There’s a new wizard in town and I don’t mean Gandalf the White! The Website Defacement Wizard is a new wizard available in the latest release of Nagios XI 2014.
One of the worst things a company can suffer PR-wise is website defacement. At best, it will require restoring the page, and at worst it can be a nightmare of log review, security patches, and damage control. Time is of the essence in such a situation, so being alerted as soon as possible is of utmost importance. That’s where the Website Defacement Wizard comes in handy.
The Website Defacement Wizard allows you to monitor a web page for certain keywords, either alerting if they are present in the case of offensive or spam-related words, or alerting if they are missing, which may indicate a whole-page defacement. We provide a few pre-defined lists of words you may wish to look for, sorted into categories such as Profanity and Gambling. You can also add your own words or phrases, or remove certain words if they might be expected on the page (such as “unisex” on a page discussing clothing). If you would rather check to ensure the existence of a word or phrase, the process is similar and will be described in this article.
So without further delay, let’s walk through setting up a check:
In the Nagios XI interface, go to the Configure tab and click Run the Monitoring Wizard. Scroll all the way down the page and click Website Defacement.

The JSON CGIs, from the JSON branch of core, have been officially released with Nagios Core 4.0.7!
The original design goals were:
- To provide all information available in current CGIs in JSON format.
- Place the presentation responsibility on the client to minimize network traffic and server load.
- Perform operations on the server side that are significantly more easily done there.
- Spark community developers to create new Nagios Core UI’s from the easy to work with JSON from the CGIs.
The three new CGIs are:
- objectjson.cgi (object configuration)
- statusjson.cgi (status information)
- archivejson.cgi (historical logs)
Additionally, a new web app is included – jsonquery.html & jsonquery.js. This is a small UI for crafting GET requests, it can be used to trial specific parameters for GET requests, or to just explore the api. It is also the easiest way to get acquainted with the new CGIs.

New to Nagios XI 2014, is the ability to generate reports based on service level agreement (SLA) statistics. In addition to the already included Availability Report, the SLA Report gives you the ability to prove, via already monitored hosts and services within your Nagios system, that you are meeting or exceeding those pesky up-time agreements.
As per traditional Nagios XI reporting capabilities, there are a wide variety of included time periods that will fit most use cases, as well as the ability to generate reports based on custom time periods. Reports can also be filtered by Host, Hostgroup, and Servicegroup for maximum flexibility when only specific hosts and services need to have reports generated. The final important aspect when generating a report is the modifiable SLA Target value. This allows you up to 5 points of precision when generating reports and can fully calculate the five 9s(99.999%) used in so many cases.
