An updated version of Open Monitoring Distribution (OMD) is available at the Bananian site here. They've build it for the ARMv7 (BananaPi, Raspberry Pi 2 & 3, OrangePi). I've written a complete install manual for version 1.00 which should work for version 1.30 too. Just make sure you use Raspbian Jessie. The related Check_mk_agent files can [...]

I've upgraded my domotica setup with a Philips Hue. Before I switched the lights using a remote control or via Node-Red and using the cheap 433 Mhz wall outlet switches of Elro, Klik Aan/Klik Uit, Action, and so on. Since the install of the Hue I was missing the remote control to easily switch the [...]

Mac OS X – write images to SD Card with high speed

By | 2016-10-30T21:20:15+00:00 February 13th, 2015|Computer How-To, RaspberryPi, Tech, Uncategorized|

Writing SDCard images using my Macbook took way to long, up to half an hour to write one simple Raspberry Pi image to a SDCard. I just did what many instructions told me to do. You will probably recognize this command: dd if=/path/to/image/file.img of=/dev/disk3 bs=1m  (where /dev/disk3 depends on your system). Then I came across [...]

Limit SD Card writes on Rasberry Pi using Ramlog

By | 2016-10-30T21:20:15+00:00 January 17th, 2015|Computer How-To, Tech|

A SD card has a limited amount of writes it can handle. The Raspberry Pi will write to log files a lot and reduce the lifetime of your SD Card. Update 3-2-2016: RamLog seems not to be compatible with Debian Jessie. I haven't tried it yet but I have found a blog that might offer [...]

Raspberry Pi Open Monitoring Distribution setup guide

I use a setup of some Raspberry Pi's to monitor my own systems and some systems of my customers. My main goal is to be informed on system status (warnings and criticals) via one portal and preferably before my customers notice incidents on their systems. There is no need for expensive and energy consuming systems [...]
