# Configuration file for pmsnap(1)
#
# This file controls the output of pmsnap.
# See the manual page for pmsnap(1) for full details.
#
# Although not mandatory, it is strongly advised that you follow
# the instructions described in the manual page for pmlogger_daily(1)
# before proceeding with the instructions described in pmsnap(1).
#
# Each line below (which is not a comment) has 4 columns, with
# the following meaning ..
#
# (1) Name : name of the output file. This is typically
# in the local Web content directory hierarchy.
#
# (2) Folio : use the named PCP archive, OR use the archives
# in the named PCP archive folio. This is usually
# in PCP_LOG_DIR/pmlogger/HOSTNAME, but may be the path of an
# archive on an NFS/CIFS mounted filesystem if logging is done
# on a remote host. Note that pmlogger_daily(1) automatically
# creates the folio PCP_LOG_DIR/pmlogger/LOCALHOSTNAME/Latest.
#
# (3) Config : the pmchart "view" to use. If not found in the
# local directory (relative to the -o flag), pmsnap
# will also search the directories $PCP_VAR_DIR/config/pmsnap,
# $PCP_VAR_DIR/config/pmchart, and $PCP_VAR_DIR/config/pmchart.
#
# (4) Arguments : passed to pmchart, see pmchart(1). Note that $commonargs
# will be prepended to the argument list (see the assignment to
# $commonargs below). Do NOT include any of the following
# arguments: -o -c -a
#
# Notes : the string LOCALHOSTNAME in this file will be substituted
# by the name of the local host by pmsnap at run-time.
# If pmlogger is logging Snap metrics on the local host,
# the example below should work virtually out of the box,
# provided you want the output images in /var/www/htdocs/snapshots.
# You will of course need to publish an html page that shows
# the generated gif images - you can use the example provided
# in the file $PCP_VAR_DIR/config/pmsnap/Snap.html.
#
# : lines beginning with $ are assumed to be assignments to
# environment variables in the style of sh(1), and all text
# following the $ will be eval'ed by the script reading
# this control file, and the corresponding variable
# exported into the environment.
#
# Recommended pmchart arguments :
# -g 650x600 (raw image size, Width x Height)
# -t 1min (update interval, i.e. time between ticks on the X-Axis)
# -v 30 (number of visible points)
# -O -0 (show end of archive, backwards by (-vh) * (-t) seconds)
# -A 10min (aligned to start at the nearest 10 minutes)
# -W (generated image has a white background, not transparent)
