It is very hard to see the real values in the postfix queue when they are overlapping. Having a stacked graph eleviates this whil still retaining all the necessary data.

postfix_mailqueue_ - Plugin to monitor postfix mail spools per running postfix

|
=head1 ABOUT

|
A guide to postfix mail queue manageent can be found at

A summary:

|
|
|
|
=item maildrop
|
|
|
|
Messages that have been submitted via the Postfix sendmail(1) command,
|
|
but not yet brought into the main Postfix queue by the pickup(8)
|
|
service.
|
|
|
|
=item hold
|
|
|
|
Messages placed in the "hold" queue stay there until the administrator
|
|
intervenes
|
|
|
|
=item incoming
|
|
|
|
Inbound mail from the network, or mail picked up by the local
|
|
pickup(8) daemon from the maildrop directory.
|
|
|
|
=item active
|
|
|
|
Messages that the queue manager has opened for delivery. Only a limited number
|
|
of messages is allowed to enter the active queue (leaky bucket strategy, for a
|
|
fixed delivery rate).
|
|
|
|
=item deferred
|
|
|
|
Mail that could not be delivered upon the first attempt. The queue manager
|
|
implements exponential backoff by doubling the time between delivery attempts.
|
|
|
|
=item corrupt
|
|
|
|
Unreadable or damaged queue files are moved here for inspection.
|
|
|
|
=back
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
Uses the last part of the symlink name to get the postfix queue directory for the config file.
|
|
It then extract the queue path from the configuration file and uses it as a spooldir.
|
|
A environment spooldir can be set as a fallback.
