No green thumb? No problem.
In celebration of #EarthDay on April 22, here's a simple #IoT project to keep your plants happy and healthy using #Arduino, #Prometheus, and #Grafana Cloud.
Happy gardening!
@tracketpacer #Prometheus and different exporters. Some devices now have native metrics endpoints…
The observability world loves a good rivalry — but this isn’t one.
#Prometheus and #OpenTelemetry are evolving together, not apart. Myrle Krantz, Director of Engineering, explains why.
@christopherkunz @heiseonline Gut gut. Habt ihr schonmal von #Prometheus, #blackboxexporter, und #Grafana gehoert? ;)
Oder Grafana Cloud synthetic monitoring?
For the 2nd straight year, half of all organizations invested more in #Prometheus & #OpenTelemetry.
This data is based on our 3rd annual Observability Survey, which features insights from 1,200+ respondents in observability.
Have you observed something similar in your team/organization?

I just created my first #prometheus exporter in #golang. Feel free to give feedback and submit patches.
Your chatmail relay is great for private conversations!
But it's also great for some Alertmanager infomails!
I recently discovered that diagnostic plugs in cars were more or less standard (OBD2) and that you could buy a plug reader for like 30 bucks. I also discovered that some OBD2 prometheus exporters exist.
So now basically my new project is to have a server in my car, like a RPi. It would srcap the OBD2 data locally and backfill it into my home prometheus database whenever the car gets into my home wifi range.

Want to dive deeper into #Grafana, #Prometheus #OpenTelemetry, or datasource plugins? 
Our hands-on labs at #GrafanaCON are where learning gets real. Tinker, test, and troubleshoot alongside Grafana experts. 
May 6 | Only with a GrafanaCON ticket

This new Asteroid Hauling activity is not fun at all! It needs some major fine tuning! The ship doesn't need to be listing so drastically...The gravity Stabilizer should be helping out with that more. Either make the tilts less drastic or allow adjustment by more than one unit in the opposite direction at a time, probably a bit of both. I tried three times and got further the third time but only by speeding my speech way up and trying frantically to keep myself level but it still got away from me. The output is too verbose combined with it introducing roundtime randomly per each correction. I thought it might be based on the damage of the Gravity Stabilizer or another component, but that doesn't seem to be the case as far as I can tell. There's challenging and then there's ridiculously challenging... #Prometheus
If you've tried both Thanos and Mimir, which do you prefer? Feel free to comment why below 
So, I've been using Thanos to receive and store my prometheus metrics long term in a self hosted S3 bucket. Thanos also acts as a datasource for my dashboards in Grafana, and provides a Ruler, which evaluates alerting rules against my metrics and forwards them to my alertmanager. It's ok. It's certainly got it's downsides, which I can go into later, but I've thinking... what about Mimir?
How do you all feel about Grafana's Mimir (source on GitHub)? It's AGPL and seems to literally be a replacement of Thanos, which is Apache 2.0.
Thanos description from their website:
Open source, highly available Prometheus setup with long term storage capabilities.
Mimir description from their website:
...open source software project that provides horizontally scalable, highly available, multi-tenant, long-term storage for Prometheus and OpenTelemetry metrics.
Both with work with alloy and prometheus alike. Both require you to configure initially confusing hashrings and replication parameters. Both have a bunch of large companies adopting them, so... now I feel conflicted. Should I try mimir? Poll in reply.
Aaaaaah pushgateway you heathens whyyyyy #prometheus #kubecon
I like deep dives and I cannot lie #kubecon #prometheus #cadvisor
Very happy to discover how easy it is to extend `node_exporter` with custom metrics:
Add `--collector.textfile.directory=/some/place` to the daemon's arguments (e.g. via ARGS in `/etc/default/prometheus-node-exporter`), and write `*.prom` files in that directory with your favorite tool, and **boom!**

Creating Grafana alerts is something I'm less comfortable with, but I'm starting to get the hang of it…
Interested in #containers, #docker, #OCI and #guix #declarative #configuration?
Watch Giacomo Leidi's talk about self-hosting @forgejo using Guix's container backed configuration. Check it out 
His Gocix project shows how to bring together container-based software while benefiting from the resilience of declarative configuration! He has services for #prometheus #grafana #traefik #bonfire and more!
Want #cloudnative but with the power of #declarative configuration? The recoverability of #transactions for system configuration?
Wednesday it's the online #guix meet-up! With a great talk by @paulbutgold
about running docker / oci containers using the Guix configuration system.
His Gocix project has #prometheus, #grafana, #forgejo, #conduit and #traefik examples.
Meet-up details:
every now and then I'm like "I want to learn a new metrics/timeseries db" ... then I start doing that and I'm like "ughhh, I've been doing this in at least 6 different ways over the last 15 years, why do it again"
I really miss Graphite
It's the #DayOfHelios / Sol's Day / #Sunday! 
"#Zeus then sent #Hermes to Atreus and told him to get Thyestes to agree that Atreus should rule [Argos], if #Helios (the Sun) should journey backwards. Thyestes agreed, and Helios put his setting where he usually rose."
Pseudo-Apollodorus, Bibliotheca E2.12
#Prometheus, the creation of man, Roman relief
This week we talked about the #mythology of the #constellation #Centaurus
While the main story is about the centaur Chiron, his story also intersects with Prometheus, who was punished by Zeus to have his liver eaten by an Eagle every day... truly nightmare fuel 
To learn more about these #myths, check out our #podcast episode here: https://starrytimepodcast.podbean.com/e/centaurus-myths-and-retconstellations/
