Frees metrics.

Get the time immediately after the [classmessage] completed the connection to the server. This includes the time for the proxy negotiation and TLS handshake.

It will be 0 if no network connection was required to fetch the resource (a persistent connection was used or resource was loaded from the local disk cache).

Get the time immediately before the [classmessage] started to establish the connection to the server.

It will be 0 if no network connection was required to fetch the resource (a persistent connection was used or resource was loaded from the local disk cache).

Get the time immediately after the [classmessage] completed the domain lookup name for the resource.

It will be 0 if no domain lookup was required to fetch the resource (a persistent connection was used or resource was loaded from the local disk cache).

Get the time immediately before the [classmessage] started the domain lookup name for the resource.

It will be 0 if no domain lookup was required to fetch the resource (a persistent connection was used or resource was loaded from the local disk cache).

Get the time immediately before the [classmessage] started to fetch a resource either from a remote server or local disk cache.

Get the number of bytes sent to the network for the request body.

This is the size of the body sent, after encodings are applied, so it might be greater than the value returned by [methodmessageMetrics.get_request_body_size]. This value is available right before signalmessage[wroteBody] signal is emitted, but you might get an intermediate value if called before.

Get the request body size in bytes. This is the size of the original body given to the request before any encoding is applied.

This value is available right before signalmessage[wroteBody] signal is emitted, but you might get an intermediate value if called before.

Get the number of bytes sent to the network for the request headers.

This value is available right before signalmessage[wroteHeaders] signal is emitted, but you might get an intermediate value if called before.

Get the time immediately before the [classmessage] started the request of the resource from the server or the local disk cache.

Get the number of bytes received from the network for the response body.

This value is available right before signalmessage[gotBody] signal is emitted, but you might get an intermediate value if called before. For resources loaded from the disk cache this value is always 0.

Get the response body size in bytes.

This is the size of the body as given to the user after all encodings are applied, so it might be greater than the value returned by [methodmessageMetrics.get_response_body_bytes_received]. This value is available right before signalmessage[gotBody] signal is emitted, but you might get an intermediate value if called before.

Get the time immediately after the [classmessage] received the last bytes of the response from the server or the local disk cache.

In case of load failure, this returns the time immediately before the fetch is aborted.

Get the number of bytes received from the network for the response headers.

This value is available right before signalmessage[gotHeaders] signal is emitted, but you might get an intermediate value if called before. For resources loaded from the disk cache this value is always 0.

Get the time immediately after the [classmessage] received the first bytes of the response from the server or the local disk cache.

Get the time immediately before the [classmessage] started the TLS handshake.

It will be 0 if no TLS handshake was required to fetch the resource (connection was not secure, a persistent connection was used or resource was loaded from the local disk cache).
