What domain activity looks like in a log file

A log file is a record that your web server keeps automatically. It tracks every request that comes to your domain — who visited, when they visited, what page they looked at, and whether the request succeeded or failed. When you check domains in a log, you are reading these records to see traffic patterns, errors, or suspicious activity tied to your domain name.

Log files live on your hosting account, usually in a folder called logs, log, or sometimes public_html/logs. The exact location depends on your hosting provider. Most providers let you download logs through a control panel like cPanel, Plesk, or a custom dashboard. Some providers also let you view logs directly in the browser without downloading.

Each line in a log file represents one request. A typical entry shows the visitor's IP address, the date and time, the page they requested, the HTTP status code (like 200 for success or 404 for not found), and how many bytes of data were sent. Reading a log means scanning these lines to find patterns — like a spike in traffic, repeated 404 errors, or requests from an unfamiliar IP address.

Key Takeaways

  • Log files are stored on your hosting account and track every request to your domain, including the visitor's IP, timestamp, page requested, and response status.
  • You can download logs through your hosting control panel (cPanel, Plesk, or your provider's dashboard) or view them directly in the browser if your provider offers that option.
  • HTTP status codes in logs tell you what happened: 200 means success, 404 means page not found, 500 means server error, and 403 means access denied.
  • Log files grow quickly and can be large; most hosting providers keep logs for 7 to 30 days before deleting old ones.
  • Text editors, command-line tools like grep, or online log analyzers can help you search logs for specific domains, IP addresses, or error patterns.

Where to find logs on your hosting account

The first step is logging into your hosting control panel. If you use cPanel, look for a section called "Logs" or "Raw Access Logs" — this is usually under "Metrics" or "Files". Click it, and you will see a list of log files, often organized by domain. Each domain typically has its own access log and error log. The access log shows all traffic; the error log shows only problems.

If your host uses Plesk, go to "Domains", select your domain, then look for "Logs" in the left menu. You will see options to view or download access logs and error logs from there. Some hosts like Kinsta, WP Engine, or Flywheel use custom dashboards instead of cPanel or Plesk — in those cases, look for a "Logs" or "Analytics" section in your main dashboard, or check your host's documentation for the exact path.

Once you find the logs section, you can usually download the file directly to your computer or view it in the browser. Downloading is often faster if the log is large. Most hosting providers keep logs for 7 to 30 days; older logs are deleted automatically. If you need logs older than that, download them now and save them to your computer.

How to read the entries in a log file

A typical access log line looks like this:

192.0.2.1 - - [15/Jan/2025:14:32:18 +0000] "GET /about HTTP/1.1" 200 5432 "-" "Mozilla/5.0"

Breaking this down: 192.0.2.1 is the visitor's IP address. [15/Jan/2025:14:32:18 +0000] is the date and time of the request. GET /about is the request type and the page requested. HTTP/1.1 is the protocol version. 200 is the HTTP status code — 200 means the page loaded successfully. 5432 is the size of the response in bytes. The Mozilla/5.0 part is the browser or bot that made the request.

Common HTTP status codes you will see: 200 (success), 301 or 302 (redirect), 304 (not modified), 400 (bad request), 403 (forbidden), 404 (page not found), 500 (server error), 502 (bad gateway), 503 (service unavailable). A log full of 200s is normal. A spike in 404s might mean a page was deleted or moved. A spike in 500s suggests a server problem.

Error logs are simpler — they show only problems. An error log entry might say something like "PHP Fatal error: Call to undefined function" or "Connection timeout". Error logs help you spot code problems or server issues that visitors experienced.

Using tools to search and filter logs

If a log file is large, opening it in a text editor can be slow. Instead, use a search tool. On Mac or Linux, open a terminal and use the grep command to find specific entries. For example, grep "192.0.2.1" access.log shows all requests from that IP address. grep " 404 " access.log shows all 404 errors. grep "example.com" access.log shows all requests to that domain.

On Windows, you can use PowerShell with similar commands, or download a free tool like Notepad++ or Visual Studio Code, which both handle large files better than the built-in Notepad. Some hosting providers also offer built-in log analyzers in their control panel — these let you filter by date, status code, or domain without downloading the file.

For a more visual approach, online log analyzers like Goaccess or Awstats can turn a raw log file into charts and summaries. You upload the log file, and the tool shows you top pages, top IP addresses, traffic over time, and error breakdowns. These tools are free and run in your browser.

Checking for suspicious activity in logs

If you suspect a security problem or unusual traffic, logs can help you investigate. Look for patterns like repeated requests from the same IP address to pages that do not exist, requests with strange characters in the URL, or a sudden spike in traffic from one IP. Bots and attackers often make many requests in a short time, so a single IP with hundreds of requests in an hour is a red flag.

Check your error log for signs of hacking attempts — things like "SQL injection", "XSS", or repeated "403 Forbidden" errors can indicate someone trying to break in. If you see a spike in 500 errors, your site may have been compromised or is under a denial-of-service attack. In that case, contact your hosting provider immediately.

You can also use logs to check if a domain is actually receiving traffic. If a domain shows no requests in the access log over several days, either no one is visiting it, or the domain is not properly pointed to your hosting account. Check your domain's DNS settings to make sure it points to the right server.

Understanding log rotation and retention

Hosting providers do not keep logs forever. Most rotate logs daily or weekly, meaning old logs are compressed or deleted to save space. A typical setup keeps the current log plus 7 to 30 days of backups. After that, the logs are gone. If you need to check logs from months ago, you will not find them unless you downloaded them earlier.

Log rotation usually happens at midnight or at a set time each day. You might see files named access.log, access.log.1, access.log.2, and so on — the number indicates how old the log is. access.log is today's log, access.log.1 is yesterday's, and so on. If you need historical data, download logs regularly and store them on your computer.

Some hosting providers let you adjust retention settings — for example, keeping logs for 60 days instead of 30. Check your hosting control panel or contact support to see if this option is available. If you run a high-traffic site or need logs for compliance reasons, longer retention is worth requesting.

Checking multiple domains in one log

If you host multiple domains on the same account, they may share a single log file or have separate logs. Check your hosting control panel to see how logs are organized. Some providers create one log per domain; others create one log for the entire account and include the domain name in each entry.

If domains share a log, use grep or a log analyzer to filter by domain name. For example, grep "example.com" access.log shows only requests to example.com. This is useful if you want to check traffic for one domain without seeing noise from the others.

If each domain has its own log, navigate to the logs section and select the domain you want to check. The process is the same as checking a single domain — download or view the log, then search for patterns or errors.

Frequently Asked Questions

How far back can I check logs?

Most hosting providers keep logs for 7 to 30 days. After that, old logs are deleted automatically. If you need older logs, you must download them before they are deleted and save them to your computer. Check your hosting provider's documentation or contact support to find out their exact retention period.

What does a 404 error in logs mean?

A 404 error means the visitor requested a page that does not exist. This can happen if a page was deleted, moved, or the visitor typed the URL wrong. A few 404s are normal. Many 404s might mean a page you deleted was popular, or a bot is scanning for common vulnerabilities.

Can I see which country a visitor came from in the logs?

Logs show only the IP address, not the country. To find the country, use a free IP lookup tool like MaxMind GeoIP2 or IP2Location and enter the IP address from the log. These tools match IP addresses to geographic locations, though the results are approximate.

Why are my logs so large?

High-traffic sites generate large logs quickly — each request adds one line. Bots and crawlers also add entries. If a log is too large to open, download it and use grep or a log analyzer instead of a text editor. You can also ask your hosting provider to increase log retention or compression settings.

Do I need to check logs regularly?

For most sites, checking logs once a month is enough. If you suspect a security problem, check logs immediately. If you run a business-critical site or handle sensitive data, checking logs weekly or using automated monitoring tools is a better practice.
