I installed OpsCenter 1.4.1 on my Mac, but opscenter fails to start. Here's the sequence:
-----------------------
:java -version
java version "1.6.0_29"
:python -V
Python 2.7
:openssl version
OpenSSL 0.9.8r 8 Feb 2011
:cd bin
~/opscenter-1.4.1/bin
:setup.py
Generating a 1024 bit RSA private key

:./opscenter
Traceback (most recent call last):
File "./bin/twistd", line 18, in <module>
from twisted.scripts.twistd import run
ImportError: No module named twisted.scripts.twistd
-----------------------
As I understand it, OSX comes with twisted installed, but I don't see this file anywhere. Did I miss something?

Thanks

Hi,

Can you provide the output of the following commands:
python -c "import twisted; print twisted"
python2.7 -c "import twisted; print twisted"

Can you also add the following line to line 81 of the opscenter script (right above the last line):
echo $PYTHONPATH

and provide that output as well.

Thanks

Also, can you send the output of the following:

python -c "import sys; v = sys.version; print v[:v.index('.', 2)], '###'"

Here are the results:

:python -c "import twisted; print twisted"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named twisted
:python2.7 -c "import twisted; print twisted"
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named twisted

Adding the echo $PYTHONPATH line:

:./opscenter
./src/lib/python2.7 (r27:82508, Jul 3 2010, 21:12:11) [GCC 4/site-packages:./lib/py:./lib/py-osx/2.7 (r27:82508, Jul 3 2010, 21:12:11) [GCC 4/amd64:/Library/Frameworks/Python.framework/Versions/2.7
Traceback (most recent call last):
File "./bin/twistd", line 18, in <module>
from twisted.scripts.twistd import run
ImportError: No module named twisted.scripts.twistd

And finally:

:python -c "import sys; v = sys.version; print v[:v.index('.', 2)], '###'"
2.7 (r27:82508, Jul 3 2010, 21:12:11)
[GCC 4 ###

Thanks

Thanks for that info. We have a fix for this coming in our next version of opscenter. In the meantime, if you'd like to apply the following patch to the opscenter script found in ./bin, you may be able to get it working:

-PY_VER=$($PYTHON -c "import sys; v = sys.version; print v[:v.index('.', 2)]")
+PY_VER=$($PYTHON -c "import platform; v = platform.python_version(); print v[:v.index('.', 2)]")

If you do apply the patch, please let us know if it does or does not work.

Thanks again

That got opscenter working - thanks. I'm on to a new problem: the agent is now displaying this error:

ERROR [pool-3-thread-1] 2012-03-22 09:15:20,967 Error getting realtime node details
java.lang.RuntimeException: Agent is failed, needs restart
at clojure.lang.Agent.dispatch(Agent.java:225)
at clojure.core$send_off.doInvoke(core.clj:1601)
at clojure.lang.RestFn.invoke(RestFn.java:464)
at opsagent.opsagent$setup_conn$send_message__3661.invoke(opsagent.clj:103)
...

But I'll mark this topic resolved and look at this problem separately. I might not have a port number correct or something. Thanks again for your help.

Hi,
I am replaying to this post because I cannot open a new one (how is this possible?)
I have the same problem to run opscenter 2.1 on Fedora 16.
I don't have root priviliges so I downloaded tarball. But I've got the same exception. I've Python 2.7 installed.
And in my configuration I have this line
+PY_VER=$($PYTHON -c "import platform; v = platform.python_version(); print v[:v.index('.', 2)]")
instead of this one:
-PY_VER=$($PYTHON -c "import sys; v = sys.version; print v[:v.index('.', 2)]")
(probably its becouse the fix that you mentioned.
Any clues?

lotka,

Fedora isn't a supported distro for OpsCenter at this time. It's possible that it will run on Fedora with some modification, but I have no idea if it actually will.

If you want to try, edit bin/opscenter and replace the line

PY_DISTRO="./lib/py-redhat/${PY_VER}/shared/${PY_ARCH}:./lib/py-redhat/${PY_VER}/${VER}/${PY_ARCH}"

with

PY_DISTRO="./lib/py-redhat/2.7/shared/amd64:./lib/py-redhat/2.7/6/amd64"

That assumes you're using a 64 bit system. If not, replace amd64 with i386. Hopefully that might work, but if not, there's not much else we can do.
