Bases: [`Source`](https://docs.pip.distribution.sol.onetick.com/api/source/root.html.md#onetick.py.Source)

Shows description for requested event processor searching all accessible tick servers.

* **Parameters:**
  * **ep_name** ([*str*](https://docs.pip.distribution.sol.onetick.com/api/operation/str/root.html.md#onetick.py.Operation.str)) -- Event processor name to retrieve description for.
  * **prefer_local_info** ([*bool*](https://docs.python.org/3/builtins/functions.html#bool)) -- If set to True and local description is present,
    no attempt is performed to retrieve description from accessible tick servers.
    Default is False.
  * **symbol** ([*str*](https://docs.pip.distribution.sol.onetick.com/api/operation/str/root.html.md#onetick.py.Operation.str)) -- Bound symbol on the node of the graph.
    Not set by default -- the value from [`otp.run`](https://docs.pip.distribution.sol.onetick.com/api/run.html.md#onetick.py.run) will be used.
  * **tick_type** ([*str*](https://docs.pip.distribution.sol.onetick.com/api/operation/str/root.html.md#onetick.py.Operation.str)) -- Tick type set on the node of the graph.
    Not set by default.
  * **start** ([`datetime.datetime`](https://docs.python.org/3/library/datetime.html#datetime.datetime), [`otp.datetime`](https://docs.pip.distribution.sol.onetick.com/api/datetime/dt.html.md#onetick.py.datetime)) -- Time interval from which the data should be taken.
    Not set by default -- the values from [`otp.run`](https://docs.pip.distribution.sol.onetick.com/api/run.html.md#onetick.py.run) will be used.
  * **end** ([`datetime.datetime`](https://docs.python.org/3/library/datetime.html#datetime.datetime), [`otp.datetime`](https://docs.pip.distribution.sol.onetick.com/api/datetime/dt.html.md#onetick.py.datetime)) -- Time interval from which the data should be taken.
    Not set by default -- the values from [`otp.run`](https://docs.pip.distribution.sol.onetick.com/api/run.html.md#onetick.py.run) will be used.
  * **query_parameters** ([`otp.QueryParameters`](https://docs.pip.distribution.sol.onetick.com/api/misc/query_parameters.html.md#onetick.py.QueryParameters)) -- Additional query properties to be set in the resulting .otq file.
    They will be used if they are not overridden by other parameters or in [`otp.run`](https://docs.pip.distribution.sol.onetick.com/api/run.html.md#onetick.py.run).
