title: Facing trouble with Sphinx Indexer Update
body: <p>I have sphinx (version Sphinx 2.0.5-release ) running on my server. 
  Recently faced a problem with indexing. 
  I have a cron set which runs every 2 hours and rotates indexers. 
  The problem was my Database Fields got the updated data. But their corresponding indexers failed to get the updated data. My sphinx was running and not stopped. </p>
  
  <p>Is there any way to check if the indexer is updated ? Or the time it was last updated ? So that I can notify myself after every indexer rotation that the indexer is updated perfectly ? </p>
