Integration Details<\/h3>\n\n\n\n
Data collection is implemented by the integration of MQTT logging. It uses a secure connection to TDengine hosted servers.<\/p>\n\n\n\n
The events currently logged are:<\/p>\n\n\n\n
- \n
- connect<\/li>\n\n\n\n
- disconnect<\/li>\n\n\n\n
- start<\/li>\n\n\n\n
- stop<\/li>\n\n\n\n
- level<\/li>\n\n\n\n
- ota <\/li>\n<\/ul>\n\n\n\n
Each message includes the device ID and software version. The ID is always redundant because it is used as the user ID for MQTT login. The version is redundant after the first time. Ideally it would only be included with the connect event. (Minimizing message size is important as the on-device network transmit buffers can become full when connectivity is weak, requiring a connection reset.) <\/p>\n\n\n\n
The mosquitto_sub tool is a convenient way to monitor MQTT events. There are many ways to install mosquitto if you don’t have it already. To monitor all Lyric events on TDengine server,, use this command line:<\/p>\n\n\n\n
The output looks like this:<\/p>\n\n\n\n
{"event":"connect","id":"FDD3F6F0688784214A606AADDD01E336","version":"0.8.7"}\n{"event":"start","title":"Calm","name":"Manual","level":1,"id"...\n{"event":"stop","id"...\n{"event":"start","title":"Calm","name":"Guided","level":1,"id"...\n{"event":"level","level":2,"id"...\n{"event":"level","level":3,"id"...\n{"event":"level","level":1,"id"...\n{"event":"stop","id"...\n{"event":"disconnect","id"...<\/code><\/pre>\n\n\n\nVisualization<\/h3>\n\n\n\n
Once these semi structured events are hosted on TDengine\u2019s server, picking a visualization tool is easy as well, we picked Grafana as it is highly customizable. End results are simple to digest, actionable, real time usage data on the Lyric that we depend on everyday!<\/p>\n\n\n\n

We see these benefits of using TDengine<\/p>\n\n\n\n
- \n
- Easy integration, clear documentation, took us just a few lines of code to start collecting data<\/li>\n\n\n\n
- TDengine\u2019s service is fast and reliable, with real time data ingestion and high availability<\/li>\n\n\n\n
- Highly customizable data visualization tooling, many integration possibilities<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
