4.1.8.4 System Logs
System logs are internal concentrator operation logs. They contain internal debugging information that
may be requested by support.
By default, the system logs are not transferred to the FTP server. To do so, the “Dump gateway logs”
option must be enabled on the server conguration page:
System log les are also transferred automatically when a connection is forced via the server conguration
page, by clicking on the “Connect” button or via the SMS command “connect”.
The le name is composed of the concentrator’s uid, followed by “SYSTEM” and the date and time the le
was uploaded to the server: “WPM00BDE4_SYSTEM_210211_181543.log.gz”
4.2 The MQTT/MQTTS server
The operation of an MQTT or MQTTS server is identical. But it is preferable to use an MQTTS server which
integrates layers of security unlike an MQTT server. The description in this chapter is equally valid for all
types of MQTT servers.
Settings:
The MQTT server is dened by the following parameters:
• An address: This address can be an IP address or a domain name.
• An MQTT connection port (default 1883 for MQTT and 8883 for MQTTS).
• A server identication: depends on the type of MQTT server chosen. Identication can be done
either by a simple username and password or by certicates and a key to be imported into the
concentrator.
• An application identication: Unique identier of the server allowing to have its own application
space.
