The Alert log, which is a series of text files, supplements the Pega logs (console logs). Typically, an Alert log file is named PegaRULES-Alert-YYYY-MMM-DD.log, where the date portion of the name indicates the date when the application server was started on the node. Security alerts are recorded in a similar file named PegaRULES-AlertSecurity-YYYY-MM-DD.log.
You can view the current Alert log or download the current Alert Log from the server to your workstation.

To view only those alerts from your own requestor session, select Alerts from the Designer Studio toolbar. See Working with the My Alerts display.
The table below describes the Pega 7 alert categories. Threshold settings in the prconfig.xml file or Prconfig Dynamic System Settings affect the operation and criteria of many alerts. For detailed information about every field reported by each alert category, see PDN article Performance alerts, security alerts, and AES.
The Alert log may contain any of the following alerts; the category description appears on the My Alerts display.

The PegaRULES Log Analyzer (PLA) is a Web application that can parse, consolidate and summarize alert logs.
For basic information on PLA, see PDN articles Understanding the PegaRULES Log Analyzer and How to use the PegaRULES Log Analyzer.
You can use the Pega 7 application Autonomic Event Services (AES), Enterprise Edition to parse, consolidate and summarize alert logs.
See PDN articles How to perform log analysis in Autonomic Event Services (AES) Enterprise Edition
Fields in the Alert log are separated by an asterisk character. You can import the Alert log into Microsoft Excel for viewing, searching, sorting, or other analysis:
PEGA-ALERT-ZZZZ.log file and click Open. The Text Import Wizard starts.
Note: Access the PDN to obtain the latest copy of the Alerts.xls Excel template. This can speed and simplify parsing and summarizing Alert logs.
Each line of the log contains multiple fields, delimited by a single asterisk character. Each line contains these fields. The first column identifies the Excel column after import.

| C | Message ID | Identifier of alert type, for example PEGA0011. |
| D | KPI Value | Observed duration in milliseconds or count of value, known as the key performance indicator. |
| E | KPI Threshold | Threshold value for this alert type, in milliseconds or count. |

Message text and description |
| SECU0001 | Security | Security alert. An HTTP request referenced an unexpected property. These can arise from an improperly coded URL JavaServer Page tag. |
| SECU0002 | Security | Security alert. An HTTP POST operation sent an XML document containing clipboard page details from a web node within a Pega Composite Application. |
| SEC0003 | Security | Security alert. A requestor on a web node, within a Pega Composite Application, attempted to execute an activity or list view rule that is not marked for web node execution. The attempt was ignored. |
| SEC0004 | Security | Security alert. A URL received from a web node, within a Pega Composite Application, contained the pyStream parameter. The URL was ignored. |
| SEC0005 | Security | Security alert. A Thread name in the URL of an HTTP request contains invalid characters. See How to detect when a Thread name in a URL contains invalid characters. |
The Alert log identifies the names of activities and other rules executed. By default for alerts of types PEGA0002 to PEGA0007, parameter values and SQL statements containing property values also appear. You can include the suppressInserts and includeParameterPage keyword in the prconfig.xml file so that parameter values and other potentially sensitive data values are omitted in prepared statement inserts:
1. Add the following to the prconfig.xml file:
<env name="alerts/database/operationTimeThreshold/suppressInserts"
value="true" />
<env name="alerts/general/includeParameterPage" value="false" />
2. Stop and restart or redeploy the system.
Note: As an alternative to the prconfig.xml file, you can use Dynamic System Settings to configure your application.
See How to create or update a prconfig setting.
An appender setting in the prlogging.xml file determines the name and existence of the Alert log.
The Alert log supports the optional Autonomic Event Services component, which summarizes and monitors alerts across multiple nodes in a cluster.
