Define Log Entry Columns
The Columns Tab, found within both Log Consolidation and Log Monitor template properties views, enables you to extract values from log entries then, in the case of log consolidation, save those values to custom columns in your log repository database. Log Monitors use the column definitions to extract key value pairs before applying filters.
Depending on the type of log you are monitoring, different options for extracting key value pairs are utilized.
| Log Type | Description | Help Link |
|---|---|---|
| Event Logs | Uses Regular Expressions to extract values. | Define Log Entry Columns with Regular Expressions |
| Syslogs | Uses Regular Expressions to extract values. | Define Log Entry Columns with Regular Expressions |
| Text Logs | Uses Regular Expressions to extract values. | Define Log Entry Columns with Regular Expressions |
| CSV Files | Scans rows using column definitions. | Define Log Entry Columns with Separated Values |
| W3C Logs | Scans rows using column definitions. | Define Log Entry Columns with Separated Values |
To define column definitions:
-
From the Column Definitions List, click the Add
button.
A new line is added to the list.
-
Each column definition includes the following configurable parameters:
Parameter Description Enabled Enables or disables the column from the result set. Key Defines the value's key for log monitor filters and defines the column name for log consolidation database tables. Name Defines the display value for the column. Data Type Defines the value's data type for log monitor filters and defines the column data type for log consolidation database tables. Column Size When applied to a log consolidation template, defines the maximum size for a string column. Index When applied to a log consolidation template, creates a database index for the column. -
Use the Up Button
and Down Button 
to reorder the column definitions.
Multiple regular expressions enable you to test for different key value pairs. If the same key exists for multiple regular expression results, the last matching regular expression in the list is applied to the result set.
The following data types are supported:
| Data Type | Description |
|---|---|
| bool | A Boolean value, which can be either true or false. |
| byte | Unsigned 8-bit integer |
| short | Signed 16-bit integer |
| int | Signed 32-bit integer |
| long | Signed 64-bit integer |
| ushort | Unsigned 16-bit integer |
| uint | Unsigned 32-bit integer |
| ulong | Unsigned 64-bit integer |
| DateTime | A DateTime value that is parsed from a string using the current locale. |
| TimeSpan | A TimeSpan value that is parsed from a string using the current locale. |
| float | A 4-byte floating point value. |
| double | An 8-byte floating point value. |
| decimal | A 16-byte floating point value. |
| Level | An internal data type for mapping verbose log message level integer values to Levels (e.g. Info, Notice, Critical and Error). |
| File System Size | Unsigned 64-bit integer that is formatted to a file system size string value (e.g. 1 GB). |
| Percent | Signed 32-bit integer that is formatted to a percent string value. |
| Gauge | Signed 32-bit integer that is formatted to a percent then displays as a percentage graphic. |
