It worked. Great thanks for your support. I think Windows and Ubuntu are good now.

I am glad I was able to help!

Now we have two more issues.
One...we have Fortigate firewall but on the Configuration Wizards there is nothing for Fortigate and I have added it using Generic Network device but it actually did not added properly. Some of the ports are not detected and some of the ports are added but physically these are not exists in Firewall. Is there any other alternate way available to add Fortigate Firewall.

We don't have a wizard that is going to monitor a Fortigate Firewall, however there are some 3rd party plugins on the Nagios Exchange that may work for you. Here's the results from a simple search for "Fortigate" on the Nagios Exchage:

https://exchange.nagios.org/index.php?o ... =Fortigate

Normally, you would try a plugin from the command line to make sure it works. Once you verify that, you would need to add a new command and a service in the Nagios XI. Please review the document below to see how this is done:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

2nd..We have some public IP for WAN connection. I have added one public IP as a host and setup the notification for this IP. I have noticed there is some packet drops from this IP but it does not detect by Nagios. We want if there is any packet drop from this WAN IP, Nagis will send us a notification.

Can you show us the actual command that you are using, run from the command line along with the output of it? Most likely, you would need to adjust your thresholds, so that when packet drop occurs, Nagios will detect the issue, and alert you.

Hi Jeffery,

I will check the plug-ins for Fortigate and will let you know. Regarding the command for WAN IP can you please clarify what command do you mean?

Thanks

You said:

I have added one public IP as a host and setup the notification for this IP

So, if you added a Ping service to this host, and this is what you are using for notifications, we would need to see the service command. You can view it by going to the CCM > Services > <your service> > Edit > Run Check Command. Copy/paste the actual command and the output, and post it on the forum.

If you don't have a Ping service (you only have a host check), this may not work as you might be missing the Run Check Command test button. No worries, let us know what is the name of the host that you are trying to monitor. We still have your profile. We will review your configs, and let you know what command to run.

Hi Jefferey,

Sorry for late response a I was lost my post because of recent change in Nagios support portal.

First screenshot please find the command for host Ping_155.113.
[[email protected] ~]$ /usr/local/nagios/libexec/check_ping -H 127.0.0.1 -w 3000.0,80% -c 5000.0,80% -p 5
PING OK - Packet loss = 0%, RTA = 0.09 ms|rta=0.095000ms;3000.000000;5000.000000;0.000000 pl=0%;80;80;0

2nd screenshot for host "JCA WAN IP" there is no command in service to run.

Thanks

What is your host's IP address? What you are doing here is running check_ping against 127.0.0.1 (localhost) on the Nagios XI server... If you goal is to monitor a remote machine, your command should be something like this:

Code: Select all

/usr/local/nagios/libexec/check_ping -H <remote host's IP address> -w 3000.0,80% -c 5000.0,80% -p 5

2nd screenshot for host "JCA WAN IP" there is no command in service to run.

If the command is not defined locally (on the service level), most likely it is inherited from a template. What you need to do is click on the Manage Templates button under Service Management (the screenshot you showed us). This way, you can see what template is assigned to the "Ping" service on the "JCA WAN IP" host.

Once you see your template on the right hand side (under Assigned), you can search for this template in the CCM to find out what is the command that is used.
CCM > Templates > Service Templates, paste (or type) the name of your template in the search bar, and hit Enter. Click on the template to see what is the check command that is defined.

Note: Sometimes, the check command could be inherited from another template. Other words, there could be a several layers of templates. You can "drill down" in the CCM to determine what command is used for this service. In the CCM, you can define a check command explicitly, overwriting the one that is inherited from the template.

Hi Jeffery,

For Ping_155.113 I don't know why it is 127.0.0.1. I did not added any command manually. I just added the ping service using template "check_ping" and the command added auto. The Nagios host is 192.168.155.73 and the agent host is 192.168.155.113. How can I modify the command.

For JCA_WAN_IP attached please find the screen shot for the command.
[[email protected] ~]$ /usr/local/nagios/libexec/check_icmp -H 127.0.0.1 -w 3000.0,80% -c 5000.0,100% -p 5
OK - 127.0.0.1: rta 0.102ms, lost 0%|rta=0.102ms;3000.000;5000.000;0; pl=0%;80;100;; rtmax=0.194ms;;;; rtmin=0.069ms;;;;

I didn't see any issues with the definitions of the "JCA WAN IP" host, and the "Ping" service attached to it:

Code: Select all

define service {
    host_name                JCA WAN IP
    service_description      Ping
    use                      xiwizard_genericnetdevice_ping_service
    max_check_attempts       5
    check_interval           5
    retry_interval           1
    check_period             xi_timeperiod_24x7
    notification_interval    60
    notification_period      xi_timeperiod_24x7
    contacts                 nagiosadmin
    _xiwizard                genericnetdevice
    register                 1
}

define host {
    host_name                JCA WAN IP
    use                      xiwizard_genericnetdevice_host
    address                  184.67.162.66
    max_check_attempts       5
    check_interval           1
    retry_interval           1
    check_period             xi_timeperiod_24x7
    contacts                 mhossain
    notification_interval    60
    notification_period      xi_timeperiod_24x7
    notifications_enabled    1
    icon_image               network_node.png
    statusmap_image          network_node.png
    _xiwizard                genericnetdevice
    register                 1
}

What kind of issues are you having with these checks?

When you go to:

Home >Details > Host Status > JCA WAN IP
or
Home >Details > Service Status > Ping (on host JCA WAN IP)

and force an immediate check on the host (or the service), does it work?

In regards to the "192.168.155.113" host, and the "Ping" service attached to it, I am confused. You have the SAME config in two different locations - "/usr/local/nagios/etc/hosts" and /usr/local/nagios/etc/services"...

Code: Select all

define service {
    host_name              192.168.155.113
    service_description    Ping
    use                    xiwizard_generic_service
    check_command          check_ping!3000.0,80%!5000.0,80%!!!!!!
    register               1
}

You should have hosts' configs in the first directory, and services' configs - in the second. I have no idea why you would have a service config in the "/usr/local/nagios/etc/hosts" directory. It just doesn't make sense. Are you adding configs or making changes manually, from the command line by any chance? If you do, keep in mind that all of the changes would be wiped out next time you apply configuration. You need to add/configure hosts/services either via config wizards or in the CCM.

Let try the following:

1. Go to the CCM > Tools > Config File Management, and click on the following buttons (in this EXACT order!): Delete Files > Write Configs > Verify Files
2. If you don't see any config errors - Apply Configuration
3. If you see errors, post them on the forum

Hi Jeffery,

Regarding "JCA WAN IP" might be there is nothing wrong in configuration. This is our WAN IP and last week due to some reason there was lots of packet lost for 2/3 days on this IP but Nagios did not sent any notification to us whereas there was notification setup for this. That's why I am confused why it did not send any notification, it should send us notification if there are lots of packet lost in any IP.

I did not add anything from command line. Regarding 192.168.155.113 can you remember when we added this agent first time Nagios did not discover the ping service for this agent and later we added it manually "Ping_155_113" for ping service. Might be this is the reason you see it same configuration in two locations.

I have followed the below instruction and there was no error.
CCM > Tools > Config File Management, and click on the following buttons (in this EXACT order!): Delete Files > Write Configs > Verify Files

Thanks
