Suimon is a free, open-source command line tool for people who run nodes or validators on the SUI network and want a clear view of how they are performing. It is aimed at node operators, validator teams and developers who prefer watching system states in a terminal rather than in a browser-based dashboard.
The tool is built to display detailed dashboards that show the health and performance of your nodes and validators, along with important system states and events as they happen. If you are responsible for keeping SUI infrastructure online, Suimon gives you a single place to check whether things look normal, without assembling your own scripts from scratch.
What Is Suimon and Who Is It For?
Suimon is a monitoring utility rather than a wallet or trading tool. It does not hold funds, sign transactions or connect to exchanges. Its job is to observe the machines that take part in the SUI network and report on them.
The most natural users are validator operators and infrastructure engineers who keep one or more SUI nodes running around the clock. A small team running a single validator and a larger operation with several machines can both benefit, because the same dashboards scale from one host to many.
Developers who build services on top of SUI may also find it useful, especially when they need to confirm that the nodes their application depends on are healthy.
Why Monitoring Matters for Node Operators
Blockchain infrastructure rarely fails loudly. A node can fall a few blocks behind, a disk can fill up slowly, or a process can stop responding while still appearing to run. Without regular checks, these problems often go unnoticed until someone asks why a service is slow.
A dedicated monitoring tool reduces that risk by making the normal state visible. When you know what healthy looks like on your own machines, a deviation stands out quickly. This is the core value Suimon offers: a consistent, readable picture of your setup rather than a collection of raw logs.
For teams, shared dashboards also help during handovers. A new operator can look at the same views an experienced colleague uses and learn what to watch.
How Suimon Fits Into a Typical SUI Setup
A common arrangement places one or more nodes on dedicated servers, with monitoring running either on the same host or on a separate machine that can reach the metric endpoints. Suimon is designed to sit alongside that infrastructure and query the endpoints it has been configured to use.
Because the configuration allows optional fields, you can keep the initial setup minimal and add settings later, such as additional targets or display preferences. This makes it practical to start monitoring quickly and refine the configuration once you know which numbers matter most to you.
The tool's focus on the SUI network means you do not have to adapt a general-purpose monitoring stack to understand SUI-specific states and events.

How to install Suimon on Windows
- 1
Get the program from the official source
Download only from the official website or the project's GitHub repository at https://github.com/bartosian/suimon. Use the releases page to find the current version rather than third-party download sites. Avoid mirrors you do not recognize.
- 2
Check the file before running it
Compare the SHA-256 checksum of the downloaded file with the value published by the project, if one is provided. If the release is signed, verify the signature. A mismatch means the file may have been altered, and you should not run it.
- 3
Install the program
Run the Windows build or installer you downloaded. If you receive a plain executable, place it in a folder of your choice and add that folder to your PATH so you can start Suimon from any terminal window.
- 4
Confirm the installation
Open a terminal, such as Windows Terminal or PowerShell, and run the program's version command. A version number in the output confirms that the file is in place and runs correctly.
-
Prepare the configuration
Create or edit the configuration file so it points to the metric endpoints of your nodes and validators. Start with the required endpoints and add optional settings later.
System requirements
- Windows with a terminal application such as Windows Terminal or PowerShell
- Network access to the metric endpoints of the SUI nodes or validators you want to monitor
- A configuration file that points to those endpoints
How to use Suimon
Once Suimon is installed and configured, using it is a matter of starting the dashboard and reading what it shows. The steps below describe a typical first session.
- Open a terminal window and navigate to the folder where Suimon is located, or make sure it is available on your PATH.
- Point the configuration file at the metric endpoints of your nodes and validators, and save the file.
- Start Suimon from the terminal so the dashboards begin loading data.
- Check that the health views show your machines and that the values look reasonable for your setup.
- Review the performance figures to establish a baseline of normal behavior for each node.
- Watch the system state and event displays for a few minutes to see what routine activity looks like.
- Adjust optional configuration fields, such as additional targets, once the basic setup works.
- Keep the session running in a dedicated terminal or on a monitoring host so you can check it regularly.
Pros & cons
- Free and open source under the MIT license
- Presents node and validator health in clear terminal dashboards
- Tracks real-time system states and events
- Minimal required configuration, with optional fields you can add later
- Focused specifically on the SUI network
- Suitable for servers managed over SSH without a graphical desktop
- Command line only, so it is less approachable for users who prefer graphical interfaces
- Requires some familiarity with terminals and configuration files
- Monitors SUI infrastructure only, not other blockchains
- Documentation is limited compared with large commercial monitoring suites
- The latest code update dates from October 2024, so check the project page for ongoing maintenance before relying on it heavily
Is Suimon safe?
Suimon is open source, which means its code can be reviewed on GitHub. Download it only from the official GitHub repository or the project's official channels, and verify the SHA-256 checksum or signature of the file before running it. Never download monitoring tools from unofficial sites, as they may be bundled with malware.
Because Suimon reads metrics from your nodes, make sure the endpoints it queries are secured and not exposed to the public internet without protection. Keep the program and your operating system updated, and review the latest code activity on the repository, since the most recent code update was in October 2024.
Suimon does not ask for seed phrases or private keys. Treat any prompt for that kind of information as a red flag, whatever the source.
- Official source only. Download from github.com/bartosian/suimon. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Suimon differs from general-purpose blockchain explorers and analytics platforms in that it is an operator tool rather than a public data service. Explorers help you look up transactions and accounts across the network, while Suimon focuses on the health of machines you run yourself.
Compared with tools built for other chains, Suimon is specialized for SUI. Projects such as Chainhook, which indexes Stacks and Bitcoin data, or Cshtop, which visualizes Cosmos blocks in the terminal, serve different networks and different needs. If your infrastructure is on SUI, Suimon is the more directly relevant choice.
For readers who want to build their own data pipelines or analytics, tools such as Bitcoin Database Generator or Analytics Ecosystem Data may be more useful. Suimon is best understood as a focused monitoring dashboard for SUI nodes and validators.

Verdict
Suimon is a focused, free and open-source tool for anyone who runs SUI nodes or validators and wants a clear terminal view of their health, performance and events. It is most valuable to operators and infrastructure engineers who are comfortable with the command line. If you need a broad, multi-chain or graphical analytics platform, look elsewhere. If your work centers on keeping SUI infrastructure reliable, Suimon is a sensible option to evaluate, with the caveat that you should review the project's recent activity before relying on it for critical operations.
