NetXMS Forum

I have the same problem.Besides, if a switch gets temporarily disconnected from the network and it's not reachable anymore from the seed nodes, it disappears from the map and when it becomes connected again, it reappears in the top left corner instead if the position it had when it disappeared.

Hi,it would be nice if objects on network maps could be "locked" in place, to avoid accidentally moving them while editing the map.Also, it would be very useful if maps had the option to enable/disable the "edit mode" for entire map (same as dashbords).
Thanks,Alessandro

UPDATE: about ten minutes after adding two IP addresses to the MasterServers parameter, the Agent DCI started to work, so the issue is resolved.

Hello,I have a server running NetXMS and NextXMS Agent (v 3.5.90) on CentOS 8, and I cannot get DCI data from the NetXMS agent running on the server itself, that is, all Internal DCI work perfectly, but, for example, the default "NetXMS server: physical memory used by process" DCI always returns "<<ERROR>>" (see first image)

I tried getting the DCI value by nxget and it works only if I use 127.0.0.1 as host address, while it gives "500: Internal error" if I use any of the two "real" IP addresses of the server (see second image).

It seemed like the agent was only listening on the loopback address, so I tried to add the two IP addresses to the MasterServers parameters, in the Agent's configuration file:

MasterServers = 127.0.0.1, 192.168.200.103, 192.168.24.249

and now nxget works with both IP addresses (see third image), but I'm still getting "<<ERROR>>" in the UI.
Am I doing something wrong?

Thanks,
Alessandro

Oh! I'm really sorry, I completely missed this step  :-[ .
Thank you very, very much for your support and for your time.
P.S. I disabled the system user, thank you.

The SQL errors are related to two new groups I was creating (see screenshot), perhaps I made something wrong.
About the autobind script, I don't know, I'm new to NetXMS and I'm still exploring all its features.
I remember opening the script library, perhaps I unvoluntarily tampered with the scripts.

Yes, I can set up a remote access for you, thank you very much.
I have to setup some port forwarding on our firewall: do you only need SSH or also port 4701 for the console?
Can you tell me the public IP address you will be using to connect?

In the meanwhile, I changed the debug level and opened the history and graph of DCI 682 and 683 of node 2069, see attached log.I think they are at line 5744, timestamp 2020.08.11 11:21:55.828

It seems nxshell doesn't get any data too

Yes, of course.

Here they are.

nxmc-metadata-windows7.zip

nxmc-metadata-centos8.tgz

I've not configured many DCIs yet, but it seems no DCI shows historical data.
I've added a couple of other DCI on a different switch (3Com vs CISCO), but still no historical data in the GUI.

Even default DCIs for the NetXMS server itself show no historical data (see attachments).
The only strange thing I'm noticing now, is the <<ERROR>> value for the only DCI coming from the NetXMS agent on the server.

I'm using 3.4.284 on CentOS 8

Today I also tried on Linux CentOS 8, (nxmc-3.4.284-linux-gtk-x64.tar.gz) but nothing changed: no historical data.This is so strange that now I wonder if I'm doing something wrong...

I tried the Windows client (nxmc-3.4.284-win32-x64.zip) both on Windows 7 and on Windows 10, but I also tried the web interface (nxmc-3.4.284.war), everything downloaded from the netxms website, so it seems the issue doesn't depend on the client OS.
I still have to try on Linux...

I tried (see attached config.log), but the issue is still present.
The query is the same as before:

200806 15:54:06    266 Prepare  SELECT idata_timestamp,idata_value,raw_value FROM idata_2069 WHERE item_id=? ORDER BY idata_timestamp DESC LIMIT 4096
                   266 Execute  SELECT idata_timestamp,idata_value,raw_value FROM idata_2069 WHERE item_id=683 ORDER BY idata_timestamp DESC LIMIT 4096
                   266 Close stmt

I was wondering if it could be a client issue, instead of a server one.
After all, if the server had a problem SELECT'ing data from the DB, almost nothing would work...

config.zip

Hi,I followed the directions on the "NetXMS Administrator Guide, Release 3.4.178", chapter "3.6  Installing from sources", that is:

# ./configure --with-server --with-mysql --with-agent
# make
# make install

I'm attaching the config.log and the output of yum list installed.If you need anything else, please let me know.

Thank you,Alessandro

logs.zip

Nothing changed, sorry

Hi,
I upgraded to version 3.4.284, both the server and the management console, but unfortunately nothing changed.

The query is the same:

SELECT idata_timestamp,idata_value,raw_value FROM idata_2069 WHERE item_id=682 ORDER BY idata_timestamp DESC LIMIT 4096

but still no data is displayed in the History view or in the Charts view, and I cannot find any error in MariaDB nor Netxms logs.

Is there anything alse I can try to debug the problem?

Thanks,
Alessandro

Hello,
I enabled query logging on the DB and the query seems to be correct, and it returns valid data (see attachements):

SELECT idata_timestamp,idata_value,raw_value FROM idata_2069 WHERE item_id=682 ORDER BY idata_timestamp DESC LIMIT 4096

I'll try the new version as soon as possible, and I'll let you know.

Thanks,
Alessandro

Hi,
thank you very much for your answer, I checked the DB and the data seems to be there (see screeshots).

Timestamps seem correct too: in the table they're UTC and on the server and client the time is CEST (UTC+1, +2 with daylight savings).
Even if they were wrong, shouldn't I at least see the values in the "History" view, albeit with wrong timestamps?

Thanks,
Alessandro

Hello,
I'm new to NetXMS, I just installed it on a CentOS 8 VM with MariaDB 10.3.17 and it's working fine, but there is one thing I cannot understand.

I configured an internal DCI (ICMP.ResponseTime.Max) and an SNMP DCI (.1.3.6.1.2.1.2.2.1.11.1 - ifInUcastPkts) and they seem to work fine, since I can see the last values.
But when I try to see the History or a Chart for a value they are both empty (see attachments).

Can you help me? Am I doing something wrong?

Thanks,
Alessandro
