Attribute and parameter properties
The following table describes the metadata that is available for each attribute monitored by PATROL for PostgreSQL.
| Property | Default value |
|---|---|
Application class | The application class under which this parameter is displayed. |
Command type | Language used to create the command this parameter executes. Example: PATROL Script Language (PSL) |
Icon style | Specifies whether the parameter is represented as a graph, text box, stop light (signal), or boolean state. |
Unit | Specifies the unit of measure in which the parameter output is expressed, such as a percentage, a number, or bytes. |
Border range | Indicates the normal operating range for the parameter. The Border range must be larger than the Alarm1 and Alarm2 ranges combined. Values are described as less than and greater than, for example <0 or >100. If the Border range is undefined, it means it is inactive and any values that appear are not intended as recommendations. |
Alarm1 range | Specifies the thresholds for the first-level alarm; this is not applicable to collector parameters. Specifies the thresholds for the lower numerical values deemed unacceptable for this parameter. Values must be lower than values for Alarm2; cannot overlap Alarm2 range or fall outside the Border range. Values falling inside this range trigger warnings, alarms, or recovery actions. If undefined, Alarm1 is inactive, and any values that appear are not intended as recommendations. |
Alarm2 range | Specifies the thresholds for the second-level alarm; this is not applicable to collector parameters. Specifies the thresholds for the higher numerical values deemed unacceptable for this parameter. Values must be higher than the values for Alarm1; cannot overlap Alarm1 range, or fall outside the Border range. Values falling inside this range trigger warnings, alarms, or recovery actions. If undefined, Alarm2 is inactive, and any values that appear are not intended as recommendations. |
Scheduling (poll time) | Specifies how frequently the parameter will run and collect data (polling cycle); this is not applicable to consumer parameters. |
Active at installation | Specifies whether a parameter is active by default; reflected in the words yes or no. |
Parameter type | Indicates the parameter type:
A PATROL collector parameter executes commands and gathers data for a consumer parameter to display, often collecting many values. It does not display any values itself. As such, it does not have alarms or runs any recovery actions. Collector parameters are defined in the collector's application class rather than in the applications for which they collect data. This avoids the situation in which a separate collector would execute for each application instance and negate the efficiency of the collector or consumer parameter.
A consumer parameter only displays a value that is collected by a collector parameter. A consumer parameter never issues commands; it is not scheduled for execution, but it has alarms and can run recovery actions. A consumer parameter cannot be updated directly by selecting an option on its display. To update a consumer parameter, you must execute the collector that gathers its data. For additional information about parameters and defining your own parameters, see the PATROL Console Help or the PATROL user guide for your console. |
Value set by | Lists the collector parameter that sets the values for the consumer parameter described. |
| Monitor Type | The monitor type under which this attribute is displayed. |
Key Performance Indicator | Indicates if the attribute is a Key Performance Indicator (KPI). KPIs are attributes that have the most impact on the health and performance of your environment and your service-level agreements. |
Monitor for abnormalities | Indicates whether abnormalities should be detected automatically. This applies to all attributes for which alarm ranges have been defined. If you want an attribute to be monitored for abnormalities, you should define the alarm ranges. |
Graph | Indicates whether the attribute value should be plotted on the graph by default when the Show Graph is selected on the ProactiveNet user interface. |
Availability | Indicates whether the parameter monitors the availability of the resource. |
Response time | Indicates whether the parameter monitors the response time of an action or operation. |
Normal distribution | Indicates whether the attribute has data with extreme spikes which makes developing a normal range band difficult. |
Statistical | Indicates if the value collected by the attribute is numerical and indicates performance data. |
