NetXMS Support Forum

Are you guys going to release any documentation on setting this up ?  We have a use case where we have some modbus devices and using modbus2mqtt  we would like to log that data in netxms



Thanks,

Gary Bonner

Just curious.. I see experimental mqtt support was added and looking at the source it is only listed under subagents.  Is both the broker and client running on the agent ?   Just trying to figure out the topology of this. Does the agent publish predefined metrics to the server ?



Thanks,

getting the following when trying to install..  this is on a Ubuntu 16.04 system installing from source

I have several switches that Netxms  2.0.5 is communicating with SNMPV3   I have seen this issues more than once but never thought too much about it but now its becoming a pain.  For some reason after configuration probably after the configurations polls are executed netxms  sees these layer 2 switches as having agents   which breaks any DCI and summary tables these are associated with..  Any suggestions as to how I can stop this or is this just a bug



Thanks

Is it possible to launch on demand topology polls and network discoveries via the command line ?

Is it possible to get snmp values via nxshell ?  I need to get the serial numbers for a certain type of switch and the only way is via snmp




Thanks

Can we start a thread or a place for people to post scripts.  I think it would be useful..Im sure there are alot of people that have scripts that could be useful for new comers or some that maybe trying to do the same thing.





Thanks

i dont see any documentation for zeromq.. is this going to be used for pub/sub to alarms or will it be able to do api calls to the server using req/resp  and any zeromq client.

Is is possible to cause a node to go into critical or down status based on the results from icmp stats.  I have a subagent setup to monitor latency of several hosts  but when the threshold is met the alarm is generated for the agent and not the instance being monitored ..  I would like to generate  a critical or down status if the latency shows 10k  for that particular instance   

It would be nice to be able to assign nodes to users... So if you have user Tech1 which is only concerned with servers. You can select which servers he should be able to see Alarms for and only those. And Tech2 which is only concerned with PC's  he only recieve alarms for those selected

Is there a way through scripting or other to do checks on nodes that dont either support SNMP or Agent  but have ssh access.   Since ssh supports running remote commands such as  if i run "ssh me@remotenode uname -a "  will give me system identification info  could I create a DCI that could run these remote commands via SSH to gather data ?  I have a switch that does not fully support SNMP and  only way to gather interface,cpu or temp stats is either via web or login and run a custom executable which comminticates with switch chip ...so my only options is try and scrape the data from the gui or run the custom commands over ssh and return it to NETXMS but i dont see any way to do that in the DCI setup options...



Thanks

For any one interested I compiled a Agent that will run on a Ubiquity Edge Router/Lite products ... I currently use these as Pollers to proxy snmp or icmp polls  to ease the load on the main server. They also act as distribution devices to the field so it helps to be able to get interface BW and CPU usage for a segment .. Also here is the script that i use to assign nodes to these so i dont have to go one by one ...Just grab the object id of the poller and add the object names in the .txt file   You will have to scp the deb file to the router then run sudo dpkg -i netxms_ubnt_2.0.5.deb to install this will install to /usr/local  and config files to /etc/nxagentd.conf   also you will need to run "sudo ldconfig" after install or else you will have errors when attempting to start  with  "sudo service nxagentd start "  You will also need to vi the nxagentd.conf with your own params....  Hope this can be useful to someone


from org.netxms.client.objects import Node

for name in open("snmp-proxy.txt").readlines():
    node = session.findObjectByName(name.strip())
   
    if node:
        md = NXCObjectModificationData(node.getObjectId())
        proxy = 10254
        md.setSnmpProxy(proxy)
        session.modifyObject(md)

Question I currently have a server ubuntu 14.04 with netxms 2.0.1   I have purchased a newer server and want to migrate all data to the new server which is ubuntu 16.04  but I want to install the latest Netxms version 2.0.4   can i simply install the new version and dump and restore the data base using mysql tools or do i need to do this using nxdbmgr  and what is the difference between using nxdbmgr vs mysql dump  does dbmgr only grab the schema and not the data ?



Thanks

Just curious what versions of WRT is netxms agent compatible with ?  I tried to build it on 15.05 and got the following

Greetings,


I have a script which sends data via nxpush to a DCI and i have noticed that it takes almost 30seconds for the dci to reflect the changes ... is there a way to specify the time stamp using nxpush instead of having  time stamped by the server when it is recieved

Is it possible to assign  data points to the line chart  maybe with a dot or something visible.  It is hard to distinguish  visible changes on the line when there are only slight changes in the data which almost makes it look like a single line that continues to rise slightly

Does the Dashboard web page element use a internal browser ?  And is there a way to tell it you use a local browser like chrome or FireFox when rendering web pages



Thanks

Is it possible to configure snmp proxy via nxshell  I see that its is possible during creating but what about after the fact



Thanks

I have a layer 3 switch that has several vlan interfaces and netxms has created a new node for each vlan interface  so I have  six nodes all named  L3SWITCH_TEST  and each node has all the same interfaces duplicated the only thing that is different from each node is the id and primary host name which is the vlan interface ip.



Is there a way to prevent netxms from creating all these unnecessary nodes? or does it even matter  ?  I just dont want multiple duplicated checks on the same switch


Thanks
