Hi Awan,

Use Distribution setting as == Replicated

Default is Adaptive

There are three options for this Distribution setting:

• Adaptive == Default Setting

  This is the default method and uses the same distribution method as previous BIG-IP versions. When set to adaptive, the BIG-IP system selects one pool member from the HSL pool, establishes a connection, and sends all of the HSL traffic to this remote log server until either the rate of the HSL traffic exceeds what the remote log server is capable of accepting or the HSL connection to the remote log server is lost. When this happens, the BIG-IP system selects the next pool member from the HSL pool, establishes a new connection, and sends the rest of the HSL traffic to the next remote log server.

• Balanced

  This method directs the BIG-IP system to use the load balancing method that is configured in the HSL pool to pick a pool member every time the system attempts to send a log.

• Replicated

  This method replicates each log to all pool members of the HSL pool. This method is typically used when you want to have the same set of logs on another backup remote log server.

  Unless you specifically require the BIG-IP system to load balance HSL traffic between the remote log servers of the assigned HSL pool, or replicate HSL traffic to all pool members, F5 recommends that you use the default HSL traffic distribution method (adaptive).
