Certain metrics about these applications will probably need to be shared among them, like system load, since they're all on the same server. So what kind of things are you looking to monitor about these applications individually?

Also, if you could provide the following info in your next post that would help a lot: Nagios version, Operating System version, and whether Nagios was compiled from source or installed from a package.

Hi,
Thanks so much for your response. What we actually want to do is to monitor their performance separately.that is,we want to know when any of them is down. For example if iweb is down,we need notification about it and also when all the application are down.

We are currently running in Nagios core version 3.4.1 and running on operating system Solaris 10 by SunOS.

I will be glad if you can assist me in achieving this , so that i can be free from my boss.

Thanks and regards,

If they are all separate processes running on that system, and you would like to know if they are still up or if they are down, you could run a check somewhat like this one with modifications for processes:

There may also be some plugins located at the exchange regarding process checks:

One such as this perhapse?

Thanks so much for the swift response. I don't know how to define the service definition for the four application services. The application was deployed inside web application on Glassfish. Have added the host name. i will be happen if you can tell me what to write on this.
Below is my script

I'm not sure what you are asking here, what else are you looking to add?

[Ladi]

HI Slansing,

Have not define the service name, don't forget i told you that the service name are iweb,imobile,mweb,mmobile which have not define. The only thing i could see that nagios is monitoring on the server is PING, SSH, HTTP ,CPU LOAD AND DISK PARTITION. I still don't know to configure this.

Hope u understand what i want now.

Thanks for your assistance.

[slansing]

Okay I see, I thought you had already defined those, simply look at the definitions and reference them like so:

Code: Select all

define service{
use iweb
hostgroup_name solaris-servers
service_description CPU load
check_command check_remote_load!75%!90%
}

The above will monitor the Host named iweb, and return cpu load information.. if the load reaches 75% it will trigger a warning state change and alert, if it reaches 90% it will trigger a critical state change and alert.

Code: Select all

use = Host Name

hostgroup_name = The name of the Hostgroup which the host is a part of.

service_description = How the service will be shown on the web UI

check_command = The alias for the command being ran, separated by "!" for each argument.

Hi Slansing,

Thanks for your response. That means i have to replicate the configuration you gave me four time. i.e iweb,imobile,mweb,mmobile.

Please would this send me a notification if the services are up and send notification if the services are down too, because that is the major thing or do i need to change the service description and check_command.

I will appreciate if you can send me the type of service_ description and check_command that will be fit in for this service.


Thank for your assistance, i do appreciate it.

[slansing]

I can really only send you what I already have, the command itself, and notification settings would be specific to you. As far as notifications, Nagios will notify whoever you have set up to receive notifications if this service goes down for whatever reason.

If you need any guidelines you can always visit the documentation:
