Compare profiles

Cloud Profiler lets you visually compare two profiles of the same type, taken from the same service within a project. You can compare profiles that differ by:

• Ending times: Does the service run faster at certain times? Has there been a gradual improvement or decline over time?
• Zones: Does the service run faster in some zones than in others?
• Service versions: Do newer versions differ markedly from older ones? How?
• Weight: How do profiles captured during high consumption periods differ from average profiles?

Setting up a comparison

When you set up a comparison, you specify the parameters for an original profile and a compared profile. These two profiles share all configuration parameters except the one defined by the Compare to field.

To configure a comparison, do the following:

1. Set the comparison type by selecting an option from the Compare to menu:

   • End date/time
   • Zone
   • Version
   • Weight

   Selecting one of these options results in a new configuration field. The field name begins with Compared and ends with the comparison type. For example, if you select Version, a Compared version field is displayed next to the Compare to field.

2. Specify the compared profile by selecting an option from the Compared menu.

For example, the screenshot illustrates the settings to compare two versions of docdemo-service:

The settings for the following fields apply to the original profile and the compared profile:

• Timespan: 7 days
• End time:
