eG Monitoring
 

Measures reported by LHRaidCtrCacheTest

Each SAN storage array is composed of disk/RAID controllers with caches. Cache memory in the disk/storage RAID controller enhances read and write performance, improving overall storage throughput. Streaming data can be queued into the cache to dramatically accelerate read performance. This test monitors each disk controller cache in the storage system and reports its size and status.

Outputs of the test : One set of results for each cache of the storage controller on the target storage system being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Cache_status Indicates the current status of this cache.   The values reported by this measure and their corresponding numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Normal 1
Abnormal 2
Note:

This measure reports the Measure Values listed in the table above to indicate the current state of each cache. However, in the graph of this measure, the state is indicated using only the Numeric Values listed in the above table.
Cache_size Indicates the size of this cache. KB
