I have a low quality #geigercounter counter in my garage (it’s a RadiationD v1.1(CAJOE) if your interested). Ive linked up a #nanopi and monitor for ‘counts’ using a gpio and a c program (https://git.solarcene.community/smallsolar/nano_geiger_counter) - it’s definitely poor quality as I get 3 CPM on average which is below what it should do.
I noticed on my #grafana setup that something has changed…
On to the next one: Learn #Grafana 10x by Eric Salituro. Excited to finally learn the hidden treasures and wisdoms of Grafana after using it more and more in the last couple of years...
It's been a steep learning curve but it's cool that most of the stuff just works (TP-Link #Kasa and #Tapo, #Ikea Zigbee, #Philips#Hue (using the Hue Bridge, not directly connected to my Zigbee coordinator). Some stuff this uses the cloud (but can be used locally), other stuff takes out the cloud entirely. (1/2)
#HomeAssistant is quite cool in the visualisation as well. It's simple (but at times limiting in the UI) -- but quite simple to put together a #dashboard. I could connect #Grafana as well but that’s... for (much) later.
I've been shifting focus at work, from performance engineering to observability, and that means learning a whole lot. More learning in public! First up: #loki. It's a databases for logs with some interesting design decisions that make it more performant than other logs databases. Here's a video I made with my colleague, Jay Clifford, to share what we've learned, including a demo app that ties in Loki, Grafana, and Alloy: https://youtu.be/1uk8LtQqsZQ
Playing with #Grafana and loading a local CSV.
I've got data from several sources in the file, the source name is in the first column of the CSV, how can I get grafana to plot four different plots, one for each source name?
