root/i-scream/experimental/reports/queuegraphing/watch.pl
Revision: 1.3
Committed: Sun Oct 21 19:01:16 2001 UTC (22 years, 6 months ago) by tdb
Content type: text/plain
Branch: MAIN
Changes since 1.2: +4 -2 lines
Log Message:
It's only worth cleaning the png files if there are no other rrds left.
In the case that there are some left, the graphs may be incorrect for a
short while until graph.pl is run, but this seems better than having no
graphs at all... which would break the php page.
