Hi Preston!
From some testing I did, it looks like “3 week” will be converted to a time 3 weeks in the future of the current time while “3 week ago” will be converted to a time 3 weeks in the past of the current time.
I still think “ago” should be documented in the nsr_getdate(3) man page. A couple of examples in the mminfo(1m) man page isn’t documentation. Even the mminfo man page says time attributes are specified in nsr_getdate(3)

Regards,

Hi Brett,

It’s certainly referenced in the mminfo documentation; if you check that, you’ll notice it used multiple times in the examples given.

As to the discrepancy you encountered – I’d been using “ago” for so long now that I’ve not run the alternative for years.

Doing a few basic tests, it appears to me that “savetime

[root@nox ~]# mminfo -q “pool=Staging,savetime<3 week" -otR | head -5
 volume        client       date      size   level  name
Staging-01.RO  nox              11/25/2009 38 MB 9  index:archon
Staging-01     nox              11/25/2009 38 MB 9  index:archon
Staging-03.RO  archon    11/25/2009   4  B    incr  /Volumes/TARDIS/Yojimbo
Staging-03     archon    11/25/2009   4  B    incr  /Volumes/TARDIS/Yojimbo

That’s clearly (as of the time I write this reply) from today. However, if I run it with the “3 weeks ago”, I get what I should get:

[root@nox ~]# mminfo -q “pool=Staging,savetime<3 weeks ago" -otR | head -5
 volume        client       date      size   level  name
Staging-01.RO  loki      11/04/2009 497 KB    incr  /
Staging-01     loki      11/04/2009 497 KB    incr  /
Staging-01.RO  loki      11/04/2009   4  B    incr  /boot
Staging-01     loki      11/04/2009   4  B    incr  /boot

So it looks to me that we have an instance of mminfo interpreting “3 week ago” differently to what we’d expect (I.e., it’s coming back as “now”, somehow), but “3 weeks ago” is the correct invocation.

Cheers,

Preston.

Great blog. Lots of good technical networker info. Thanks!
Where is “ago” as in “2 weeks ago” documented? I certainly didn’t see it in nsr_getdate(3).
I believe nsr_getdate mentions relative time is [number] unit.

There also seems to be a difference in the below queries
mminfo -q “pool=pool1, savetime<4 week"
mminfo -q "pool=pool1, savetime<4 week ago"
