Hi everyone, I've looked all over the place and I just cannot figure out why I'm getting this error: Symbolic link not allowed or link target not accessible: /home/xymon/cgi-bin/svcstatus.sh, referer: http://home.com/xymon/allservers/allservers.html Here is part of what my xymon-apache.conf looks like: Alias /xymon "/home/xymon/server/www" <Directory "/home/xymon/server/www"> Options Indexes FollowSymLinks Includes MultiViews Order allow,deny Allow from all </Directory> ScriptAlias /xymon-cgi/ "/home/xymon/cgi-bin/" <Directory "/home/xymon/cgi-bin"> AllowOverride None Options ExecCGI Includes Order allow,deny Allow from all </Directory> ScriptAlias /xymon-seccgi/ "/home/xymon/cgi-secure/" <Directory "/home/xymon/cgi-secure"> AllowOverride None Options ExecCGI Includes Order allow,deny Allow from all Any help/handouts/hints would be very helpful!

Hi, is there an Xymon addon to monitor e-mail traffic on Sendmail servers? Would like to see graphs of sent and rejected e-mails on a daily basis if possible. Regards, Nick Pettefar

Macro confusion
by scoile＠mcclatchyinteractive.com 06 Mar '15

Given two different, but trivial alerts.cfg files: --- file 1 --- $H=HOST=a,b SERVICE=conn $H --- file 2 --- $H=HOST=a,b $H SERVICE=conn --- The first file will match hosts a and b but not c; the second file will match nothing. Take "SERVICE=conn" out of file 2, it then properly matches a and b but not c. What gives? -- *Steve Coile*Senior Network and Systems Engineer, McClatchy Interactive <http://www.mcclatchyinteractive.com/> Office: 919-861-1247 | Mobile: 919-622-5369 | Fax: 919-861-1300

mixing red and yellow alerts in a --test check
by didds3＠yahoo.co.uk 06 Mar '15

06 Mar '15

is there a way to mix a --test page check between alert colours? I can use eg server/bin/xymond_alert --test TESTBOX http --color=yellow --duration=120 --time=1425224089 server/bin/xymond_alert --test TESTBOX http --color=red --duration=2 --time=1425224089 but I want to check a combination of the two - when the two hour yellow alert (set to not page) is followed by the tow minute red alert (which shoud not page for 30 minutes) The context of this is that we are being paged for the red alert which in itself has not reached the 30 minute duration configured and we belive its because the red iummediately follows the yellow and the COMBINED alert duration exceeds 30 minutes. the alerts.cfg entry is HOST=TESTBOX SERVICE=http TIME=w:0000:0759,w:1830:2359,06:0000:2359 COLOR=red MAIL check at xxx.co.uk DURATION>30m REPEAT=15 the --test paging check works as expected and correctly for color=red and testing with durations of 29 and 31 minutes The http check itself is an external script which has worked fine for years and years and years. it is purely this combination of yellow and red alerts that we suspect is the reason for our otherwise unexpected paging (unexpected throughout naivety I hasten to add :-) cheers ian

Regarding xymon alerts
by itlinkstonisha＠gmail.com 05 Mar '15

05 Mar '15

Hi, I have setup xymon server 4.3.10, here I have the issue with xymon alerts. When conn test for a xymon client fail, I get alerts for all the services monitored on the client, same when I reboot the client then the recovered alert I get for all the services. In such situation I just wants the alert for conn test not all the services. Please help me to avoid this flood of alerts. "Apologizing does not mean that you are wrong and the other one is right... It simply means that you value the relationship much more than your ego.."

Xymon PowerShell Windows client

Hi David First of all, thanks for providing us with a great starting point with the Powershell client. We've discussed this in-house and agree that the best long term solution would be to fix/extend the server code. Now, it's been a long time since I looked at any C code, but it looks to me (looking at commit 7594 in trunk) that do_ifstat.c needs the following addition: case OS_SCO_SV: if (pickdata(bol, ifstat_sco_sv_pcres[0], 0, &ifname, &rxstr, &txstr)) dmatch = 7; break; + case OS_WIN32_POWERSHELL: case OS_WIN32_BBWIN: if (pickdata(bol, ifstat_bbwin_pcres[0], 0, &ifname, &rxstr, &txstr)) dmatch = 7; break; Zak From: David Baldwin [mailto:david.baldwin at ausport.gov.au] Sent: 04 March 2015 23:50 To: Jeremy Laidman; Beck, Zak Subject: Re: [Xymon] Xymon PowerShell Windows client On 5/03/15 10:00 AM, Jeremy Laidman wrote: On 04/03/2015 7:49 PM, <zak.beck at accenture.com <mailto:zak.beck at accenture.com> > wrote: > Unfortunately, you can't fake the BBWin identifier for just one section – you have to change the client to report in as BBwin. It was changed so that we could experimentally use separate configuration options for BBWin clients and Powershell clients. Of course the best option is to extend the server to match the features of the client. It wouldn't take much (like one line) to add the powershell OS into the ifstat handler, running the same code as for bbwin. I took a look at the current code in trunk today - the powershell client (however that is detected) looks like it is treated the same as BBWin at present. Server-side extension in the C code is fine for those comfortable with that, but makes it difficult for those wanting to just try out the new client against an existing server. David.

Xymon PowerShell Windows client

Hi Zak, I want to be able to see the network traffic in/out on each NIC on my windows machines running the new PowerShell client, I have never really looked into how this worked in bbwin but if I look at a few example machines I see the following: 1. On a Linux machine I get Network Traffic and TCP/IP Statics graphs on the trends page a. Raw data contains [ifstat] and [netstat] information 2. On a windows machine running BBWin 0.13 I only get a TCP/IP Statics graph on the trends page a. [ifstat] is blank b. [netstat] contains data e.g [netstat] ipPacketsReceived=53513930 ipReceivedHeaderErrors=0 ipReceivedAddressErrors=355513 ipDatagramsForwarded=0 ipUnknownProtocolsReceived=2158 ipReceivedPacketsDiscarded=1266110 ipReceivedPacketsDelivered=52167159 ipOutputRequests=31961136 ipRoutingDiscards=0 ipDiscardedOutputPackets=5221 ipOutputPacketNoRoute=0 ipReassemblyRequired=730696 ipReassemblySuccessful=199056 ipReassemblyFailures=0 ipDatagramsSuccessfullyFragmented=0 ipDatagramsFailingFragmentation=0 ipFragmentsCreated=0 ipv6PacketsReceived=7895 ipv6ReceivedHeaderErrors=0 ipv6ReceivedAddressErrors=0 ipv6DatagramsForwarded=0 ipv6UnknownProtocolsReceived=0 ipv6ReceivedPacketsDiscarded=5199 ipv6ReceivedPacketsDelivered=7908 ipv6OutputRequests=2596918 ipv6RoutingDiscards=0 ipv6DiscardedOutputPackets=0 ipv6OutputPacketNoRoute=2 ipv6ReassemblyRequired=0 ipv6ReassemblySuccessful=0 ipv6ReassemblyFailures=0 ipv6DatagramsSuccessfullyFragmented=0 ipv6DatagramsFailingFragmentation=0 ipv6FragmentsCreated=0 3. On a windows machine running PowerShell client v1.98 I don't get any network related graphs however I seem to have data available: a. [ifstat] contains data e.g [ifstat] fe80::25a5:b99d:55cd:951f%12 2655878237 519887923 10.250.100.163 2655878237 519887923 a. [netstat] contains data e.g [netstat] PacketsReceived=3387463 ReceivedHeaderErrors=0 ReceivedAddressErrors=51034 DatagramsForwarded=0 UnknownProtocolsReceived=0 ReceivedPacketsDiscarded=146872 ReceivedPacketsDelivered=3219450 OutputRequests=950747 RoutingDiscards=0 DiscardedOutputPackets=102 OutputPacketNoRoute=0 ReassemblyRequired=83643 ReassemblySuccessful=27881 ReassemblyFailures=0 DatagramsSuccessfullyFragmented=0 DatagramsFailingFragmentation=0 FragmentsCreated=0 PacketsReceived=1266 ReceivedHeaderErrors=0 ReceivedAddressErrors=0 DatagramsForwarded=0 UnknownProtocolsReceived=0 ReceivedPacketsDiscarded=618 ReceivedPacketsDelivered=1264 OutputRequests=11680 RoutingDiscards=0 DiscardedOutputPackets=0 OutputPacketNoRoute=2 ReassemblyRequired=0 ReassemblySuccessful=0 ReassemblyFailures=0 DatagramsSuccessfullyFragmented=0 DatagramsFailingFragmentation=0 FragmentsCreated=0 The netstat data in the PowerShell client doesn't seem to have the ip / ipv6 infront of the values so they are listed twice in the example above. So I'm not sure what graphs should I be expecting to get under trends with the PowerShell client for network traffic? At the moment I'm guessing the ifstat data isn't in a format xymon will automatically graph and add to the trends page and the same for the netstat data possibly just because it has duplicate values for ipv4 and ipv6. Regards, Brandon From: Xymon [mailto:xymon-bounces at xymon.com] On Behalf Of zak.beck at accenture.com Sent: Friday, 13 February 2015 8:53 PM To: xymon-developer at lists.sourceforge.net; xymon at xymon.com Subject: [Xymon] Xymon Powershell Windows client Hi all, Today I have uploaded a new version of the Xymon Powershell client to SVN (in sandbox/WinPSClient). We (Accenture) are very pleased to be contributing these changes to the open source community. I've been working on this now for around 8 months on and off and hopefully the changes made will be of benefit to everyone! Whilst making changes, we have focussed mainly on making it work, improving reliability and most importantly improving performance. In most cases, on our 64 bit OS virtual machines, a data collection now takes around 5 seconds. On heavily loaded (CPU load or event log load) servers, the script is now considerably faster than originally. Key to this has been reducing the amount of WMI usage as this was a major culprit. We have also implemented some new features, largely based on our in-house requirements but hopefully useful to others: * Showing the process owner and command line in [procs]. This has been implemented using c# code, compiled at runtime. * Adding Active Directory replication test, Terminal Services sessions test * Ability to restart any stopped Windows service * Client self-update * Dirsize and dirtime checks (which were originally external scripts) Some things have changed slightly; for example, the local configuration which was registry-based is now XML-based (you can still use registry settings if you prefer). In the SVN repository I have also uploaded a Word document which describes how to install and the configuration options. I have uploaded all the revisions we have made to SVN so there is a history of development. Whilst we will endeavour to continue contributing changes and improvements in coming months, this is an open source project and as such we are not offering any formal support. If anyone wishes to bugfix, branch or whatever, please do so! Zak Beck Accenture
