@Deprecated
public class Stats
extends Object
```
Description:
Stats is responsible for calculating the load and health of a given server. It uses tomcat's status servlet results. A schema was generated for the XML output and JAXB was used to generate classes.
The equations are:
memory weight = (int)(50 * (free/max))
thread weight = (int)(50 * (current/max))
The load factors are stored in the properties files. Simply change the values in the properties to change how load is calculated. The defaults values are memory (50) and threads (50). The sum of the factors must equal 100.

public static int calculateLoad(Status stat)
```
    Deprecated.
    
    The method is responsible for taking a status object and calculating an int value from 1 to 100. We use a combination of free memory and free threads. The current factor is 50/50.
    
    Parameters:
    stat - status information about the server
    
    Returns:
    calculated load value
  - calculateStatus
```
public static int calculateStatus(Status stat)
```
    Deprecated.
    Method should calculate if the server is: dead, active, warning or healthy. We do this by looking at the current busy threads.
    1. free > spare is healthy
    2. free < spare is active
    3. busy threads > 75% is warning
    4. none of the above is dead
    Parameters:
    stat - status information about the server
    
    Returns:
    integer representing the status (one of HEALTHY, ACTIVE, WARNING or DEAD)
  - calculateMemoryLoad
```
public static int calculateMemoryLoad(Status stat)
```
    Deprecated.
    
    Method will calculate the memory load: used / max = load. The load value is an integer between 1 and 100. It is the percent memory used. Changed this to be more like other system monitors. Peter Lin 2-11-05
    
    Parameters:
    stat - status information about the jvm
    
    Returns:
    memory load
  - calculateThreadLoad
```
public static int calculateThreadLoad(Status stat)
```
    Deprecated.
    
    Method will calculate the thread load: busy / max = load. The value is an integer between 1 and 100. It is the percent busy.
    
    Parameters:
    stat - status information about the server
    
    Returns:
    thread load
