How to analyze the Prometheus and Grafana function analysis of CDSW, aiming at this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Purpose of document writing

Prometheus + Grafana is introduced in CDSW1.7 and later versions to provide a visual Dashboard to monitor how each Pod in CDSW uses the cluster's CPU/GPU, memory, and storage resources. Prometheus is an internal timing data source that automatically records the usage data of each deployment resource in CDSW. Grafana is a visual monitoring dashboard that allows you to customize your own monitoring charts. CDSW has provided 3 Grafana Dashboards:K8 Cluster,K8s Container and K8 Node by default, and more custom monitoring charts can be created through the basic monitoring dashboard provided. This document describes how to view and use Grafana.

Test environment

1.CDSW1.7.2

Function introduction and use

2.1 Grafana monitoring interface

1. Log in to CDSW using the administrator, go to the "Admin" > "Overview" page, and then click the link to jump to

The 2.Grafana home page is as follows:

3. Click Home in the upper left corner and you can see the three dashboards provided by Grafana by default:

2.2 K8s Containers Dashboard

Enter the Dashboard interface of K8s Containers. The monitoring chart mainly provides all the Pods monitoring information initiated in the CDSW cluster (resource usage of each pod).

Memory and CPU used by Pods:

The CPU graph used by Pods and the CPU used by each process:

The memory graph used by Pods and the memory used by each process:

The network IO graph used by Pods and the network IO used by each process

View the resource usage of a single pod (can correspond to the Session started by CDSW)

2.3 K8s Node Dashboard

Enter the Dashboard interface of K8s Node. The monitoring dashboard mainly provides monitoring of the resource usage of all Node nodes in the CDSW cluster (which can be understood as server-level resource usage monitoring), including CPU, memory, disk, network, etc.

2.4 K8s Cluster Dashboard

Enter the Dashboard interface of K8s Cluster, which mainly provides monitoring of resource usage at all NameSpace levels of K8s Cluster (you can see resource usage at user level through this Dashboard)

Specify Namespace (default-user- {userid} this type of Namespace is user-level monitoring)

2.5 Custom Dashboard

1. Create a custom Dashboard

two。 Choose to create a chart of type Graph

3. Select Edit

4. Enter the chart editing interface, select the data source and enter the query statement to complete the construction of the chart.

5. Click the save button in the upper right corner to save the built chart to the custom Dashboard.

Grafana, a new feature of 1.CDSW1.7.x, can well monitor the use of resources on CDSW, including system services and user usage.

2.Grafana supports the configuration of alarms, which can be configured for the dashboard. Alarms will be triggered when the threshold is triggered.

3. In addition to the default Dashboard provided by the system, you can also customize the metrics you want to monitor and convert them into charts through PromQL statements.

This is the answer to the question on how to parse CDSW's Prometheus and Grafana function analysis. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
