Thread-topic: pmwebd: Defining the directory for PCP Archives
Hello Frank,

I have been very careful and clicked only once.
Each time I click, I see the icon on the Graphite composer window blink,
and the following entries in the log
[Sat Dec  6 20:34:58] pmwebd(2993): [10.17.1.18:36430] HTTP/1.1 GET 
/graphite/render/ _salt=1417898098.642 height=421

timespan [1417811698-1417898098 by 85], in 3.459ms

The icon on the Graphite compose points to :
http://pmlog.inf.mel.mmd:44323/graphite/render/?width=533&height=421&_salt=1417898098.642&target=-2F-var-2F-logdata-2F-pmlogger-2F-archdb1-2E-prd-2E-mel-2F-20141121-2E-meta.mysql.status.aborted_clients&target=-2F-var-2F-logdata-2F-pmlogger-2F-archdb1-2E-prd-2E-mel-2F-20141121-2E-meta.disk.all.avactive

And the metric on the left hand window points to:
http://pmlog.inf.mel.mmd:44323/graphite/composer/index.html?=

Please help. We have put some new servers in production, and have a real
need to display data from these.

Thanks and regards
Chandana
