Hii team, i want to reduce load on my nagios XI server for that i want to use Mod-Gearman.

I have read your document of installing mod-gearman. but i have some questions,

1 > i have to install mod-gearman on every server to get data?
2 > what are the H/W requirements for mod-gearman?
3 > can i use the same key of nagios Xi (Unlimited Nodes) in two different server of my Infra?
4> I want to Reduce load on my nagios XI server by using any tool (Mod-gearman like) which collect data of many server and give it to nagios XI server.
5> How does the High Availabilty feature of Nagios Xi work please explain?

You should install mod_gearman in worker mode in those servers from where checks should be made, and only one gearmand module in a centralized server. You can also install both server and workers on a single machine.
Dont know hw reqs, but lower than nagios itself

means if i install mod-gearman in server mode on a centralized server it"ll collect all data of the that N/W & send it to Nagios XI server.

1. You would have to install the Gearman server on the Nagios XI server and the Gearman workers on remote systems. That way, the workers will run the checks, report back to the Gearman server (XI) and then the Gearman server reports the status to XI.
If you have multiple XI servers that you need to reduce the load, you would have to load the Gearman server on those servers as well.

2. I couldn't find any specific hardware requirements for the Gearman Workers but all they are doing is running the checks and reporting back the status so it doesn't need much for hardware.

3. You would have to contact the Sales Department at [email protected] for the details on your license so you can determine if you can install XI on 2 different production servers.

4. Can you provide more details on this? Are you looking for more ways to reduce the load on the server? Have you seen this document?
