Statistics for server response time

Can the statistics provided from PoolMember::get_statistics provide me with the average and maximum response time of the pool member for traffic through BigIP?

 

 

The statistics STATISTIC_MEAN_CONNECTION_DURATION and STATISTIC_MAXIMUM_CONNECTION_DURATION look promising.

 

 

Also, if these are the right statistics, is the duration in milliseconds?

  • The *_CONNECTION_DURATION statistics are available only on the virtual server object. These statistics represent the minimum, mean, and maximum duration of connections on that VIP, not the response time.

     

     

    For the PoolMember, the following statistics are currently exposed:

     

     

    STATISTIC_SERVER_SIDE_BYTES_IN

     

    STATISTIC_SERVER_SIDE_BYTES_OUT

     

    STATISTIC_SERVER_SIDE_PAKCETS_IN

     

    STATISTIC_SERVER_SIDE_PACKETS_OUT

     

    STATISTIC_SERVER_SIDE_CURRENT_CONNECTIONS

     

    STATISTIC_SERVER_SIDE_MAXIMUM_CONNECTIONS

     

    STATISTIC_SERVER_SIDE_TOTAL_CONNECTIONS

     

    STATISTIC_PVA_SERVER_SIDE_BYTES_IN

     

    STATISTIC_PVA_SERVER_SIDE_BYTES_OUT

     

    STATISTIC_PVA_SERVER_SIDE_PAKCETS_IN

     

    STATISTIC_PVA_SERVER_SIDE_PACKETS_OUT

     

    STATISTIC_PVA_SERVER_SIDE_CURRENT_CONNECTIONS

     

    STATISTIC_PVA_SERVER_SIDE_MAXIMUM_CONNECTIONS

     

    STATISTIC_PVA_SERVER_SIDE_TOTAL_CONNECTIONS

     

    STATISTIC_TOTAL_REQUESTS

     

    STATISTIC_TOTAL_PVA_ASSISTED_CONNECTIONS

     

    STATISTIC_CURRENT_PVA_ASSISTED_CONNECTIONS

     

     

    Basically you can get at the connection and throughput statistics. Currently we don't expose response times/averages in the interfaces.

  • Joe,

     

     

    Are the statistics STATISTIC_MEAN_CONNECTION_DURATION and STATISTIC_MAXIMUM_CONNECTION_DURATION in milliseconds?

     

     

    Thanks,

  • It seems to be in milliseconds. A single request to a http virtual that takes 12ms for the entire client request/response is showing up as a duration time of 5. I'll get the wiki documentation updated with this.
