zabbix-kubernetes-monitoring is zabbix-agent script and template for zabbix server. It is used for Kubernetes monitoring by Zabbix. Easy to deploy and configure. Auto discovery of pods, deployments, services, etc.
- Copy
k8s-stats.pyto /usr/lib/zabbix/externalscripts andk8s-stats.jsonto /etc/zabbix/ and fix file permissions
cp k8s-stats.py /usr/lib/zabbix/externalscripts/
cp k8s-stats.json /etc/zabbix/
chmod +x /usr/lib/zabbix/externalscripts/k8s-stats.py
chown zabbix. /etc/zabbix/k8s-stats.json
chmod 640 /etc/zabbix/k8s-stats.json
- Import Zabbix template
k8s-zabbix-template.xmlto Zabbix server - Create zabbix user in Kubernetes (can use
zabbix-user-example.yml) and set it's token and API server url ink8s-stats.json. The root item key names in JSON config refer to - Apply template to host
{$K8S_CLUSTER_NAME}macro value in zabbix configuration, see step 5. - Update
{$K8S_CLUSTER_NAME}macro value appropriately in host configuration. Example:
{
"my-cloud-123": {
"api_url": "https://my_cloud_address:6443",
"access_token": "my_cloud_token"
}
}You then need to use {$K8S_CLUSTER_NAME} => my-cloud-123 on zabbix host you have attached the template to
Simply add more dicts to k8s_stats.json. Sample config file provided in repo has two clusters added.
