With reference to the shown interval of time («Cleared 5 days 08:32:20 ago») these counters show the number of:

`CHR`	Characters received/sent by all control sessions from TCP.
`REQ`	All HTTP/HTTPS request messages.
`REQ-GET`	GET requests. The GET method is used to retrieve information from the given server using a given URI. Requests using GET should only retrieve data and should have no other effect on the data.
`REQ-POST`	POST requests. A POST request is used to send data to the server, for example, customer information, file upload, etc.
`REQ-PUT`	PUT requests. Uploads a representation of the specified URI.
`REQ-OPTIONS`	OPTIONS requests. Returns the HTTP methods that the server supports.
`RSP-BUF-OVR`	Response buffer overflow, it occurs when the HTTP request generates a response that has a higher amount than the output buffer used by the session.
`DENIED-IP`	HTTP requests received by the server from not allowed source IP address. The not-allowed is a client whose IP address is not present in `IPSRC` and `IPSRCLIST` parameters configuration.
`BANNED-IP`	Requests that was discarded because the source IP was banned by IPBAN service.

	Note
	The d se http command shows statistic information in an extended format including shown for each session.
