Monitoring Dashboard

Data Refresh

Shoreline periodically ingests all of the Resource data collected by Agents. The Monitoring UI displays the aggregated Resource data.

  • Real time: Data is actively pulled from active Agents.
  • Recent: Recently gathered data. This mode is less resource-intensive as aggregated data is only pushed from Agents every few minutes, rather than in real-time.

Dimensions

op>
host | .pod

Use Dimensions to adjust the resource specificity within the view. Click a Dimension to drill up or down with options such as Region, AZ, Host Name, App, and Name Space.

dimensions

  • Click on a Dimension + sign to enable it.
  • Alternatively, click a Dimension - sign to disable it.
  • Enabling Dimensions loads charts automatically for all filtered resources.

Aggregation

Anytime you are viewing combined Dimensions the displayed resource charts are automatically aggregated. Averaging is the default operation used by data aggregation.

For example, here we're viewing both the Region and AZ Dimensions, but not the Host Name. We have (2) hosts within the us-east-1b AZ, so the us-east-1b chart shows the number of hosts and automatically aggregates data within that AZ:

Step-by-Step Instructions

Monitor by Dimensions

Dimensions are how you drill up or drill down

Monitor by Time Period

You can view alarms for a specific time period

  1. Click on the drop-down arrow next to Period
  2. Select Last 7 days, Last 24 hours, Last 60 minutes, or Last 10 minutes
  3. To define your own time period, click on Custom
  4. Select the Start and End dates and times and click Apply

Shoreline supports per second metrics and, depending on the selected period, there is an automatic rollup performed to provide you the correct data points. For example:

  • 10 minutes gives you 600 data points
  • For Last 60 minutes, you get what is called a 10-second resolution. That means that (10) 1-second metrics are aggregated to create a single data point for a 10-second window. That calculates to 6 data points per minute and 360 data points for the hour.
  • For Last 24 hours, the resolution is 1 minute
  • For Last 7 days, the resolution is 1 hour

Refreshing Data

You can refresh data automatically or manually

  1. Click on the drop down arrow next to Refresh
  2. To refresh automatically, select Recent or Real time (which is the most up to date)
  3. Select the refresh Frequency - every 1, 5, 10, 30 seconds, or 1 minute
  4. To refresh manually, select Manual under Refresh every
  5. Click on the Refresh button
  6. A timestamp of the last refresh is displayed next to the Refresh button
