I have subscribed my server to my Youtube channel via youtube PubSubHubbub. I am experiencing delay in notifications sometimes.
Is there anyway ( like statistics, tracking, youtube API ) by which I can know, when the PubSubHubbub event is fired, so that I can actually know, if there is a delay?.
The atom feed looks like this:
<entry>
<id>yt:video:vidxxx</id>
<yt:videoId>videxxx</yt:videoId>
<yt:channelId>channelxxx</yt:channelId>
<title> titlexxx</title>
<link rel="alternate" href="https://www.youtube.com/watch?v=vidxxx"/>
