Quick manual Kafka OpenNMS stack

Thu, 05 Aug 2021 00:00:00 +0000

We have gathered a few ready-to-run Docker stacks in our public stack-play GitHub repository. But sometimes you need Kafka, Zookeeper and OpenNMS quickly on a baremetal deployment without Docker. Here a few quick notes how to get the bare minimum up and running.

Zookeeper

Install OpenJDK 11 JRE

sudo apt install -y openjdk-11-jre

Create a user for zookeeper

sudo adduser --system --home /opt/zookeeper --disabled-login zookeeper

Create a logs directory

sudo mkdir /var/log/zookeeper
sudo chown zookeeper:nogroup /var/log/zookeeper -R

Install zookeeper

Send notifications with Signal

Thu, 01 Nov 2018 00:00:00 +0000

In some cases it is nice to have notifications from OpenNMS in a separate channel on a smartphone and you don’t want to pay for SMS. Here is a tutorial where I use Signal using the signal-cli.

This Howto will describe how to download the latest signal-cli tool, link it to your existing Signal account and how to configure OpenNMS to use it as a notification target. You should have already an OpenNMS Horizon or Meridian running and you need a Signal account with the Signal app installed and configured on your smartphone.
