+name: implementing-syslog-centralization-with-rsyslog
+description: >-
+  Configure rsyslog for centralized log collection with TLS encryption, custom templates,
+  and log rotation. Generates server and client configuration files with GnuTLS stream
+  drivers, x509 certificate authentication, per-host log segregation, and reliable
+  queue settings for high-availability syslog infrastructure.
+---
+
+## Instructions
+
+1. Install dependencies: `pip install jinja2 paramiko`
+2. Generate TLS certificates for rsyslog server and clients using OpenSSL.
+3. Run the agent to generate rsyslog server and client configurations:
+   - Server: TLS listener on port 6514, per-host directory output, JSON-format templates
+   - Client: TLS forwarding with disk-assisted queues for reliability
+4. Deploy configurations to servers via SSH (paramiko).
+5. Validate TLS connectivity and log delivery.
+
+```bash
+python scripts/agent.py --server-ip 10.0.0.1 --clients 10.0.0.10,10.0.0.11 --ca-cert ca.pem --output syslog_report.json
+```
+
+## Examples
+
+### Server Configuration (TLS)
+```
+module(load="imtcp" StreamDriver.Name="gtls" StreamDriver.Mode="1"
+       StreamDriver.Authmode="x509/name")
+input(type="imtcp" port="6514")
+template(name="PerHostLog" type="string" string="/var/log/remote/%HOSTNAME%/%PROGRAMNAME%.log")
+*.* ?PerHostLog
+```
+
+### Client Configuration (Reliable Forwarding)
+```
+action(type="omfwd" target="10.0.0.1" port="6514" protocol="tcp"
+       StreamDriver="gtls" StreamDriverMode="1"
+       StreamDriverAuthMode="x509/name"
+       queue.type="LinkedList" queue.filename="fwdRule1"
+       queue.maxdiskspace="1g" queue.saveonshutdown="on"
+       action.resumeRetryCount="-1")
+```
