Retrieving connections information

Hello,

We are moving from a HA proxy based load balancing infrastructure to F5. We need to keep the current values sent in the logs by the HA proxies for data analytics purposes. Although we've been able to get most of the needed values, we can't retrieve the following ones using an iRule:

• Current connections in a node.
• Current connections globally to F5.
• Total number of bytes transmitted from the server to the client when the log is emitted.
• Number of connection retries experienced by one session when trying to connect to the server.
• Total number of requests which were processed before this one in the server queue. It makes it possible to estimate the approximate server's response time by dividing the time spent in queue by the number of requests in the queue.

Is possible to retrieve this data?

Thanks.
