Shell script to monitor the application health deployed on weblogic

Question

Hi All,
Is it possible to monitor the health of a application deployed on weblogic and send a mail if it is not running. I have JasperServer reporting application deployed on weblogic. The shell script should check if the application is running, if it down a mail should be sent.
Thanks

You can use WLST to get information on the state of your deployments, for example,
the python script can be used
class DeploymentInfo:
     def __init__(self,name,target):
          self.name = name;
          self.target = target;
     def getName(self):
          return self.name;
     def getTarget(self):
          return self.target;
print 'CONNECT TO ADMIN SERVER';
connect('weblogic', 'transfer11g');
print 'OBTAINING DEPLOYMENT INFORMATION';
deploymentsInfo = [];
applications = cmo.getAppDeployments();
for application in applications:
     name = application.getName();
     target = application.getTargets()[0].getName();
     deploymentsInfo.append(DeploymentInfo(name, target));
print 'CHANGE TO DOMAIN RUNTIME ENVIRONMENT';
domainRuntime();
print 'APPLICATION LIFE CYCLE INFORMATION';
applicationRuntime = cmo.getAppRuntimeStateRuntime();
for deploymentInfo in deploymentsInfo:
     state = applicationRuntime.getCurrentState(deploymentInfo.getName(), deploymentInfo.getTarget())
     print 'Application: ' + deploymentInfo.getName() + ', State: ' + state;
     if (state != 'STATE_ACTIVE'):
          startApplication(deploymentInfo.getName());In the example above the application gets started when it is not running, you can also
send an e-mail by using the smtplib package, for example
import smtplib;
server = smtplib.SMTP('email-server-host');
server.set_debuglevel(1);
server.sendmail(fromaddress, toaddress, message);
server.quit();More information on the package smtplib can be found here:
