Technologies are generally described for systems and methods to identify defective segments of content data. The methods may comprise generating a monitor agent effective to generate a request for the content data. The methods may comprise deploying the monitor agent to an address. The monitor agent may be effective to extract the content data and to generate delivery data associated with the content data. The methods may comprise distributing the delivery data to a parameter processor. The methods may comprise generating parameter data. The parameter data may be effective to indicate a parameter level associated with a parameter of the content data. The methods may comprise generating performance data based on the parameter data. The performance data may be effective to indicate a number of defects among the content data. The methods may comprise identifying a number of defective segments among the content data based on the performance data.
