StorageTask

The StorageTask can be used to monitor one or more storage changes on chain. It's identifier is system.storage.

Arguments

StorageTask takes the argument name of type string or string[] for monitoring multiple storages.

name takes the form of <pallet>.<storage>.

StorageTask also takes an optional argument args of type any | any[] as the arguments to pass to the storage query.

For example:

...
task: system.storage
arguments: 
    name: identity.identityOf

    args:
        - 5HmWP5WF24fchkiTqJPn5q2nrgFf3VD81LfdU7KRJLPve3fj # some address
...

Since identity.identityOf requires an account address as an argument we must supply it to args.

For storages that don't require any arguments it can be ommited, for example:

...
task: system.storage
arguments:
    name: system.number
...

Output

The output for this task will be in the following format:

{
  "name": string, // The name of the storage query
  "value": any // The value returned from the query
}
