Bulk Host Cloning and Import

[tonkaUser]

Hi,

I have 100+ windows servers with NCPA agent installed. Some have a single disk C while others have disks C/D or C/D/E.
How can I use a wizard-like bulk clone that will be smart enough to apply space monitoring to only the available disks?

As I see now, I will have to use "Bulk Host Cloning and Import " to clone only servers that have the same disks. Is that true or there's some quick way to import ?

Thanks

Hello, @tonkaUser.

How can I use a wizard-like bulk clone that will be smart enough to apply space monitoring to only the available disks?

I believe there's no such feature available yet. The wizard can determine the target server's configuration only when being ran for each server individually.
The reason why this hasn't been implemented is how would this plugin know if the drive is down versus if it doesn't actually exist?

As I see now, I will have to use "Bulk Host Cloning and Import " to clone only servers that have the same disks.

Yes, exactly, so you'd need to clone the configs to the servers that have same logical disks. Or you may clone one config to all servers and then delete the "non-existing checks".
Or you may assign servers with a similar structure to the hostgroups, and then assign the right service checks to the hostgroups.

Is there a way to do it using config files on Nagios box? Thanks

@tonkaUser, Do you mean by manually modifying the cfg files in /usr/local/nagios/etc/ folder? You could, i'd recommend to import the new config files rather than modifying them. Take a look here:

Just run the NCPA wizard one time against a random host, and it will create cfg files in /usr/local/nagios/etc/ folder, then you could use those files as an example to create new ones.

You could also use a Bulk Modifications Tool. In XI web interface navigate to Configure/Core Configuration Manager, then click on Tools/Bulk Modifications Tool(in the left column). From there you'd click on add services, select the already existing services and clone them for the new hosts. And if you wonder how to add hosts: you could either add them in Core Configuration Manager, or you could use the Autodiscovery wizard that will scan the IP range and let you automatically add all hosts at once.

Are you talking about modifying the configs directly rather than using the CCM? You need to be careful with this, but it can be done: https://assets.nagios.com/downloads/nag ... ios-XI.pdf

I wanted to change *.cfg files under /usr/local/nagios/etc/services and then let Nagios re-process them. I see that my changes are visible, but I don't want to loose them.

When you say change, are you editing the services under a host for example: Editing the check command?

I'm not exactly sure, but this sounds a lot like what @dwhitfield mentioned in the above post.

Be careful when modifying the configs directly, but following the instructions in the documentation he posted is how you do so.

Along with running the commands to make sure your changes don't throw any errors and then restart Nagios.

The following service will check all available drives. One thing is that if there are ~10 or more, the perfdata gets lost.

Code: Select all

define service {
        service_description             FS_Win_Usage
        use                             default_service
        hostgroup_name                  Windows_Physical,Windows_Virtual
        check_command                   check_nrpe!CheckDriveSize!-a ShowAll=long MinWarnFree=20% MinCritFree=10% FilterType=fixed!"perf-config=used.used(unit:G;suffix:'') used %(ignored:true) show-all=long"!-a ShowAll=long MinWarnFree=20% MinCritFree=10% FilterType=fixed perf-config=used.used(unit:G;suffix:'!!!!
        register                        1
        }
