Nagios Support Forum

Does it mean that in addition to providing all of the required args for each of the commands manually, I also need to do it manually for every single host???
Don't you have a standard type of arguments that work for each of the commands passed and then each Admin can tweak them as they want?
I think most Linux Admins are looking for the same thing from nagios software -- to get performance statistics about their remote hosts (like CPU usage, memory/swap utilization, I/O, disk space monitoring, etc.) with the nice graphs.
Building every single command manually and testing it is a way too much time for Admins! Don't you agree?

After removing extra " /" from each command (bug in a wizard), I get the following output that I need to tune manually each command (except "ping" and "disk space" that work with default settings):

Thanks for your replies!

I guess it comes down to what do you want to monitor and when do you what is considered critical to your organization?

Out of curiousity, where did you get the list of commands you are using? I know that a couple like "Ping" and "Root Disk Space" were defaults in the wizard, but how about the rest?

For example, check_breeze:
This plugin reports the signal strength of a Breezecom wireless equipment

Are you monitoring Breezecom wireless equipment from every host?
What Percentage strength is a good warning threshold for your organization? 70? 80?
What Percentage strength is a good critical threshold for your organization? 70? 80?

These are decisions that are usually made by the admins, once. Once you know what you are monitoring and what is the correct levels you want to use system wide, you can use the same values for all of your servers if you like.

More examples:
check_log:
This takes a logfile as a command and searches for a pattern.

There is no way for Nagios to give you pre-defined values for this...

check_mrtg:
This plugin will check either the average or maximum value of one of the two variables recorded in an MRTG log file.

No way for Nagios to know the name of your mrtg log file and what values you are looking for.

Here's some common one
Check Users Check Load Check hda1 (but your drive may not be name /dev/hda1) Check Zombie Procs Check Total Procs

Scott, thank you very much for detailed explanation and all your help throughout the setup process!
You guys are doing great job considering you communicating everything by mail only.
Why not have the phone support as well? Those type of explanations would save a lot of time for Nagios users as well as support team.
Based on your quote below, once I define my commands for one remote host and I want to duplicate those commands on 10 more hosts,
is there an easy way of copying those commands with arguments to other 10 hosts without retyping manually every single one?

One of the additional features we have for customers is the bulk host import wizard. How this works is you setup one host with services the way you want, then you run this wizard and tel it what host to copy, give it a list of IP's/hostnames and it replicates the setup for all of them.

We are working on this as we speak, however I don't have detail about when it will be deployed or what the price will be for a phone support contract.
