Verify the Services

This topic describes how to verify all the services after upgrading.

Verify that all Eucalyptus components are running and properly connected to one another. Check to make sure that the status of each service is enabled.

To verify that all services are enabled:

Verify the Eucalyptus versions. For example:

# euca-version
euca2ools 3.4.1
eucalyptus 4.4.4

If you are using the Walrus backend for object storage, verify your Walrus backend service:
```
euserv-describe-services --filter service-type=walrusbackend
```
Eucalyptus returns a result, as in the following example.
```
SERVICE walrusbackend walrus enabled
```

Verify your CCs:

euserv-describe-services --filter service-type=cluster

Eucalyptus returns a list, as in the following example.

SERVICE cluster one one-cc enabled
SERVICE cluster two two-cc enabled

Verify your SCs:

euserv-describe-services --filter service-type=storage

Eucalyptus returns a list, as in the following example.

SERVICE storage one one-sc enabled
SERVICE storage one one-sc enabled

Make sure that NCs are presenting available resources to the CC.

euca-describe-availability-zones verbose

The returned output should a non-zero number in the free and max columns, as in the following example.
