Feature request: enhancement on pscheduler monitor command

[msjang]

When there are many tasks in Canceled status, it becomes difficult to monitor Running tasks through the pscheduler monitor command.

1. We need a feature to abbreviate Canceled tasks.
   • It would be helpful to summarize them like ... Canceled 15 tasks ...
2. A filtering feature would be beneficial.
   • It should be compatible with the filter commands from pscheduler schedule
   • Example: pscheduler monitor --filter-test throughput
3. We need options to hide columns or display only selected columns.
   • Due to screen width limitations, we sometimes want to hide less important columns like --source-node or --dest-node
4. We need options for DNS/Reverse DNS resolving.
   • Sometimes we want to see host information as IP addresses, other times as domain names
     Similar to tcpdump -N option

We need a feature to abbreviate Canceled tasks.

How about a switch to exclude runs by state (e.g., --exclude-state canceled)?

A filtering feature would be beneficial.

That's come on in previous tickets #352 and #355. Good, general-purpose filtering is difficult, which is why those tickets are as old as they are.

We need options to hide columns or display only selected columns. ... Due to screen width limitations, we sometimes want to hide less important columns like --source-node or --dest-node

monitor is not like top, which gets a bunch of discrete values that are turned into columns that can be turned on and off. The task description you see is formatted by test plugins inside the server and sent back to the client for display.

The best I could do for that would be an option to remove parts of the string based a regular expression:

--trim-task '--reverse`
--trim-task '--source-node\s\+\S\+\s'

We need options for DNS/Reverse DNS resolving. ... Similar to tcpdump -N option

That I can't do. tcpdump can bypass reverse-resolving IPs because it has IPs to start with. The test parameters are given to pScheduler as strings and are resolved by the tool making the measurement when it's made.
