**vcl_on_compute_pass_requests** | Option<**i32**> | Number of requests that passed through the CDN without being cached for a VCL service running on Compute. | 
**vcl_on_compute_error_requests** | Option<**i32**> | Number of cache errors for a VCL service running on Compute. | 
**vcl_on_compute_synth_requests** | Option<**i32**> | Number of requests that returned a synthetic response (i.e., response objects created with the `synthetic` VCL statement) for a VCL service running on Compute. | 
**vcl_on_compute_edge_hit_requests** | Option<**i32**> | Number of requests sent by end users to Fastly that resulted in a hit at the edge for a VCL service running on Compute. | 
**vcl_on_compute_edge_miss_requests** | Option<**i32**> | Number of requests sent by end users to Fastly that resulted in a miss at the edge for a VCL service running on Compute. | 
**all_hit_requests** | Option<**i32**> | Number of cache hits for a VCL service. | 
**all_miss_requests** | Option<**i32**> | Number of cache misses for a VCL service. | 
**all_pass_requests** | Option<**i32**> | Number of requests that passed through the CDN without being cached for a VCL service. | 
**all_error_requests** | Option<**i32**> | Number of cache errors for a VCL service. | 
**all_synth_requests** | Option<**i32**> | Number of requests that returned a synthetic response (i.e., response objects created with the `synthetic` VCL statement) for a VCL service. | 
**all_edge_hit_requests** | Option<**i32**> | Number of requests sent by end users to Fastly that resulted in a hit at the edge for a VCL service. | 
**all_edge_miss_requests** | Option<**i32**> | Number of requests sent by end users to Fastly that resulted in a miss at the edge for a VCL service. | 
**all_status_1xx** | Option<**i32**> | Number of \"Informational\" category status codes delivered for all sources. | 
**all_status_2xx** | Option<**i32**> | Number of \"Success\" status codes delivered for all sources. | 
**all_status_3xx** | Option<**i32**> | Number of \"Redirection\" codes delivered for all sources. |

**all_status_5xx** | Option<**i32**> | Number of \"Server Error\" codes delivered for all sources. | 
**origin_offload** | Option<**f32**> | Origin Offload measures the ratio of bytes served to end users that were cached by Fastly, over the bytes served to end users, between 0 and 1. ((`edge_resp_body_bytes` + `edge_resp_header_bytes`) - (`origin_fetch_resp_body_bytes` + `origin_fetch_resp_header_bytes`)) / (`edge_resp_body_bytes` + `edge_resp_header_bytes`). | 
**request_denied_get_head_body** | Option<**i32**> | Number of requests where Fastly responded with 400 due to the request being a GET or HEAD request containing a body. |
