Sorry, Aki, I don't follow you. Did I do it wrong in the file 91-stats
that I shared in my original mail (attached here)?

# This file is based on https://wiki2.dovecot.org/Statistics
# Dovecot v2.1+ supports gathering statistics (CPU, disk usage, etc.)
# from mail processes (IMAP, POP3, LMTP, etc.) to the stats
# process. The stats process can later be queried what's going on in
# the system. With imap_stats plugin you can get per-command level
# statistics for IMAP commands.
#
# There are different "zoom levels" you can look at the statistics:
#
# * command: Per-IMAP command
# * session: Per IMAP/POP3 connection
# * user: Per user (all of user's sessions summed up)
# * domain: Per domain (all of domain's users summed up)
# * ip: Per IP address (all sessions from the IP summed up)
# * global: Everything summed up (2.2.16+)
mail_plugins = $mail_plugins stats
protocol imap {
mail_plugins = $mail_plugins imap_stats
}
plugin {
# how often to session statistics (must be set)
stats_refresh = 30 secs
# track per-IMAP command statistics (optional)
stats_track_cmds = yes
}
# You'll also need to give enough permissions for mail processes to be
# able to write to stats-mail fifo. For example if you use a single
# "vmail" user for mail access:
service stats {
fifo_listener stats-mail {
user = vmail
mode = 0600
}
}
# Memory usage configuration
# The stats process attempts to keep memory usage below a specified
# amount. This value is only approximate because of extra overhead
# caused by malloc() itself.
stats_memory_limit = 16 M
# Once the memory limit is reached, oldest statistics are freed from
# memory. Different statistics levels have different timeout limits,
# which are configured in:
stats_command_min_time = 1 mins
stats_domain_min_time = 12 hours
stats_ip_min_time = 12 hours
stats_session_min_time = 15 mins
stats_user_min_time = 1 hours
service stats {
inet_listener {
address = 127.0.0.1
port = 24242
}
}
