API /stats ctl-iscsi disk_ops-X-Y

[Lucien9]

Hello,

I am buidling some scripts to pull performance data from FreeNAS using /api/v2.0/stats

Listing available stats sources (/stat/get_sources) shows the following for "ctl-iscsi":

Code:

"ctl-iscsi": [
    "disk_octets-1-1",
    "disk_ops",
    "disk_time",
    "disk_time-1-1",
    "disk_octets",
    "disk_ops-1-1",
    "disk_time-2-3",
    "disk_ops-1-2",
    "disk_ops-2-3",
    "disk_time-1-2",
    "disk_octets-1-4",
    "disk_ops-1-4",
    "disk_octets-2-3",
    "disk_octets-1-2",
    "disk_time-1-4"
],

I figured out the numbers X-Y refer to a combination iSCSI portal and target.

But is seems quite dynamic...

1) started with single target on portal 1 -> 1-1
2) created a new target with portal 1 and got combination 1-2
3) changed the portal of the new target to 2 and got combination 2-3
4) changed the portal of the new target back to 1 and got 1-4
5) removed the new target completely

As you can see all the combinations still exist even though I now have only one target.

My questions are:
1) Is there any way to tell which X-Y combination refers to which target?
2) Is there a way to clean up old X-Y combinations from the stats?

Thanks and regards,

Lucien

Did you find a solution for this?

No solution so far.
I have noticed that unused combinations disapear after some time (makes sense).
But I stil have no clue how to match X-Y combination with an iSCSI target.
