run a health check script on cloud server through paramiko

[amritjsr]

The desire output means, it's not able execute the given command properly. There are few things to mention ...
1. It's able to log into the server
2. It's able to invoke_shell ( i can see from other ssh console on same server)
3. if i leave the root part as of now it's may/may-not able to execute the given command but i am unable to capture the output.
What possibly, i am thinking i am not able to figure out the command prompt ( may be script is running fast and tty is slow ) and send the command and gather the output ...

Yes, above mentioned output is the whole one, not truncated at all.

---

Here i want to mention one thing ... if i keep adding sleep for couple of seconds in between then we are getting desire out but along with error too .... as below ...
