Abstract: In order to support regular operations, the Chandra Data Archive Operations Group has developed a database that records and monitors the user activities that affect the archive servers. This database provides information on the number of users that are connected at a given time, what archive interfaces they use (we have several), and how much and what type of data is being downloaded. The database consists of three tables populated by a set of four scripts that parse the archive server logs, the ftp logs and the login logs. User activity can be tracked through each of those logs, making information from a given connection easily accessible. With this tool, the Archive Operations Group will be able to gather statistics and monitor trends, which will improve the accessibility of Chandra data.
