Monitoring Lefthand SAN Storage Node

eG Enterprise provides you with extensive monitoring capabilities for the Lefthand SAN Storage Node. A single eG agent is capable of monitoring the Lefthand SAN Storage Node. Every layer of the monitoring model is mapped to a wide variety of tests that a single agent executes and extracts loads of performance metrics from the Lefthand SAN Storage Node.

The metrics thus collected would be useful to figure out accurate answers to the following performance queries:

• What is the current status of cluster manager, storage node, Raid controller etc?
• Is the temperature of all the hardware components in admissible range?
• Are the fans in the storage system operating at normal speeds? Is any fan in an abnormal state?
• Are all power supply units in the storage device functioning smoothly, or has any unit in an abnormal state?
• What is the current temperature and fan speed of the CPU?
• Is any storage cluster running out of space?
• How well the space on the storage node was utilized?
• Is there any node that is experiencing significant latencies during processing I/O operations?
• What is the total capacity of each volume?
• What is the level of I/O traffic on each volume?
• Is the volume experiencing any read/write latencies?
• How well data was read from and written to each volume per second?
• Is the cache of any controller in abnormal state?
• What is the health of each raid controller?
• What is the operational status of the raid drive?
• What is the space utilization of snapshots on the storage cluster?
