Measures reported by EnvironmentTest
This test monitors the NetApp storage system's support environment - which includes its hardware, the fans, the power supply units, the battery, and the buffer cache - and promptly alerts you to current/potential issues in the health of this environment. These issues can range from abnormal hardware temperature to batteries fast-approaching their end-of-life to power rail failures and more!
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Temperature |
Indicates whether/not the hardware temperature is normal. |
|
This measure reports a value Normal if the hardware is operating at a normal temperature and a value High if the hardware is operating at a temperature higher than the normal.
The values reported by this measure and their numeric equivalents are available in the table below:
| Measure Value |
Numeric Value |
| Normal |
1 |
| High |
2 |
Note:
This measure reports the Measure Values listed in the table above to indicate whether the temperature of the hardware is normal. However, in the graph of this measure, the state is indicated using only the Numeric Values listed in the above table. |
| Fan_count |
Indicates the number of main unit backplane fans that failed durring the last measurement period. |
Number |
The detailed diagnosis capability, if enabled for this test, will list the fans that failed and the reason for their failure. |
| Power_supply_count |
Indicates the number of power supplies and the power rails that failed during the last measurement period. |
Number |
The detailed diagnosis capability, if enabled for this test, will list the power rails that have failed and the reason for their failure. |
| Battery_Status |
Indicates the current status of the NVRAM battery. |
|
The values reported by this measure and their numeric equivalents are available in the table below:
| Measure Value |
Numeric Value |
| Ok |
1 |
| Partially discharged |
2 |
| Fully discharged |
3 |
| Not present |
4 |
| Near EndOfLife |
5 |
| At EndOfLife |
6 |
| Unknown |
7 |
| Over charged |
8 |
| Fully charged |
9 |
Note:
This measure reports the Measure Values listed in the table above to indicate the current status of the NVRAM battery. However, the graph of this measure will be represented using only the Numeric Values listed in the above table. |
| Cache_age |
Indicates the age of the oldest read only block in the buffer cache. |
Hours |
The value of this measure indicates how fast the read operations are cycling through the system memory. When the appliance is reading very large files (i.e., the files that are larger than the machine's memory size), buffer cache age will be very low. |
