How to check programmatically whether apache tomcat is running or not in python?

Question

Is there any way available to check the status of a apache tomcat server from another machine in python?

For example, A restful API is running in a machine with apache tomcat server in 8086 port.

Now, what I want is to check the status of the apache tomcat service of the specified machine from my pc programmatically in python.

Yes,I could check the machine is running or not through pinging by using os.system in python.

import os
hostname = "xxx.xxx.xxx.xxx" #example
response = os.system("ping -c 1 " + hostname)

#and then check the response...
if response == 0:
    print hostname, 'is up!'
else:
    print hostname, 'is down!'

But, what I am interested in is that, is it possible to check the status of the service (real_ip:8086/BotAPI) in stead of the liveness of the machine, programmatically in python ?

Update: using paramiko I got the following traceback

channel.exec_command('ps -ef| grep tomcat')
Traceback (most recent call last):
File "<pyshell#67>", line 1, in <module>
channel.exec_command('ps -ef| grep tomcat')
File "E:\python\lib\site-packages\paramiko\channel.py", line 63, in _check

raise e
paramiko.ssh_exception.SSHException: Channel closed.

Can you ssh into the tomcat machine? – lapinkoira Sep 25 '17 at 09:52 — lapinkoira, Sep 25 '17 at 09:52
Yes. I could remotely logged in to the tomcat machine. – S.Rakin Sep 25 '17 at 09:55 — S.Rakin, Sep 25 '17 at 09:55

You could use fabric or paramiko to connect remotely to your tomcat machine and then check if the process is running

import paramiko

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('hostname', username='user', password='password')

transport = ssh.get_transport()
channel = transport.open_session()
channel.exec_command('ps -ef | grep tomcat')

status = channel.recv_exit_status()

Will it work in windows ? My tomcat machine is in windows 10. – S.Rakin Sep 25 '17 at 10:00
w10? do you have that w10 shell? something like this https://stackoverflow.com/questions/40057339/running-tomcat-from-windows-10-bash-shell – lapinkoira Sep 25 '17 at 10:05
No, It's running directly in netbeans. – S.Rakin Sep 25 '17 at 10:07
well, you should check your firewall and user permissions – lapinkoira Sep 25 '17 at 10:24
ssh.coneect works. but now channel.exec_command is not working... @lapinkoira – S.Rakin Sep 25 '17 at 11:12
Is there any windows version of that ? – S.Rakin Sep 25 '17 at 11:15
does it give an traceback? – lapinkoira Sep 25 '17 at 11:15
