Postfix Input Plugin

This plugin collects metrics on a local Postfix instance reporting the length, size and age of the active, hold, incoming, maildrop, and deferred queues.

⭐ Telegraf v1.5.0 🏷️ server 💻 freebsd, linux, macos, solaris

Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See CONFIGURATION.md for more details.

Configuration

# Measure postfix queue statistics
# This plugin ONLY supports non-Windows
[[inputs.postfix]]
  ## Postfix queue directory. If not provided, telegraf will try to use
  ## 'postconf -h queue_directory' to determine it.
  # queue_directory = "/var/spool/postfix"

Permissions

Telegraf will need read access to the files in the queue directory. You may need to alter the permissions of these directories to provide access to the telegraf user.

This can be setup either using standard unix permissions or with Posix ACLs, you will only need to use one method:

Unix permissions:

sudo chgrp -R telegraf /var/spool/postfix/{active,hold,incoming,deferred}
sudo chmod -R g+rXs /var/spool/postfix/{active,hold,incoming,deferred}
sudo usermod -a -G postdrop telegraf
sudo chmod g+r /var/spool/postfix/maildrop

Posix ACL:

sudo setfacl -Rm g:telegraf:rX /var/spool/postfix/
sudo setfacl -dm g:telegraf:rX /var/spool/postfix/

Metrics

  • postfix_queue
    • tags:
      • queue
    • fields:
      • length (integer)
      • size (integer, bytes)
      • age (integer, seconds)

Example Output

postfix_queue,queue=active length=3,size=12345,age=9
postfix_queue,queue=hold length=0,size=0,age=0
postfix_queue,queue=maildrop length=1,size=2000,age=2
postfix_queue,queue=incoming length=1,size=1020,age=0
postfix_queue,queue=deferred length=400,size=76543210,age=3600
