Subscribing to module report events

# Copy the following message to the client to complete the subscription:

<?xml version="1.0" encoding="UTF-8"?>
<rpc message-id="100" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:xs="http://www.hp.com/netconf/base:1.0">
<create-subscription xmlns="urn:ietf:params:xml:ns:netconf:notification:1.0">    
<stream>XXX_STREAM</stream>
   <filter type="subtree">
<event xmlns="http://www.hp.com/netconf/event:1.0/xxx-features-list-name:1.0">
       <ColumnName xs:condition="Condition">value</ColumnName>
</event>
</filter>
<startTime>start-time</startTime>
<stopTime>stop-time</stopTime>
</create-subscription>
</rpc>

The <stream> parameter represents the event stream. The name for the module notification event stream varies by actual condition.

The event parameter represents the event name. An event stream includes multiple events. The namespace of the event is the namespace of the event stream.

The ColumnName parameter represents the name of the column to be filtered in the current event.

The Condition parameter represents the filter condition. The options are described in Table 11. Choose the filter condition according to the type of the baseline value.

The value parameter represents the baseline value for the column.

The <start-time> parameter represents the start time of the subscription.

The <stop-time> parameter represents the end time of the subscription.

After receiving the subscription request from the client, the device returns a response in the following format if the subscription is successful:

<?xml version="1.0" encoding="UTF-8"?>
<rpc-reply message-id="100" xmlns:netconf="urn:ietf:params:xml:ns:netconf:base:1.0">
    <ok/>
</rpc-reply>
