I forked Scalr on github and put in my changes there. You can get it from
https://github.com/ssrini/scalr
1. RRDGraph error - Files changed:
./src/LibWebta/library/Data/RRD/class.RRDGraph.php
./cron/watchers/class.LASNMPWatcher.php
./cron/watchers/class.MEMSNMPWatcher.php
./cron/watchers/class.NETSNMPWatcher.php
./cron/watchers/class.CPUSNMPWatcher.php
2. Since my pecl rrd was also the latest, I also had php errors with
rrd_create() and rrd_update(). These changes are made in the
file ./src/LibWebta/library/Data/RRD/class.RRD.php. Make these changes
only based on your PECL RRD version.
