Cacti Review: Pros, Cons, Features and Pricing

Q: How does Cacti handle data security and compliance?

Cacti is an open-source tool, so data security largely depends on how you configure and manage it. You need to ensure proper access controls and regular updates to maintain security. While Cacti doesn’t come with built-in compliance features, you can implement security measures to meet your organization's requirements. Consider consulting with your IT team to ensure Cacti aligns with your compliance standards.

Q: Is Cacti suitable for large-scale network monitoring?

Cacti can handle large-scale networks, but it may require significant customization and resources. Your team should be prepared to manage and optimize its performance for extensive monitoring. Larger organizations might need additional plugins or tools to supplement Cacti’s capabilities. It’s important to assess your network’s specific needs and resources before implementation.

Q: What kind of technical expertise is needed to use Cacti effectively?

To use Cacti effectively, your team should have a solid understanding of network concepts and Linux systems. Familiarity with SNMP and graphing tools is also beneficial. While Cacti provides documentation, it may not be enough for beginners. Having at least one team member with technical expertise can make the setup and management process smoother.

Q: Can Cacti be customized to fit specific monitoring needs?

Yes, Cacti is highly customizable, allowing you to tailor it to your specific monitoring needs. You can create custom graphs and templates to visualize the data most relevant to your network. This flexibility is a key advantage for organizations with unique monitoring requirements. However, customization may require technical expertise to implement effectively.

Q: How reliable is Cacti for real-time network monitoring?

Cacti is reliable for network monitoring but may not offer the real-time data speed of some other solutions. It’s more suited for tracking historical data and performance trends. If real-time monitoring is a priority, you may need additional tools to complement Cacti. Evaluate your real-time monitoring needs before deciding if Cacti is the right fit.

Q: What are the common challenges faced during Cacti implementation?

Common challenges during Cacti implementation include initial setup and configuration difficulties. Your team might find the documentation lacking in some areas, requiring additional research or expertise. Customizing Cacti to suit your needs can also be time-consuming. It’s beneficial to plan for these challenges and allocate resources accordingly.

Q: Does Cacti support distributed monitoring?

Cacti can support distributed monitoring with additional configuration and plugins. You’ll need to set up a distributed polling environment to monitor networks across different locations. This setup can be complex, so ensure your team has the necessary technical skills. Distributed monitoring can enhance Cacti’s capabilities for larger, multi-site operations.

Q: How does Cacti's community support compare to professional support services?

Cacti relies heavily on community support through forums and user-contributed content. While this can be helpful, it may not provide the immediate assistance found in professional support services. Your team should be prepared to search for solutions and collaborate with the community. For critical issues, having internal expertise can be invaluable.

Cacti is an open-source network monitoring software built around RRDtool for polling network devices and generating detailed performance graphs. It's a strong fit for IT teams that need granular visibility into network traffic, bandwidth, and device health without a licensing budget. If you've looked at PRTG Network Monitor but want to avoid per-sensor pricing, Cacti gives you flexible, customizable monitoring at no cost—though it does require more hands-on configuration to get up and running.

Our Review Methodology

How We Test & Score Tools

We’ve spent years building, refining, and improving our software testing and scoring system. The rubric is designed to capture the nuances of software selection and what makes a tool effective, focusing on critical aspects of the decision-making process.

Below, you can see exactly how our testing and scoring works across seven criteria. It allows us to provide an unbiased evaluation of the software based on core functionality, standout features, ease of use, onboarding, customer support, integrations, customer reviews, and value for money.

Core Functionality (25% of final scoring)

The starting point of our evaluation is always the core functionality of the tool. Does it have the basic features and functions that a user would expect to see? Are any of those core features locked to higher-tiered pricing plans? At its core, we expect a tool to stand up against the baseline capabilities of its competitors.

Standout Features (25% of final scoring)

Next, we evaluate uncommon standout features that go above and beyond the core functionality typically found in tools of its kind. A high score reflects specialized or unique features that make the product faster, more efficient, or offer additional value to the user.

We also evaluate how easy it is to integrate with other tools typically found in the tech stack to expand the functionality and utility of the software. Tools offering plentiful native integrations, 3rd party connections, and API access to build custom integrations score best.

Ease of Use (10% of final scoring)

We consider how quick and easy it is to execute the tasks defined in the core functionality using the tool. High scoring software is well designed, intuitive to use, offers mobile apps, provides templates, and makes relatively complex tasks seem simple.

Onboarding (10% of final scoring)

We know how important rapid team adoption is for a new platform, so we evaluate how easy it is to learn and use a tool with minimal training. We evaluate how quickly a team member can get set up and start using the tool with no experience. High scoring solutions indicate little or no support is required.

Customer Support (10% of final scoring)

We review how quick and easy it is to get unstuck and find help by phone, live chat, or knowledge base. Tools and companies that provide real-time support score best, while chatbots score worst.

Customer Reviews (10% of final scoring)

Beyond our own testing and evaluation, we consider the net promoter score from current and past customers. We review their likelihood, given the option, to choose the tool again for the core functionality. A high scoring software reflects a high net promoter score from current or past customers.

Value for Money (10% of final scoring)

Lastly, in consideration of all the other criteria, we review the average price of entry level plans against the core features and consider the value of the other evaluation criteria. Software that delivers more, for less, will score higher.

Open-Source Flexibility

Being open-source, Cacti offers your team the ability to modify and extend the software to suit unique requirements.

Ease of Use

Cacti isn’t the most user-friendly network monitoring tool, especially if your team lacks technical expertise. Its setup and configuration can be tricky, requiring a good grasp of network concepts. The interface feels a bit outdated, which might slow down your workflow. However, once you’ve navigated the initial learning curve, Cacti’s customization and visualization capabilities provide great value for those willing to invest the time.

Onboarding

Onboarding with Cacti can be a bit challenging, especially if your team isn’t familiar with network monitoring setups. The documentation is helpful but may not be enough for those new to the field. While community forums offer support, the lack of structured onboarding resources might slow down your time to value. Your team should be prepared for a learning curve and possibly seek additional resources or expertise to get up and running effectively.

Customer Support

Cacti's customer support relies heavily on community forums and user-contributed documentation, which can be a mixed bag. While you might find helpful advice from experienced users, the lack of dedicated support staff can be frustrating if you need quick answers. Your team may encounter delays in resolving issues, so having someone with technical expertise in-house is beneficial. Overall, the support is decent but may not meet the needs of users seeking immediate, professional assistance.

Integrations

Cacti can integrate with New Relic, Datadog, and Drupal. Cacti does not have a native REST API, but it allows data extraction directly from its database tables.

Value for Money

Cacti is available for free through the GNU General Public License .
