NetXMS Support Forum

Hi,
i would like to manage UPS that are link to computer where an Agent is installed. I would like to have the infornations when the UPS is connected ( that s mean that power is gone off), and i would like to have also the informations about how many time that the UPS can still works?


How can i do that with the console? I have create a new data collection but it don t work.

Thank you

Hi, i would like to know if it was possible to deploy an xml file on an agent with the NetXMS Console?

Thank you very much

Hello,

• I would like to know how i can do to send alarms or events in the form of SNMP Trap from the Agent?
• Also, i would like to know how we can retrieve a custom attribute when we are on the server and that we receive an event. And how we can show it in the event log?

Thank you very much

Hi,
i try to develop a monitoring in order to retrieve informations about agents. I have installed netxms agent on a computer and i try to communicate with him with an other. the communication between the two works but i have a problem for sending and receiving informations. I have looked at the code already developed by netxms and i tried to send and receive the same type of informations that the agents understand. i have done two files:  One with the code and the other with the include that i need.

Here my file in c++:

When i compile, i have that message:

# ./client3.e
Message envoye par le manager : g
Message envoye par le manager : g
Message envoye par l agent : g
affichage du code du message structure: -809671536
Message envoye par l agent : g
affichage du code du message classe : -809671540

The sending didn t work. can you help me, i am on it for 5 days and i don t know how to do it.

Thank you very much

Hello,

I want to know if there is an API in C to develop our own communication channel with the agents. I mean, without using the dashboard. We have a custom application (for customer use) which does snmp requests to collect information on servers/workstations and we want to use the data collected by GFI Max agents to get more detailed informations that we cannot collect with snmp (like hard drive usage, services running, etc...). Is there a way to do that ? Will there be a way to do that in the future ?

Thanks,
