+title: "SkyWalking 10 Release: Service Hierarchy, Kubernetes Network
Monitoring by eBPF, BanyanDB, and More"
+date: 2024-5-13
+author: Kai Wan, Sheng Wu. tetrate.io
+description: "Introduce what's new in SkyWalking 10, including Service
Hierarchy, Kubernetes Network Monitoring by eBPF, BanyanDB, and more."
+tags:

+
+## Layer and Service Hierarchy
+`Layer` concept was introduced in SkyWalking 9.0.0, it represents an abstract
framework in computer science,
+such as Operating System(OS_LINUX layer), Kubernetes(k8s layer). It organizes
services and metrics into different layers based on their roles
+and responsibilities in the system. SkyWalking provides a suite of monitoring
and diagnostic tools for each layer, but there is a gap between the layers,
+which can not easily bridge the data across different layers.
+
+In SkyWalking 10, SkyWalking provides new abilities to jump/connect across
different layers and provide a seamless monitoring experience for users.
+
+### Layer Jump
+In the topology graph, users can click on a service node to jump to the
dashboard of the service in another layer.
+The following figures show the jump from the `GENERAL` layer service topology
to the `VIRTUAL_DATABASE` service layer dashboard by clicking the topology node.
+
+Figure 1: Layer Jump</br>
+
+
+Figure 2: Layer jump Dashboard
+
+### Service Hierarchy
+SkyWalking 10 introduces a new concept called `Service Hierarchy`, which
defines the relationships of existing logically same services in various layers.
+OAP will detect the services from different layers, and try to build the
connections.
+Users can click the `Hierarchy Services` in any layer's service topology node
or service dashboard to get the `Hierarchy Topology`.
+In this topology graph, users can see the relationships between the services
in different layers and the summary of the metrics and also can jump to the
service dashboard in the layer.
+When a service occurrs performance issue, users can easily analyze the metrics
from different layers and track down the root cause:
+
+The examples of the `Service Hierarchy` relationships:
+
+1. The application `song` deployed in the Kubernetes cluster with SkyWalking
agent and Service Mesh at the same time.
+So the application `song` across the `GENERAL`, `MESH`, `MESH_DP` and
`K8S_SERVICE` layers which could be monitoring by SkyWalking,
+the `Service Hierarchy` topology as below:
+
+Figure 3: Service Hierarchy Agent With K8s Service And Mesh With K8s
Service.</br>
+</br>
+And can also have the `Service Instance Hierarchy` topology to get the single
instance status across the layers as below:
+
+Figure 4: Instance Hierarchy Agent With K8s Service(Pod)</br>
+</br>
+2. The PostgreSQL database `psql` deployed in the Kubernetes cluster and used
by the application `song`.
+So the database `psql` across the `VIRTUAL_DATABASE`, `POSTGRESQL` and
`K8S_SERVICE` layers which could be monitoring by SkyWalking,
+the `Service Hierarchy` topology as below:
+
+Figure 5: Service Hierarchy Agent(Virtual Database) With Real Database And K8s
Service
+
+For more supported layers and how to detect the relationships between services
in different layers please refer to the [Service
Hierarchy](https://skywalking.apache.org/docs/main/latest/en/concepts-and-designs/service-hierarchy/#service-hierarchy).
+how to configure the `Service Hierarchy` in SkyWalking, please refer to the
[Service Hierarchy
Configuration](https://skywalking.apache.org/docs/main/latest/en/concepts-and-designs/service-hierarchy-configuration/)
section.
+
+## [Monitoring Kubernetes Network Traffic by using
eBPF](https://skywalking.apache.org/blog/2024-03-18-monitor-kubernetes-network-by-ebpf/)
+
+In the previous version, skyWalking provides [Kubernetes (K8s) monitoring from
kube-state-metrics and
cAdvisor](https://skywalking.apache.org/docs/main/latest/en/setup/backend/backend-k8s-monitoring-metrics-cadvisor/),
+which can monitor the Kubernetes cluster status and the metrics of the
Kubernetes resources.
+
+In SkyWalking 10, by leverage [Apache SkyWalking
Rover](https://skywalking.apache.org/docs/skywalking-rover/latest/readme/)
0.6+,
+SkyWalking has the ability to monitor the Kubernetes network traffic by using
eBPF, which can collect and map access logs from applications in Kubernetes
environments.
+Through these data, SkyWalking can analyze and provide the Service Traffic,
Topology, TCP/HTTP level metrics from the Kubernetes aspect.
+
+The following figures show the Topology and TCP Dashboard of the Kubernetes
network traffic:
+
+
+Figure 6: Kubernetes Network Traffic Topology</br>
+
+
+Figure 7: Kubernetes Network Traffic TCP Dashboard</br>
+
+More details about how to monitor the Kubernetes network traffic by using
eBPF, please refer to the [Monitoring Kubernetes Network Traffic by using
eBPF](https://skywalking.apache.org/blog/2024-03-18-monitor-kubernetes-network-by-ebpf/).
+
+## BanyanDB - Native APM Database
+[BanyanDB](https://skywalking.apache.org/docs/skywalking-banyandb/latest/readme/)
0.6.0 and [BanyanDB Java
client](https://github.com/apache/skywalking-banyandb-java-client) 0.6.0 are
released with SkyWalking 10,
+As a native storage solution for SkyWalking, BanyanDB is going to be
SkyWalking's next-generation storage solution. This is recommended to use for
medium-scale deployments from 0.6 until 1.0.
+It has shown high potential performance improvement. Less than 50% CPU usage
and 50% memory usage with 40% disk volume compared to Elasticsearch in the same
scale.
+
+## Apache RocketMQ Server Monitoring
+Apache RocketMQ is an open-source distributed messaging and streaming
platform, which is widely used in various scenarios including Internet, big
data, mobile Internet, IoT, and other fields.
+SkyWalking provides a basic monitoring dashboard for RocketMQ, which includes
the following metrics:
+- Cluster Metrics: including messages produced/consumed today, total
producer/consumer TPS, producer/consumer message size, messages
produced/consumed until yesterday, max consumer latency, max commitLog disk
ratio, commitLog disk ratio, pull/send threadPool queue head wait time, topic
count, and broker count.
+- Broker Metrics: including produce/consume TPS, producer/consumer message
size.
+- Topic Metrics: including max producer/consumer message size, consumer
latency, producer/consumer TPS, producer/consumer offset, producer/consumer
message size, consumer group count, and broker count.
+
+The following figure shows the RocketMQ Cluster Metrics dashboard:
+
+Figure 8: Apache RocketMQ Server Monitoring</br>
+
+For more metrics and details about the RocketMQ monitoring, please refer to
the [Apache RocketMQ Server
Monitoring](https://skywalking.apache.org/docs/main/latest/en/setup/backend/backend-rocketmq-monitoring/),
+
+## ClickHouse Server Monitoring
+ClickHouse is an open-source column-oriented database management system that
allows generating analytical data reports in real-time, it is widely used for
online analytical processing (OLAP).
+ClickHouse monitoring provides monitoring of the metrics 、events and
asynchronous metrics of the ClickHouse server, which includes the following
parts of metrics:
+
+- Server Metrics
+- Query Metrics
+- Network Metrics
+- Insert Metrics
+- Replica Metrics
+- MergeTree Metrics
+- ZooKeeper Metrics
+- Embedded ClickHouse Keeper Metrics
+
+The following figure shows the ClickHouse Cluster Metrics dashboard:
+
+Figure 9: ClickHouse Server Monitoring</br>
+
+For more metrics and details about the ClickHouse monitoring, please refer to
the [ClickHouse Server
Monitoring](https://skywalking.apache.org/docs/main/latest/en/setup/backend/backend-clickhouse-monitoring/),
+and here is a blog that can help for a quick start [Monitoring ClickHouse
through
SkyWalking](https://skywalking.apache.org/blog/2024-03-12-monitoring-clickhouse-through-skywalking/).
+
+## Apache ActiveMQ Server Monitoring
+Apache ActiveMQ Classic is a popular and powerful open-source messaging and
integration pattern server.
+SkyWalking provides a basic monitoring dashboard for ActiveMQ, which includes
the following metrics:
+- Cluster Metrics: including memory usage, rates of write/read, and
average/max duration of write.
+- Broker Metrics: including node state, number of connections, number of
producers/consumers, and rate of write/read under the broker. Depending on the
cluster mode, one cluster may include one or more brokers.
+- Destination Metrics: including number of producers/consumers, messages in
different states, queues, and enqueue duration in a queue/topic.
+
+The following figure shows the ActiveMQ Cluster Metrics dashboard:
+
+Figure 10: Apache ActiveMQ Server Monitoring</br>
+
+For more metrics and details about the ActiveMQ monitoring, please refer to
the [Apache ActiveMQ Server
Monitoring](https://skywalking.apache.org/docs/main/latest/en/setup/backend/backend-activemq-monitoring/),
+and here is a blog that can help for a quick start [Monitoring ActiveMQ
through
SkyWalking](https://skywalking.apache.org/blog/2024-04-19-monitoring-activemq-through-skywalking/).
+
+## Support Multiple Labels Names
+Before SkyWalking 10, SkyWalking does not store the labels names in the
metrics data, which makes MQE have to use `_` as the generic label name,
+it can't query the metrics data with multiple labels names.
+
+SkyWalking 10 supports storing the labels names in the metrics data, and MQE
can query or calculate the metrics data with multiple labels names.
+For example:
+The `k8s_cluster_deployment_status` metric has labels `namespace`,
`deployment` and `status`.
+If we want to query all deployment metric value with
`namespace=skywalking-showcase` and `status=true`, we can use the following
expression:
+```text
+k8s_cluster_deployment_status{namespace='skywalking-showcase', status='true'}
+```
+
+related enhancement:
+- Since Alarm rule configuration had migrated to the MQE in SkyWalking 9.6.0,
the alarm rule also supports multiple labels names.
+- PromeQL service supports multiple labels names query.
+
+## Metrics gRPC exporter
+SkyWalking 10 enhanced the [metrics gPRC
exporter](https://skywalking.apache.org/docs/main/latest/en/setup/backend/exporter/#grpc-exporter),
+it supports exporting all type metrics data to the gRPC server.
+
+## SkyWalking Native UI Metrics Query Switch to V3 APIs
+SkyWalking Native UI metrics query deprecate the V2 APIs, and all migrated to
[V3
APIs](https://skywalking.apache.org/docs/main/latest/en/api/query-protocol/#v3-apis)
+and
[MQE](https://skywalking.apache.org/docs/main/next/en/api/metrics-query-expression/#metrics-query-expressionmqe-syntax).
+
+## Other Notable Enhancements
+1. Support Java 21 runtime and oap-java21 image for Java 21 runtime.
+2. Remove CLI(`swctl`) from the image.
+3. More MQE functions and operators supported.
+4. Enhance the native UI and improve the user experience.
+5. Several bugs and CVEs fixed.
