How to use PHP X-Ray

X-Ray is a tool designed to monitor website performance and detect performance issues.

X-Ray can collect and display information about slow scripts, external queries and website database queries.

To switch to X-Ray, log in to the DirectAdmin hosting control panel and click the X-Ray tab.

X-Ray provides a manual option for monitoring requests to the site:

A manual trace task is a task that can be created for a specific URL to collect queries. The task will finish either after the specified number of requests to the URL, or after a specified amount of time (two days at most).

It is also possible to export the report in PDF format.

The Trace Tasks tab contains a list of all tracing tasks created manually.

  1. Click the Start tracing button to create a new task.
  2. In the pop-up window that opens, specify the URL of the website to track.
  3. Press the Run button.
  4. Traceroute will work in default mode, tracing the first 20 requests to the specified URL.

Default settings:

The URL must be a valid URL for the domain that exists on the current server.

Advanced settings allow you to set the IP address and tracking parameters: by time or by number of requests.

Advanced settings:

  • Client IP: This is the IPv4 address of the traceroute client.

For example, if you have a working website that handles requests from different IP addresses and you don’t want to add those requests to the tracking task. Thus, you can specify a specific IP address and X-Ray will analyze requests only from that specific IP address.

  • Time period recording: how long X-Ray collects requests (maximum 2 days)
  • Queries: the number of queries that X-Ray will collect.

Once created, the task will appear in the task list.

Task Statuses:

  • Running – tracing is running.
  • Stopped – tracing is stopped manually.
  • On hold – this URL already exists in the list. Task processing will not start automatically. You have to run it manually.
  • Completed – the period of time completed or the number of requests reached.

Collected information on the task:

Press the eye button to view the collected information.

Slow requests will be highlighted.

  • Total – shows how many queries were collected according to the task.
  • Pending – shows how many of the collected queries are not yet displayed in the table.
  • Throttled – displays the number of requests that exceeded LVE limits.
  • Slow – displays the number of requests longer than one second.

If slow requests were not detected during the trace, the following is displayed. Here you can also see all the requests.

X-Ray collects the following data for each query:

  • Top issues – the slowest query items
  • Software modules/plugins – modules and plugins by runtime (only for WordPress)
  • Database queries – database queries by execution time
  • External requests – requests to external resources by execution time
  • Other system functions – system functions by execution time

Software modules/plugins – modules and plugins

How can I use PHP X-ray to speed up my WordPress site and find the cause of slowness?

  • Specify the URL of the slow site.
  • Visit a slow site and do something like leave a comment to make a POST request. This will allow PHP X-Ray to gather information about site performance.
  • Go back to the tracing task. You will see the slowest queries at the top of the list.
  • Take a look at the information page that shows performance problems. For example, if one of the WordPress plugins uses a lot of resources, you will see this in the table.
  • Disable the plugin through the WordPress admin interface.
  • Go to the site again and make a few more requests. The site should load faster than before. There should be no performance issues on the details page.
