If the logger is writing to the alternate log, and the error condition that caused it to switch has been
cleared, you can revert to the primary path by using the
evmreload -l command.
If a
forward command is specified, the logger executes the command when any incoming event matches
the forwarding filter. The logger then pipes the incoming event into the command’s
stdin stream.
The logger executes forwarding commands asynchronously and continues to handle events while com-
mands are running. However, to ensure proper sequencing, the logger allows only one instance of each
command to run at a time. If a command is running and another event arrives that matches the
forwarder’s filter, the event is queued until the command terminates. At which time the logger reruns it
with the next queued event. The size of each forwarder’s queue is limited and is controlled using the
maxqueue keyword. To minimize the chances of queuing or missing events, avoid using the forwarding
facility to run commands that may take significant time to execute. See evmlogger.conf(4) for more infor-
mation on setting the queue limit.
By default, only events posted through the local EVM daemon are handled by the logger’s event logs and
forwarders.
If an incoming event matches the suppression filter associated with an event log or forwarder, the event is
considered for suppression. For an event log, suppressing an event reduces the risk of wasting file
storage space by logging repeated instances of the same event. For a forwarder, suppressing an event
reduces the risk of sending replicated mail messages reporting the same event over a short period. For a
full discussion of the configuration values which control suppression see evmlogger.conf(4).
