This line shows up a lot in my http error log:
PHP Notice: Undefined index: gs in
/var/www/html/ganglia/get_context.php on line 44
I googled it, came up pretty dry. Is there a way to shut it up, should
I not even worry about it, or what?
It looks like the code is checking to see whether a gs variable is set
in the URL, and then defaults to whatever. Why then is a message
ending up in my log? Could logging be set too verbose?
Many thanks,
Dave
grep -C5 gs /var/www/html/ganglia/get_context.php

# The direction we are travelling in the grid tree
$gridwalk = isset($_GET["gw"]) ?
escapeshellcmd($_GET["gw"]) : NULL;
# A stack of grid parents. Prefer a GET variable, default to cookie.
if (isset($_GET["gs"]) and $_GET["gs"])
$gridstack = explode(">", rawurldecode($_GET["gs"]));
else
$gridstack = explode(">", $_COOKIE["gs"] );
# Assume we are the first grid visited in the tree if there are no CGI
variables,
# or gridstack is not well formed. Gridstack always has at least one element.
if (!count($_GET) or !strstr($gridstack[0], "http://";))
$initgrid=TRUE;
