| Re: [mosquitto-dev] Mosquitto persistence file didn't grows. |

Thanks for your suggestions, you're right: I was testing with
mosquitto_pub and I noticed that the client_id changes every
messages and I didn't specify the qos so "mosquitto_pub" goes
defaults to 0. clean_session is a parameter related to bridges, there isn't the same options for standard listeners, right? A "retry_interval 300" should be a safe value? Now I'm sending messages like this: mosquitto_pub -d -h myhost.mydomain.tld -i 2833-sviluppo -q 2 -t '/NLMG3MFQRDVCMZMW/id04/attrs' -m '{"status":3,"battery":2.0}' I stopped the IOT Agent which consumes messages from the mosquitto queue so I expect to see the mosquitto.db growing but is still at same size: -rw------- 1 systemd-bus-proxy systemd-bus-proxy 39 Feb 12 12:06 mosquitto.db
Thank you, Matteo Fracassetti.

Are you actually sure you have any subscribers that will be stored? remember, you need. * clean session false * stable client id * subscribe with qos >= 1 Finally, and unrelated, but you almost definitely do _not_ want retry interval down at 20.

I mounted a volume for logs and persistence file and everythings seems to work fine except for the persistence: The mosquitto.db files doesn't grows even if I stop any subscriptor which could empty queues. Write permissions on db path are fine, if I delete the file mosquitto.db, mosquitto creates it again when started. But nothing seems to be written into and when mosquitto logs to have written his in-memory database to the file, the mosquitto.db was touched and its "last time modified" updated accordingly.
