Chrome cookie deprecations (fix/workaround)
by EDSchminke＠Hormel.com 19 Jun '18

19 Jun '18

Hi All, I wanted to share my fix/workaround for the "Chrome cookie deprecation". Put the following code above the closing body tag in the $XYMONHOME/web/stdnormal_footer template file. -------------------------------------------------------------------------------- <script type="text/javascript"> var metas = document.getElementsByTagName('meta'); for (var i=0; i<metas.length; i++) { var type = metas[i].getAttribute("HTTP-EQUIV"); if (type == "Set-Cookie") { var prop = metas[i].getAttribute("CONTENT"); document.cookie = prop; } } </script> -------------------------------------------------------------------------------- Chrome has disabled, as a security measure, the ability to set cookies using HTML tags. Xymon (as of v4.3.27) relies on HTML cookies to allow a user to go from a particular page of monitored hosts to either the "Acknowledge alert" or "Enable/Disable" pages and, based on the origin, filter the hosts/alerts for that page. I've noticed it, as have a few others in the Xymon community. This should get us by until a permanent fix can be implemented in a release version. Erik D.

OpenVMS Client
by neilsimmonds1808＠gmail.com 12 Jun '18

12 Jun '18

Hi all, I can find some suggestion that there is an OpenVMS Big Brother client that is compatible with Xymon but can't find the actual client anywhere. Can anyone confirm if there is a client that will work with OpenVMS 8.4 1H1 and does anyone have a copy of it? Regards, Neil.

RRD graph not working for only one test
by rich＠corporationpop.co.uk 12 Jun '18

12 Jun '18

Hi all, weird one... Have been playing about with the following nginx monitor https://github.com/ZeWaren/xymon-nginx and I can't get the graphs to work at all. The test runs fine (as far as I can tell, i have modified the script to output the data for the graph and that all looks fine), it sends it's data etc and I can see the .rrd files created. However Xymon doesn't want to display them at all. I simply end up with alt text and the magnifying glass. Clicking the magnifying glass results in the "Cannot access RRD directory" error. I have performed an rrdtool dump on the offending graph and compared it with other .rrd files, doesn't look to be any issue. Permissions are all the same across all the data/rrd/host etc. Has anyone else had this issue or similar? Any ideas? I'm running Xymon 4.3.28 Cheers, Rich

Solved: EXTIME/TIME syntax
by losburn＠thepinnaclegroup.com 08 Jun '18

08 Jun '18

Thought I would mention solution here in case it saves some other folks a lot of head scratching. It turns out that the analysis.cfg file (and probably the alarm.cfg as well) seem to be whitespace-sensitive. That is to say, if your "LOAD" command doesn't begin at position 1 on the line, it may be interpreted as a combination condition with the line above. (of course, one may wish to combine several metrics for a single host, using the indented notation, but that is an intended whitespace) From: Xymon <xymon-bounces at xymon.com> On Behalf Of Lynn Osburn Sent: Thursday, June 07, 2018 9:12 AM To: xymon at xymon.com Subject: [Xymon] EXTIME/TIME syntax Attempting to prevent "false" cpu alarms during overnight processing, I have included a line in analysis.cfg thus: LOAD 4.0 6.0 HOST=blueteam EXTIME=W:2200:0400 However, alarms continue to be generated during the "excluded" hours. Has anyone else had any difficulty with either TIME or EXTIME entries? Thanks!

Setting thresholds in analysis.cfg
by chris.seip＠hpe.com 08 Jun '18

08 Jun '18

I could a hand getting the basics of analysis.cfg worked out, please. Here's mine: # egrep -v '^#' analysis.cfg HOST=%swnfs06.rose.rdlabs.hpecorp.net,%swnfs06 DISK /disk/data 50 55 DISK * 90 95 MEMSWAP 80 90 HOST=%swnfs07.rose.rdlabs.hpecorp.net,%swnfs07 DISK /disk/data 92 96 DISK * 90 95 HOST=%hpnsvr18.rose.rdlabs.hpecorp.net,%hpnsvr18 DISK /BACKUP 98 99 DISK * 90 95 DEFAULT # Ignore some usually uninteresting tmpfs mounts. DISK /dev IGNORE DISK /dev/shm IGNORE DISK /lib/init/rw IGNORE DISK /run IGNORE # These are the built-in defaults. You should only modify these # lines, not add new ones (no PROC, DISK, LOG ... lines). UP 1h LOAD 5.0 10.0 DISK * 90 95 INODE * 70 90 MEMPHYS 100 101 MEMSWAP 50 80 MEMACT 90 97 Three issues with this: 1. Swap consumption in the first host, swnfs06, has been steady at 74%, so I was trying to hush the alerts with the MEMSWAP line. This change hasn't had any effect; I am still getting a memory low yellow-warning for swap/page usage on swnfs06. 2. On the same swnfs06 host, its /disk/data partition is 56% full, so my "DISK..50 60" line was an attempt to trigger a yellow alert. I was testing my understanding of the analysis.cfg file, but the filesystems test remains green. 3. And my 96% full /BACKUP drive on hpnsvr18 is issuing a red alert for being over the panic level of 95%, where I was trying to set the panic level at 99%. After wrestling with the man page and many experiments, I'm tossing this to the group for help. Seems very basic, but it's just not working for me. What'm I missing? I tried switching to the "threshold hostname" format, like this: # egrep -v '^#' analysis.cfg | head -11 DISK /disk/data 50 55 HOST=%swnfs06.rose.rdlabs.hpecorp.net,%swnfs06 DISK * 90 95 HOST=%swnfs06.rose.rdlabs.hpecorp.net,%swnfs06 MEMSWAP 80 90 HOST=%swnfs06.rose.rdlabs.hpecorp.net,%swnfs06 DISK /disk/data 92 96 HOST=%swnfs07.rose.rdlabs.hpecorp.net,%swnfs07 DISK * 90 95 HOST=%swnfs07.rose.rdlabs.hpecorp.net,%swnfs07 DISK /BACKUP 98 99 HOST=%hpnsvr18.rose.rdlabs.hpecorp.net,%hpnsvr18 DISK * 90 95 HOST=%hpnsvr18.rose.rdlabs.hpecorp.net,%hpnsvr18 This produced no change in behavior. I am stopping and starting the Xymon server software and waiting for new html pages to generate after every change in the analysis.cfg. In my configuration report, I can see that every server configured for local memory tests has acquired the 80%/90% threshold setting, not just swnfs06. And my "DISK /disk/data 50 55" is having no effect at all on any host: The strings "50%" or "60%" appear nowhere in my configuration report. # egrep 'swnfs0[67]' hosts.cfg 16.93.247.204 swnfs06.rose.rdlabs.hpecorp.net # rpc=mount,nlockmgr,nfs,ypbind ssh 16.93.247.205 swnfs07.rose.rdlabs.hpecorp.net # NOCOLUMNS=files rpc=mount,nlockmgr,nfs,ypbind ssh 16.93.247.204 swnfs06.rose.rdlabs.hpecorp.net # xymoncmd xymond_client --dump-config DISK /disk/data 50% 55% 0 -1 red HOST=%swnfs06.rose.rdlabs.hpecorp.net,%swnfs06 (line: 351) DISK * 90% 95% 0 -1 red HOST=%swnfs06.rose.rdlabs.hpecorp.net,%swnfs06 (line: 352) MEMSWAP 80 90 HOST=%swnfs06.rose.rdlabs.hpecorp.net,%swnfs06 (line: 353) DISK /disk/data 92% 96% 0 -1 red HOST=%swnfs07.rose.rdlabs.hpecorp.net,%swnfs07 (line: 355) DISK * 90% 95% 0 -1 red HOST=%swnfs07.rose.rdlabs.hpecorp.net,%swnfs07 (line: 356) DISK /BACKUP 98% 99% 0 -1 red HOST=%hpnsvr18.rose.rdlabs.hpecorp.net,%hpnsvr18 (line: 360) DISK * 90% 95% 0 -1 red HOST=%hpnsvr18.rose.rdlabs.hpecorp.net,%hpnsvr18 (line: 361) DISK /dev IGNORE (line: 371) DISK /dev/shm IGNORE (line: 372) DISK /lib/init/rw IGNORE (line: 373) DISK /run IGNORE (line: 374) UP 3600 -1 (line: 377) LOAD 5.00 10.00 (line: 378) DISK * 90% 95% 0 -1 red (line: 379) INODE * 70% 90% 0 -1 red (line: 380) MEMREAL 100 101 (line: 381) MEMSWAP 50 80 (line: 382) MEMACT 90 97 (line: 383) Thanks for any insights you can provide. Feels like I'm making a wrong assumption about how analysis.cfg works. Best thing I can figure to do would be to switch to local configuration of my Xymon clients, but I'd rather manage custom thresholds centrally. - Chris

custom scripts for windows servers
by chrisp＠lightstoneauto.co.za 08 Jun '18

08 Jun '18

Good day I gave up with BBWin and ended installing xymonpsclient. It configured and reporting to the xymon server. How do I configure XymonPSClient to run my test script? Can you please send links with examples so I can see where I went wrong. Regards From: Robert Herron <robert.herron at gmail.com> Sent: Thursday, May 24, 2018 11:52 AM To: Chris Pretorius <chrisp at lightstoneauto.co.za> Cc: Lerch, Alfred <alfred_lerch at mentor.com>; Beck, Zak <zak.beck at accenture.com>; xymon at xymon.com Subject: Re: [Xymon] custom scripts for windows servers Test.groovy isn't an 8.3 filename but that doesn't seem to matter. If bbwin had a problem, I would expect something in the log about file not found -- similar to the logfetch message. Have you checked Task Manager to seee if there a orphanned groovy processes? The bbwin.log says it started groovy so maybe it's not fully initializing, can't open the groovy script, etc. I know you said you can manually run the script so maybe the user/context bbwin runs under doesn't have permissions to the groovy executable. Also, may create a simple "hello world" BAT or CMD file and add it as an external test. This should help prove bbwin can run externals and hopefully better narrow the problem.

This will depend on what tools you have installed on your servers. By default, Windows servers will definitely run VBScript (VBS) and most newer versions (Windows Server 2008 onwards, Windows 7 onwards) will run Powershell. There are a number of script samples in BBWin in the externals folder and for WinPSClient, the documentation is fairly complete in this area. Both BBWin and WinPSClient can return data from any script if that script writes a text file to the tmp folder (which is a subfolder of BBWin or WinPSClient). Below is a Powershell example of testing DNS lookup for google.com<http://google.com> – this is not necessarily the best way to test DNS, it is provided as a simple example of an external script. If this were saved as “google-dns.ps1”, and a SHA1 hash of the file generated, it can be used with the WinPSClient by adding a line like this to client-local.cfg – you do not need to replace the {script} with anything, the client will do that: external:everyscan:sync:http://<xymon server>/PS_Updates/google-dns.ps1|SHA1|<sha1 value>|powershell.exe|-executionpolicy remotesigned -noprofile -file "{script}" Cheers Zak param( [string] $TestName = 'googledns' ) $scriptdir = split-path -parent $MyInvocation.MyCommand.Definition $datadir = join-path $scriptdir '..\tmp' -Resolve $groupColour = 'green' try { $results = [System.Net.DNS]::GetHostAddresses('www.google.com<http://www.google.com>') } catch { $groupColour = 'red' $message = "Error performing DNS query: $_" } if ($groupColour -eq 'green') { $ips = $results | foreach { $_.IPAddressToString } $message = "Result of DNS query:`r`n" $message += ($ips -join "`r`n") } $timeFormatted = Get-Date -Format 'dd-MMM-yyyy HH:mm' $output = ` @" $($groupColour)+10m $TestName as at $timeFormatted (updated approx every 5 minutes) DNS query for www.google.com<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.google.com&d=DwMFAg…> $message <br><p>Information from $($Env:computername)</p> "@ $dataFile = Join-Path $datadir $TestName $output | Set-Content $datafile From: Xymon [mailto:xymon-bounces at xymon.com] On Behalf Of Chris Pretorius Sent: Friday, 4 May 2018 10:32 To: xymon at xymon.com<mailto:xymon at xymon.com> Subject: [External] [Xymon] custome scripts for windows servers Good day all Can someone please send links to example custom scripts for windows server.
