Outstanding request per virtual server

Hi Ravindra,

you may take a look to the Virtual Server statistics. For HTTP traffic you will get independent counters for HTTP requests / responses...

(tmsh) show ltm virtual VS_MyVirtualServer profiles raw

Beside of this rather simple functionality you could also deploy some iRules on your Virtual Servers which are counting the individual request/response numbers of a given time-frame by using

[table -subtable]

entries.

when RULE_INIT {

    set static::statistic_lifetime 10   ; Seconds

}
when HTTP_REQUEST {

    if { [HTTP::path] eq "/show_stats" } then {

        set http_response "

    
        Requests: [table keys -subtable "[virtual]_request_counter" -count]
        Pending: [table keys -subtable "[virtual]_pending_counter" -count]
        Response: [table keys -subtable "[virtual]_response_counter" -count]
    
"

        HTTP::respond 200 content $http_response "Content-Type" "text/html" "Connection" "close"
        return

    }

     Initialize request ID label

    set request_id "[TMM::cmp_unit][clock clicks]"

     Update requests and pendings

    table set -subtable "[virtual]_request_counter" $request_id indef $static::statistic_lifetime
    table set -subtable "[virtual]_pending_counter" $request_id indef $static::statistic_lifetime

}
when HTTP_RESPONSE {

     Update responses and remove pendings

    table set -subtable "[virtual]_response_counter" $request_id indef $static::statistic_lifetime
    table delete -subtable "[virtual]_pending_counter" $request_id

}

Cheers, Kai
