|| ### Items |Name|Description|Type|Key and additional info| |----|-----------|----|-----------------------| |Nginx: Get stub status page|The following status information is provided:
`Active connections` - the current number of active client connections including waiting connections.
`Accepted` - the total number of accepted client connections.
`Handled` - the total number of handled connections. Generally, the parameter value is the same as for the accepted connections, unless some resource limits have been reached (for example, the `worker_connections` limit).
`Requests` - the total number of client requests.
`Reading` - the current number of connections where Nginx is reading the request header.
`Writing` - the current number of connections where Nginx is writing a response back to the client.
`Waiting` - the current number of idle client connections waiting for a request.
