Instructions:
Here are several specific TCP and HTTP counters related to NetScaler.
 
tcp_err_syn_drop
# of times received Client SYNs dropped
 
tcp_tot_reuse_miss
# Client transaction didn't find a server connection in the reuse-pool that matches the client's requirements
 
tcp_tot_reuse_rst
# The number of client-side connections that have been reset and continue to reuse the original server-side connection associated with it.
- During the ADC processing, it is felt that the connection on the client side needs to be reset.
- During the ADC processing, the RST on the client-side connection is received, and the corresponding processing is performed.
 
tcp_tot_fin_pass_clnt_dont_reuse
# Client FIN passthrough to the Server because the PCB is marked for NOT to REUSE
 
tcp_tot_fin_pass_srvr_dont_reuse
# Server FIN passthrough to the Client because the PCB is marked for NOT to REUSE
 
http_err_noreuse_finpass
# The ADC has received a FIN for a transaction that is not yet completed.
 
http_err_noreuse_IncompleteHeader
# NO REUSE: the Incomplete header reassembly Failures
 
http_tot_for_reuse
# PCBs added to the REUSE Pool
 
http_err_noreuse_client
# Client Connections considered as invalid and skipped http tracking
 
http_err_noreuse_server
# Server Connections considered as invalid and skipped http tracking
 
http_err_noreuse_link_server
# NO REUSE: if http FA moves to unknown on clt req; svr_pcb's http state is also made unknown
 
http_err_noreuse_InvalidHeader
# Invalid HTTP response status
