Ok. I really was not sure what to set those polling intervals at. I guess I thought there was some sort of default and that is what they were doing. I basically copied your example now.
It took a few minutes, but I finally started getting a chart for this hub. Looks like the only issue (currently) is the platform version is still incorrect (not a big issue though).
I have also again temporarily reduced the backlog limit, as well as turned on debug logging.
Based on the oldest log it does appear you at some point had a failure writing to InfluxDB that was resolved. That is good we got that working and that is likely the cause of of it not showing up.
I expect this will resolve in less then 24 hours. My settings don't update that but every 24 hours.
I've been going in circles for the last 24 hours on this and wondering if anyone has different ideas.
I had the Hub Info dashboard set up perfectly in Grafana yesterday, but woke up this morning to find that the data stopped updating within Grafana in the wee hours. I couldn't get it restarted, so I finally went nuclear and re-setup the whole flow (Logger --> Influx --> Grafana) from scratch, but now after many tries the Grafana dashboard only produces "No data" in every panel. I'm using Cloud for both Influx and Grafana.
Influx Logger is working great -- HE log shows the data is getting to Influx just fine.
Within InfluxDB, I can use the Data Explorer to interrogate the data -- AFAICT I see all the values and dimensions that I would expect
In Grafana, my Connection to InfluxDB, which is Flux, tests successfully: "Data source is working--buckets found". And, like Influx, I can explore the data from within Grafana and see my handful of hubs with their primary data (dbsize, cpu, etc.)
But the Grafana panels still show up empty, even though I'm using last 2 days as the lookback period
Note also, I have selected the correct Bucket at the top of the dashboard, yet when I click "Device Name", my individual hubs don't show up like they did before.
I created the Grafana dashboards the same way each time--by importing the standard dashboard from here. The structure of the panel looks fine--there's just no data.
I feel like I'm missing/forgetting something simple, but I've reviewed the steps like ten times (no joke), and I'm going blind.
Is the clock possibly off on something, and the data is getting logged with an incorrect time stamp? Or if the Grafana host is way off on time "last 2 days" from its clock might be empty.
Make sure you are sending the 'cpuPct' attribute, that is what it looks for in the hub/device name query list to check that it is a hub info device.
I had previously installed and used Mavvrick58's Pi image and had this all up and runnning. I then had a HDD failure and wanted to start again.
This time I followed these instructions, installled InfluxDB 2.x and got some of the suggested boards. Now I wanted to create my own and somehow managed to do that when I was on InfluxDB 1.x, but now I see there is a more advanced (difficult) query language.. and.. it is being put into maintenance mode.
Is there a way to change my InfluxDB to us InfluxQL instead of Flex? If not, is there a way to uninstall InfluxDB 2.x so I can install InfluxDB 1.x?
Generally speaking a error code 500 represents "internal server error" responce which is a server side problem. Do you use the cloud option for InfluxDB or a locally hosted solution.
For those interested, there is a docker setup for InfluxDB and Grafana HERE.
Basic instructions are on the page. Once you have the files in the location you wish, and edited the variables in the .ENV file, run docker compose up to start up servers (wait a few minutes as there is a lot for Grafana to download). Then configure InfluxDb Logger to point the InfluxDB server, and then go to your Grafana server. Once in Grafana, import the Hub Info Dashboard
If you are not familiar with docker the benefits can be reduced install time for the servers, easy backup of the data files, and server upgrades.
Other smarter peeps here were the key.
