Media stream monitoring includes initiating, by a processing device, a media-stream-monitoring-application configured to monitor a plurality of media streams including packetized media content. A plurality of media stream records associated with the plurality of media streams are obtained. The media stream records include addresses used to connect to the plurality of media streams The media-stream-monitoring-application attempts to connect to a first media stream associated with a first media stream record, wherein connecting to the first media stream includes requesting a sample packet from the address associated with the first media stream. An error associated with the sample packet is identified. At least in part based on identifying the error associated with the sample packet: disconnecting from first media stream; generating an error report; and discarding the first media stream record.
