[H2] FAQ

Can I use NCPA with Nagios Core?
Of course! While we built NCPA with Nagios XI in mind (due to some awesome integration via the NCPA config wizard) but the agent can send passive checks to Nagios Core or use our check_ncpa.py plugin to run active checks from Nagios Core.
Why did you choose Python?
Python is a very flexible language. It can be used on most operating systems and when we wanted to be able to run our binaries without any requirements, it's modular layout pairs perfectly with it's small footprint. Python also has a large community and is a very popular language.
I read your license, can I fork the NCPA GitHub repo to make a pull request?
While the Nagios Open Source Software License may seem rather restricting, we want to work together by collaborating with the community. You may fork the NCPA GitHub repository to contribute to the development of NCPA. However, you cannot fork the code to create a competing product.
Where should I report bugs?
The quickest way to get in contact with the developers is by creating an issue on the project's GitHub issues page. Try to be as descriptive as possible so we can reproduce the bug and fix it.
It's been a while since the last update, is the project still being developed?
Yes, it is. You may have noticed that NCPA has periods of active daily development and periods where there may be hardly any development from the Nagios developers. This is a true open source project for the Nagios developers and we don't normally work on it during the business work day. We are normally busy making cool new features and squashing bugs in the variety of enterprise monitoring products that Nagios Enterprises offers. This means 95% of all NCPA development is done on the developer's own time. With that said, we will try to respond to any issues on GitHub as quickly as possible, so don't be shy.
[H2] Project
The origins of NCPA can be traced back to the 2012 Nagios World Conference, where a network admin stated, “I have no idea why agents are so difficult”. After reflecting on the statement, we had no answer. The idea for NCPA to be a single monitoring agent that was secure, simple, and easy to manage was formed.In 2014, the first version of NCPA was released with the basic features that are core to the project such as the cross-platform API.
Today, NCPA has come a long way from the initial idea back in 2014. It includes countless extra features with many more under development.

[H2] How to Migrate
Migrating from Nagios Core to  XI involves a few key steps to get you up and running. We’ve outlined the main steps here to help guide you through the process.For a deeper dive into the migration, check out our Roadmap for Making the Upgrade From Core to XI , and if you need more detailed instructions, be sure to visit our full guide to Migrating From Core to XI.
For advanced setups, like distributed monitoring environments, additional configuration may be needed. Please refer to our documentation for more details.
[IMG: info]
You can now automatically migrate Nagios Core data to Nagios XI. See Automatic Nagios Core Migration to Nagios XI for more information.
[H3] 1. Deploy a New Nagios XI instance
In order to migrate from Nagios Core to Nagios XI, you should deploy a clean installation of Nagios XI to a different physical server or virtual machine than what is used for your existing Nagios Core installation. This allows you to migrate settings to XI and test the new monitoring setup before decommissioning your old server.
[H3] 2. Upload Plugins and Scripts to Nagios XI
To use your custom plugins and scripts in Nagios XI, you’ll need to upload them to the /usr/local/nagios/libexec directory. You can do this easily through the XI web interface under the Admin menu. For more details, check out the Managing Plugins in Nagios XI guide. Custom event handlers or notification scripts should also be placed in the same directory or in a subfolder like /eventhandlers.
[H3] 3. Import Nagios Core Configuration Files to Nagios XI
When migrating to Nagios XI, you can bring over your Nagios Core configuration files, including hosts, services, commands, and more. You have two options: manually maintain the configuration files or import them into the Core Config Manager (CCM) database. You can also mix and match—starting with manual files and importing later, or importing some files while keeping others manually maintained.
[H4] Option 1: Manually Maintained Config Files
Manually-maintained configuration files should be stored in the /usr/local/nagios/etc/static directory on your Nagios XI server. If you prefer to maintain your configuration files manually instead of importing them into the web configuration database, refer to the related documentation for more details.
[H4] Option 2: Importing Config Files
[H4] Prepare Import
Before importing, use the Nagios Config Import Prep Tool.
[H4] Import Configuration Files
Navigate to the Core Config Manager (CCM), then go to Tools > Import Config Files. Import in the correct order, ensuring all required objects exist.
[H4] Validate and Adjust
After importing, validate your configuration files before applying changes.
[H4] Apply Configuration
Once verified, use the Apply Configuration option to restart Nagios Core with the new setup.
[H3] 4. Add User Accounts To The Nagios XI Server
After migrating your Nagios Core configurations to Nagios XI, you’ll need to add user accounts for access to the XI web interface. You can create new users through Admin > Users > Manage Users. Nagios XI allows users to manage their notification preferences, but if you have custom or advanced schedules from Nagios Core, you can retain those settings. For more details, check out the Understanding Nagios XI Users and Contacts documentation.
[H4] Option 1: Controlling Contact Preferences With Nagios XI
Let users manage notifications in XI by matching the username to the Nagios Core contact and selecting “Create as Monitoring Contact.”
[H4] Option 2: Controlling Contact Preferences Outside Nagios XI
Retain advanced notification settings by matching the username but unchecking the “Create as Monitoring Contact” option to prevent XI from overwriting Core settings.
[H3] 5. Test the XI Server
Make sure you test your new XI server to ensure it is operating effectively. Items you should check include:
• Host and service checks are operating properly and returning the expected results
• Notifications are functioning properly
[H3] 6. De-commission the old Nagios Core Server
Once you have migrated the plugins, scripts, and configuration files from your old Nagios Core installation and have successfully verified Nagios XI’s operation, you may decommission the old Nagios Core server. Before doing so, it is recommended that you retain a backup of the server and its Nagios Core configuration in case you need them in the future.

We are normally busy making cool new features and squashing bugs in the variety of enterprise monitoring products that Nagios Enterprises offers.

Your Diagnosis

Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.

Information Density 0 / 30
Read the Narrative & headings: do hard facts (prices, dates, numbers) outweigh fluff power-words?
Semantic Coherence 0 / 20
Compare the homepage promise against the sub-page reality. Do they hold the same line?
Trust & Proof 0 / 20
Weigh review mentions against actual external proof links. Claims without verification = theatre.
Commodity Fingerprint 0 / 15
Check headings & narrative against the industry clichés in the setup above.
Identity & Authority 0 / 15
Inspect the schema: is there real Organization/Person identity with sameAs links, or gaps?
Your predicted BS score 0 / 100
💡 Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)

These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.

Information Density

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Semantic Alignment

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Trust & Proof

Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.

Commodity Fingerprint

Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.

Identity & Authority

Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.

Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

1. Link the review counts directly to third-party verification pages (G2, Capterra) to increase the proof_links_count. 2. Provide a verified download counter or third-party report to substantiate the ‘millions of times’ claim. 3. Add Person schema for lead maintainers or founders to ground the ‘Global Community’ claim in verifiable human authority. 4. Standardize the review display to include dates to prevent aging evidence from eroding credibility.

The site is an exact match for the Software and IT Infrastructure Monitoring category. The content is heavily focused on technical deliverables, system agents, and network protocols consistent with an established monitoring solution.

“The score of 18 is primarily driven by the trust_and_proof pillar, specifically the discrepancy between claimed review counts and available verification links. Minor points were awarded for industry cliches like 'Enterprise-grade,' though these are largely offset by the site's high information density and technical specificity.”
