通过监控异常的pod，及时发现k8s存在的问题。原理是使用kubectl get pod –all-namespaces，找到ready列，如果ready数量与desire数量不一致的，或者非RUNNING的状态POD,则认为这个pod异常，，进而告警。

配置agent监控项

/etc/zabbix/zabbix_agentd.d/k8s.conf

UserParameter=abnormal.pod, kubectl get pod --all-namespaces -o wide | awk 'NR>1{cmd="echo "$3" | bc";cmd|getline ret;close(cmd);if (ret != 1 || $4 != "Running"){print}}'
