Stats
public class Stats (Code)
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.



Field Summary
final public static  intACTIVE
    
final public static  doubleACTIVE_PER
    
final public static  intDEAD
    
final public static  intDEFAULT_MEMORY_FACTOR
    
final public static  intDEFAULT_THREAD_FACTOR
    
final public static  intHEALTHY
    
final public static  doubleHEALTHY_PER
    
final public static  intWARNING
    
final public static  doubleWARNING_PER
    


Method Summary
public static  intcalculateLoad(Status stat)
     The method is responsible for taking a status object and calculating an int value from 1 to 100.
public static  intcalculateMemoryLoad(Status stat)
     Method will calculate the memory load: used / max = load.
public static  intcalculateStatus(Status stat)
     Method should calculate if the server is: dead, active, warning or healthy.
public static  intcalculateThreadLoad(Status stat)
     Method will calculate the thread load: busy / max = load.

Field Detail
ACTIVE
final public static int ACTIVE(Code)



ACTIVE_PER
final public static double ACTIVE_PER(Code)



DEAD
final public static int DEAD(Code)



DEFAULT_MEMORY_FACTOR
final public static int DEFAULT_MEMORY_FACTOR(Code)



DEFAULT_THREAD_FACTOR
final public static int DEFAULT_THREAD_FACTOR(Code)



HEALTHY
final public static int HEALTHY(Code)



HEALTHY_PER
final public static double HEALTHY_PER(Code)



WARNING
final public static int WARNING(Code)



WARNING_PER
final public static double WARNING_PER(Code)





Method Detail
calculateLoad
public static int calculateLoad(Status stat)(Code)
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 - calculated load value




calculateMemoryLoad
public static int calculateMemoryLoad(Status stat)(Code)
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 - memory load



calculateStatus
public static int calculateStatus(Status stat)(Code)
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 - integer representing the status



calculateThreadLoad
public static int calculateThreadLoad(Status stat)(Code)
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 - thread load
