Objective

A log is an event that occurred on a computer system (server, computer, application, website, database, computer network, etc.). For example, a log can record and contain one or more of the following elements:

• The timestamp (date, hour, minute, second, etc.) of the event.
• The nature of the event (connection, disconnection, error, download, upload, alert, etc.).
• Additional information about the event (page or file viewed, application launched, remote server called, name of a file uploaded or downloaded, etc.).
• The origin of the event (user ID, source IP address, source program, etc.).
• The state of the system where the event takes place (available resources, remaining memory, CPU usage, etc.).

Most of the time, logs are generated directly by the computer systems where the events occur. They are stored and archived in text files, also called log files.

As a result, log files allow you to:

• Analyse the behaviour of the computer system generating the logs.
• Identify errors that have occurred on the computer system.
• Resolve errors encountered on the computer system.
• Optimise the performance of the computer system.

Your web hosting plan therefore generates its own logs.

In some situations, you may need to view or retrieve the logs:

• of your web hosting plan;
• for one of the websites or applications hosted on your web hosting plan.

Find out how to enable, view and manage the logs of the websites or applications hosted on your web hosting plan.

Viewing the real-time logs of your web hosting plan

Subscribing the logs of your web hosting plan to Logs Data Platform

Logs Data Platform is a platform for managing your logs. It can be useful if you have a very large infrastructure or if your services generate a great deal of logs. Indeed, this platform is designed to make aggregating and managing logs easier.

It works by retrieving the logs generated by your infrastructure, websites or applications, in order to, for example:

• store them;
• display them in real-time dashboards;
• let users run complex queries;
• filter them by date, application, type or content;

For more details on Logs Data Platform, see our introduction to Logs Data Platform guide.

Since web hosting plans can be used with many services (databases, etc.), you can subscribe them to Logs Data Platform via a data stream, in addition to the real-time logs already available.

With a Logs Data Platform account, you get 1 GB of log retention free of charge. To benefit from it, you must activate your Logs Data Platform account free of charge and subscribe your web hosting plan to a data stream.

To subscribe your web hosting plan to a data stream on Logs Data Platform, 2 cases are possible:

• If you have several Logs Data Platform solutions in your OVHcloud Control Panel, select, from the drop-down list located just above the button labelled Create a data stream, the reference of the Logs Data Platform you want to subscribe with.

If the relevant stream already exists, it appears as a row in the table at the bottom of the page. In this specific case, to subscribe your web hosting plan to this existing stream, simply click the Subscribe button located to the right of the row corresponding to the relevant stream.

After a few seconds, and if you stay on the same page, a message will confirm that the subscription has been created.

If needed, see our “Introduction to Logs Data Platform” and “Getting started with Logs Data Platform” guides for these steps.

Once the forms have been filled in, click the Save button.

You will then be redirected to the Data stream tab of your Logs Data Platform solution.

All that remains is to subscribe your web hosting plan to your newly created stream on your Logs Data Platform solution.

To do this, go back to the Logs tab of your web hosting plan, as explained previously, to subscribe to this new data stream, then this time follow Case no. 1 described above.
