–color=<string>

Colorize output. Possible values are:

• auto: guess based on tty presence

–local

Execute the service action on the local service instances only, ignoring cluster-wide considerations.

–namespace=<string>

The namespace to switch to for the action. Namespaces are cluster partitions. A default namespace can be set for the session setting the OSVC_NAMESPACE environment variable.

–node=<string>

The node to send a request to. If not specified the local node is targeted.

–rid=<string>

A resource specifier expression like <spec>[,<spec>], where <spec> can be:

• A resource id

• A driver group name (app, fs, disk, …)

Examples:

• app all app resources

• container#1,ip#1 only container#1 and ip#1

–status=<string>

Operate only on service with a local instance in the specified availability status (up, down, warn, …).

–subsets=<string>

Limit the action to the resources in the specified, comma-separated, list of subsets.

–tags=<string>

A comma-separated list of resource tags to limit action to. The + separator can be used to impose multiple tag conditions. For example, tag1+tag2,tag3 limits the action to resources with both tag1 and tag2, or tag3.

–waitlock=<string>

A duration expression like 5s. The maximum wait time when acquiring the service action lock.

-h, –help

-p, –parallel

Start actions on specified services in parallel. max_parallel in node.conf limits the number of parallel running subprocesses.

-s, VAL, –service=<string>

A service selector expression [!]<expr>[<sep>[!]<expr>] where:

• ! is the expression negation operator

• <sep> can be:

  • , OR expressions

  • + AND expressions

• <expr> can be:

  • a shell glob on service names

  • <param><op><value> where:

    • <param> can be:

      • <rid>:

      • <group>:

      • <rid>.<key>

      • <group>.<key>

      • <single value jsonpath expression on the $.monitor.services.<path> dictionary extended under the 'nodes' key by each instance 'status' and 'config' data>

    • <op> can be:

      • < > <= >= =

      • ~ the string or any list element matches the regexp value

      • ~= the string matches regexp value or any list element is the value

Examples:

• *dns,ha*+app.timeout>1

• ip:+task:

• !*excluded

• $.avail=warn

• $.nodes.*.status.avail=warn

Note:

• ! usage requires single quoting the expression to prevent shell history expansion
