  • Change Modified to collect TPS data from 30 seconds' average to 5 seconds' average.

    whatap.conf

    service_metrics_spike_enabled=false // If false, the data is collected every 5 seconds average.

  • Fixed Fixed the error where sometimes normal transactions are collected as the transactions delayed by more than 5 minutes.

    If the order of the start and end events of a transaction has been reversed via UDP communication, and the transaction end event has been processed first, Lost connection appears in the internal profile information after 5 minutes. Once the end event has been delivered first, it is supplemented to wait for the start event for 30 seconds.

    The cause of theLost connection in the internal profile information is as follows. It stops collection if it failed to collect the end event for 5 minutes after a transaction start event.

    • In case the actual execution time of a transaction is more than 5 minutes.
    • In case the collection of transaction end event failed because Apache or php-fpm restarted or the shutdown killed the process immediately.
    • In case Apache or php-fpm has been forcibly terminated due to an unexpected error (segmentaion or sigbus can be confirmed by the error log content).
