The Windows Legacy app provides insight into your Windows system's operation and events so that you can better manage and maintain your environment. The Windows Legacy app consists of predefined searches and dashboards that provide visibility into your environment for real-time analysis of overall usage of Security Status, System Activity, Updates, and User Activity.

## Log types

The Windows Legacy app assumes events are coming from Remote Windows Event Log Sources. It does not work with third party logs. Standard Windows event channels include:
* Security
* Application
* System

Custom event channels, such as PowerShell or Internet Explorer are also supported.


### Sample log messages


```bash
instance of Win32_NTLogEvent
{
    Category = 13571;
    CategoryString = "MPSSVC Rule-Level Policy Change";
    ComputerName = "aphrodite.sumolab.org";
    EventCode = 4957;
    EventIdentifier = 4957;
    EventType = 5;
    InsertionStrings = {"CoreNet-IPHTTPS-In", "Core Networking - IPHTTPS (TCP-In)", "Local Port"};
    Logfile = "Security";
    Message = "Windows Firewall did not apply the following rule:

    Rule Information:
    ID: CoreNet-IPHTTPS-In
    Name: Core Networking - IPHTTPS (TCP-In)

    Error Information:
    Reason: Local Port resolved to an empty set.";
    RecordNumber = 1441653878;
    SourceName = "Microsoft-Windows-Security-Auditing";
    TimeGenerated = "20130411232352.140400-000";
    TimeWritten = "20130411232352.140400-000";
    Type = "Audit Failure";
};
```

### Sample queries

```sumo title="Recent Policy Changes"
_sourceCategory=OS/Windows "Policy Change"
| parse regex "CategoryString = \"(?<category>[^\"]+?)\";[\s\S]+?Logfile = \"Security\""
| count by category
| where category matches "*Policy Change*"
```


## Collecting logs for Windows Legacy

This section provides instructions on configuring log collection for the Windows Legacy app, so that logs are collected from the Microsoft Windows Event Log and ingested into Sumo Logic. A sample log message and example query are also provided.

[Windows Performance](/docs/integrations/microsoft-azure/performance) is considered a separate data type.


### Configure a Collector and a Source

To configure a collector and source, do the following:

1. Configure an [Installed Windows collector](/docs/send-data/installed-collectors/windows) through the user interface or from the command line.
2. Configure either a local or remote Windows Event Log source. To configure a Windows Event Log source, set **Event Format** to **Collect using legacy format**.<br/><img src={useBaseUrl('img/integrations/microsoft-azure/Event_Format_Legacy.png')} alt="Event_Format_Legacy" />

Events retain their default text format from Windows.

For more information on local or remote Windows Event Log Source configuration, refer to [Local Windows Event Log Source](/docs/send-data/installed-collectors/sources/local-windows-event-log-source) and [Remote Windows Event Log Source](/docs/send-data/installed-collectors/sources/remote-windows-event-log-source).

### Event Errors

See information about Window event messages that contain a keyword that indicates a problem. (If a Windows event contains  "error", "timeout", "exception", or "fail", Sumo tags the message with "error_keyword", "timeout_keyword", "exception_keyword", or "fail_keyword" respectively.)

<img src={useBaseUrl('https://sumologic-app-data.s3.amazonaws.com/dashboards/Windows/EventErrors.png')} alt="Event Errors" />

**Breakdown by Keyword Tag**. A donut chart that shows the breakdown of problem keywords encountered in event messages over the last 24 hours.

**Error Keyword - One Day Time Comparison**. A table that shows the count of each keyword tag ("error_keyword", "timeout_keyword", "exception_keyword", or "fail_keyword") over the last 24 hours, compared to the same information for the previous day.

**Error Keyword Trend**. A line chart that shows the count of each keyword tag per 15 minute timeslice over the last 24 hours.

**Error Keyword - Outlier**. See timeslices where the count of problem keywords exceeds the moving average by a statistically significant amount, three standard deviations over the last 24 hours.

**Error Keyword - LogReduce**. See a LogReduce analysis of event messages that contain problem keywords. (Sumo's LogReduce algorithm uses fuzzy logic to cluster messages together based on string and pattern similarity. For more information, see, [Detect Patterns with LogReduce](/docs/search/behavior-insights/logreduce/detect-patterns-with-logreduce)).
