Hi Ellie,
Thanks for raising the problem on github. I now manually renamed the
hostname to 'em' (for ellis VM) and re-installed ellis (by re-running a
bash script I wrote to automate the installing steps, including the
bootstrapping, writing the clearwater config file, fetching the debian
package, generating 1000 number, etc.) And this time, I can see output
from 'sudo monit status'. But another problem rises:
Process 'nginx' Running
Process 'mysql' Running
*Program 'poll_ellis' Status failed**
**Process 'ellis' Does not exist*
Process 'clearwater_diags_monitor' Running
System 'em' Running
I then checked the ellis-0.log. The following Error repeatedly appears:
2015-02-25 21:26:22,779 UTC ERROR utils:434 *Can't dump core - is
clearwater-diags-monitor installed?*
*Traceback* (most recent call last):

with open(filename, "a") as stack_file:

I then checked the folder to which the Error message pointed at:

Hi Lilin,
Is the hostname of your Ellis node 'Ellis'? The monit configuration that
monitors the whole system (called 'ellis') is conflicting with the monit
configuration that monitors the Ellis process (also called 'ellis'). We're
looking into fixing this up (you can track this at
https://github.com/Metaswitch/clearwater-infrastructure/issues/139).
In the meantime, can you change your system hostname to something like ellis-1
(you'll need to edit /etc/hostname and the public_hostname setting in
/etc/clearwater/config). Can you then reboot (to ensure the hostname change is
picked up), and then try the install again?
Thanks,
Ellie

Subject: [Clearwater] Monit unrecognizable in Ellis, Sprout, Homer, Ralf
Hello all,
*I used stable repo*, "deb http://repo.cw-ngv.com/stable binary/", *to manually install*
Ellis, Sprout, Homer, and Ralf nodes; but encounter the error when doing "sudo monit
status":
"*'check system' not defined in control file, failed to add automatic configuration
(service name ellis is used already) -- please add 'check system <name>' manually*"
At Ellis node:
After checking the log of monit confirming that monit isn't running (logs are
pasted at the end), I then checked the status of the following related services:
*nginx is RUNNING**
**clearwater-monit starts/running**
**clearwater-diags.monitor is running*
*ellis is NOT running**
**mysql->ellis->numbers table has 1000 numbers created browser display one line of message
"Welcome to nginx!" when directed to ellis_IP * *browser display one line of message "This
web page is not available"
when directed to ellis_IP:2812
*Please advise where went down here. Thanks!
Lilin
