Measures reported by LtmNetworkConnTest

This test helps administrators to figure out how well the TCP and UDP connections are established on the target F5 Traffic Manager. Using this test, administrators can figure out the number of TCP and UDP connections that failed, the connections that were in OPEN state etc. This way administrators can figure out connection bottlenecks which when left unattended will lead to network congestion.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Tcp_conn_established Indicates the total number of TCP connections established to the traffic manager. Number  
Tcp_conn_accepted Indicates the number of TCP connections accepted by the traffic manager. Number  
Tcp_conn_not_accepted Indicates the number of TCP connections that were not accepted by the traffic manager. Number Ideally, the value of this measure should be zero. If too many TCP connections are not accepted, then it is indicative of a connection bottleneck when prolonged may lead to network congestion.
Tcp_conn_failed Indicates the number of TCP connections that failed on the traffic manager. Number Ideally, the value of this measure should be zero.
Tcp_open_connection Indicates the number of TCP connections to the traffic manager that were in OPEN state. Number A low value is desired for this measure.
Tcp_Conn_in_Timewait Indicates the number of TCP connections to the traffic manager that were in TIME-WAIT state. Number A low value is desired for this measure.
Udp_conn_established Indicates the number of UDP connections established on the traffic manager. Number  
udp_conn_accepted Indicates the number of UDP connections accepted by the traffic manager. Number  
Udp_conn_not_accepted Indicates the number of UDP connections that were not accepted by the traffic manager. Number Ideally, the value of this measure should be zero. If too many TCP connections are not accepted, then it is indicative of a connection bottleneck when prolonged may lead to network congestion.
udp_conn_failed Indicates the number of UDP connections that failed on the traffic manager. Number Ideally, the value of this measure should be zero.
Udp_open_connection Indicates the number of UDP connections to the traffic manager that were in OPEN state. Number A low value is desired for this measure.
