we did not add any additional memory.

you mention 10000 services, means bandwidth of 10000 ports right??

currently we have near about 2300 hosts(srv, nw, db) and 10000 services also it will be increase till 20000 services and 3000 hosts.

Out from we have to monitor near about 3000 ports bandwidth of 1500 routers. Please suggest will bandwidth monitoring work fine?

As scott said:

This depends on many factors including system resources, network speed, check frequency

We would need to know the number of processor cores or processors and clock speed, drive types and speed, your networks throughput speeds and the frequency at which you would be checking each port.

Our main issue is we are getting below issue while updating mrtg

I'm with Sam, we need to know

Additionally the quantity of memory on the system, and any performance tweaks you have made.

My guess would be it is below the requirements for this many checks

we have 24 cores with 2.4ghz speed for each, more details have attached.

total memory is 32 gb, details are below

we are using 10 minute frequency to check bandwidth services.

one more issue i found, i am getting error when run cfgmaker command but i get output for same router using snmpwalk. what can be issue?

If you have run the wizard before for the switch there will be cached results, there is some documentation on that here

http://library.nagios.com/library/produ ... -or-router

also, how many of those 24 processors X 6 cores are allocated to the XI server?
