Looking up <Private DNS> failed

[adjourn]

I use latest Amazon Linux AMI, collectd version is 5.7.1-3.19.amzn1.

I started with #5 steps but setup fails. After digging into this, I realized that configuration has changed a lot, here's what I did:

(echo "1"; echo "1"; echo "1"; echo "1"; ecyho "1"; echo "1"; echo "1"; echo "2"; echo "1"; echo "3"; cat) | python setup.py

[1] get region automatically
[1] get EC2 instance id automatically
[1] choose IAM role
[1] no proxy server name
[1] no proxy server port
[1] no ASG metrics
[1] no fixed metric dimension
[2] no high resolution metrics
[1] default flush interval (60s)
[3] use CloudWatch recommended configuration (4 metrics)

But I still get the following response:

...
Enter choice [3]: Plugin configuration written successfully.
Stopping collectd process ... NOT OK
Starting collectd process ... NOT OK
Installation cancelled due to an error.
Executed command: '/usr/sbin/collectd'.
Error output: ''.

plugin.conf still messed up, blocked_metrics, whitelist.conf are empty and /var/log/messages:

ip-10-10-5-245 seems to be first part of private DNS ip-10-10-5-245.<region>.compute.internal.

Any ideas? I have no idea how to resolve this.

Could you check if "collectd-python" package installed on your system? for exampe: rpm -qa| grep collectd-python. If no , please install it with "yum install -y collectd-python"

And we support non-interactive mode now, you can run ./setup.py -h for help

[yimuniao]

For example:

[root@ip-172-31-34-234 ~]# ./setup.py -h usage: setup.py [-h] [-I] [-H HOST_NAME] [-r REGION] [-n NAME] [-p PORT] [-e] [-f FLUSH_INTERVAL] [-a ACCESS_KEY] [-s SECRET_KEY] [-P CREDENTIALS_PATH] [-m recommended|add|not_modify] [-g] [-c] [-v DIMENSION_VALUE] [-d] [-D]

You can run "./setup.py -I -a *accesskey* -s securitykey***" to install this plugin.

I still get the same error with sudo python ./setup.py -I.

Terminal after running setup:

Plugin configuration written successfully.

sudo yum list installed | grep collectd:

sudo service collectd restart:

not restarting due to configuration error

[yimuniao]

I guess you are missing "yum install -y collectd-python" And you can try "sudo python ./setup.py -I -m recommended"

[adjourn]

I think I stopped trying to make it work after some frustration. Closing this.
