Configure CA LDAP syslog forwarding using rsyslog

This section describes how to configure rsyslog on the CA Directory server to forward logs to the Bindplane agent.

Identify CA Directory log file locations

CA Directory stores log files in the following locations:

• Linux: /opt/CA/Directory/dxserver/logs/
• Windows: C:\Program Files\CA\Directory\dxserver\logs\

The log files follow naming patterns based on the DSA name (for example, democorp_alarm, democorp_warn, democorp_trace).

Available log types

CA Directory generates the following log types:

• Alarm log: Critical events (always enabled)
• Warn log: Errors and warnings
• Trace log: Detailed operation tracing
• Query log: Detailed operation information with timestamps
• Summary log: Operation summaries
• Connection log: Connection and disconnection events
• Diagnostic log: Rejected operations
• Statistics log: Per-minute operational statistics
• Update log: Add, modify, rename, and delete operations
• Time log: Operation timing information

Configure rsyslog on Linux

1. Sign in to the CA Directory server as root or with sudo privileges.

2. Install rsyslog if not already installed:

   sudo yum install rsyslog
   

   Or for Debian/Ubuntu:

   sudo apt-get install rsyslog
   

3. Create a new rsyslog configuration file for CA Directory:

   sudo nano /etc/rsyslog.d/ca-directory.conf
   

4. Add the following configuration to forward CA Directory logs:

   # Load the imfile module for file monitoring
   module(load="imfile" PollingInterval="10")
   
   # Monitor CA Directory alarm logs
   input(type="imfile"
       File="/opt/CA/Directory/dxserver/logs/*_alarm*"
       Tag="ca-directory-alarm"
       Severity="error"
       Facility="local0")
   
   # Monitor CA Directory warn logs
   input(type="imfile"
       File="/opt/CA/Directory/dxserver/logs/*_warn*"
       Tag="ca-directory-warn"
       Severity="warning"
       Facility="local0")
   
   # Monitor CA Directory trace logs
   input(type="imfile"
       File="/opt/CA/Directory/dxserver/logs/*_trace*"
       Tag="ca-directory-trace"
       Severity="info"
       Facility="local0")
   
   # Monitor CA Directory query logs
   input(type="imfile"
       File="/opt/CA/Directory/dxserver/logs/*_query*"
       Tag="ca-directory-query"
       Severity="info"
       Facility="local0")
   
   # Monitor CA Directory connection logs
   input(type="imfile"
       File="/opt/CA/Directory/dxserver/logs/*_connection*"
       Tag="ca-directory-connection"
       Severity="info"
       Facility="local0")
   
   # Monitor CA Directory update logs
   input(type="imfile"
       File="/opt/CA/Directory/dxserver/logs/*_update*"
       Tag="ca-directory-update"
       Severity="info"
       Facility="local0")
   
   # Forward all CA Directory logs to Bindplane agent
   if $syslogtag contains 'ca-directory' then @@BINDPLANE_AGENT_IP:514
   & stop
   

5. Replace BINDPLANE_AGENT_IP with the IP address of the Bindplane agent host:

   • If Bindplane agent is on the same server: 127.0.0.1
   • If Bindplane agent is on a different server: Enter the IP address (for example, 192.168.1.100)
   Note: The @@ prefix indicates TCP forwarding. Use @ for UDP forwarding (for example, @BINDPLANE_AGENT_IP:514).

6. Save the configuration file:

   Press Ctrl+O, then Enter, then Ctrl+X

7. Verify the rsyslog configuration syntax:

   sudo rsyslogd -N1
   

8. Restart the rsyslog service:

   sudo systemctl restart rsyslog
   

9. Verify rsyslog is running:

   sudo systemctl status rsyslog
   

10. Check rsyslog logs for errors:

    sudo tail -f /var/log/messages
    

Configure rsyslog on Windows

1. Download and install rsyslog for Windows from the rsyslog website.

2. Open the rsyslog configuration file:

   notepad "C:\Program Files\rsyslog\rsyslog.conf"
   

3. Add the following configuration:

   # Load the imfile module for file monitoring
   module(load="imfile" PollingInterval="10")
   
   # Monitor CA Directory alarm logs
   input(type="imfile"
       File="C:\\Program Files\\CA\\Directory\\dxserver\\logs\\*_alarm*"
       Tag="ca-directory-alarm"
       Severity="error"
       Facility="local0")
   
   # Monitor CA Directory warn logs
   input(type="imfile"
       File="C:\\Program Files\\CA\\Directory\\dxserver\\logs\\*_warn*"
       Tag="ca-directory-warn"
       Severity="warning"
       Facility="local0")
   
   # Monitor CA Directory trace logs
   input(type="imfile"
       File="C:\\Program Files\\CA\\Directory\\dxserver\\logs\\*_trace*"
       Tag="ca-directory-trace"
       Severity="info"
       Facility="local0")
   
   # Forward all CA Directory logs to Bindplane agent
   if $syslogtag contains 'ca-directory' then @@BINDPLANE_AGENT_IP:514
   & stop
   

4. Replace BINDPLANE_AGENT_IP with the IP address of the Bindplane agent host.

5. Save the configuration file.

6. Restart the rsyslog service:

   net stop rsyslog
   net start rsyslog
   

Enable CA Directory logging

Ensure that the required log types are enabled in CA Directory:

1. Edit the DSA configuration file:

   • Linux: /opt/CA/Directory/dxserver/config/servers/democorp.dxc
   • Windows: C:\Program Files\CA\Directory\dxserver\config\servers\democorp.dxc
   Note: Replace democorp with your DSA name.

2. Verify or add the following logging settings:

       set alarm-log = true;
       set warn-log = true;
       set trace-log = true;
       set query-log = true;
       set connection-log = true;
       set update-log = true;
   

3. Save the configuration file.

4. Restart the CA Directory DSA:

   • Linux:

     dxserver stop democorp
     dxserver start democorp
     

   • Windows:

     net stop "CA Directory DSA - democorp"
     net start "CA Directory DSA - democorp"
     

Verify log forwarding

1. Generate test activity in CA Directory by performing LDAP queries or authentication attempts.

2. Check the Bindplane agent logs to verify logs are being received:

   • Linux:

     sudo journalctl -u observiq-otel-collector -f
     

   • Windows:

     type "C:\Program Files\observIQ OpenTelemetry Collector\log\collector.log"
     

3. Sign in to the Google SecOps console and verify that CA Directory logs are appearing in the log viewer.
