Zenoss Control Center

The information that Control Center needs to start and manage a service, in JavaScript Object Notation (JSON) format.

Note: Most values may contain Go templates, with Control Center functions. For more information, see Go templates in JSON values.

Atttribute	Value	Description
`Name`	String	The service name.
`Command`	String	The command that starts and runs the service.
`Description`	String	The service description.
`Tags`	Array of strings	Searchable words or phrases for the service.
`ImageID`	String	The Docker image ID for the service.
`Instances`	Object	The number of instances of the service to run at the same time, in different containers. This object has two members. `Min` The minimum number of instances to run. If the value is zero, no instances are started. If non-zero, the value must be greater than or equal to zero. `Max` The maximum number of instances to run. If the value is zero, only `Min` is used. If non-zero, the value must be greater than or equal to `Min`.
`ChangeOptions`	Array of strings	Control options for what happens when a running instance of the service is changed.
`Launch`	String	Determines whether the service starts when its parent service starts. `AUTO` (Default) Start the service when the parent service starts. `MANUAL` Do not start the service when the parent service starts.
`HostPolicy`	String	Determines how to schedule instances of the service on hosts in a resource pool. `LEAST_COMMITTED` (Default) Select the host with the smallest amount of memory committed to other services. `PREFER_SEPARATE` Attempt to schedule instances of the service on separate hosts. `REQUIRE_SEPARATE` Schedule instances of the service on separate hosts only.
`Hostname`	String	The virtual host name to use when an instance of the service is run.
`Privileged`	`true` or `false`	Determines whether containers (in which instances of the service run) have extended privileges.
`ConfigFiles`	Objects	The configuration file templates to install in containers (in which instances of the service run). Each member of this object is a string containing the absolute path of a configuration file template and a ConfigFile object.
`Context`	Object
`Endpoints`	Array of objects	The network endpoints that the service uses, as Endpoint objects.
`Services`	Array of objects	The subservices that are part of the service, as ServiceDefinition objects.
`Tasks`	Array of objects
`LogFilters`	Object	Pairs of strings and values mapping log filter names to log filter definitions.
`Volumes`	Array of objects	The list of file system directories to bind mount in containers (in which instances of the service run). Each item is a Volume object.
`LogConfigs`	Array of objects	A list of logstash configurations for the log files of the service, as LogConfig objects.
`Snapshot`	Object	The bash commands to pause and resume the service. Between commands, Control Center copies the file system of the service's container. This object has two members: `Pause` The bash command to stop file system writes, or stop the service. `Resume` The bash command to return the service to normal processing.
`RAMCommitment`	Integer	The amount of main memory the service requires, in bytes. This value is used to help schedule the service into the best available resource pool.
`CPUCommitment`	Integer	The number of CPU cores the service requires. This value is used to help schedule the service into the best available resource pool.
`Runs`	Object	The commands the service executes inside its container when invoked with `serviced run Command`. This object contains one or more command names, each paired with the bash command to run inside the containers.
`Actions`	Object	The commands the service executes inside its container when invoked with `serviced action Command`. This object contains one or more command names, each paired with the bash command to run inside the containers.
`HealthChecks`	Object	The commands to invoke (at regular intervals) to gather data about health of the service. Each member of this object is a health check name paired with a HealthCheck object.
`Prereqs`	Array of objects	The scripts to run successfully inside a container before starting the service in the container. Each item is an object with two members: `Name` The name of the prerequisite. `Script` The bash command to invoke inside the container.
`MonitoringProfile`	Object	Metadata descriptions of the metrics, graphs, and thresholds the service makes available to external monitoring services. The members of this object are the following pairs, in order: `MetricConfigs` An array of MetricConfig objects. `GraphConfigs` An array of GraphConfig objects. `ThresholdConfigs` An array of ThresholdConfig objects.
`MemoryLimit`	float64
`CPUShares`	int64
`PIDFile`	String	The path, or the command to generate the path, for the PID file to which signals are copied.
