Configuration

JobScheduler - SystemMonitorNotification files

Location: <scheduler_install>/config/notification

FileDescription
SystemMonitorNotification_v1.0.xsd

The XML Schema file that defines which values are allowed in your XML files for the JobScheduler monitoring.

That means, you just have to modify your SystemMonitorNotification_<MonitorSystem>.xml files in order to configure the JobScheduler objects you want to monitor and the System Monitor you want to use but the XML schema does not have to be modified.

SystemMonitorNotification_<MonitorSystem>.xml

 Configuration file for each System Monitor.

  • Specifies the delivery way to System Monitor.
  • Specifies notification for error or success conditions
  • Specifies notification to measure performance of JobScheduler objects
 

SystemMonitorNotificationTimers.xml

Configuration file for all System Monitors.

  • Specifies notification to measure performance of JobScheduler objects

This file is optional and contains the definitions of the SystemMonitorNotification / Timer elements.

JobScheduler - Job Chains

See https://kb.sos-berlin.com/display/PKB/JobScheduler+Monitoring+Interface+-+Prerequisites+and+Installation#JobSchedulerMonitoringInterface-PrerequisitesandInstallation-JobChainConfiguration

 

WORK IN PROGRESS

Use Cases

Recoverable Errors

Initial Situation: A Job Chain is triggered by directory monitoring. That is, when a certain file comes in a monitored folder, the Job Chain starts.

Problem: The Job Chain ended with error.

Handling: The System Monitor will be notified to the service related to the Job Chain with the message error. If a new execution of the Job Chain from a new file end without errors, does not mean that the error is recovered, since the file that has been processed is now another one. That is, the error message at the System Monitor will stay till the same file is again placed in the monitored directory and the Job Chain ends without errors.

Configuration:

  • XML CheckConfigurationHistory.xml: Indicate the ID of the JobScheduler and the name of the Job Chain you want to monitor.
  • XML SystemMonitorNotification.xml: Specify the name of the Service (in the System Monitor) and specify that it is about a service_name_on_error since you want to have the control when the Job Chain ends in an error.
  • System Monitor: Services in the System Monitor have to be configured and named the same way as in the XML file above SystemMonitorNotification.xml.

Workflow Execution takes too long

Initial Situation: A Job Chain is triggered and it could not end, it hanged in a step, taking then longer than expected.

Problem: Execution time was too long

Handling: A timer for this Job Chain is set and the System Monitor will be notified about it. The expiration times for the Job Chains are configured with enough time for processing, that means, this is usually used for cases where the Job Chain hanged in a specific step.

Configuration:

  • XML CheckConfigurationHistory.xml: As in the example above, indicate the ID of the JobScheduler and the name of the Job Chain you want to monitor. Moreover, specify the timer for this specific job chain and the function to calculate the expiration time for the timer.
  • XML SystemMonitorNotification.xml: As in the example above, specify the name of the Service (in the System Monitor) and specify that it is about a service_name_on_error since you want to have the control when the Job Chain ends in an error. Moreover and essential for this particular case, specify how many times the timer should notify your System Monitor about the expiration of a timer.
  • System Monitor: As in the example above, Services in the System Monitor have to be configured and named the same way as in the XML file above SystemMonitorNotification.xml.

SFTP connection refused

Initial Situation: There is a Job Chain that uses SFTP for transferring files. You have a setback configured in this step of the Job Chain, so that if the connection to the SFTP server fails, this step is retried after some time.

Problem: The SFTP server is not available anymore.

Handling: The System Monitor will be notified to the service related to the Job Chain with the message error. However, you don't want to have a bunch of notifications for a Job Chain when is an external factor, the connection to the SFTP Server, what is producing the error.

Configuration:

  • XML CheckConfigurationHistory.xml: As in the example above, indicate the ID of the JobScheduler and the name of the Job Chain you want to monitor.
  • XML SystemMonitorNotification.xml: As in the example above, specify the name of the Service (in the System Monitor) and specify that it is about a service_name_on_error since you want to have the control when the Job Chain ends in an error. Moreover and very important in this case, specify how many times this Job Chain should notify your System Monitor about the error connecting to the SFTP Server. You can use step_from andstep_to for that in order to reduce the number of notifications for this specific step.
  • System Monitor: As in the example above, Services in the System Monitor have to be configured and named the same way as in the XML file above SystemMonitorNotification.xml.

Thresholds

Initial Situation: For example, a specific number of Workflow Executions have to be executed successfully till some specific time. That is, a specific value has to be monitored in order to determine if this quote was reached.

Handling: A new service for History is configured, so that the workflow executions (Job Chains in the JobScheduler vocabulary) send the information that they were executed and finished to the System Monitor.

Configuration:

  • XML CheckConfigurationHistory.xml: As in the example above, indicate the ID of the JobScheduler and the name of the Job Chain you want to monitor.
  • XML SystemMonitorNotification.xml: Specify the name of the Service (in the System Monitor) but now specify that it is about a service_name_on_success since you want to have the control when the Job Chain ends in an success, and not only when it ends on error.
  • System Monitor: As in the example above, Services in the System Monitor have to be configured and named the same way as in the XML file above SystemMonitorNotification.xml.

Acknowledgement

Initial Situation: An alert for a Service has been sent to the System Monitor and a Mail has been sent to the Service Desk (Support Team) notifying about it.

Handling: The problem is well known by the Service Desk and the "acknowledge" the problem. Through the acknowledgement JobScheduler will be notified to and will not send any more notification for this Service to the System Monitor till the Service is again recovered.

Configuration:

  • System Monitor: The step of notifying JobScheduler through an acknowledgement in the System Monitor is an execution of a script. This is nothing else than a notification, like sending a mail for instance, but instead, another action is executed, which is the execution of the script that contacts JobScheduler and add an order to the JobChain ResetNotifications described above.
