9 Nagios XI Wizards to Monitor Your Website

1. Defacement
To protect against web defacement attacks, using a Defacement Wizard can save you significantly from damages and loss of private information. This website defacement monitoring wizard uses the regular expression check to find a specific string that you do not want to appear on your website. You receive a critical response when the check finds one or more of the strings it was instructed to search for on the website. These strings can be organically created from lists of words, loading a CSV file, or selecting from categories of terms (gambling, profanity, pharmaceutical, etc.).

Our Defacement Wizard step-by-step guide can help you get started today.

2. URL Changes
Because URLs are often a long string of numbers and letters, information within that URL can be changed and go unnoticed. With the Website URL Wizard, any important copy within the URL can be entered and monitored in the “Content String to Expect” box. Now you can passively check for changes in the string and be notified when something happens.

The URL wizard is designed to accept any URL, even the adaptive or customized details. It’ll tag that and check for that exact URL. You can check for content inside the URL or an expected part of the string.

3. Domain Name System (DNS) Change
When visiting a website, the DNS identifies computers, services, and resources that align with the internet or an IP network such as HTTP. Through monitoring DNS changes you to stay on top of changes that might be a result of hijacking and redirections.

Once a website is implanted, Nagios reaches out and finds the IP address that it’s assigned. This check looks for compromised domain registrations, control, and other risks. You can adjust these checks to whatever frequency you prefer, and receive custom notifications to your specific standards.

4. Secure Sockets Layer (SSL) Certificate Expiration
Maintaining up to date Secure Sockets Layer Certifications secures your organization’s reputation and keeps users safe from hackers accessing private data. Nagios provides SSL Certificate monitoring to ensure that expired certificates don’t negatively impact your organization’s websites, applications and security. Nagios can generate alerts when SSL certificates near their expiration date so IT admins have time to renew before problems occur.

Gain awareness to when files and folders are modified, updated, or deleted with the Nagios Folder Watch Wizard.

6. User Count
Monitoring user count can help your team establish peak hours and pages being visited. This information leads to better planning and scheduling of downtime.

The Nagios XI NCPA Wizard will get you started tracking user count.

7. Process Count
A server should continuously be running a certain number of applications and processes, but this number can vary from one organization to another. Fortunately, process count can be leveraged within Nagios so that you know if the number of items running is consistent and aligned with your infrastructure expectations. This passive check is a great tool to verify the overall health of your servers and provide concrete data to support purchase decisions or needs.

Leverage Process Checks to better understand your infrastructure.

8. Bandwidth Usage
Being able to calculate an expected usage of bandwidth can help indicate if there is an issue. Measure individual ports in a router, determine if they’re consuming more or less than anticipated, or verify if they’re plugged in. Monitoring your bandwidth usage leads to faster detection of network outages and protocol failures.
