Using the OpCenter Web Interface

OpCenter provides a web interface to submit, manage, and view jobs.

Accessing the OpCenterWeb Interface

  • Open a browser and go to the IP address (public if you are outside the VPC, private if you are inside the VPC) associated with your OpCenter. The landing page allows you to do the following.
    • See the version of software installed
    • Check the status of the license associated with this OpCenter
    • Log in to OpCenter
    • Download the CLI tool for your local operating system (Windows, Linux or macOS)
  • Log in to the OpCenter by entering your username and password, and then clicking on the Log In button.

    The first time you log in, use the default username and password of admin and memverge, respectively. After you log in, you can change the admin password.

Navigating the OpCenter Web Interface

The left-hand panel displays the available screens. The following screens are available.
  • Submit Job
  • Cost Summary
  • Jobs
  • Images
At the top, right-hand side are a series of icons that allow you to perform the following actions.
  • Return to the landing page
  • Open the web CLI console
  • Access documentation at docs.memverge.com
  • Log out of the OpCenter

Submit Job Screen

On the left-hand side of the Submit Job screen, you can fill in the fields (some mandatory) in a form and then submit a job. The right-hand side shows the equivalent CLI commands. To submit a job, click on the Submit button at the bottom, on the right.

Cost Summary Screen

The Cost Summary screen summarizes your cloud spending in a single dashboard. View cloud costs and savings by week, month, year, application, or user.

When you instantiate a VM, the CSP begins charging (in one second increments) for the compute instance and any storage devices you configure. You must configure disk space for the root volume (where the operating system is stored) and normally you configure additional disk space for your data (the data volume). VMs instantiated by OpCenter include two additional disk volumes: the image volume (to store the container image) and the snapshot volume (to store snapshots).

The default size for the root volume is 40 GB. If this volume is used for an entire month, the charge would be about USD 4.

Cloud cost for a single job is calculated as follows.

Cloud cost = Instance cost + data volume cost + image volume cost + snapshot volume cost

where the Instance can be an On-demand Instance or a Spot Instance. The root volume cost is not included.

Net savings is calculated by comparing what the cost would be if the job were run on an On-demand Instance, not using OpCenter, with the Cloud Cost. That is,

Net savings = On-demand cost - Actual instance cost - image volume cost - snapshot volume cost

Cloud Cost and Net Savings for each job are aggregated to arrive at the numbers reported per week, per month, etc.

Jobs Screen

Using the Jobs screen, you can view and manage current jobs, and you can view archived jobs. You can search for jobs and filter the displayed results. Click on a job to display detailed information about the job, including logs and graphs of resource utilization over time.

To migrate, modify or cancel a currently running job, identify the job by ID or by name. In the Actions column are three icons corresponding to migrate, modify, and cancel, respectively. Clicking on an icon brings up a dialog box. Fill in the dialog box to complete the action.

To view the logs associated with a current or archived job, click on the job ID. In the table that is displayed, click on Attachments to list the logs associated with the job. Click on the Preview icon to view the contents of a log.

Images Screen

The Images screen shows the container images that are currently loaded in to the OpCenter image library. The display shows images that are automatically loaded as well as images that you add. To add an image, go to the Private tab and click on Add Image.

Images with the status listed as Ready are currently loaded in to the OpCenter's image cache.
