Python classes to allow for tailing of multiple files via SSH.
Project description
A simple set of Python classes to facilitate tailing of one or more files via SSH. At the moment it only supports key-based SSH’ing.
Quick installation
Install from PyPI:
> easy_install -U python-sshtail
Tailing a single file
from sshtail import SSHTailer from time import sleep # "1.2.3.4" is the IP address or host name you want to access tailer = SSHTailer('1.2.3.4', '/var/log/path/to/my/logfile.log') try: while 1: for line in tailer.tail(): print line # wait a bit time.sleep(1) except: tailer.disconnect()
Tailing multiple files
from sshtail import SSHMultiTailer tailer = SSHMultiTailer({ '1.2.3.4': ['/path/to/log1.log', '/path/to/log2.log'], '4.3.2.1': ['/path/to/log3.log'], }) # will run until it receives SIGINT, after which it will # automatically catch the exception, disconnect from the # remote hosts and perform cleanup for host, filename, line in tailer.tail(): print "%s:%s - %s" % (host, filename, line)
Using a custom private key
from sshtail import SSHMultiTailer, load_dss_key # if no path's specified for the private key file name, # it automatically prepends /home/<current_user>/.ssh/ # and for RSA keys, import load_rsa_key instead. tailer = SSHMultiTailer({ '1.2.3.4': ['/path/to/log1.log', '/path/to/log2.log'], '4.3.2.1': ['/path/to/log3.log'], }, private_key=load_dss_key('identity')) for host, filename, line in tailer.tail(): print "%s:%s - %s" % (host, filename, line)
