Nagios Support Forum

Hi,
I'm currently finish checking nagios in my lab.
my questions are regarding production:
I'll use centos server based on VM (no resource limitations).

in general I have 3500 devices , 95% are network switch and routers and others are servers.
I use a lot of snmp traps from my devices to nagios server
devices are big, based on juniper mx and cisco...
1. will 1 linux server will be OK to monitor 3500 devices? or I need to seperate
2. in nagios, do I must to buy license? or can I use as a fully open source?

thanks in advance

1. We'd need to know more about the server: https://assets.nagios.com/downloads/nag ... ements.pdf
2. Well, you posted in XI, which will require a license. However, Nagios Core is GPL. Here are the compile instructions for Core: https://support.nagios.com/kb/article.php?id=96

On XI, you'd need the Unlimited node option for that many devices. I would suggest reaching out to [email protected]

hi
thanks for reply.
can Core handle gettinh snmp traps and parse them into alarm?
can Core be used as distributed architecture?

regarding services, can someone help to understand better?
If I have a router with 48 interfaces
I need to collect on each port: util, traffic in/out, error discards
and on the router: mem, cpu and temprature.
so how many services will this router use?
I've understand that one core\xi server is good for 15000-20000 services.

Hi,
I have 4500 network devices
each device has 4-8 ports
on each port I need to check: utill and error\discard
I also need a support of snmptraps from network element to nagios

so my total services are: 4500*8+4500= ~40,500?
so it means I need 3 nagios servers?

can I use nagios core for such a project?
can core get snmp traps? syslog?

thanks in advance.

There's no hard limit. It depends on how beefy the machine is, whether the checks are active or passive, what types of checks they are (python, C, perl, etc), network limitations, IO limitations, and a variety of other things.

That said, our standard response would be 3, yes.

As far as the checks, Core can handle pretty much anything XI can. The main thing about XI is it is easier to set up. I would suggest setting up a demo by emailing [email protected]

Hi,
Just to make sure, when I buy an unlimited license, is it per server or I can distribute them under the same license.
It seems that I'll need ~8 nagios servers with 1 fusion.
So I need to buy 1 unlimited lic or 8?

Any questions related to pricing or licensing should be sent to [email protected]. They can help you decide what license is right for your needs.

OK thanks
