DTrace Gurus,
Is there a way to truncate multiple aggregations collectively?
For Example, to display 20 or less records for the below:
...
@a[pid,self->addr,self->name,self->id] = sum(itema);
@b[pid,self->addr,self->name,self->id] = sum(itemb);
@c[pid,self->addr,self->name,self->id] = sum(itemc);
@d[pid,self->addr,self->name,self->id] = sum(itemd);
@e[pid,self->addr,self->name,self->id] = sum(iteme);
...
trunc(@a, @b, @c, @d, @e, ..., 20);
...
printa("%5s %@3d %@3d %@3d %@3d %@3d %a %s/%d\n",
%a, %b, %c, %d, %e);
...
Cheers,
Joel.
Hi Joel,> Is there a way to truncate multiple aggregations collectively?No. The trunc() function just operates on a single aggregation.

Joel, please file it if you can come up with a sufficiently precise specification. Adam -- Adam Leventhal, Fishworks http://blogs.sun.com/ahl

Trying to pull together a full suggested fix. About 70% there...CR 6886770. Thanks, Joel.
