NetXMS Support Forum

Hello, I just migrated our NetXMS instance from 2.2 to the latest version of NetXMS (5.2.1).
Somehow the Event Processing Policy do not send emails. 
First, I had to configure new row in Notification Channels - done.
In the Tools - Send notification - I tried to send me test email - done, email recieved.
In the Event Processing Policy - I have custom event code and server action - send email (called "Network_Device_not_OK").
In the Actions Configuration - I have row "Network Device not OK" with Send notification and correct Channel name (which I tested and recieved email before) with my Recipient's address, subject and mesage text.

I have mailing template which polls ICPM ping packet loss (origin: internal) - last(5) polled values > 99 triggers Event "Network_Device_not_OK "

I can see that in Event Log - correct Event, message, ... But my email is nowhere.
Can you help me to fix that? It was working in previous version.

One more question, do you know how to send emails from template and polled values better than ICMP ping - packet loss? Some devices do not have agents or SNMP configured, so I want to get notified when they go offline (but not all - thats why I use template and apply only to specifiec ones) and also not instantly? Thats why I wait for like 5 polls to notify me.

Thank you in advance.

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 :-)

Somehow service is trying to start older version of server.
Anyway if I run manually netxmsd from console, it load right version NetXMS Server V3.3.315 Build 3.3-315-g5360e23aa3 (UNICODE) Ready
But after a while, there is a SIGSEGV error and it stops.

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:

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.

Ok I solved it :-) I have to change also table charset and fields name charset.

Thank you.

Hello, probably yes, because when I create new data, it changes half of these characters too.
MySQL DB is set to UTF8.

Container names, object names, event processing policy, etc .... work ok with all UTF8 char set without problem.
Strange.

Can you try to write Č OR Ř to Event configuration, refresh it and see if encoding works?

Hello, that was the problem. Thanks.

Now I can see the last UTF8 strange problem, in Event Configuration half of UTF8 characters are changed to ? This is weird.
For example:

ěščřžýáíéůú
is changed to:
?š??žýáíéé?ú

Name of containers are ok. Any idea? Thank you.

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?

Hello, thank you.
I upgraded our netXMS instance without any problems :-)

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

Ok, I solved it by:

return real(GetDCIValueByDescription.....

and also by val1 = real(GetDCI ...

Well,

return val1 / 1000 + val2 /1000 + val3 /1000;

returns correct numbers (/1000 lower ofc), so it has to be something with overflow ...

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
