NetXMS Support Forum

Hello,

I have very old version of NetXMS and I would like to update it to the newest version. Is it possible to install fresh server with latest version and migrate DB from 2.2.10 to 4.X?

If not, does anybody know how to fix this error when I try to update it via apt-get update on old version of debian?

/var/lib/dpkg/info/netxms-server:amd64.postinst: 89: /var/lib/dpkg/info/netxms-server:amd64.postinst: /usr/bin/nxdbmgr: Permission denied Or when I try to compile it manually via

sh ./configure --with-server --with-mysql --with-agent --enable-unicode --with-pcre=/opt/pcre/lib64
configure: error: libpcre32 is requred which I have installed before

Thank you very much :-)

Hello, I upgraded from scratch our NetXMS instance from 2.2.10 to 3.3.315 on Linux debian
nxdbmgr check OK
nxdbmgr upgrade after 10 days OK
nxagentd run ok

When i run service netxmsd start
it says running but in /var/log/netxms.log I can see Errors:

2020.05.18 08:08:03.608 Log file opened (rotation policy 2, max size 16777216)

When I restarted server and these services are autostart, it started server somehow with same error:

But all values and history on nodes are empty, even netxms server node is saying there is running agent 2.2.10.
Somehow DB is for 3.3.X and server instalation is older.

Any tips how to fix this?
Thank you.

Hello, after update to version 2.2.10 I am experiencing problem with sending duplicate emails.
I checked configuration and it seems there should be only one email when node goes down or up.

The time difference between both e-mail is from 1 sec to 1 minute and the interesting point is that I have been playing with some UTF8 changes in emails body and one email is without UTF8 characters and second one is with UTF8 char. When I check Actions Configuration, I can only see that email skeletons with UTF8. There is also only one Action in DB, so there must be somewhere problem but I don't know how to debug that. Any idea? Will Syslog Monitor help or where can I see processed e-mails?

Thank you in advance.

Hello, I recompiled server to UNICODE and changed my MySQL DB to UTF8 but when I try to receive some UTF8 mail, it skips all these characters. Can anyone tell me how to diagnostic this behaviour or what needs to be configured more?

My settings:

NXCP: 4.48.1.14 (AES-256, Blowfish-256, 3DES, AES-128, Blowfish-128)

Hello,

is it possible to update from 2.0.8 to latest version directly or I should I update to 2.1 first?
Thank you.

Hello,

we would like to monitor some of our critical infrastructure via another network interface. Is it possible to add 2nd interface and somewhere set NetXMS to monitor some specific servers only via this new network interface?

Thank you

Hello guys,

I have one question about scripting in NetXMS. I wrote script, which simply sum three values and return this result.

val1 = GetDCIValueByDescription ...
val2 = GetDCIValueByDescription ...
val3 = GetDCIValueByDescription ...

return val1 + val2 + val3;

When I return val1 or val2 or val3 it returns right number, but when I sum these values, it returns negative incorrect value.
For example val1 = 200.50 val2 = 700.56 and val3 = 1500. When I sum it, it returns -1400 ... That's very strange ...
I thought it could be due to overflow of float value, but somehow it works correctly on different servers with higher values.

Any idea how to solve this or debug this?? Thank you in advance

Hello,

I draw some graphs of memory usage and I would like to subtract values from Memory free value.

For example: System.Memory.Physical.Used - System.Memory.Physical.Buffers - System.Memory.Physical.Cached to get real used physical memory.

Is it possible to subtract these values in Transformation? If so, how can I call these values? If not, what is the best way to do that? I am new to NetXMS so I am little confused. Thank you :-)

Hello, I would like to share some network maps to some users for read only. When I set up access rights in Access Control and user log in to netXMS web interface or Management console he sees network map with Unknown icons instead of devices icon.

Check attachment for an example.

Do you know how to fix it? Thank you

Hello,

I have 5 similar servers running the same Windows version (Windows Server 2012 R2), same NetXMS agents version with the same subagents. One of these servers is reporting error when I am trying to monitor interface traffic via Net.Interface.BytesOut64(*).

Error :Status of DCI 617 (NetXMS Agent: Net.Interface.BytesOut64(Ethernet)) changed to UNSUPPORTED"

Interface name is correct, do you know where could be the problem? I am also experiencing this problem with one Windows 2008 server, but I guess it could be caused by old system.

Thank you in advance :-)

Hello, is it possible to monitor memory usage on server per logged user via SNMP or NetXMS agent?

I have terminal server and I have installed NetXMS agent to run per session, but I can't figure out how to do that.

Thank you guys :-)
