no new network creation

Does it still happen?

Can you please provide:
- Output of nxget command line tool, getting interface list from one of sutch nodes. Example: /opt/netxms/bin/nxget -l 192.168.100.5 Net.InterfaceList
- Does all nodes in this subnet have the same same OS?
- Network mask.
- And server log on debug level 6 when one of thoose nodes is status polled.
Recently we had problem with subnet defenitoins for old Windows versions: https://www.netxms.org/forum/configuration/invalid-network-mask-4369/msg20773/#msg20773

So you don't have any agents there(I mean even SNMP)?
Steps to get debug log:- Set in server configuration file this parameters:
LogFile - path to server log file
DebugLevel=6 - Restart derver
- Run manually status poll on one of incorrectly added objects(right click object->Poll->Status)
- Find in lines "Starting status poll for node XXX (ID: NNN)", "Finished status poll for node XXX (ID: NNN)". Send everything between them.
- Set in server configuration file this parameters:

hi Tatjana,
no, no agents and no snmp. do i need to have at least on to be able to create the network ? i thought the network is created when the 1st node is discovered.
see the attached file with the debug output.thank you very much,

Hello Tatjana,
i have installed netxms from scratch including new db and all.
i have configured the "network discovery" to actively search for number of networks that i have and i have created an automatic filter for those networks.
after a day, everything seemed to be discovered but all the nodes appeared after the "network business" icon and again, no network object was created for those networks.i have configured the server to delete empty networks, do you think that something might be wrong there ?
need solution plsRegards,

Hi Victor,
i think i have found the problem.
the nodes are getting discovered as xxx.xxx.xxx.xxx/32 instead of xxx.xxx.xxx.xxx/24 and for that reason it does not create subnets.
what could be the reason ?
what do i have to configure for it to discover nodes as /24 or /22 or any other mask besides /32 ?Best Regards,
Lindeamon

Hi,
yes, for /32 subnets are not created. Those are nodes without agent or SNMP, right? Do you have some subnets that are close to addresses discovered? If yes, what subnets?
Best regards,

hi victor,
yes, those nodes does not have agent nor snmp. those nodes are behind firewall and i just monitor them with ping for the time being until i have the time and the server to do things properly.
by the way, is this a new configuration ? i do not remember having this problems before. do i need to allow netxms to read the firewall/switch tables to be able to discover the nodes with the correct subnet ?
what do you mean by "Do you have some subnets that are close to addresses discovered?" ?
i have 6 subnets and for each subnet i have created an active discovery entry and filter entry. the nodes being discovered are from those subnets.Best regards,

Hi,
could you please provide log for such node for entire configuration poll as well as output from manual configuration poll in console?
Best regards,

Hi Victor,
i have attached the manual full config poll of one of the nodes.
i have discovered that full configuration poll solves the problem.
is this a normal behavior ?Best Regards,
Lindeamon

Hi Victor,
i have run a full configuration poll to all the nodes and they created a subnet for ex. 172.16.1.0/32 and located all the 172.16.1.X nodes under it.
when i run second full config poll, the nodes created 172.16.1.0/24 subnet as it should have been in the 1st place.bits me if i understand what is going on.
what do i have to configure in order for the right subnet to be configured in the 1st place when the 1st node from this subnet is discovered ?Best Regards,

Hi,
if node is first in a subnet and does not have SNMP or agent, server expected to create new /24 subnet (it can be changed by setting parameter DefaultSubnetMaskIPv4). It is definitely a bug, but so far I was unable to reproduce it. I'll experiment a bit more with it.
Best regards,

Hi Victor,
thank you. I wanted to add that some nodes did not registered under the relevant /24 subnet even after 2 full configuration polls.
the only thing that helped is deleting the /32 subnet and the node registered correctly.thank you very much and hope you will find the problem
Best regards,
Lindeamon
