The counters plugin collects and provides several IKE performance counters.
The plugin is disabled by default (unless the stroke plugin is built) and can be enabled by adding
--enable-countersto the ./configure options.
The plugin has been introduced with 5.6.1, its functionality was previously included in the stroke plugin.
Counters are collected globally and per connection name. However, the latter has some limitations e.g. if the initially selected connection is switched due to the authentication method or the exchanged identities. In which case, for example, no IKE_SA_INIT messages will be recorded for the name of the second connection. Some counters also will never record connection specific numbers (e.g. the number of messages with invalid IKE SPI).
