Note: this component is designated "advanced", which means that objects of this type are not expected to be created or altered in most environments. If you believe that such a change is necessary, you may want to contact support in order to understand the potential impact of that change.
This plugin logs server statistics to the specified log file at the specified interval. Statistics can be logged either in JSON format or in a comma-separated format. This is primarily used for profiling server performance. Unless the log-interval property is set too small, this has a negligible impact on performance.

| Admin Action Required | None. Modification requires no further action |
| Description | Indicates whether the plug-in is enabled for use. |
| Default Value | None |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | Yes |
| Admin Action Required | None. Modification requires no further action |
| Description | Specifies the level of detail to include for Data Governance Server metrics including metrics for the Policy Evaluation. |
| Default Value | none |
| Allowed Values | none - No details are included about Data Governance Server metrics. basic - All details are included about Data Governance Server metrics. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | The duration between statistics collection and logging. A new line is logged to the output for each interval. Setting this value too small can have an impact on performance. |
| Default Value | 5 seconds |
| Allowed Values | A duration. Lower limit is 10 milliseconds. |
| Multi-Valued | No |
| Required | Yes |
| Admin Action Required | None. Modification requires no further action |
| Description | If the server is idle during the specified interval, then do not log any output if this property is set to true. The server is idle if during the interval, no new connections were established, no operations were processed, and no operations are pending. |
| Default Value | false |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | Yes |
| Admin Action Required | None. Modification requires no further action |
| Description | This property controls whether the header prefix, which applies to a group of columns, appears at the start of each column header or only the first column in a group. Columns associated with the same monitor entry are grouped together in the output. If this property is set to true, then each column header will include the full prefix. This makes it easier to automatically parse the output. If set to false, then only the first column for each group of columns will include the header prefix. This makes the column header more compact. |
| Default Value | false |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | This property controls whether a value in the output is shown as empty if the value is zero. If the value of a column is zero, then it can alternatively be shown as empty. This can make it easier to visually spot non-zero values, but it can also increase the complexity of automatically parsing the output. Even if this is set to true, some columns might show up as zero. |
| Default Value | true |
| Allowed Values | true false |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | The number of lines to log between logging the header line that summarizes the columns in the table. |
| Default Value | 50 |
| Allowed Values | An integer value. Lower limit is 0. |
| Multi-Valued | No |
| Required | Yes |
| Admin Action Required | None. Modification requires no further action |
| Description | Specifies whether statistics related to resource utilization such as JVM memory. |
| Default Value | None |
| Allowed Values | memory-utilization - Statistics related to memory consumers, garbage collection, and the amount of JVM memory used. |
| Multi-Valued | Yes |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | Specifies the level of detail to include about the status summary monitor entry. |
| Default Value | none |
| Allowed Values | none - No details are included from the status summary monitor entry. basic - Only basic information is included from the status summary monitor entry. verbose - Verbose information is included from the status summary monitor entry. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |
| Description | Specifies the format to use when logging server statistics. |
| Default Value | csv |
| Allowed Values | csv - Statistics are logged in comma-separated format. json - Statistics are logged in JSON format. |
| Multi-Valued | No |
| Required | No |
| Admin Action Required | None. Modification requires no further action |

| Default Value | None |
| Allowed Values | A filesystem path |
| Multi-Valued | No |
| Required | Yes |
| Admin Action Required | The Periodic Stats Logger Plugin must be disabled and re-enabled for changes to this setting to take effect. In order for this modification to take effect, the component must be restarted, either by disabling and re-enabling it, or by restarting the server |

| Allowed Values | cpu - Information is included about the CPU and memory utilization. This data is produced by Host System Cpu Memory Monitor Provider. disk - Information is included about the disk utilization of selected disks. Disks to be reported are configured in Host System Disk Monitor Provider. network - Information is included about network utilization of selected interfaces. Networks to be reported are configured in Host System Network Monitor Provider. |
