NetXMS Forum

The Admin guide says that it is possible to search for MAC and IP addresses known to NetXMS (see  https://www.netxms.org/documentation/adminguide/topology.html#find-mac-address)

Find MAC address

It is possible to find location of any known MAC address in the network. To do this, select Tools ‣ Find MAC address. Results of a search will be displayed in the same results view. It is not necessary that node with given MAC address be managed by NetXMS server, but if it is, appropriate details will be displayed.

Find IP address

It is possible to find location of any known IP address in the network. To do this, select Tools ‣ Find IP address. Results of a search will be displayed in the same results view. It is not necessary that node with given IP address be managed by NetXMS server, but if it is, appropriate details will be displayed.

I am not quite sure when or how does this feature work, since I hardly ever get any result (maybe it depends on some switch FDB or arp table or topology information, .... ).
Most likely it does not show any results for nodes and interfaces that exist in netxms and the router these nodes are connected to is not monitored by netxms. At the end it looks as if netxms is unable to find IP or MAC address that the user can see on the screen

See the screenshots (version 2.0.6)

Any chance to fix it or at least clarify conditions when it should work?

Thanks and Regards,
Lukas

There seems to be some problem with the library that is used for map drawing - see https://www.netxms.org/forum/general-support/no-tooltips-on-map-icons-in-the-web-console/
AFAIK not much has changed since that time.

Netflow data analysis would be great, but I do understand that even basic implementation can be quite demanding task.
Is this the part that is already implemented http://git.netxms.org/public/netxms.git/history/HEAD:/src/flow_analyzer?js=1 ?

Which protocols are other users mostly interested in?

• sFlow
• NetFlow v5
• NetFlow v9
• IPFIX
• some other?

Thanks for the info, docker-compose seems to be the proper and convenient way to have all-in-one solution

I am sorry, it was my mistake - of course I had another netxms server running at localhost listening at all interfaces It is pity that the error message is not more descriptive.

So now it works like a charm.

A bit more step-by-step guide for docker newbies (like me:)

# open your X-server
xhost +
# start container and give it some descriptive name so we can refer to it later
docker run --name=netxms-server-latest  lomo/netxms-server

# show me the container IP
docker exec netxms-server-latest ip a

# check that nxadm does something
docker exec netxms-server-latest nxadm -c "show stats"

# start nxmc
docker run -ti --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix lomo/netxms-nxmc
# login to server IP displayed in step 2 (172.17.0.2) as admin:netxms

Thanks, very nice and convenient for showing live preview of the latest version without much hassle 

Currently the netxms client reports

org.netxms.client.NXCException: Server uses incompatible version of communication protocol

Is it just a temporary problem caused by the fact that both images come from the latest build and  they may have different version information?

Hello,
Is there a way to create multiple links between two objects on the same map?

This forum post (https://www.netxms.org/forum/configuration/network-map-dual-link-on-same-object) suggests that it should be possible - multiple links are created and bend point routing needs to be used so the links shape can be changed. It does not work for me - I am unable to add second link between two objects in 1.2.14, web console.

Is it a bug or feature?

Regards,
Lukas

Hello,

Netxms allows me to set the system right "Control user session" https://www.netxms.org/documentation/adminguide/user-management.html:

Control user sessions -  Allow user to see active user sessions and force terminate them.

So far I could not find any dialog that allows me to see and terminate other users sessions. Is it a reference to an unimplemented function or is it really there?

Thanks and Regards,
Lukas

If you applied instructions for changing tools.cpp exactly as there were described then you are still using the old version - make and make install needs to be done after you change the file, not before.

HTH,

@kozlov_ao said in Netxmsd 1.2.13. Segmentation fault:

2 vgourov:

1. get and unpack new package (1.2.13)
2. run ./configure with needed paramert
3. run make and make install
4. after installation, copy new file tools.cpp (https://www.netxms.org/forum/oe-oo/netxmsd-1-2-13-segmentation-fault/?action=dlattach;attach=1696) to src/libnetxms
5. run make install in src/libnetxms

I think that step 4 should be done before step 3 (make && make install) in order to apply changes in source file. Command make install only copies compiled files to proper locations.

Thanks for the reply. I will see what we can do with it

Hi netxms users,
I wonder if someone is using netxms with disabled function that deletes events and alarms for deleted objects (server config variables DeleteEventsOfDeletedObject and DeleteAlarmsOfDeletedObject).
If you keep events and alarms related to deleted objects, how do you search for these events and alarms in event and alarm log if you want to find some info about deleted object? How do you know what was the source of event and alarm if there is only object id and no object name?

Why I want to know that: user wants to know what was the alarm state and events related to objects that were deleted during the last month because there are some questions regarding SLA. Not deleting any objects would be obvious solution but unfortunately not possible in this scenario.

 Thanks and Regards,
 Lukas

Thanks for the reply.
It seems that tooltips for web UI were not implemented in zest yet.  They have an open issue for that: https://bugs.eclipse.org/bugs/show_bug.cgi?id=351288.

Hi,
I just realized that management console provides nice and very useful tooltip for all objects on map. Unfortunately this feature seems to be missing in the web console. Is it intention due to some technical limitations, is it necessary to enable it somehow or is it simply forgotten? Important parts of the code for tooltips seems to be there.

Thanks,
Lukas

Thank you Victor for a detailed explanation, it's very helpful.

Hi,

Are there any known or recommended values for DCis monitored on the management node? Is any of the following parameter worth watching and having a threshold alert defined?

So far I was able to come up with the following "rules", but I not sure if this is correct. Also some data are missing:

• "Configuration poller queue for last minute" --  depends on server configuration value NumberOfConfigurationPollers
• "Status poller queue for last minute" -- depends on server configuration value NumberOfStatusPollers that should be 1/10th of Nodes.
• "Average time to queue DCI for polling for last minute" -- will increase if DCI polling takes more time - rule should be that (avarage time * number of DCIs) / NumberOfDataCollectors < DCI polling interval
• "Database writer's request queue (other queries) for last minute" -- this and following two are influenced by NumberOfDatabaseWriters server configuration value, but I am not sure when this value needs to be increased.
• "Database writer's request queue (DCI data) for last minute"
• "Database writer's request queue for last minute"
• "Data collection poller's request queue for last minute" -- probably depends on NumberOfDataCollectors and "Average time to queue DCI ..."

Can someone add more info from larger deployments about acceptable values?

Thanks and Regards,
Lukas

"Database Connection Pool exhausted, fallback connection used" is more like a warning that the connection pool has insufficient size and additional connection to database needs to be established. Maybe it is a consequence of some other problem, but as far as I know, this alone should not cause client request timeout.
 
Size of the connection pool is controlled by server configuration variable ConnectionPoolMaxSize, message should disappear if you increase it.
When I leave it at the default size, this message appears about 5 times during the netxms start in my setup.

Hope it helps,
Lukas

Nice.
What can we expect from the feature called "XMPP messaging support"?

Best Regards,
Lukas

Can you provide some context information?
What are those .bit files suppose to contain? Which OS?
