${total_rate}
Total rate of all inbound client connections V8.13 and later
When a host connects to the listening sendmail server, the server forks a child copy of itself to handle the connection. Before forking, the server increments the total count of all connections. That count is then used to update the connection rate over time for all connections.
The rate is measured over an interval defined by the
ConnectionRateWindowSize option (ConnectionRateWindowSize on page 989),
which defaults to 60 seconds. Note that this total
rate (the rate for all
connections) differs from the client rate (the rate
for a particular connection).
The ${total_rate}
macro is not used in the standard configuration file
but is available for your use in rule sets of your
own design.
If you are interested in knowing the rate of
connections from individual clients, see the
${client_rate}
macro (${client_rate} on page 814).
${clienttotal_rate_rate} is transient.
If it is defined in the configuration file or in the
command line, that definition is ignored by
sendmail. Note that a
$& prefix
is necessary when you reference this macro in rules
(that is, use $&{total_rate}, not ${total_rate}).
