NetXMS Support Forum

Hi,

running 3.5.90 and the connection with management is unstable, if i run 'show sessions' in server console the output can stop halfway and then after a while the entire client gets Cannot open server console: Request timed out.
If all the output from sessions is recieved it never returns to prompt need to close the server console tab and open it again to type new command

Hi,

I have a problem that i am trying to understand and see if it is something that can be fixed with config.

When i refresh a dashboard in grafana that has alot of unique DCI values, every tile creates its own session to the server via the webapi meaning you max out available connections to the server and then everything hangs until sessions starts to close.
What i trying to understand if this is how grafana works or is it the netxms datasource plugin or webapi that causes this problem.

If anyone has any knowledge of this i'd be happy to hear it.

Is the driver included in the latest installer the only ncd files i get are these?

Hi,

Upgraded from 3.0 to 3.1 and now grafana can not connect, i have updated both webui and webapi.
The webapi is active but when you save and test in the grafana connector you get "HTTP Error Internal Server Error"

Can not find any logs that shows a description of the error found it

in the webui logs:

Everything runs on the same server, netxmsd, webui and grafana

Edit:

Downgraded the webapi to "NetXMS web service API version 3.0.2296" then it worked again

Thanks for clearing that one up, if it is by design i'll try to stick with it and i kind of got a liking for changing interfaces via object details now

Upgraded server to 3.0.2305 now and in the management console on the nodes in objects the arrow to expand interfaces does not show.
Noticed that the management console is still build 2283 on the download page can this cause this?

Hi,

Do the webapi support table DCI?

I get "Incompatible operation" when adding the table DCI to metrics.

Hi,

Would be nice if you could set a timeout on ExternalParametersProvider so it kills the process if it exceeds this time.

Have a few external sources and trying to get most of them to handle internal timeout but some still hangs at random times and then you have stalled data.

I format mail body with script, event calls mail action and mail action is calling script with %[scriptname] in message text.

if you want event param 2 use $event->parameters[2] in script

Create a string variable with all the text you want then just return it and it will use that for the mail text, for line break use \n

If you are scripting you have access to these to get the data you want also:

I had the same problem when i upgraded from 2.0.8 to 2.1.
I tried upgrading with nxdbmgr and trace parameter (-t) to see more details on which table it has problem with then i restored db from backup, deleted the tdata table it had problem with then upgraded manually.

I also tried ignoring errors (-X) and it worked but i did not trust that but it is something you can try just backup db before.

the db version 410 is because the installer upgrades the DB and fails halfway so thats why you can't use it with 2.0.8.

Same result with just one mib

windows installer

Hi,

I am trying to compile new mibs but it does nothing just prints:

NetXMS MIB Compiler  Version 2.1.1 (2.1.1)
Copyright (c) 2005-2017 Raden Solutions

then stops no error or anything, using same argument line as always: nxmibc.exe -z -d C:\NetXMS\share\mibs -o C:\NetXMS\var\netxms.mib

Any ideas?

Hi,

Is there any way to disable the debug/info logging on the webui?
Running the webapi on the webui server and the logs are getting big pretty fast.

Wonderful, thanks alot had a feeling this was feature related so been looking around
