Resource Monitoring

Provides visualization dashboards for hosts, middleware, Kubernetes clusters, and other targets. The left submenu is generated dynamically from enabled types in Data Sources. Enabling a data source type displays the corresponding dashboard.

Submenus

Submenu	Data Source
Host	node_exporter
MySQL	mysqld_exporter
MongoDB	mongodb_exporter
Redis	redis_exporter
Kafka	kafka_exporter
Elasticsearch	elasticsearch_exporter
Kubernetes	kube-state-metrics/kubelet. See Kubernetes Cluster Monitoring
Flink	Flink Web UI (reverse proxy)

Host Monitoring

The "Host" page summarizes resource status for all hosts. The top section is a resource detail table for all hosts (CPU/memory/load/disk/partition usage, zombie processes, health score, and more). The lower section expands time-series details for CPU, memory, disk, and network by host. Click a host IP to drill down into the full host dashboard.

Middleware Monitoring

Each middleware type has a dedicated dashboard. Use the "Instance" dropdown at the top to switch among multiple instances of the same type.

MongoDB

Runtime duration, QPS, latency, replica set role, command operations, connections, query efficiency, and more. The top contains "Monitoring" and "Slow Query" tabs. The slow query tab links to MongoDB Slow Query Analysis.

MySQL

Uptime, QPS, connections, InnoDB buffer pool, client thread activity, command statistics, and more.

Redis

Uptime, connections, memory usage, command execution/hit rate, network I/O, key counts by DB, and more.

Kafka

Message production/consumption rate, consumer group lag, topic partition distribution, and more.

Elasticsearch

Cluster health, shard status, node CPU/JVM heap memory, disk and network, document indexing rate, and more.

Dashboard Operations

Resource monitoring dashboards are embedded from Grafana. Common operations:

• Instance selector: Switch among multiple instances of the same type from the Instance dropdown in the upper-left corner.
• Time range: Switch the time window in the upper-right corner (default: last 3 hours/30 minutes). Custom ranges and auto-refresh are supported.
• Expand/collapse: Click group row titles in the dashboard to expand or collapse them.

tip

Dashboard content is in English. Grafana custom panel text does not change with the platform language, so English is used consistently across languages. Panel titles, legends, and metric labels do not affect the data itself.

Kubernetes and Flink

Kubernetes: Monitors cluster nodes, containers, Pods, and cluster object status (node resources, namespaces, CPU/memory quotas, Pod distribution, and more). Configure collection according to Kubernetes Cluster Monitoring.

Flink: After the Flink entry is enabled, the Ops Platform embeds the native Flink Web UI through a dynamic reverse proxy. No additional port exposure is required.
