I will share a little workaround in order to re-establish Prometheus service back in the game.

Origin of issue:

I’ve had an issue with my local network at home by the ISP provider, I had have shut down my RaspberryPi and other devices.

Then when I could solved the issue and all my devices were up and running I checked up my services and I found that Prometheus got stuck by a “mmap: invalid argument” message.

Setup monitoring system [Grafana+Prometheus] in RaspberryPi (Part1)

Wed, 03 Feb 2021 00:00:00 +0000

On this post I will explain how I set up a Grafana + Prometheus into a RaspberryPi with Raspbian.

Here it’s a little design where explains how it is the implementation I did:

🔵 Server: RaspberryPi 3B+

Services to install(server side):
1. Grafana
2. Prometheus (Metric collector and database)
3. Node Exporter (collector worker)

🟢 Clients: Raspberrypi Zero Fedora Workstation Debian VPS

Services to install(client side):
1. Node Exporter (collector worker).

🔵 Lets start from the server side.

Monitoring with Cockpit

Mon, 11 Jan 2021 00:00:00 +0000

On this post we are going to talk about cockpit how to monitoring and manage your GNU/Linux infrastructure. Based on the official description, Cockpit project is pretty easy to use, install and integrate, you can manage and add servers by ssh credentials to your dashboard, showing logs, monitoring containers(podman/docker), services running, disk usage, etc.

I’ve using it around 1 year, the only thing I cannot see it’s an alert tool or event trigger, maybe for the next release; is developed by RH team and open source, it’s already integrated in some of the GNU/Linux distribution ( RH, debian, ubuntu, fedora, etc).

Setup Podman service in Silverblue by Systemd

Into my Devops learning path 👨‍💻 I decided to deploy a monitoring centre into my workstation where I could be able to watch my containers, resources, logs, etc and continue improving my knowledge, in my case I’m using Silverblue developed by Fedora so in here it’s a little bit different the setup; as monitoring tool I choose Cockpit for its great integration and support.

Workstation: Silverblue 🖥️
Container engine: Podman ⚙️
Monitoring tool(app/service):Cockpit 📦

I splinted out the instructions in 4 simple parts:

Setup Grafana in Raspbian (Raspberrypi)

Tue, 09 Apr 2019 00:00:00 +0000

The below post is a simple explanation I did time ago, if you want further info and better explanation about how to setup a monitoring system into your Raspberripy please go to here.

Raspbian version:9.8

$ uname -r
4.14.98-v7+
$ uname -m
armv7l

Version installed on my RasPi: Grafana v6.0.2 (3f4c2e7)

Download Grafana package for your correct Raspi ARM
$sudo dpkg -i grafana_6.1.3_armhf.deb
$systemctl start grafana-server
$systemctl status grafana-server
then you will see from the status propmt the address=0.0.0.0:3000

msg="HTTP Server Listen" logger=http.server address=0.0.0.0:3000
