Planning Hosts, Host Groups and services

[yosh]

Hi All,

I want to know the best and recommended way of planning Hosts, Host Groups & services.
For instance, lets say I have hosts A, B, C, D, E to monitor and Im going to monitor the CPU load of each host.

There are 3 ways that I can think of planning the Hosts, Host Groups & services to fulfill above requirement.

Method 1:

1. Create 5 hosts.
2. Create check load service
3. Attach check load service to above crated 5 hosts

Method 2:

1. Create 5 hosts.
2. Create a Host group and attach above 5 hosts to the created Host Group
3. Create check load service
4. Attach check load service to above crated Host Group.

Method 3:

1. Create 5 hosts.
2. Create 5 check load services in services config page (a check load service per each host)
3. Attach each check load service to its designated host.

From above 3 methods could you please advise me, which method would be optimal ?
Also if there's any other better way of doing this apart from the above mentioned 3 methods please let me know.

Thanks.!

I think this really depends on if you want to use the same threholds from check_load to the 5 hosts?

If you are using identical services with identical thresholds then Method 1 or 2 is what you want.

Method 2 --> is almost the same as Method 1 because you are assigning that check to those hosts.
It saves time, and if you this check_load is going to be identical then why not create only 1 service and apply to them all.

Method 3 --> makes managing thresholds easier in my belief. What if one host experiences more load then others?
