To determine whether the traffic of the Singapore cloud server exceeds the standard, it is necessary to monitor the network traffic of the Singapore cloud server. Ensure that when monitoring cloud server traffic in Singapore, the distinction between inbound and outbound traffic and the direction of traffic is taken into account, either by monitoring the cloud service provider's console or using monitoring tools for real-time traffic monitoring. The following are some common steps to determine whether the cloud server traffic is exceeding the limit and the solution:

Check whether the cloud server traffic exceeds the limit.

Cloud service provider console

Log in to the management console of the cloud service provider to view the network usage of the cloud server. Usually, there are monitoring and reporting functions in the console to see incoming and outgoing traffic.

Monitoring tool

Use third-party monitoring tools, which often provide more detailed traffic statistics and alarm features. Some cloud service providers also offer apis to integrate real-time traffic information through monitoring tools. Some commonly used tools include:

iftop is a terminal based real-time traffic monitoring tool that can be used to display real-time traffic across network connections.

nload provides a graphical real-time traffic monitoring interface, which can display the real-time inbound and outbound traffic of network interfaces.

vnStat is a command line based traffic monitoring tool that provides detailed network traffic statistics, including daily, monthly, and annual usage.

Alerts and notifications from cloud service providers

Configure your cloud service provider's alarm and notification capabilities so you can receive notifications when network traffic exceeds a set threshold so you can take timely action.

Monitoring system

Use a professional monitoring system, such as Prometheus, Grafana, etc., to set up a traffic monitoring dashboard to track your server's traffic in real time. These tools often provide more advanced statistical and alarm capabilities.

Log file

View network log files of the server, such as those in the /var/log directory, to obtain information about network traffic. Pay special attention to log files related to networks and traffic.

Cloud service provider billing

Periodically review the billing and usage reports provided by the cloud service provider, which typically include the server's network traffic usage. By viewing the historical billing, you can understand the trend of server traffic.

Solutions to cloud server traffic limit:

Upgrade bandwidth

If the cloud server traffic approaches or exceeds the limit, upgrade the bandwidth. Cloud service providers often allow bandwidth to be dynamically adjusted at run time.

Optimize resources

Check whether unnecessary services or resources occupy bandwidth and optimize resource configuration to reduce traffic consumption. This may include optimizing databases, caching configurations, or using a content delivery network (CDN) to ease traffic pressure.

Use a CDN

Using a CDN can distribute static content to edge nodes closer to users, reducing the burden on cloud servers and reducing server traffic pressure.

Compressed content

Compress data during transmission to reduce the amount of data transferred. This is very effective for reducing the transfer traffic of large files.

Limit non-essential traffic

Control unnecessary traffic on the server. For example, configure firewall rules and disable unnecessary services or ports to reduce unnecessary traffic.

Set traffic alerts

Set traffic alerts in the cloud service provider's console or monitoring tool to receive timely notifications and take appropriate action when traffic approaches a set threshold.

Investigate abnormal traffic

If abnormal traffic occurs, it may be due to malicious attacks, DDoS attacks, or application vulnerabilities. In this case, take timely security measures and analyze the source of the attack to prevent it as early as possible.

Periodically monitoring traffic and taking appropriate measures to avoid traffic overload is an important step to ensure the normal operation of cloud servers. Depending on the specific situation, there are many ways to deal with the traffic overflow problem.
