Prometheus

Installation overview of node_exporter, prometheus and grafana

Prometheus is an open source systems monitoring and alerting toolkit originally build at Soundcloud. This blogpost shows how to install the needed components to do visualisation of linux system statistics via Grafana.

The setup consists of 3 components:
node_exporter, an exporter of system and hardware metrics.
prometheus, a metric collection and persistence layer.
grafana, the visualisation layer.

1. Preparation
The needed components are installed in the home directory of the user ‘prometheus’. In order for that user exist, it must obviously first be created:

Prometheus (3D)

I went to see Prometheus at the start of the month and wrote about it here.

A few days ago some friends asked me if I wanted to go with them to see it in 3D, so I did.

In 2D, the opening sequence was amazing. In 3D it was a bit of a let down. The opening credits (being 3D) jumped out at you and distracted from scenes behind. As for the rest of the film, some scenes worked and others didn’t. Pretty much any time there is movement, 3D sucks.

If I had gone to see the film in 3D first, I think my impression of it would have been quite different. If you have yet to see it, please go to the 2D version!

Cheers

PS. The Spiderman trailer was a mess in 3D. All of us commented on it being just a big blur. Truly terrible. I think the film will be good though (in 2D).

Prometheus…

Let me start by saying, I’m a big fan of all the Alien films, even Alien 3, which seems to be the least liked. Having said that, if someone said I had to pick one it would always be Alien. I watch that film several times a month. :)  Ridley Scott is renowned for being uncompromising, so I went into Prometheus with some seriously high expectations, which always worries me as it kinda sets you up for a fall…

The opening sequence of Prometheus is quite possibly the most beautiful thing I’ve ever seen on film. As I watched it I thought it was probably worth the £6 just to see that on a big screen…
