# syslog-py

Syslog client for Python 3 (RFC 3164/5424) for UNIX and Windows (fork from pysyslogclient with more features, fixed bugs and options).

## Installation
```
pip install syslog-py
```

## Description

Syslog client following

* RFC3164 (https://www.ietf.org/rfc/rfc3164.txt)
* RFC5424 (https://www.ietf.org/rfc/rfc5424.txt)
* RFC6587 (https://www.ietf.org/rfc/rfc6587.txt) - for syslog over TCP

with UNIX and Windows support. TCP and UDP transport is possible.

If TCP is used, on every log message that is sent to the specified server,
and a connection error occurs, the message will be dismissed, and
reconnection will be tried for the next message.

## Usage

A small CLI client is implemented in *client.py*. To call it, run

```
python -m pysyslogclient.cli
```

### Startup client 

To set up the client for RFC5424 over TCP to send to SERVER:PORT:

```
import pysyslogclient
client = pysyslogclient.SyslogClientRFC5424(SERVER, PORT, proto="TCP")
```

or for RFC3164:

```
import SyslogClient
client = pysyslogclient.SyslogClientRFC3164(SERVER, PORT, proto="TCP")
```

### Log a message

Log the message "Hello syslog server" with standard severity *INFO* as facility
*USER*. As a program name *SyslogClient* the PID of the called python interpreter
is used.

```
client.log("Hello syslog server")

```

To specify more options, call log with more arguments. For example to log
the message as program *Logger* with PID *1* as facility *SYSTEM* with severity
*EMERGENCY*, call log the following way:

```
client.log("Hello syslog server",
	facility=pysyslogclient.FAC_SYSTEM,
	severity=pysyslogclient.SEV_EMERGENCY,
	program="Logger",
	pid=1)
```

For TCP protocol, the octet parameter is available in client constructor and in log method.
The parameter in log method has precedence over constructor parameter.
In case of UDP protocol, octet parameter is ignored.

Below in the first message, octet stuffing is in use, in second octet counting (forced by octet parameter in log method).
```
import pysyslogclient
client = pysyslogclient.SyslogClientRFC5424(SERVER, 
    PORT, 
    proto="TCP", 
    octet=pysyslogclient.OCTET_STUFFING)

client.log("Hello syslog server",
	facility=pysyslogclient.FAC_SYSTEM,
	severity=pysyslogclient.SEV_EMERGENCY,
	program="Logger",
	pid=1)

client.log("Hello syslog server",
	facility=pysyslogclient.FAC_SYSTEM,
	severity=pysyslogclient.SEV_EMERGENCY,
	program="Logger",
	pid=1,
	octet=pysyslogclient.OCTET_COUNTING)
```

When octet stuffing in use (for a tcp or udp), the trailer type can be selected by constructor parameter.
Applicable to both RFC3164 and RFC5424. Default value is TRAILER_LF

```
import SyslogClient
client = pysyslogclient.SyslogClientRFC3164(SERVER, 
    PORT, 
    proto="TCP", 
    octet=pysyslogclient.OCTET_STUFFING, 
    trailer=pysyslogclient.TRAILER_CRLF)

```

For RFC5424, when datetime is given explicitly (in log method parameterd), the is_utc parameter is utilized to determine if given datetime is utc one. 

### Shutdown

To disconnect, call

```
client.close()
```
