euserv-describe-events [-s] [-f FORMAT]


Events come in the form of a list, where each event contains one or more of the following tags:

Tag Description
id A unique ID for the event.
message A free-form text description of the event.
severity The message’s severity (FATAL, URGENT, ERROR, WARNING, INFO, DEBUG, TRACE).
stack-trace The stack trace, if any, corresponding to the event. The -s option is required to make this appear.
subject-arn The Eucalyptus ARN of the service affected by the event.
subject-name The name of the service affected by the event.
subject-type The type of service affected by the event.
timestamp The date and time of the event’s creation.


The command requires access keys and knowledge of where to locate the web services it needs to contact. It can obtain these from several locations.

Environment Description
AWS_ACCESS_KEY_ID The access key ID to use when authenticating web service requests. This takes precedence over and euca2ools.ini, but not -I.
AWS_SECRET_ACCESS_KEY The secret key to use when authenticating web service requests. This takes precedence over –region and euca2ools.ini(5), but not -S.
EUCA_BOOTSTRAP_URL The URL of the service to contact. This takes precedence over –region and euca2ools.ini, but not -U.


Option Description Required
-f, –format format Print events in a given format, where format can be: yaml or oneline, and format:string. See for details about each format. When omitted, the format defaults to yaml. No
-s, –show-stack-traces Include the stack-trace tag in events’ data. This is omitted by default due to its length. No


There are several built-in formats, and you can define additional formats using a format: string , as described below. Here are the details of the built-in formats:

yaml This outputs block-style YAML designed to be easily readable. Tags that are empty or not defined do not appear in this output at all.

            - timestamp: {timestamp}
            severity: {severity}
            id: {id}
            subject-type: {subject-type}
            subject-name: {subject-name}
            subject-host: {subject-host}
            subject-arn: {subject-arn}
            message: |-
            stack-trace: |-

oneline This output is designed to be as compact as possible.

{timestamp} {severity} {subject-type} {subject-name} {message}

format:string The format: string format allows you to specify which information you want to show using placeholders enclosed in curly braces to indicate where to show the tags for each event. For example:

euserv-describe-events -f "format:{timestamp} {subject-name} {message}"


To output a list of service-affecting events in the oneline format:

euserv-describe-events --format oneline
