leaking memory, alerts.cfg problems

Oh, it’s xymond_alert not xymon_alert.

Xymoncmd couldn’t find xymon_alert. So it’s not in your path, you need to give the full path. I assume xymon doesn't stop sending alerts after a timeout period, right? We chose to use the SSH service since it doesn't affect our environment. We can add a fake hostname/ip as well. I fear may have something misconfigured since alerts won't go through at all. No. xymon sends alerts by what you define for it to send. There are no alerts by default. -Tres

extract one disk graph

On the trends & disk page I have all the disk ( mount point ) graphs. I have written another test and on that test page I would like to also display just one mount point's graph. I am hoping that since the data is already there, it is easy. How to do ? Where to start? Thanks bakkies

ACKCODE on recovery alert
by andrew＠eiknet.com 10 Sep '14

10 Sep '14

Hey - Question on ACKCODE - it appears this purposefully changes to 0 on recovery message. I was curious if there is a way to include the original alerts code on recovery messages? My use case it that I'm using a script to open a pagerduty.com incident using their API directly and using the xymon ACKCODE as the incident_key. If I have the same ACKCODE given with the recovery message I can resolve pagerduty.com incident when I get recovery from xymon. Thanks, Andrew

BBwin.cfg NAS drive syntax?
by kspringer＠innovateteam.com 10 Sep '14

10 Sep '14

I've got BBwin running on a bunch of machine and I'd like to monitor NAS drives that they connect to as well as the local disks. I add the mapped drive letter and the website goes red because it says it can't see that disk. I've tried the \\Name and also the \\IP but that doesn't seem to work. Anyone know the syntax that I need to add into the config file for it to work right? Signature - Kris Thank you. ------------------------------------------------ Kris Springer

leaking memory, alerts.cfg problems
by tres.finocchiaro＠gmail.com 10 Sep '14

10 Sep '14

Our organization is one of I'd assume many that are evaluating our options now that Dell no longer supports BigBrother. We had a fairly smooth transition to Xymon (we compiled form source on Ubuntu 14.04.1 LTS x86-64). The problem that we're having is that we can't find a sane way to remove a service check from our switches/routers, specifically TELNET. We removed the column from displaying on our webpage, but we were still receiving alerts on it. We've made customization to our alerts, but now no matter what we try, we can't get alerts to fire and sometimes see messages like: someuser at somehost:~$ sudo vi /etc/xymon/alerts.cfg > [sudo] password for someuser: > no talloc stackframe at ../source3/param/loadparm.c:4864, leaking memory I've scoured the internet to no avail. Any insight? If we can get the product running reliably we're sure to use it for years to come. :) -Tres - Tres.Finocchiaro at gmail.com

FreeBSD hobbit client has wrong path to log file
by kspringer＠innovateteam.com 09 Sep '14

09 Sep '14

I've got a hobbit client that I installed from a FreeBSD Package running on a pfSense firewall. It's working fine other than it trying to read /var/log/messages instead of /var/log/system.log. I can't seem to figure out how to define the log file. In the client /xymon/client/etc/hobbitclient.cfg I've set the CONFIGCLASS definition to "darwin" which is the only ostype that has the system.log type file (listed on the server in /xymon/server/etc/client-local.cfg). I restart the hobbit service on the client and wait a bit. The web page on my server says it's looking in /var/log/messages but it finds no entries (because duh, there isn't a file with that name). Where do I define the log file path in the client configs? Or can I define it in the server's hosts.cfg file?

Bug report: Powershell client doesn't use configured client name
by glauber.ribeiro＠experian.com 09 Sep '14

09 Sep '14

The Powershell client looks up the client name to send to xymon from [System.Net.NetworkInformation.IPGlobalProperties]::GetIPGlobalProperties() instead of using what's configured in the registry. I believe the problem is here (line 98 of xymonclient.ps1): if ((get-variable -erroraction SilentlyContinue "clientname") -eq $null -or $script:clientname -eq "") { $ipProperties = [System.Net.NetworkInformation.IPGlobalProperties]::GetIPGlobalProperties() $script:clientname = $ipProperties.HostName if ($script:XymonSettings.clientfqdn -and ($ipProperties.DomainName -ne $null)) { $script:clientname += "." + $ipProperties.DomainName } if ($script:XymonSettings.clientlower) { $script:clientname = $clientname.ToLower() } } The problem is the if statement above interrogates $script:clientname, instead of $script.Xymonsettings.clientname. g --- Glauber Ribeiro Experian Automotive, Schaumburg IL Infrastructure and Information Security e: glauber.ribeiro at experian.com p: 224-698-3108 f: 224-698-5032

vmstat @ AIX
by stef.coene＠docum.org 09 Sep '14

09 Sep '14

Hi, I just noticed that "vmstat 300 2" for AIX interpretes the vmstat command different then Linux: linux: output - sleep 300 - output AIX: sleep 300 - output - sleep 300 - output So for AIX, xymonclient-aix.sh should execute "vmstat 300 1" Otherwise, the vmstat is running for 600 seconds. Stef

Bug Report - Powershell client - overflow with disk size for large disks
by glauber.ribeiro＠experian.com 08 Sep '14

08 Sep '14

I sent this out a few days ago, but the list server seems to have been down. Retrying. Xymonclient.ps1, lines 346-347 has: [uint32]$diskusedKB = ([uint32]($d.Size/1KB)) - ([uint32]($d.FreeSpace/1KB)) # PS ver 1 doesnt support subtraction uint64's [uint32]$disksizeKB = [uint32]($d.size/1KB) Which is fine, until you have a disk that is large enough. When that happens, there is truncation. In the example below: 1K-blocks is correct Used is wrong - should be 2220117608 instead of 68526964 Avail is correct Capacity is wrong - should be 4% instead of 27% Summary is correct Example: [disk] Filesystem 1K-blocks Used Avail Capacity Mounted Summary(Total\Avail GB) ... F 2306837260 68526964 87800516 27% /FIXED/F 2199.97\83.73 I'm actually having some trouble figuring out where the overflow happens. I think Powershell must be using signed integers in some of the calculations. Maybe it's because of the 1KB constant. PS> 1KB | get-member TypeName: System.Int32 My fix was simply to remove all the [uint32] casts on those 2 lines. I'm running PS v2 PS> $PSVersionTable Name Value ---- ----- CLRVersion 2.0.50727.5466 BuildVersion 6.1.7601.17514 PSVersion 2.0 WSManStackVersion 2.0 PSCompatibleVersions {1.0, 2.0} SerializationVersion 1.1.0.1 PSRemotingProtocolVersion 2.1 If there is a pressing need to keep v1 compatibility, there may be a way to refactor the math so it works with uint32 (maybe casting the 1KBs), but I have a feeling that v2 compatibility is good enough.
