* IGNORE hosts.cfg x.x.x.x serverxyz # CLIENT:serverxyz !telnet multihomed Thanks Tim

exclude devices from temp check?
by zechner＠vrvis.at 02 Sep '21

02 Sep '21

Hi, I've been using the "temp" check from xymon's plugins (on Debian) and wanted to ask if it was possible to excluce certain devices from the check. We have "problems" with an USB stick, which is permanently plugged into one of our machines and which does not have any temperature sensors or readings, but sometimes xymon decides it now has somewhere around 200 ?C, which is of course not possible. Other checks like "libs" have dedicated yaml files which allow customisation, is there any such option for the "temp" check as well? Thanks in advance! Best regards Christoph Zechner
