Utilization Metrics

Metrics refer to the availability of resources such as vCPU, memory, disk, RAM, etc. The MobiledgeX platform collects metrics for the following components.

  • Cluster Instances

  • Application Instances

Collecting resource metrics is useful if you use them in conjunction with alerts that can help you identify issues and quickly respond to them. For example, you can set alerts and be notified when you have exceeded the threshold for vCPU. Metric information can also be useful when you want to understand the utilization of your resources to determine the percentage of your resource's capacity that is in use and whether to increase them based on user demand.

Monitoring Dashboard

From the Edge-Cloud Console UI, select Monitoring from the left navigation. The Monitoring page opens. Make sure that you are managing the Organization that you wish to view metrics information.

The MobiledgeX Edge-Cloud Console provides a Monitoring Dashboard to help you visually centralize, collect, aggregate, and analyze events so that you can get a bigger picture of what is going on across your infrastructure in real-time. Within a single pane of glass and a customizable UI to enlarge your view and change the graphic representation of your data, you can view both current and historical data, log and analyze pattern usages and trends to make informed decisions about your infrastructure to help your users get the most out of your services offered.

Filtering

The Monitoring Dashboard provides many ways to filter the data you need to view and access. You can view by organization, regions, metric types, app instance, cluster instance or cloudlet, and search by admins, developers, or operators. You can also filter by time ranges. While the maximum allocated days you can search for audit logs is one day (within the last 24hrs), you can further refine your search for logs with the span of the 24 hour period. Start time default is 12:00a.m. and End Time default is 11:59p.m.

You can also refresh your data and specify your refresh rate by seconds, minutes, or hours. You will see a progress bar at the top of the page which serves as an indicator. Click the eye icon to customize your view and include specific metrics information.

Monitoring Metrics Window

You may find the following information displayed on your Monitoring Dashboard:

  • Cluster level resource utilization, performance, and status metrics

  • Load balancer (Layer 4) metrics and status

  • Application Instance resource utilization, performance, and status metrics

  • Application Instance event logs, showing state changes and other Application Instance events

  • Distributed Matching Engine (DME) metrics, including location-based metrics for remote users
