Job Monitoring
This page explains how we can monitor a Job.
The user can use the Job Monitoring feature to track a Job and its associated tasks. On this page, the user can view details such as Job Status, Last Activated (Date and Time), Last Deactivated (Date and Time), Total Allocated and Consumed CPU, and Total Allocated and Consumed Memory, all presented together on Job monitoring page.
Please go through the below given walk-through on the Job monitoring function.

Total Allocated CPU: Total allocated CPU in cores.
Total Allocated Memory: Total allocated memory in MB.
Total Consumed CPU: Total consumed CPU by the Job in cores.
Total Consumed Memory: Total consumed memory by the Job in MB.
Instance Name: Instance name of the Job (e.g., Driver and Executors for Spark and PySpark Jobs).
Last Processed Time: Last processed time of the instance.
Min CPU Usage: Minimum CPU usage in cores by the instance.
Max CPU Usage: Maximum CPU usage in cores by the instance.
Min Memory Usage: Minimum memory usage in MB by the instance.
Max Memory Usage: Maximum memory usage in MB by the instance.
CPU Utilization: Total CPU utilization in cores by the instance.
Memory Utilization: Total memory utilization in MB by the instance.
There are two tabs present on the Job Monitoring page:
Monitor: This tab will show all the resource allocated and consumption details for each task or instance in the job.
System Logs: This tab will show the Pods logs of the Job.
Please Note: The system logs on the monitoring page will be displayed only when the Job is active.
Once the user clicks on any instance, the page will expand to show the graphical representation of CPU and Memory usage over the given interval of time. For reference, please see the images below.
