rsync transfer data munin plugin - debian 10

For new installations the provided rsync_bytes plugin doesn't work. Here is rewrittend (and path-hardcoded) version which does work.

Please remember that the rsync logfile must be outside the /home directory, see here

Before use, install logtail.

rsyncd_bytes.sh

#!/bin/bash
#
# Plugin to monitor rsyncd.
# based on previous work by jintxo
#
# Parameters understood:
#
#       config   (required)
#       autoconf (optional)

# https://serverfault.com/questions/1004695/munin-node-plugins-on-debian-10-cannot-read-from-home-directories-debian-9-work
# munin-node package in Debian 10 includes /lib/systemd/system/munin-node.service, which sets ProtectHome=true. Debian 9's munin-node package does not have this file.
# Setting ProtectHome=read-only is one solution, or even ProtectHome=false to include write access. However the ProtectHome flag exists for good reasons. Arranging for the plugin to read its data

mktempfile () {
mktemp -t $1
}

# make sure these values are set correctly:
RSYNCD_LOG=/var/log/rsync.log
LOGTAIL=/usr/sbin/logtail
STATEFILE=/var/lib/munin-node/plugin-state/nobody/rsync-bytes.offset
