Free SAN and storage performance and capacity monitoring
STOR2RRD generates historical utilization graphs of monitored storages and the SAN.
It retrieves performance data via the storage API and via SNMP protocol from the SAN switches.
It collects and presents complete logical configuration of all storages.
It graphically presents IO rate, data throughput and response times for all Ports, Pools, Ranks, Mdisks, Volumes (LUNs) and drives.
