Can anyone explain how to enable debug logging in Eucalyptus 4.0.0 properly?
I set LOGLEVEL="DEBUG" in /etc/eucalyptus/eucalyptus.conf
Then I restarted everything but logs still only show INFO, WARN and ERROR.
You're on the right track. Setting LOGLEVEL="DEBUG" in eucalyptus.conf is valid for C-based components, and Java-based components which have not yet fully bootstrapped. When you set DEBUG in eucalyptus.conf, you'll need to restart the affected components on just that machine. So for example, on the NC, you would need to issue a restart, eg, "service eucalyptus-nc restart" in order to pick up the new value.
For the Java components, in particular after they've bootstrapped, you set the cloud-wide PROPERTY thusly:
euca-modify-property -p cloud.euca_log_level=DEBUG
and the output will tell you what the property was, and what is has become, if done correctly.
For example:
# euca-modify-property -p cloud.euca_log_level=DEBUG
PROPERTY cloud.euca_log_level DEBUG was INFO
Once you've set that, you're good to go. No need to restart any of the Java components, anywhere in the cloud.

I have an Ansible script to update and maintain my WildFly installation. One of my tasks in this setup is managing the MySQL-driver and in order to perform an update on that driver, I have to first disable the application that uses that driver, before I can replace the it and set up all my datasources anew.
My CLI script starts with the following lines:
if (outcome == success) of /deployment=my-app-1.1.ear:read-resource
deployment disable my-app-1.1.ear
end-if
My problem is that I am here very depending on the actual name of the application and that name can change over time since I have my version information in there.
I tried the following:
set foo=`ls /deployment`
deployment disable $foo
It did not work since when I look at foo I see that it was not my-app-1.1.ear but ["my-app-1.1.ear"] -- so I feel that I might be going in the right direction, even though I have not got it right.
I'm new to Axon and Docker and I would like to start axon server in Docker using developmnent mode in order to clear events as I'm in the process of building a system and my events and commands change often.
I read on Axon documentation that a certain property axoniq.axonserver.devmode.enabled (defaults to false) has to be set. I also know that Axon uses spring boot, so I guess I would need to somehow access the axonserver.properties on Docker, but here is the problem, i don't know how.
I would be thankful if anyone could explain how to change this configuration.
Fortunatelly Axon has been publishing blogs about running axon-server and one of them, they teach how to run it on docker =)

The important part, in your case, is here:
A third directory, not marked as a volume in the image, is important for our case: If you put an “axonserver.properties” file in “/config”, it can override the settings above and add new ones:
Which means, you can create your axonserver.properties in this directory with the desired property (axoniq.axonserver.devmode.enabled=true) and it will pick it up from there!
On the other hand, you can also set the environment variable: AXONIQ_AXONSERVER_DEVMODE_ENABLED to true.
Hope it helps.
I tried to play with LowCardinality setting, I got a message saying that this is an experimental feature and I have to SET allow_experimental_low_cardinality_type = 1 in order to use it.
I executed this command inside clickhouse-client and then I restarted the server. But I got
clickhouse-server.service: Unit entered failed state
Now I am trying to find out how to disable this setting and make my clickhouse-server start again.
Can you help with this please ?
PS: The version I use is the 18.12.17 and I installed it on Linux Ubuntu 16.04
ClickHouse has different layers for settings. If you used SET <setting> = <value> then you set it for current session. You don't need to restart ClickHouse. Please, take a look here.
I suppose you faced with another problem during starting your server. There a bunch of reasons why. So, firstly try to recollect what were done in configs since last restart (because you have just applied changes by restarting server).
Digging into logs also an awesome idea. Don't hesitate to check other similar issues on github.com, for example like this one
I'm looking to start Spring XD in distributed mode (more specifically deploying it with BOSH). How does the admin component communicate to the module container?
If it's via TCP/HTTP, surely I'll have to tell the admin component where all the containers are? If it's via Redis, I would've thought that I'll need to tell the containers where the Redis instance is?
Update
I've tried running xd-admin and Redis on one box, and xd-container on another with redis.properties updated to point to the admin box. The container starts without reporting any exceptions.
Running the example stream submission curl -d "time | log" http://{admin IP}:8080/streams/ticktock yields no output to either console, and not output to the logs.
If you are using the xd-container script, then the redis.properties is expected to be under "XD_HOME/config" where XD_HOME points the base directory where you have bin, config, lib & modules of xd.
Communication between the Admin and Container runtime components is via the messaging bus, which by default is Redis.
Make sure the environment variable XD_HOME is set as per the documentation; if it is not you will see a logging message that suggests the properties file has been loaded correctly when it has not:
13/06/24 09:20:35 INFO support.PropertySourcesPlaceholderConfigurer: Loading properties file from URL [file:../config/redis.properties]
I've compiled and trolled around the quickfix ( http://www.quickfixengine.org ) source and the examples. I figured a good starting point would be to compile (C++) and run the 'executor' example, then use the 'tradeclient' example to connect to 'executor', and send it order requests.
I created two seperate session files one for the 'executor' as an acceptor, and one for the 'tradeclient' as the initiator. They're both running on the same Win7 pc.
'executor' runs, but tradeclient can't connect to it, and I can't figure out why. I downloaded Mini-fix and was able to send messages to executor, so I know that executor is working. I figure that the problem is with the tradeclient session settings. I've included both of them below, I was hoping someone could point out what's causing them to not communicate. They're both running on the same computer using port 56156.

Update: Thanks for the resonses... Turns out that my logfile directories didn't exist. Once I created them, they both started communicating. Must have been some logging error that didn't throw an exception, but disabled proper behavior.
Is there an error condition that I should be checking? I was relying on exceptions, but that's obviously not enough.
It doesn't seem to be config, check that your message sequence numbers are in synch, especially since you've been connecting to a different server using the same settings.
Try setting the TargetCompID and SenderCompID on the acceptor to *
