Hello Benjaminsmith,
Can you please let me know do i need one more new license of Nagios XI server ( cause you have suggested we have 1,49,424 passive checks on my machine) or can I upgrade my hardware(CPU, MEMORY & HDD) & run 1700 hosts on one machine?
Cause still there is delay of 20 minutes at front end.message queue is decreasing slowly.

Hi Jatindeepsharma,

I would reach out to one of our sales engineers ( email sales@nagios.com ) to help you with these questions as it is more related to costs. You have to consider that the cost of expensive physical hardware vs purchasing another license and using less expensive hardware or a VM.

I am good with buying a license which could handle my 3500 hosts & provides me real time SNMP alerts. Please help.

Hi JD,

The last profile you sent me had 16GB of memory. Can you send over the latest profile since increasing the number of CPU Cores and RAM?

We don't see XI systems running 149K service checks, but having everything setup passively makes this possible. We recommend getting another license after 20k checks.

Once more item, if you have not optimized the PHP settings please follow the article below:

https://support.nagios.com/kb/article/n ... e-611.html

This will help with any timeouts and allow PHP more access to system memory.

Hi JD,

Did you increase the PHP settings?

For some reason, the system profile only had 4 files and didn't complete. However, the top command is looking much better.

The bottom line here is to increase the resources on this server and adjust the settings to maximize the performance. If you need to add more hosts and services, you're going to need another server. If you do get an additional server, you might as well move some of the checks over to distribute the load among the 2 instances and avoid any lags in the GUI.

Hi @Benjaminsmith
I have some queries, Can you please help me with that?
1. Is it possible if i will increase number of CPU cores(16),Memory(32GB) & HDD (2 TB) on same VM machine & run new extended NAGIOS XI licence which can hold up to maximum number of hosts. (i.e. upto 3000 hosts) rather than get it on another VM.
Reason to add resources on same server is that i don't want Nagios on 2 machines.

2. By decreasing number of services( which were 149K at first), will it also increase productivity of my server?


Regards
JD

Hi JD,

1. As mentioned, I would reach out to one of the sales engineers at Nagios as they can provide more information about server sizing. We also have Nagios Fusion that can provide a centralized view for multiple XI servers, if you would like to add more servers and also have a centralized view of the status.

https://www.nagios.com/products/nagios-fusion/

2. Yes, decrease the total check load ( hosts + services). If you are running active checks as well, implementing Mod-Gearman will help offload the processing. However, this will not be much of a benefit for passive checks.
