Piat Project

Piat is a syslog and trap listeners APIs which are easy to use, it support syslog parsing for multiple vendors

Installing

pip install piat

Getting Started

Example 1:

to run both listeners/servers use the PiatServer API:

from piat.servers import PiatServer

def syslog_cb(syslog_msg):
    """ callback to be executed on received syslog msg """
    data = syslog_msg.get_dictionary()
    # do something with syslog data
    print(data)

def trap_cb(trap_msg):
    """ callback to be executed on received trap msg """
    data = trap_msg.get_dictionary()
    # do something with trap data
    print(data)

if __name__ == '__main__':
    server = PiatServer(traps_callbacks=[trap_cb],
                        syslog_callbacks=[syslog_cb],
                        trap_community='my_community')
    server.start()

syslog data example :

{'ip': '192.168.1.1',
 'timestamp': 
 '2019-04-28 21:26:40.809271',
 'tag': 'LSD-4-LABEL_RESOURCE',
 'severity': 'warning',
 'facility': 'syslogd',
  'msg': 'label range 100-150 exhausted'}

{'ip': '192.168.1.9',
 'timestamp': '2019-04-28 21:26:41.741839',
 'tag': 'SYS-6-LOGGINGHOST_STARTSTOP',
 'severity': 'informational',
 'facility': 'syslogd',
 'msg': 'Logging to host 192.1.1.8 port 514 started - CLI initiated'}

trap data example :

{'ip': '192.168.1.1',
 'timestamp': '2019-04-28 21:30:11.536344',
 'sysUpTime': '88847929',
 'snmpTrapOID': 'CISCO-SMI::cisco.0.1',
 'snmpTrapAddress': '192.168.1.1',
 'snmpTrapCommunity': 'public',
 'snmpTrapEnterprise': 'CISCO-SMI::cisco',
 'local': 'root',
 'tcpConnState': 'finWait2'}

{'ip': '192.168.1.9',
 'timestamp': '2019-04-28 21:30:11.544577',
 'sysUpTime': '88847996',
 'snmpTrapOID': 'CISCO-SYSLOG-MIB::clogMessageGenerated',
 'snmpTrapAddress': '192.168.1.9',
 'snmpTrapCommunity': 'public',
 'snmpTrapEnterprise': 'CISCO-SYSLOG-MIB::ciscoSyslogMIBNotificationPrefix',
 'clogHistFacility': 'LSD',
 'clogHistSeverity': 'warning',
 'clogHistMsgName': 'LABEL_RESOURCE',
 'clogHistMsgText': 'label range 100-150 exhausted',
 'clogHistTimestamp': '88847996'}

Example 2:

to run only syslog server:

from piat.servers import SyslogServer

def syslog_cb(syslog_msg):
    data = syslog_msg.get_dictionary()
    print(data)
    # do something with syslog data

if __name__ == '__main__':
    server = SyslogServer(callbacks=[syslog_cb])
    server.start()

also you can run only trap server:

from piat.servers import SnmpTrapServer

def trap_cb(trap_msg):
    data = trap_msg.get_dictionary()
    # do something with trap data
    print(data)

if __name__ == '__main__':
    server = SnmpTrapServer(callbacks=[trap_cb],community='my_comm')
    server.start()

Supported Vendors:

1. Cisco.
2. Arista.:
3. Juniper.
4. Huawei.
5. HP.
6. F5.
7. Fortinet.

Features:

1. you can pass as many callback as you want, all callbacks will be running concurrently in separate threads.
2. both syslog and trap will be running as an independent process.
3. you can add more mib dir to be used by the trap server, use add_mib_dir kwarg to pass the mib dir location.
4. Piat uses pysnmp for trap listening, so if you want to extend the mib support you need to combile the mib files using mibdump.py command provided by pysnmp to combile the new mibs, then add the compiled mibs dir to piat server using add_mib_dir.
5. we only support Syslog parsing described by rfc3164.
