POD资源历史曲线（CPU、内存、网络）
监控方案heapster+hawkular-metrics+hawkular-cassandra
heapster负责收集数据
hawkular-cassandra 存储数据
hawkular-metrics 展示数据
部署方案
修改/etc/ansible/hosts添加一下内容
这里要注意看要不要持久化
[OSEv3:vars]
openshift_metrics_install_metrics=true
openshift_metrics_cassandra_storage_class_name=gluster-storag
openshift_metrics_cassandra_storage_type=dynamic
openshift_metrics_cassandra_pvc_size=20Gi
openshift_metrics_cassandra_limits_memory=2Gi
openshift_metrics_cassandra_requests_memory=1Gi
openshift_metrics_cassandra_limits_cpu=500m
openshift_metrics_cassandra_requests_cpu=200m
openshift_metrics_hawkular_limits_cpu=500m
openshift_metrics_hawkular_requests_cpu=200m
openshift_metrics_hawkular_requests_memory=1Gi
openshift_metrics_hawkular_limits_memory=2Gi
openshift_metrics_heapster_limits_memory=256Mi
openshift_metrics_heapster_limits_cpu=200m
openshift_metrics_heapster_requests_memory=128Mi
openshift_metrics_heapster_requests_cpu=50m
openshift_metrics_duration=
openshift_metrics_resolution=30s
运行部署
# ansible-playbook openshift-ansible/playbooks/openshift-metrics/config.yml
查看有没有部署成功
# oc project openshift-metrics
# oc get pod
运行完之后登陆web console 找个pod点开Metrics
集群资源展示
监控方案 prometheus + grafana
prometheus收集集群数据
grafana 负责集群展示
部署prometheus+grafana
修改/etc/ansible/hosts添加一下内容
[OSEv3:vars]
openshift_cluster_monitoring_operator_install=true
openshift_cluster_monitoring_operator_prometheus_storage_enabled=true
openshift_cluster_monitoring_operator_prometheus_storage_capacity=
openshift_cluster_monitoring_operator_prometheus_storage_class_name=gluster-storag
运行部署
# ansible-playbook openshift-ansible/playbooks/openshift-prometheus/config.yml
# ansible-playbook openshift-ansible/playbooks/openshift-glusterfs/config.yml
查看有没有部署成功
# oc project openshift-metrics
# oc get pod
打开控制台开始配置
http://prometheus-openshift-metrics.oc.downtown8.com/
http://grafana-openshift-metrics.oc.downtown8.com/
prometheus基本不用配置安装程序已经跟k8s对接好了
主要是配置一下grafana的k8s插件
初步的效果
集群内存
集群CPU
集群网络
