Method from org.apache.geronimo.monitoring.snapshot.SnapshotDBHelper Detail:
 public boolean addSnapshotToDB(HashMap<String, Long> aggregateStats) 
 public ArrayList<String, Object> fetchData(Integer numberOfSnapshot,
    Integer everyNthSnapshot) 
    Fetches the data stored from the snapshot thread and returns it in a ArrayList with each element being a HashMap of the attribute mapping to the statistic. Grabs 'numberOfSnapshots' snapshots. Grabs one snapshot per 'everyNthsnapshot'

 public HashMap<String, Long> fetchMinSnapshotData(Integer numberOfSnapshots) 
 public HashMap<String> getAllSnapshotStatAttributes() 
 public Long getSnapshotCount() 
 public TreeMap<Long, Long> getSpecificStatistics(String mbeanName,
    String statsName,
    int numberOfSnapshots,
    int everyNthSnapshot,
    boolean showArchived) 
 public String prepareInsertSnapshotStatement(String snapshot_time,
    String statsValueList,
    int mbeanId) 
 public  void setDataSources(DataSource active,
    DataSource archive) 
    Sets the necessary data sources for this helper to talk to the db
