syslog-ng Open Source Edition 3.18 - Administration Guide

Start the SQL Server Management Studio application. Select Start > Programs > Microsoft SQL Server 2005 > SQL Server Management Studio.

Create a new database.

1. Figure 5: Creating a new MSSQL database 1.

   

   In the Object Explorer, right-click on the Databases entry and select New Database.

2. Figure 6: Creating a new MSSQL database 2.

   

   Enter the name of the new database (for example syslogng) into the Database name field and click OK.

Create a new database user and associate it with the new database.

1. Figure 7: Creating a new MSSQL user 1.

   

   In the Object Explorer, select Security, right-click on the Logins entry, then select New Login.

2. Figure 8: Creating a new MSSQL user 2.

   

   Enter a name (for example syslog-ng) for the user into the Login name field.

3. Select the SQL Server Authentication option and enter a password for the user.

4. In the Default database field, select the database created in Step 2 (for example syslogng).

5. In the Default language field, select the language of log messages that you want to store in the database, then click OK.

   Caution: Incorrect language settings may result in the database converting the messages to a different character-encoding format. That way the log messages may become unreadable, causing information loss.

6. In the Object Explorer, select Security > Logins, then right-click on the new login created in the previous step, and select Properties.

7. Figure 9: Associating database with the new user

   

   Select User Mapping. In the Users mapped to this login option, check the line corresponding to the new login (for example syslogng). In the Database role membership field, check the db_owner and public options.

Figure 10: Associating database with the new user

Enable remote logins for SQL users.

In the Object Explorer right-click on your database server, and select Properties > Security, and set the Server Authentication option to SQL Server and Windows Authentication mode.

Install the syslog-ng application on the host. For details installing syslog-ng on specific operating systems, see Installing syslog-ng.

Configure the local sources to collect the log messages of the host. Starting with version 3.2, syslog-ng OSE automatically collects the log messages that use the native system logging method of the platform, for example, messages from /dev/log on Linux, or /dev/klog on FreeBSD. For a complete list of messages that are collected automatically, see system: Collecting the system-specific log messages of a platform.

To configure syslog-ng OSE, edit the syslog-ng.conf file with any regular text editor application. The location of the configuration file depends on how you installed syslog-ng OSE. Native packages of a platform (like the ones downloaded from Linux repositories) typically place the configuration file under the /etc/syslog-ng/ directory.

Add sources to collect the messages from your log files. File sources look like this:

source s_myfilesource {
    file("/var/log/myapplication.log" follow-freq(1));
};

Name every source uniquely. For details on configuring file sources, see file: Collecting messages from text files.

source s_local {
    system();
    internal();
};

Create a network destination that points directly to the syslog-ng server, or to a local relay. The network destination greatly depends on the protocol that your log server or relay accepts messages. Many systems still use the legacy BSD-syslog protocol (RFC3162) over the unreliable UDP transport:

destination d_network { network("10.1.2.3" transport("udp")); };

However, if possible, use the much more reliable IETF-syslog protocol over TCP transport:

destination d_network {
    syslog("10.1.2.3" transport("tcp"));
};

Create a log statement connecting the local sources to the syslog-ng server or relay. For example:

log {
    source(s_local); destination(d_network);
};

If the logs will also be stored locally on the host, create local file destinations.

destination d_local {
    file("/var/log/messages");
};

Create a log statement connecting the local sources to the file destination.

log {
    source(s_local); destination(d_local);
};

Set filters, macros and other features and options (for example TLS encryption) as necessary.
