Performance Metrics of Tor Relay Server from Nyx
Nyx, a terminal-based monitoring tool, provides an excellent overview of the Tor relay’s real-time activity and performance. Compared to other tools, Nyx stands out for its intuitive interface, real-time data visualization, and ability to display detailed metrics like bandwidth usage, connection statistics, and relay flags, making it particularly suitable for Tor relay monitoring. Here are some key metrics displayed in the first image:
1. Bandwidth Utilization
- Inbound and Outbound Traffic: The bandwidth graph shows consistent data transfer rates, averaging around 7.0 MB/sec. This highlights the relay’s active participation in handling traffic within the Tor network.
- Total Bandwidth Usage: The relay has processed over 35 GB in- and over 33 GB outbound traffic during the session, demonstrating its significant contribution to supporting anonymous communication. For context, typical Tor relays might handle anywhere from 10 GB to 50 GB of traffic per day depending on their bandwidth allocation and uptime, placing this relay’s performance well within the expected range for a high-performing node.
2. Relay Flags
- The server holds flags like
Fast,Guard,Running, andStable, which signify:- Fast: The relay is capable of handling high bandwidth.
- Guard: It is used as an entry point to the network due to its reliability.
- Running and Stable: Indicate consistent uptime and dependable performance.
3. Events and Bootstrap Progress
- The relay has successfully bootstrapped and established Tor circuits, which is crucial for maintaining secure connections. Messages like “Bootstrap 85%: Connecting to a relay to build circuits” confirm that the relay is fully operational.
Connection Insights on Tor Relay Server
The second image from Nyx focuses on connection statistics, providing deeper insights into traffic handling and relay efficiency. These statistics are crucial because they help evaluate the health of the relay by showing how well it manages incoming and outgoing connections, as well as the number of active circuits facilitating traffic flow. By analyzing this data, administrators can ensure the relay is running optimally and contributing effectively to the Tor network.
1. Total Connections
- Inbound Connections: 4602 connections indicate that the server is actively receiving data from other Tor relays or clients.
- Outbound Connections: 3757 connections show its role in forwarding traffic within the network.
- Circuits: Six active circuits are facilitating anonymous communication across the network.
2. Connection Details
- The detailed table shows anonymized IP addresses and connection statuses, providing insights into how data is relayed securely without revealing user identities.
The TP-Link EAP670 delivers ultra-fast Wi-Fi 6 speeds up to 5400 Mbps, seamless roaming, and centralized management. Perfect for high-performance networks in Homelabs or offices.
System Resource Utilization with htop
The third image shows the server’s resource usage through htop, a system monitoring tool that helps identify resource bottlenecks and optimize performance. For example, if CPU usage spikes significantly or memory allocation exceeds expected thresholds, administrators can decide to limit bandwidth, adjust the relay’s workload, or upgrade the VPS resources to ensure consistent performance. Let’s analyze its significance:
1. CPU and Memory Usage
- CPU Load: The Tor processes collectively consume around 40% of the CPU, showcasing efficient usage given the high number of active connections and bandwidth.
- Memory Usage: Approximately 397 MB of memory usage is observed, leaving ample room for other processes on the IONOS 1€ VPS, which provides 1 GB of RAM.
2. Tor Processes
- Three primary
debian-torprocesses are managing the Tor relay operations, indicating optimal load distribution and multitasking. - Other system processes, like
systemdandcron, run seamlessly alongside the Tor relay without performance degradation.
Why the IONOS 1€ VPS is Perfect for a Tor Relay
Our Tor relay server runs on the affordable IONOS 1€ VPS. Here’s why this setup works so well:
- Cost-Effective: The 1€/month VPS provides an economical option for contributing to online privacy without significant investment. However, low-cost VPS solutions may have limitations, such as restricted bandwidth or lower computational resources, which might affect performance during peak usage. Despite this, they remain highly effective for smaller-scale Tor relays.
- Sufficient Resources: With 1 GB RAM and a stable 1 Gbps network connection, the VPS meets all the requirements for running a high-performing Tor relay.
- Reliable Performance: The VPS’s consistent uptime ensures that the relay remains functional, earning important flags like
StableandRunningwithin the Tor network. - Ease of Setup: Pairing this VPS with our setup guide makes the process seamless for new users.
