Access Metrics

  1. Navigate to Metrics within the Live environment of your Site Dashboard.
  2. Toggle available date ranges by clicking Day, Week, or Month: Charts for pages served and visits within the Metrics tool of the Site Dashboard

Available Metrics

Pantheon tracks two traffic metrics which relate to site plan levels: Visits and Pages Served. These are available in the Site Dashboard, and are refreshed daily.

The data comes directly from our Global CDN, which tracks all requests for resources on Pantheon. However, known bots and crawlers do not count towards site traffic limits, nor do we meter requests for static assets (e.g. CSS or images).


Pantheon defines Visits as traffic from unique consumers in a 24 hour period. We identify unique consumers as a combination of user agent (device/browser) and IP address (network source).

Pages Served

Pages Served is the number of requests for resources generated by the CMS (WordPress or Drupal). Most commonly these are HTML web pages, but they also include non-HTML resources such as JSON, RSS, or XML-RPC. The number of Pages Served allowed for each Site Plan is five times the maximum monthly Site Visits.

For both metrics, we count based on the total volume of requests, which includes visitors receiving pages (or other CMS-generated resources) which are served from our Global CDN cache.

Imagine two visitors go to The first visitor exits from the home page, but the second visitor continues to browse two additional pages. This would be tracked as 2 Visits and 4 Pages Served.

Visits and visitors have different meanings. If one of the visitors returns again the next day, it would be counted as 3 Visits, but there'd be only 2 visitors.

Data is retained for the following amounts of time:

PeriodData Retention
Day28 days
Week12 weeks
Month12 months

Can I download or access the raw data directly?

Raw data is not currently available.

Why doesn't Pantheon's traffic match my analytics?

There are some inherent limitations with using an analytics suite (e.g. Google Analytics) when measuring site traffic. For details, see Traffic Limits and Overages.

How does Pantheon handle overages?

All non-Basic plans come with free overage protection. Where there is a pattern of consistent overage, we will align a site's plans with its load on the platform. For details, see Traffic Limits and Overages.

What about bots?

Pantheon-identified bots are excluded from the Visits and Pages Served Metrics.

What about redirects?

Only requests with a 2xx status count as pages served, so 301 redirects will not be included in metrics.

Can I see metrics for other environments?

Yes! Metrics are now available for the entire site or by environment via the Terminus metrics command.

Why don't I see any data, or why don't I see a full 12 months of data?

Data is shown for dates after March 18, 2018. If your site is not yet on the Global CDN data will not be available. To upgrade, see Pantheon Global CDN.

Are multiple user agents on the same originating IP address counted separately?

Yes. For example, multiple devices on the same home network visiting your site would each be considered a unique visitor.

Can I check metrics from the command line with Terminus?

Yes! Access to metrics via the Terminus metrics command. Install Terminus or update to the current release for access to the metrics command.
