Monitor windows event log

This script will remember your last Index position in the log, and only report events which occurred since then. It also remembers the TimeGenerated of the oldest log entry, so that it can detect when the log has been cleared.

Example: eventlog. Use -Force or -Restart to create a new position file. Rebuilding position file because -Force was specified. Terminating operation. Use -Force or -Restart to rebuild the position file. Count — 1]. Count — This script or discussion may require slight adjustments before it applies directly to newer builds.

Why monitor event logs? Requirements for monitoring event logs Activity Requirements Monitor local event logs The Splunk universal forwarder or Splunk Enterprise instance must run on Windows.

See Install on Windows in the Installation Manual. The Splunk universal forwarder or Splunk Enterprise instance must run as the Local System Windows user to read all local event logs. Monitor remote event logs The universal forwarder or heavy forwarder must run on the Windows machine from which you want to collect event logs. The Splunk universal forwarder or heavy forwarder must run as a domain or remote user with read access to Windows Management Instrumentation WMI on the remote machine.

The user that the forwarder runs as must have read access to the event logs you want to collect. Security and other considerations for collecting event log data from remote machines You collect event log data from remote machines using a universal forwarder, a heavy forwarder, or WMI. If you do not specify a domain controller, then the input does the following: The input attempts to use the local system cache to authenticate or resolve SIDs. If the monitor cannot authenticate or resolve SIDs that way, it attempts a connection to the domain controller that the machine that runs the input used to log in.

If that does not work, then the input attempts to use the closest AD domain controller that has a copy of the Global Catalog. If the domain controller that you specify is not valid, or a domain controller cannot be found, then the input generates an error message.

Collect event logs from a remote Windows machine You have two choices to collect data from a remote Windows machine: Use a universal forwarder Use WMI Use a universal or heavy forwarder You can install a universal forwarder or a heavy forwarder on the Windows machine and instruct it to collect event logs.

On the Windows machine for which you want to collect Windows Event Logs, download Splunk Enterprise or the universal forwarder software. Run the universal forwarder installation package to begin the installation process.

When the installer prompts you, configure a receiving indexer. When the installer prompts you to specify inputs, enable the event log inputs by checking the Event logs checkbox. Complete the installation procedure. To change event log security to get access to the event logs from remote machines, you must meet the following requirements: Have administrator access to the machine from which you are collecting event logs.

Decide how to monitor your data. See Considerations for deciding how to monitor remote Windows data for information on collecting data from remote Windows machines. You can use the wevtutil utility to set event log security. Download a Splunk Enterprise instance onto a Windows machine. Double-click the installer file to begin the installation. When the installer prompts you to specify a user, select Domain user. Select Matching Regular Expression Below to specify regular expressions that match text that appears in the events.

This string field is case sensitive. To learn about regular expressions syntax, see. Select the "With Keywords Below" option to specify keywords or phrases as the match criteria. Select "Matching Regular Expression Below" to specify regular expressions that match text that appears in the events. Enter the number of polling intervals worth of time you want to search the event logs.

Fractional values are supported. Message and other details of matched events will be available for viewing and alerting when enabled. Select whether a found match should set the component status to Up or Down. Select the "Yes, convert returned value" option to display fields where you can select a common function or enter a custom formula.
