Let us take a closer look at how to acknowledge an alert in Nagios with the support of our Server management support services at Bobcares.

Acknowledging an alert in Nagios

When a service problem is acknowledged, further problem notifications are temporarily stopped until the service changes from its current state.

In this post, we will learn how to acknowledge difficulties with a host or service in order to prevent further notifications and to indicate that the problem is being addressed. If more than one administrator has access to the Nagios Core web interface, this is useful.

This procedure can avoid several administrators from attempting to resolve a problem, as well as unnecessary alerts for a longer-term issue once the operations team has been made aware of it. The precise modifications in behavior caused by the acknowledgment are defined at the moment it is submitted.

How to acknowledge Nagios alert?

Access the Nagios webpage from a network-connected machine. Once logged in, click the host groups link on the left side of the browser window.

This will open a page with a list of all host groups and their associated hosts. A services column can be found in the host table. If there are any problems, the services column will show how many services are critical or experiencing problems.

Then, proceed as follows to acknowledge an alert in Nagios:

• Check the ‘Sticky Acknowledgement’ button if we want acknowledgment to disable notifications until the service recovers.
• Contacts for this service will receive an acknowledgment notification, letting them know that someone is working on the situation.
• In addition, a comment will be added to the service.
• In the remark section, we may also write our name and a brief description of what we’re doing.
• Check the ‘Persistent Comment’ checkbox if we want the service comment to stay after the acknowledgment is gone.
• Uncheck the ‘Send Notification’ button if we do not want an acknowledgment notification sent to the right contacts.
• Then, to save the acknowledgment, click commit.
