Recently we have been facing problem on RDS as our allocated diskspace is getting exhausted on Amazon RDS.
So is there any tool/plugins (nagios plugin) available or any other utility through which we can monitor RDS Disk utilization?
P.S: We know cloudwatch can do this, but we are looking for other alternatives as well.
We use this check_cloudwatch plugin to grab any cloudwatch metric so it can graphed in our private cloud using PNP4Nagios and Graphite, works very well.
