I could see some agents reporting status 'E' and 'R' many a times. What does E and R exactly mean?
A - Status ended Job ended with a return code that is not equal 0.
E - Status ended Job ended on status ENDED_OK.
R - Status running This status is written to the log file periodically while the job is being executed.
V - Status vanished This status only occurs when the agent cannot find a job anymore that it has started
W - Status waiting Job has not yet started and is in a waiting condition.
