About the Services menu
Last updated 2024-09-23
The Services menu contains links to two pages that display high-level metrics for your services:
- Service Overview: page that contains the Service Overview dashboard, which displays different information depending on if you are viewing a Deliver or Compute service.
- All Services: page that contains the All Services dashboard, which displays aggregated metrics from all of your services.
To access the Services menu, go to Observability > Services.
Before you begin
Be sure you know how to access the web interface controls before learning about the details you'll encounter here.About the Service Overview page
The Service Overview page gives you access to the Service Overview dashboard, which displays different information depending on if you are viewing a Deliver or Compute service.
Service Overview dashboard for a Deliver service
When a Deliver service is selected from the Service menu, the Service Overview dashboard displays the following metrics:
- Global POP Traffic: the map of Fastly's points of presence (POPs) that receive requests for your service. The map only appears when you are viewing live traffic.
- Hit Ratio: the percentage of cache hits to all cacheable content over time.
- Requests: the number of requests by cache response type.
- Bandwidth: the total bytes delivered.
- All Status Codes: the number of responses sent by status group.
- Error ratio: the number of cache errors.
- Status 3XX Details: the breakdown between the number of HTTP status 301s, 302s, 304s, and other 3XX requests.
- Status 4XX Details: the breakdown between the number of HTTP status 400s, 401s, 403s, 404s, 416s, 427s, and other 4XX requests.
- Status 5XX Details: the breakdown between the number of HTTP status 500s, 501s, 502s, 503s, 504s, 505s, and other 5XX requests.
- Misses: the number of cache misses.
- Object Sizes: the number of objects served by payload size.
- Hit Time: the average amount of time spent processing cache hits.
- Miss Time: the average amount of time spent processing cache misses.
- Header & Body Bytes Transferred: the relative values of bytes transferred when serving the body and header portions of HTTP requests.
- Log Lines: the number of log lines sent.
- Log Bandwidth: the total log bytes sent.
- Origin Latency: the distribution of origin latency times that approximate how quickly your origin is responding to Fastly. This histogram only appears when you are viewing live traffic.
- Origin Latency Percentiles: the origin latency percentiles that approximate how quickly your origin is responding to Fastly. Each percentile is indicated by
pn
, wheren
is the percentile number.pn
meansn
% of all requests had an origin latency value that is less than or equal to the value on the y-axis. For example, if the value ofp95
is8s
, 95% of all requests had an origin latency that was less than or equal to 8 seconds. This graph only appears when you are viewing live traffic. - Cache Coverage: the percentage of your site that you are caching with Fastly.
- HTTP Versions: the number of requests using HTTP/1.1, HTTP/2, and HTTP/3(QUIC).
- Error Ratio by Region: the percentage of cache errors per region.
- TLS versions: the number of requests using TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 protocols.
The dashboard also displays collections of metrics that you can expand and collapse by clicking the collection name. The collections include:
- Image Optimizer: metrics for your services that relate to image optimization.
- WebSockets: metrics for your service that relate to WebSockets.
- Fanout: metrics for your service that relate to Fanout.
Service Overview dashboard for a Compute service
When a Compute service is selected from the Service menu, the Service Overview dashboard displays the following metrics:
- Global POP Traffic: a map of Fastly's points of presence (POPs) that receive requests for your service.
- Requests: the total number of requests that were received for your service by Fastly.
- Response status codes: the total number of response status codes by category delivered by Compute.
- Total resource limits exceeded: the number of times a guest exceeded its resource limit, includes heap, stack, globals, and code execution timeout.
- Memory Resource Limits Exceeded: the number of times a guest exceeded its heap, stack, and global limits.
- Backend Requests Errors: the number of backend request errors, including timeouts.
- Edge Code Errors: the number of times a service experienced an edge code error.
- Guest Runtime Errors: the number of times a service experienced a guest runtime error.
- Bytes Received by Compute: the total bytes received by Compute.
- Bytes Transferred to Client: the total bytes sent from Compute to end user.

- Log Bandwidth: the total bandwidth size of the logs sent to your endpoints from Fastly.
About the All Services page
The All Services page gives you access to the All Services dashboard, which displays aggregated metrics from all of your services. Specifically, it displays the following overview metrics:
- Requests: a graph displaying the number of requests served across your account.
- Bandwidth: a graph displaying the number of bytes served from Fastly's servers to your website's visitors.
- Error Ratio: a graph displaying the number of cache errors across your account.
The dashboard also displays collections of metrics that you can expand and collapse by clicking the collection name. The collections include:
- Deliver: aggregated metrics from all of your Deliver services. The metrics in this collection mirror the metrics on the Service Overview dashboard for a Deliver service.
