Sounds great

Thanks!

Hi!

It all comes down to the amount of DCI's you wish to poll and the polling intervals.

We are using the following CPU and RAM for around 800 nodes with, at the moment, about 25 - 30 DCI's per node,
1x Intel(R) Xeon(R) CPU W3520
12GB RAM

And we are not close to maximizing the resources.

Hope this helps!

Edit: We would probably be able to handle the current load with half the memory, but as you never know what the future hold, and as hardware is relative cheap, it is better to oversize, than to not be able to monitor what you need to

Hi!

I am wondering about the object tools from the alarm browser.
I wish to send data by right clicking on an alarm in the browser and select object tools and then for example "create ticket", to create a ticket in the ticket system.
The idea would be to invoke either an action or some command on the netxms server which then sends for example alarm text, time when the alarm was triggered and which user that created the ticket.

Is this doable? Can I send this data from the alarm browser?
Or is it purely an "object" tool?

The reason why I wish to do this instead of an automatic creation is that otherwise the ticket system will be filled with a lot of new tickets, which is not fun to handle.
We are still trimming the system and adding more nodes and alarms so I have not had time to fix situations to remove excessive alarms, yet

Thanks in advance!

Good morning!

Hm ok, not sure what the best way is, but there are some positive things that come out of having an extra instance that can be separated from the live environment.
I think that will be the way to go for me

Thanks!

Hi!

Sorry if this has already been covered in the forum, but I was unable to find it.

Is there any way to limit the view for specific users, or groups, to a DCI or alarms?
I am thinking about the same way to limit the view of an object.

I have nodes with a lot of different DCI's and a lot of different users accessing the same server.
The service desk group should see all the alarms, which they do today.
But then I have a few other users that should only be able to see some of the alarms, for example if application A is down that will create a critical alarm, I would only want them to see that alarm.
If application B goes down on the same node, I don't want them to see that alarm.

It is possible to do it with another Netxms server instance and just forward the necessary alarms for those nodes to the "new" instance, but, it would be great if it was possible to do it in the same server.

Sorry, it is 32 bits, it is apparently not R2, it has Service Pack 2 though!
From description:
"Windows SCHED 6.0.6002 Windows Server 2008 Build 6002 Service Pack 2 Intel IA-32"

Yes it is the 1.0.4 agent, 32-bits.

The server has also been restarted now, just to ensure that it is nothing trivial like that, but it displays the same errors, so I changed the user who runs the nxagent to the administrator, and now it works
Not optimal, but something is not as it should with the local system account

I think I will let some windows admin look at it.
Thanks for your help!

Just made sure and it is only my own specified parameters through "ExternalParameter" in the netxms agent configuration file that is now working, everything else seems to be running fine, which is a bit disturbing
When I try to run the parameter I have specified manually it works like a charm, but not through the agent.

If it were any problems running the parameter there should be another error in the event log, or am I wrong?

Edit: I found another error message as well, this time on NetXMS, "Unable to open buffer file" in the "last values" history for the node when I clicked on it through the alarm browser.

The variables are set, both TMP and TEMP (and the others), I also checked the user rights and they were set as they should I guess, everything checked on "allow" and nothing on "deny".
The hard drive is not full. I have tried to stop and start the agent again.

The strange thing is that it is only on this server.
Do you have any other ideas what could be wrong?
I could suggest a reboot of the server, but not sure if that would help?

Thanks again!

Dan

Hi,
Thanks!

I'll check the values of the environment variables and get back asap!

The agent is running under the local system account, it's just a default install, is there anything special to consider?

Best regards,
Dan

Hello!

I have a server running Windows 2008 R2.
I have installed the netxms agent, we are currently running version 1.0.4, and is able to connect, it is stated as "Active" under the nodes "Overview".

In the netxms configuration file I have created a number of external parameters which all runs as they should from the command line, but when I try to connect and run it through NetXMS I receive the following error message: "Cannot get parameter: Communication failure".

If I look in the event viewer on the windows machine I can see that there are a number of errors related to the agent containing this error message:
"Unable to create temporary file to hold process output: The system cannot find the path specified"

I have other windows servers running with the same configuration and they are running fine.
Where is it trying to create the temporary file?
Could it be a file system access problem?

Thanks for your help!

Seems like that was the problem, the difference between %5 when using it in a threshold and a rearm event.

Thank you very much for your help!

Best regards,
Dan

Hi!

I think it is me that configured it wrong, I used %5 on my rearm, instead of %3.
I will try this first just to ensure that it is not me.

If it does not work I will try to explain my configuration

Thank you for your answer!

Best regards,
Dan

I forgot to mention that I am using 1.0.4.

Hi!

I found this in the forum, which is a great way to differentiate events:

Hi!

I would suggest to change alarm key in your configuration for %m (message text) to DC_%i_%5 - that would create separate alarms for different nodes, even if they have same message text. But anyway, that is not important for sending e-mails. From information you have sent it is not clear why you getting e-mail only for 1 DCI - I should see configuration and values of all 4 DCIs. Also, was it your intention to send e-mails every minute as long as there are files matching filter?

But, when I use it in already existing events in my event processing policy, it is blank.
If I try to set it as a text message, the macro parameter is shown as a blank, i.e null or nothing.

I configure the DCI that uses these events from a template that distributes to my nodes.

When I create a new DCI on one of my nodes, not through a template, and then test it, the macro %5 shows output, which I think is the correct one.

Could there be a problem because I use a template?

Dan

I thought I could share the result.


sub main() {
  numImages = $1;
  if ($node->name ~= "^(.*)ru[rf]([0-9]{2})1") {
     plaza = $1;
     lane = int64($2);
  }
  mlc = plaza . "mlc010";
  mlcNode = FindNodeObject($node, mlc);
  dciName = "Total number of transactions in Lane " . lane;
  numTransactions = GetDCIValue(mlc_node, FindDCIByDescription(mlcNode,dciName));
  return (numImages / numTransactions) * 100;
}
