NetXMS Support Forum

forgot to mention it takes about two minutes or so for the server to even start and after that I get a hole bunch of events complaining about nodes being down in the gui

Is netxms capable of handling 2000+ monitord nodes ?   I have a dual 4 core server with 20gigs of ram and netxms seems to be choking  I constantly get down events of devices that are not down .. it seems its not handling this very well    What would be the suggested variables for such a setup ? Im using percona server for the db which is supposed to be a more optimized mysql replacment....



Thanks

Cool... Thank you for the info

Did some of the configuration variables change ?

NumberOfStatusPollers    If you plan to monitor large number of hosts, increase this parameter from the default value to approximately 1/10 of host count.
NumberOfConfigurationPollers    If you plan to monitor large number of hosts, increase this parameter from the default value to approximately 1/20 of host count.


I no longer see these in the configuration and if things did change could you make a list of what changed or whats new ?

So then am I out of luck on this one

Target is MIPS32 24KEc  and gave the wrong gcc version its actually 4.1.2    I noticed it complains generally  around building and linking libnxsnmp... I dont need the snmp library tools at all just the linux subagent since I only want it to send the linux stats and be able to send a remote command to the device when needed ...

Need help with this i am trying to cross compile just the agent for a device that uses an older kernel 2.6.26.8  with gcc version 4.2.1  and always have issues with  __sync_add_fetch_4  error and I know it is becuase of the older gcc version  is there any way around this ?  This device does not have snmp support which is why I would like to have an agent running on it ...

I have successfully compiled different programs for this devices but having issues on netxms agent


Thanks

Is the also a solution for this topic

im still hesitant to upgrade to 2.0 because i really dont want to have to reset over 200 switches  due to the  wrong community string being sent out repeatedly

Works like a charm ... Thanks

Alex,

what you provided is great ... However how would I tweak this tool to provide the same functionality as  Find Mac address tool in the managment console  which also provides the switch and port the mac is connected to..

oh wow you saved me so much time ... Thank you so much

I think you are still experiencing  this issue https://www.netxms.org/forum/configuration/snmp-credentials/  I dont think the patch fixed this particular error where even though snmpv3 credentials now work the server is still sending out some requests with public as default ..  I am seeing the same thing on my test switch snmpv3 and v2 works great now but I am still seeing snmp auth failures  about 100 a day but on our switches there is a threshold that can be set  I think the default is 10 failures in a minute before its stops responding which i increased untill this gets fixed ....

Exactly as Borgso said..  I generally use mosquitto which is an opensource broker written in c   http://mosquitto.org/download/  there is also http://emqtt.io/ which is written in erlang  both brokers support websockets so you could have realtime dashboards so basically you could create a dashboard and have it subscribe to realtime data  and with the broker being integrated on the server you could just use a local client  https://github.com/eclipse/paho.mqtt.java  ( Java Client)   http://www.eclipse.org/paho/clients/c/embedded/ ( c++ Client )  to subscribe to the topics locally.. And if another Netxms server where interested in the data it would just need to subscribe to the topic using any of the above clients or simply bridge the two with a broker to broker bridge..

nothing special just added all the required packages to compile and compiled on the device ..Im trying to to either do a static compile or create a deb package but im having trouble.  The static compilation fails and if any one has some good docs on building a deb please let me know. but other than that it works great no problems at all

maybe add support for mqtt in order to recieve sensor and other data easily with out having to compile nxevent etc for embedded devices..
