ZAC - Zabbix Automatic Configuration for Kubernetes

Warning events rate alerting

The rate server

zac server computes rate of events of type "Warning" in a Kubernetes cluster

It has been designed to be embedded directly inside a POD.

Do not forget to add view role to the service account :

oc adm policy add-cluster-role-to-user view system:serviceaccount:mynamespace:default

Where mynamespace is the namespace where the r8-alter pod is living.

Create Web Scenarios in Zabbix

./zac sync rates creates Web Scenarios and triggers in Zabbix

Example :

> $ NAMESPACES="default,*-dev,jenkins*" RATE_SERVICE_URL=http://192.168.99.1:8080/ ZABBIX_URL=http://localhost:8070 ZABBIX_USER=admin ZABBIX_PASSWORD=zabbix SERVICE_ACCOUNT_DIRECTORY=. KUBERNETES_SERVICE_HOST=192.168.99.100 KUBERNETES_SERVICE_PORT=8443 ./zac sync rates
==> Add or Update Zabbix web scenario and triggers
Add or update monitoring for namespace default
Add or update monitoring for namespace myproject-dev
Add or update monitoring for namespace jenkins-foo
Add or update monitoring for namespace jenkins2
