There is some information about the progress of utilities, including probkup, in the _userstatus VST. You'll need the user number of the backup client.
From Dan Foreman's VST Guide:
This VST does not seem to be ‘aware’ of:
* Running proutil dbanalys online
* Running proutil idxfix online
* Running probkup online
A while back I created a slightly modified version of the userstatus program from Dan's book. I forget what changes I made but I think it was just adding new statuses from the docs. I just tested it during an online backup, idxfix, and dbanalys:
Operation Usr# Name Obj# Object Phase Phase description Counter Target ────────────── ──── ────────── ───── ─ ─────────────────────────────────── ───── ──────────────────────────────────────── ─────────── ─────────── Online Backup 6 root 0 I 66 BK_backup_DB_blks_per_area 0 0 Chain Analysis 7 root 0 I 73 AN_examine_DB_blocks 0 0 Idxfix scan id 8 root -1590 I _StorageObject._Object-PartitionId 52 Scan_indexes 1727 0
It looks like "counter" and "target" don't always provide useful information. But the _userstatus-state field does appear to be populated with valid values.
This is in 11.6.3.017 on CentOS.
