Hi community!
I am using netxms for 1 month.
I have lots of (nearly 1100) routers around my country in my network and I am not an ISP :P 
So, I am having problems about my nodes' speeds and statusses. 
Now, these are I can do with this project:
Send e-mail to my ISP about node that is down and at the same time, send sms to my managers about node's status. (thanks for scripting and server side command)
I can see if there is a saturation on any node and can decide easily if the node needs more bandwidth. 
These are what I saw that must be in netxms or I could not do these with netxms :)  (in my opinion)
* In world map view, all nodes' names are visible and this is a disadvantage on networks like mine (nearly all map of my country is full of my routers' names and not all of them can be seen). If an option can be set as SHOW ONLY STATUS INDICATOR, it will be more understandable for people who see my world map. And  if user can right click on this status indicator in world map, and see node's popup menu it will be more usable
* I tried to split Alarms to classes in dashboard. There can be an option here: I can see Object Tools menu in Alarm Browser screen, but I can't see them in dashboard's alarm view section. It will be more useful if it can be add here (for operator's usability).
* As I told above, I can send e-mail to my ISP and send sms to my managers with one command with object tools->server side command option in node's right click popup menu. A little speciality may be added here: Because of I can't use object tools in dashboard's alarm view, I can not send alarm id to my script as a variable. If it can be done so, I could add ack to my script and users could know if this alarm is noticed to ISP. Or if an event object can be add for acknowledgements (ack, sticky ack,..).
* An other thing is : There may be a class as Alarm in NXSL. It can be used for e-mail or sms informations to network operators. For example : If node's bandwidth usage is about max., and if this happens 50 times in a day, an auto message can be send to network operators. Or if SNMP fails about 10 times a day, it can be noticed to network operators by e-mail or sms, too. 
I have about 1000 servers on my network around country and I will try to use nxagent on these servers. I have no idea about nxagent for now, But I am sure, it is very usefull too.
Thanks to everybody in this community. This is a really very good project.
