At the end the installer automatically starts the configuration interface. You will use these to configure the syslog-ng agent for Windows and to restart it. No matter what you use, the following simple configuration works with any recent syslog-ng release.
You can either append it to syslog-ng. This configuration defines two sets of sources and destinations. The first one uses the legacy syslog protocol on port The second one uses the new syslog protocol on port In this case the destination file uses JSON formatting to show the name-value-pairs created by the syslog-ng agent for Windows and forwarded using the new syslog protocol.
You will see some filtering related settings below it. For now, we leave those alone. It opens a new window. Now stop and start syslog-ng agent for Windows using the menu items in the Windows Start menu for the configuration to take effect. With both the syslog-ng server and the agent for Windows configured you are now ready to check your log messages.
While the agent is configured to use the new syslog protocol by default, most people still stick to the legacy protocol. Using correlation, these can be collected into a single new message. It collects log messages from Windows hosts and forwards them — by source-initiated push subscriptions and WinRM protocol - to a syslog-ng Premium Edition server 7.
Whether it's user activity, performance metrics, network traffic or any other log data, syslog-ng can collect and centralize log data. Most log messages traditionally come from three types: system logs of servers, network devices, and applications. Operating systems, applications, and network devices generate text messages of the events that happen to them: a user logs in, a file is created, a network connection is opened to a remote host.

Enterprise class log management software Whether it's user activity, performance metrics, Windows events logs, network traffic or any other log data, syslog-ng can collect and centralize log data.
Key features Secure transfer and storage Have confidence in the data underlying your analytics, forensics and compliance efforts. Secure Transfer using TLS Log messages may contain sensitive information that should not be accessed by third parties. TLS also allows the mutual authentication of the host and the server using X. Secure, Encrypted Log Storage syslog-ng Premium Edition can store log messages securely in encrypted, compressed, indexed and timestamped binary files, so any sensitive data is available only for authorized personnel who have the appropriate encryption key.
Timestamps can be requested from external timestamping authorities. Scalable architecture. Extreme message rate collection The syslog-ng application is optimized for performance, and can handle an enormous amount of messages. Collection from thousands of sources With the syslog-ng client-relay architecture, IT organizations can collect log messages from more than 10, log sources across a geographically distributed environment on one central log server.
Easy monitoring syslog-ng allows you to granularly select which statistics of syslog-ng you want to monitor. Scaling to large networks with syslog-ng This short video will show you how syslog-ng scales to the largest IT environments, ensuring your log infrastructure can reliably and securely collect and manage log data.
Flexible log routing. Disabling filters or sources means that the syslog-ng Agent ignores the disabled settings: that is, if the file sources are disabled, the agent does not send the messages from the files to the server. For details, see the following procedure. When connecting to a syslog-ng server using an encrypted connection, the syslog-ng Agent for Windows verifies the certificate of the server.
The connection can be established only if the syslog-ng Agent for Windows can verify the certificate of the syslog server. For details on importing certificates, see Procedure 6. This certificate sometimes also called the CACert of the server is not the certificate of the server: it is the certificate of the CA that signed the certificate of the server.
Right-click on the server that accepts encrypted connections and select Properties. The connection is established only if the syslog-ng Agent for Windows can verify the certificate of the syslog server. To compress the messages during transfer to save bandwidth, select the Allow Compression option. Note that for syslog-ng Agent to actually use compression, the following points must be met.
The logserver must be configured to enable compression. If the logserver is syslog-ng PE the proper allow-compress option must be enabled in the source. When the syslog-ng server is configured to use mutual authentication, it requests a certificate from the syslog-ng clients. Use the Certificate Import Wizard to import this certificate. For details, see Procedure 6. Procedure 6. Configuring mutual authentication with the syslog-ng Agent for Windows.
If the syslog-ng server requests authentication from the syslog-ng Agent, complete the following steps. Create certificates for the clients. By default, the syslog-ng Agent will look for a certificate that contains the hostname or IP address of the central syslog-ng server in its Common Name. If you use a different Common Name, do not forget to complete Step 3 to set the Common Name of the certificate.
The agent will look for the server name or address set in the Server Name field of the destination. If the certificate of the client has a different Common Name, complete the following steps:. Right-click on the server that requires mutual authentication and select Properties. If you have more than one certificates with the same Common Name, alternatively, you can type the Distinguished Name DN of the certificate into the Client Certificate Subject field.
When using the Distinguished Name, type only the elements of the name, separated with comma, starting with the country. A common way is to use the hostname or the IP address of the host running the syslog-ng Agent as the Common Name of the certificate for example syslog-ng-agent1.
Importing certificates with the Microsoft Management Console. Start Microsoft Management Console by executing mmc. Click Add , select the Certificates module, and click Add. Select Computer account in the displayed window and click Next. The Certificate Import Wizard will be displayed. Click Next. Optional step : Certificates used to authenticate the syslog-ng Agent in mutual authentication include the private key.
Provide the password for the private key when requested. Windows offers a suitable certificate store by default, so click Next. Click Finish on the summary window and Yes on the window that marks the successful importing of the certificate. The syslog-ng Agent for Windows application can filter log messages both in blacklist- and whitelist fashion.
When using blacklisting, you can define filters, and any message that matches the filters is ignored by the agent — only messages that do not match the filters are sent to the central server.
When using whitelisting, you can define filters, and the messages matching the filters are forwarded to the central server — other messages are ignored. By default, blacklist filtering is used. If you define multiple filters, the messages must match every filter.
In other words, the filters are connected to each other with logical AND operations. Different filters are available for eventlog- and file sources. When the syslog-ng Agent processes a message, it checks the relevant filters one-by-one: for example if it finds a blacklist filter that matches the message, the agent stops processing the message without sending it to the server. By default, all filters are case sensitive. For details on how to change this behavior, see Procedure 5.
For details on how to filter messages received from eventlog sources, see Procedure 7. For details on how to filter messages received from file sources, see Procedure 7. For details on how to disable filtering globally, see Procedure 5.
The following types of filters are available for eventlog sources. Unless described otherwise, the filters match only if the same string appears in the related field of the message. When filtering on the message source, the values of the Source field can be incorrect in some cases. Sources : Filter on the source application that created the message.
Sources and Event ID : Filter on the source application that created the message, and optionally on the identification number of the event. In this filter you can use regular expressions. Sources and Categories : Filter on the source application that created the message, and optionally on the category of the event. Users : Filter on the username associated with the event. Computers : Filter on the name of the computer host that created the event.
Corresponds with the HOST macro. Event Types : Filter on the type of the event. Select the General tab, and right-click on the value of the Source field. Select Copy. Save the saved value somewhere, you will need it later to configure the filter in syslog-ng Agent. It is important to use this method, because the actual value of the Source field can be longer than what the Event Viewer displays. For example, for security messages, the displayed source is often Microsoft Windows security , while the full name of the source is Microsoft Windows security auditing.
Hovering your mouse over the value of the Source field also displays the full name of the source. Right-click Event Filters. If you want to use both global and local server side filtering, first global filters will be applied to the eventlog messages and then the local filters.
To use whitelist-filtering, select White List Filtering. By default, syslog-ng Agent uses blacklist filtering. To ignore messages sent by a specific application, or messages of the application with a specific event ID, double-click on Sources and Event ID , select Add , and enter the name of the source application whose messages you want to ignore into the Source Name field.
To ignore only specific messages of the application, enter the ID of the event into the Event ID field. To ignore messages sent by a specific application, or messages of the application that fall into a specific category, double-click on Sources and Categories , select Add , and select the name of the application whose messages you want to ignore from the Application Name field.
To ignore only those messages of the application that fall into a specific category, enter the name of the category into the Category field. Under Windows Vista and Server , Windows labels certain messages as level 3 and the Event Viewer labels such messages as warnings. This is against the official specification: level 3 should not be used, and only level 2 messages are warnings.
File Name : Filter on the file name. Only available for destination file filters. Syslog is an event logging protocol that is common to Linux. Applications will send messages that may be stored on the local machine or delivered to a Syslog collector. When the Log Analytics agent for Linux is installed, it configures the local Syslog daemon to forward messages to the agent.
The agent then sends the message to Azure Monitor where a corresponding record is created. This article covers collecting Syslog events with the Log Analytics agent which is one of the agents used by Azure Monitor.
Other agents collect different data and are configured differently. See Overview of Azure Monitor agents for a list of the available agents and the data they can collect. Azure Monitor supports collection of messages sent by rsyslog or syslog-ng, where rsyslog is the default daemon.
To collect syslog data from this version of these distributions, the rsyslog daemon should be installed and configured to replace sysklog. For any other facility, configure a Custom Logs data source in Azure Monitor. The Log Analytics agent for Linux will only collect events with the facilities and severities that are specified in its configuration. You can configure Syslog through the Azure portal or by managing configuration files on your Linux agents. Configure Syslog from the Agent configuration menu for the Log Analytics workspace.
This configuration is delivered to the configuration file on each Linux agent.
