Alarm Configuration
The fields in the Alarms Watch display include:
Index | The index is a number that uniquely identifies each alarm. |
| Index numbers are |
| scheme that works for you. These numbers are permanently |
| assigned to their associated alarms; however, index numbers |
| made available by the deletion of existing alarms can be |
| assigned to new alarms, as needed. Note that indices 2000 to |
| 3999 are reserved and unavailable. |
Interval | Indicates the amount of time, in seconds, over which the |
| selected variable will be sampled. At the end of the interval, |
| the sample value is compared to both the rising and falling |
| thresholds configured for the alarm. |
Sample | Indicates whether the sample value to be compared to the |
| thresholds is an absolute, or total value — that is, the total |
| value counted for the selected variable during the interval — or |
| a relative, or delta value — the difference between the value |
| counted during the current interval and the value counted |
| during the previous interval. |
LoThrshld | Indicates the set value for the low, or falling threshold. |
Event # | Indicates the event index number that the falling threshold |
| points to: this is the event that will be triggered if the falling |
| threshold is met or crossed. If the value for this field is zero, no |
| event will be triggered. |
HiThrshld | Indicates the set value for the high, or rising threshold. |
Event # | Indicates the event index number that the rising threshold |
| points to: the event that will be triggered if the rising threshold |
| is met or crossed. If the value for this field is zero, no event |
| will be triggered. |
Status | Indicates the status of the alarm: valid, invalid, or |
| underCreation. An alarm that is invalid is not functional; it |
| may be referring to a MIB component that is inactive (such as |
| the Hosts component), not present, or unreachable, or it may |
| have been deleted by software but not yet removed from |
| memory at the device. An alarm that is underCreation is in the |
| process of being configured (possibly by another management |
| station), and should not be modified until its status is valid; if it |
| never reaches valid status, it will eventually be removed. |
Alarm Variable | Indicates the variable that is being watched. You can use the |
| scroll bar, if necessary, to view the complete name. |
Note that the information provided in this screen is static once it is displayed; for updated information, click on the Refresh button. Adding or modifying an alarm automatically updates the list.
