It uses the Erlang standard log + mechanism <c>disk_log</c> for logging. The size and location of + the log files are configurable. A wrap log is used, which means + that when the log has grown to a maximum size, it starts from the + beginning of the log, overwriting existing log records. + </p> + <p>The log can be either a <c>read</c>, <c>write</c> or a + <c>read_write</c>. + </p> + + <section> + <title>Agent Logging</title> + <p>For the agent, a <c>write</c>, means that all <c>set</c> + requests and their responses are stored. No <c>get</c> requests + or traps are stored in a <c>write</c>. A <c>read_write</c>, + all requests, responses and traps are stored. + </p> + <p>The log uses a raw data format (basically the BER encoded + message), in order to minimize the CPU load needed for the log + mechanism. This means that the log is not human readable, but + needs to be formatted off-line before it can be read.
