NetXMS Support Forum

Hi,

One more question about snmp tables:

I'm monitoring rmon statistics on switch,as rmon doesn't show real time packets i'm getting the total amount of packets or errors etc.! What i want to do is set a delta value threshold,to know whether the amount of packets in certain period of time have reached the threshold. Is that possible now, As i don't see anywhere to set delta value?

Thanks in advance,
Nikk

Okey, thank you!

Can't wait the next release!

Nikk

Okey, i'll try that patch, and will let you know about the progress!

Nice to hear that, big thanks!

Hi,

I'm experiencing problems with two netxms servers.

Problem 1.

NetXMS running on VMware Windows server 2012.

Starting server takes about an 20-30min, first time it occured is when I raised the datacollector amount by 5! I lowered back to default amount but nothing, then I thought maybe it's because of SNMP tables or logwatch scripts which I added, but when removing all of that, anyway the same problem.
I just get - Error 1053: The service did not respond to the start or control request in a timely fashion.
and after a long time it starts. Nothing in logs but something i got in crashdump:

I'm getting segmentation fault, strace:

And in management console more than often i get Software caused connection abort: socket write error and then i must restart console to be able to do something again.

And, once I exported a template from server, and know, when I want to import it back, I get timed out, and  timed out on everything. Here is trace:

Is the template wrong, or is there something else?

Thanks in advance,

Hi,

When creating DCI (snmp) table I wanted to add thresholds. As i noticed under Conditions there is window with empty dropdown menu! Is this how it should be - I enter some value - or there are missing some things like (functions in standart DCI threshold) 'last polled value' etc..?

And that snmp table error, whenever I make a mistake, I must restart the server, is getting annoying :/

Thanks in advance,
Nikk

I had the same message, and i just changed the mib extenstion to .txt and everything went without errors!

Hi,

So here are latest Enterasys mibs http://www.enterasys.com/support/mibs/

And i added snmpwalk from older (c2) and newer switch (c5).

I will talk with my network admin about accessing real device, probably we will manage something out

Thanks in advance,
Nikk

Hi,

Thank you, it worked fine

Nikk

Hi,

As our company are mainly using Enterasys devices it would be nice if you could add NetworkDeviceDriver for Enterasys switches.

Thanks in advance,
Nikk

And so again server just stops working, but this time after trying to import configuration!
Tried to import Availability template from https://www.netxms.org/forum/general-support/sharing-standard-templates-for-netxms/

From server I get -  'Import Configuration' has encountered a problem. Cannot import configuration: Request timed out.
But crushdump is empty.

Nikk

Hi,

Sorry for delayed response!

Yes, I was using SNMP tables! It would be nice, thank you!

Nikk

Hi,

At first good news, out company decided to use NetXMS as our main NM, so I am looking forward to further collaboration.

And the bad news, as I was messing around table DCI's, suddenly the server crashed and I'm not able to connect to server anymore.

I'm using Windows server 2012 on VMware.

From eventlog:
The NetXMS Core service terminated unexpectedly.  It has done this 13 time(s).
Faulting application name: netxmsd.exe, version: 0.0.0.0, time stamp: 0x5245b009

And I also sent the crush dump results to [email protected].

Thanks in advance,

Ok, and one more thing, I don't quite understand how external parameters work.

All information i can get from a node is listed under NetXMS agent, SNMP and WPC right?
So I just make data collection script, and it works just like that or there must be something underneath? Do I make somekind of reference to existing parameters in script or it can be even not related to them?


Thanks in advance
Nikk

So, if i'm right, then with appropriate knownledge, I basically can get any information I want?

Thanks in advance,
Nikk

Hi, I have been evaluating network management softwares for my company and I have reduced the number of NMS from 10 to 2, and one of them is NetXMS. And I'm really looking forward to start using it. But for the guys who decide it, i need a little more information about NetXMS to prove it's more usefull and secure than the other one.

As I wasn't able to find any good information about this I came straight here for help.

So i would like to know:

1. What are the limitations of transformation scripting, or I just can make whatever I want?
2. How much can we customize or adjust NetXMS to our needs, i.e., if we are not using standart enterprises or we need data, that origins do not provide, can we adjust NetXMS to start monitoring them? Like Enterasys, Mikrotik switches and all kinds of databases.  And if I add the necessary mibs, will I be able to get information about all the oids? Basically, i want to know whether we can get out other than standart information provided by NetXMS agent or not and if yes, then what are the limitations.
3. How secure is NetXMS? How secure are the connections between remote places? What security protocols are used? I read that NetXMS is using encryption, but I wasn't able to find any other information about security.

I hope, you can answer to these questions and if there are any uncertainties, please ask!

Thanks in advance,
Hopping, soon to be the new NetXMS user, Nikk
