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")
|
|
```
