IAF log file status messages
The IAF sends status information to its log file every 5 seconds (the default behavior) or at time intervals you specify with the --logQueueSizePeriod option when you start the IAF. For example:
Status: ApEvRx=589 ApEvTx=2056000 TrEvRx=2056008 TrEvTx=587 vm=407200 pm=956240 si=0.0 so=0.0 oq=10
Where the fields have the following meanings:
Field
Description
ApEvRx
Number of Apama events received since the IAF started. These events were received from the correlator that the IAF is connected to.
ApEvTx
Number of Apama events sent since the IAF started. These events were sent to the correlator that the IAF is connected to.
TrEvRx
Number of events received by all transports in the IAF since the IAF started. These events were received from user-defined sources outside the correlator.
TrEvTx
Number of events sent from all transports in the IAF since the IAF started. These events were sent to user-defined targets outside the correlator.
vm
Number of kilobytes of virtual memory being used by the IAF process.
pm
Number of kilobytes of physical/resident memory being used by the IAF process.
si
The rate (pages per second) at which pages are being read from swap space.
so
The rate (pages per second) at which pages are being written to swap space.
oq
Sum total of events across all output queues of the IAF.
