Double Alerts

[perric]

Hello,

I did a quick check through the forums and didn't see anything on this. I have a service check setup, which provides CRITICAL and WARNING alerts when a value hits the threshold. This works great. See example of the alert below. However, each time, I also get an alert on the host object and the alert for the host is always "Up" and "Ok" with the latest rta and % lost. Is there a way to have it only alert on the service and not the host? I feel like I am missing a setting here, but cannot find it.

Nagios has detected a problem with this service.
Type: PROBLEM

You can always set up what type of notifications you would like to receive for this particular host under the CCM.

Host - notification options

This directive is used to determine when notifications for the host should be sent out. Valid options are a combination of one or more of the following:
d = send notifications on a DOWN state,
u = send notifications on an UNREACHABLE state,
r = send notifications on recoveries (OK state),
f = send notifications when the host starts and stops flapping, and
s = send notifications when scheduled downtime starts and ends.
If you do not specify any notification options, Nagios will assume that you want notifications to be sent out for all possible states.

Example: If you specify d,r in this field, notifications will only be sent out when the host goes DOWN and when it recovers from a DOWN state.

Parameter name: notification_options
Required: yes

Can you post the config for the service please.

CCM > Monitoring > Services
Click the floppy disk icon and paste the text config here please.

lmiltchev - thanks for your response. You provided host alert settings, but this is a service check. To rephrase my question, why am I receiving "host" alerts, when my "service" check reports a WARNING?

Box293 - Below is the config for the service, as well as the details for two nested templates being used with the service.

In your first post, you said:

However, each time, I also get an alert on the host object and the alert for the host is always "Up" and "Ok" with the latest rta and % lost.

and showed us the service notification. Can you also show us the actual host notification, along with the config of the contact, receiving it (& all associated commands, templates, etc.)? Thanks!

Below are the details of the host object (for this service), the host templates, contact group/contact and check command.

It seems like the "ddutt" contact is using both, the host & service notification handler defined for "service_notification_commands"...

define contact {
contact_name ddutt
alias David Dutt
host_notifications_enabled 1
service_notifications_enabled 1

email [email protected]
pager 9146488046
use xi_contact_generic
}

[perric]

I want to have users like ddutt to receive both host and service notifications. I am not seeing how this is related to the issue?

If there is a service check (for port or interface bandwidth utilization) that returns a WARNING, why should the host send an alert on this same service issue? My hosts are doing an ICMP or ping check, which is completely different and unrelated. Doesn't make sense to receive both service and host alerts, when only the service returns a WARNING and the host check is fine. For reference, here are the alerts received when bandwidth exceeds a threshold:

Nevermind. I didn't see that I had both Host and Service handlers on the service notification configuration. I thought you were pointing out something else.

Thanks for your help. Please close the issue.
