and if i look at the commands.cfg file I do not see the command I entered for check_mem
looks like the gui thinks the command has been "uploaded" to the file but it actually hasnt.

An issue similar to this has been reported recently in the Customer Support Forum. We will take a closer look.
Thank you.

I have had similar issues. To determine if you are getting the same problem as me try this:
- Login to Core Configuration Manager (CCM)
On the right click Tools and then click Write Config Files
Click the Go button for Write monitoring data
Underneath it will display the results.
My problem was that all configs after
Write hostgroups.cfg failed to write. To fix it I did the following:
Access the Console of your Nagios XI server or use Putty to connect to it remotely
Type
chmod o+w /usr/local/nagios/etc/*.cfg and press
Enter
If you click the
Go button for
Write monitoring data it should now be successfull.
However if the problem still exists try the following:
Type
chown root:root /usr/local/nagios/etc/*.cfg and press
Enter
And click the
Go button for
Write monitoring data
Hopefully this fixes your problem and if it does can you please confirm which command (or both) fixed the problem.
Thanks
Troy

Just make sure all the form data you submit is correct. Sounds like you are just needing to enter a positive value into "check time period" for Service 'Memory Usage' on host 'sqltest.a4egroup.co.uk'. You may also have not correctly configured your new Check Command, missing forum fields can ruin your hole day.

Incorrect memory reported by Win 2008 R2 client

Hi, I started to look at Nagios XI by adding Windows Server 2008 R2 Std host running as vmware sphere 4 virtual machine with 8 Gb of memory, but Nagios XI (or nsclient++) reports all memory amounts (total and used) multiplied by 2 - eg 16 gb in total instead og 8 gb, used 8 gb insted of 4 gb.
I am running Nagios XI 2009R1.1H downloaded as virtual machine on vmware 4, nssclient++ 0.3.7 64 bit on Windows.
Any ideas? I am quite experienced Nagios 2x and 3.x, NagiosQL etc user, so I beleive it´s rather software bug than install/config...

Interesting... A couple possibilities that spring to mind:
Is the amount of memory available to your VM "burstable" in any way?
Could the pagefile be included in those figures, returning total virtual memory instead of just RAM?
Is the *used* memory amount *exactly* double? (That might help narrow things down at least.)
Also, could you clarify, is just Nagios XI a VM or are both XI and the Windows server in VMs?

This virtual machine has 8 GB (8192 MB) of virtual memory dedicated to it (it is enought of phisical memory in this vmware cluster)
Could the pagefile be included in those figures, returning total virtual memory instead of just RAM?
It possible, becouse page file is 8 GB at the moment
Is the *used* memory amount *exactly* double? (That might help narrow things down at least.)
I looked better on it - no, it´s not. There are 6692 MB (85%) in use as reported by Win Resource Manager but Nagios reports 7860.28 Mb (48%) for used memory
Also, could you clarify, is just Nagios XI a VM or are both XI and the Windows server in VMs?
Both machines are VMs inside one vmware Datacenter (but not inside the same cluster)

We were able to confirm that it is checking a combination of all virtual memory - physical plus pagefile. This is a limitation of the check_nt command used by default. If you would like to separate that out it is possible, but will require changing the check command to use check_nrpe instead. Additionally, you will need to modify the NSClient++ config file on the target machine to allow arguments in the NRPE section. You can modify the check command from within the Core Config Manager, and make it read something like this:
check_nrpe -H 192.168.5.9 -p 5666 -c CheckMEM -a MaxWarn=80% MaxCrit=90% ShowAll type=physical
The "type=physical" part will restrict it to just RAM. See
http://nsclient.org/nscp/wiki/CheckMem for more documentation on this check command.
