My setup has mosquitto 1.4.12 using TLS and user/pass authentication, it is working without issues under Ubuntu 14.04 for quite some time.
Problem is that no data is being published to any $SYS broker status topics. I have reviewed the configuration and sys_interval is set to 10. Is anything else needed to have this working?
I've tried many clients (mosquitto_sub, paho-mqtt, mqtt.fx), so it looks like a wrong mosquitto config, not a client issue.
mosquitto.conf looks like this:
sys_interval 10
max_queued_messages 10000
max_inflight_messages 100
max_connections -1
connection_messages true
log_dest stderr
log_type error
log_type warning
log_type notice
log_type information
log_type all
log_timestamp true
password_file /etc/mosquitto/conf.d/jp.pw
acl_file /etc/mosquitto/conf.d/acl.conf
persistence true
persistence_location /var/lib/mosquitto/
persistence_file mosquitto.db
persistent_client_expiration 1m
autosave_interval 600
retained_persistence true
listener 8883
tls_version tlsv1.2
cafile /etc/mosquitto/ca_certificates/ca.crt
certfile /etc/mosquitto/ca_certificates/cert.crt
keyfile /etc/mosquitto/ca_certificates/cert.key
require_certificate false
allow_anonymous false
acl.conf has this, may be unnecessary:
