data collection is not starting, it status is idle always.I'm posting the ani.log please find it.
There is no obvious error here, but you may be seeing a problem where Data Collection dies due to a NullPointerException. The fix is to upgrade to CM 5.0.4. You can get this under Common Services > Software Center > Software Update. If, after upgrading, you still see the problem, post the ANIServer.log.
