NetXMS Support Forum

I think I have a major misunderstanding of how netxms works.

My netxms server is Windows 2003/HMail. 
My netxms agents are running on Linux Ubuntu servers.
I use only netxms agents and no other collection method.

Today I was comparing the load and the number of apache2 processes running.

"w" was reporting entirely different load numbers than what netxms was reporting.
The number of apache2 processes actually running was entirely different than what netxms was reporting.

Here is where I think I am going wrong.

I had assumed if I am checking the

1) load average every minute, netxms agent will report the actual load average
2) or number of apache2 processes, netxms agent will report the actual number of apache2 processes running at that time.


Why I think what the linux os/system and netxms differ is because I think...
netxms is reporting the AVERAGE load over that time, and the AVERAGE NUMBER of APACHE2 processes over that time.

This is the only reason I can think of why the linux/os/system would be so different than the netxms values.

Another reason could be I am using delta values, but since I do not know how to setup or use delta values I doubt that is it.

I highly doubt netxms is reporting bad data, it is extremely likely I have not setup mty netxms collection/DCI or some other setting properly.

Please advise+TIA!

NetInterface.BytesIn and NetInterface.Bytesout out is an unsigned integer. 

With busy sites, should not this be an unsigned 64-bit ?

I see my network traffic graphs with a zig-zag pattern. From zero to 2147 MB and back to zero again, over and over.

In NETXMS, is there a summary/totals of network traffic collected so far ?

What parameter name should I be using?

Should I collect every 10 minutes with a retention of 365 days sound reasonable?


I need to view the summary of network traffic on the interface.(eth0)

I have been collecting network traffic on the interfaces.

I have been using NetInterface.Bytes.In+NetInterface.Bytes.out.
This gives me bytes per second on the interface.

I can export the network traffic data, but I really do not want to manually compile millions of data samples
to get a number that I can see just by looking at my overall network graphs.

I told my manager this, but I was told I need a hard number. (not an estimate of the average from a graph)

I did enable Network.Interface.Total, however since I only enabled+applied that today, that cannot help me.

ifconfig cannot help because instance are rebooted on occasion and the RX/TX counter resets to zero when the server is rebooted.

If you use Netxms and are viewing graphs, be sure to get some large multi monitor displays and extend the graphs onto multiple displays.
They have to crunch a lot of data into those graphs, but using large multiple monitors makes the data so much more readable.

I have NetXMS monitoring a group of servers I called Group A.
Now I want to add more groups, like Group B, Group C etc.

I need different emails/thresholds/notifications for each Group.

I cannot have Group A emails/thresholds going anywhere but to Group A email accounts.
Group B emails/thresholds to Group B email accounts and so on.

When I setup Group A, I used the default settings.
If I add Group B, I get Group B emails/thresholds going to Group A. Not good.

I think the only way to do this is reconfigure everything.

Template Groups
Alerts
Actions  (email accounts)
Event Processing

The part that I am having problems is, is Event Processing.
I do not know how to configure that to support multiple groups.

I am almost sure this can be done, just not sure how.
If you can assist me, I TIA!

I am only qualified to write that review in that I am a NetXMS newbie

I have 40 nodes in Template group >TMIS
I want to create a threshold for 10 of those nodes, not all 40.

Do I apply the threshold for all 40 nodes, and delete the theshold for the other 30?

Or can I apply the threshold for only those 10 nodes?

I would like to compare the CPU utilization of 8 different hosts.
Is there a way to do this?

I thought about combining the cpu graphs of the 8 hosts on a single graph.
Not sure if that is possible, or if there is a better way.

TIA

I am running NetXMS on a windows 7 that has VMWARE Workstation installed.

The 2 LANs I want to monitor are 172.16.1.0 (25 hosts) and 10.0.0.0 (25 hosts)

Because of VMWARE Workstation, I get 192.168.0.0 and 192.168.73.0 and 192.168.122.0
I delete these 3 192 subnets, but they keep coming back.

How do I configure NetXMS to monitor only 172.16.1.0 and 10.0.0.0 ?

TIA!

SYS_THRESHOLD_REACHED email is sent+passes all the parameters to the email fine.

Email subject = RAND1 System.CPU.LoadAvg=9.700000 threshold=1
Email body    =           System.CPU.LoadAvg RAND1 1 9.700000 0x00000189  1


When the threshold goes under 1, the
SYS_THRESHOLD_REARMED email is sent, but does not pass parameters

Email subject = RAND1 System.CPU.LoadAvg= threshold=0x00000189
Email body    = RAND1 System.CPU.LoadAvg= threshold=0x00000189

I got it figured out

Thresholds and email notifications are working.
I need to pass parameters in the email.

Here is my email notification about cpu load threshold higher than 2.
I tried passing variables but it is not the right way to do this?
What is the right way? If I am monitoring 100 boxes. I need to know what box it is

% 1 % 2 % 3 %4 %5 %6 %7 Average CPU is not yet passing parameters in email System.CPU.LoadAvg 0x000000F0 1 threshold is 2 currently 5.930000

Hello,

I am trying to get email notification working now. NETXMS Server is on Windows 7.

I was told by Victor to use an SMTP mail server that does not use SMTP authentication, or one that has SMTP authentication disabled.

To keep it simple as possible, I would like to use a local windows SMTP server on the same box as NetXMS server.

Is there a small Windows SMTP server that will do this?

TIA
Teddy

I did my network discovery first, so netxms-agents obviously are not found.

I am installing netxms-agent on 60 boxes one at a time.

However to get the netxms-agent detected, I have to delete the node and add it manually again.

Is there a better way of doing this?

Teddy

Thanks Victor,

You have build an amazing network monitor.
Thanks for having the patience in dealing with us newbies.

I do have Cacti up and running,
but if I can get NetXMS running with agents, I believe it will be a far better network monitor than Cacti.
I think an agent is a better solution than using only SNMP.

I dont know if you have ever tangled with Cacti, but it has issues with polling+RRA/RRD graphs.
