Mackerel supports obtaining and monitoring App Engine metrics with Google Cloud Integration. When integrating with Google Cloud Integration, billable targets are determined using the conversion 1 Version = 1 Micro Host. In addition to this, depending on the number of metrics retrieved, you may be charged for exceeding the maximum number of metrics per micro host.
Please refer to the following page for Google Cloud Integration configuration methods and a list of supported services.
Google Cloud Integration
Required API
The following API must be enabled in order to integrate App Engine.
- App Engine Admin API(appengine.googleapis.com)
Required role
The following role is required for the service account in order integrate App Engine.
- App Engine Viewer (roles/appengine.appViewer)
Obtaining metrics
The metrics obtainable with Google Cloud Integration’s App Engine support are as follows. For Metric explanations, refer to the Google Cloud documentation.
Standard environments
The maximum number of metrics obtainable is 13 + 4 × [Response code].

Memcache
In addition to those above, the following metrics are acquired when using Memcache with the 1st generation App Engine.
The maximum number of obtainable metrics is 5 × [command name]
| Graph name | Index type | Metric name in Mackerel | Unit |
|---|---|---|---|
| Memcache utilization | memcache/centi_mcu_count | appengine.memcache.[command name].centi_mcu_count.count | integer |

Notes
- Due to the specifications of App Engine, App Engine hosts cannot be filtered by label in Google Cloud Integration.
