Connection Timeout Kernel Variables
Equalizer uses a number of kernel variables to track connection timeouts, as shown in the table
below. You can use the sysctl command to display kernel variables. The two basic formats of this
command are:
sysctl variable_name
Displays the kernel variable variable_name.
sysctl -a > file
Displays all kernel statistics. This is a long list, so we recommend
capturing the list to a file.
eq.idle_timeout
The current setting of the Layer 4 global networking idle timeout
parameter.
eq.idle_timedout_count
A Layer 4 counter incremented when a connection is terminated because
the idle timeout expired.
eq.stale_timeout
The current setting of the Layer 4 global networking stale timeout
parameter.
eq.l7lb.timeouts
The total number of Layer 7 connections dropped because a connection
timer expired.
eq.l7lb.http.client_timeouts
The total number of Layer 7 (HTTP and HTTPS) connections that were
terminated because the client timeout expired.
eq.l7lb.http.connect_timeouts
The total number of Layer 7 (HTTP and HTTPS) connections that were
terminated because the connect timeout expired.
eq.l7lb.http.server_timeouts
The total number of Layer 7 (HTTP and HTTPS) connections that were
terminated because the server timeout expired.
Note that there are also some kernel variables associated with Secure Socket Layer (ssl) client
connections, such as when someone logs into Equalizer over an SSH connection. These variables
are not incremented by HTTPS connections:
eq.l7lb.ssl.total_clients
eq.l7lb.ssl.current_clients
eq.l7lb.ssl.max_clients
eq.l7lb.ssl.requests
