Server Level Monitoring
S.M.A.R.T
The CDS incorporates S.M.A.R.T. to monitor the reliability of a hard drive, predict drive failures, and
to carry out different types of drive self-tests. S.M.A.R.T is firmware, native to most disk drives, that
monitors disk attributes over time, making it possible to perform predictive failure analysis. Advanced
warning of predictive failures allows the operator to perform preventative maintenance.
To view the current read/write activity that has occurred in the last five seconds on the selected disk,
click Graph Disks. Figure 5-16 shows an example of the Disk Activity graph.
Figure 5-16 Disk Monitor—Streamer Disk Activity Graph
The Disk Activity graph displays an average calculation of the amount of data read (in megabytes per
second) and data writes over a five-second period.
NIC Monitor
The NIC Monitor page displays the status of each network interface card (NIC) on the server.
To view the current status of a NIC on a server, choose the IP address of the server from the drop-down
list on the NIC Monitor page, click Display, and click one of the NIC ports displayed in the graphic.
Figure 5-17 shows an example of the eth4 interface on a Streamer server.
To change how often the information is refreshed, enter the number of seconds in the Data Refresh Rate
field. The default is 10 seconds. The range is 10 to 300. All field values that are updated, based on the
refresh rate, are initially shown in a green font.
Number of Reads Number of bytes read from the disk since it was powered on.
Number of Writes Number of bytes written to the disk since it was powered on.
