I am just started exploring about the Elasticsearch + Kibana + Logstash combined as my requirement of integration this with other tool chains.
I have tried to successfully downloading of ElasticSearch & Kibana from official websites.
https://www.elastic.co/downloads/kibana
https://www.elastic.co/downloads/elasticsearch
And I am able to start the ElasticSearch as well.
When I go to browser to access this it is asking for me to enter credentials.
I saw lots of tutorials on youtube no one faced this problem.
Need to know what settings of configuration needs to apply here ?
My OS is : Windows-10
Thanks in advance !!
Adding below two lines in \elasticsearch-8.2.2\config\elasticsearch.yml
# Enable security features
xpack.security.enabled: true
xpack.security.enrollment.enabled: true
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 have problem with rabbitmq logs in server because the file is very large when my shovels could not connect to destination server .
I try to set rabbitmq.config with this
[
{rabbit, [{log_levels,[{connection, error}]}]}
].
and this
[{rabbit, [
{log, [
{file, [{enabled, false}]}
]}
]}].
but after setting config with this, log files are still creating in this name: RABBIT~1.LOG and RABBIT~2.LOG
Can anyone help me set config to disable all log files or set config to rotate log files with date ?
My RabbitMQ version is 3.6.14 and Erlang version is 18.1
Thank you very much.
The RabbitMQ team monitors the rabbitmq-users mailing list and only sometimes answers questions on StackOverflow.
You should upgrade to a more recent version of RabbitMQ and Erlang. The 18.X Erlang series is known to have issues.
RabbitMQ 3.7.X uses the lager library which supports being disabled completely if you wish to do so. But that is a very bad idea because you won't have any visibility into your system if an error arises.
I recommend enabling log rotation in lager instead. See the "Logging to a File" section in this document:

I've had RabbitMQ 3.2.1 (Erl OTP 16B02 x64) running on Win 2008R2, one day it started to return nodedown error. I decided to reinstall RabbitMQ, I've removed Rabbit and Erlang enviriment, cleaned db folder in RABBITMQ_BASE, removed all erlang cookies and RABBITMQ_NODENAME / PORT variables. Intalled RabbitMQ 3.5.4 Erlang OTP18 x64 as admin....but still I'm not able to manage service via command promt, it gives me following output:
I've already seen some post on this error (Post1 , Post2 ) but, as I see right now all that they are suggesting is reinstall RabbitMQ and to be careful with Erlang cookies, and I've cleaned system completely after uninstalling previous version. Still, any suggestions appreciated.
Thanks.
UPD
Funny thing - I've noticed that db folder in RABBITMQ_BASE is empty, so it is empty in %USERPROFILE%\AppData\Roaming\RabbitMQ... I thought it must create node structure there on service first start...
It's telling you that it is trying to connect to a node with name 'rabbit', and it is telling you that there is a node running with a name of 'RabbitMQ'.
Presumably 'RabbitMQ' is indeed your RabbitMQ node? Perhaps your new installation changed the name of the node, or maybe you were using a non default node name before that has been partially reset? Or maybe something else... Either way, I know you said you cleaned it, but there's a definite mismatch in the node name being used by your server and the rabbitmqctl client.
See RabbitMQ configuration for details on how to check and change your configuration (for UNIX and Windows), or try telling rabbitmqctl to use a different node name (this is -n on UNIX, not sure on Windows).
We (the RabbitMQ team) already saw this behavior, but couldn't reproduce it so far. What we discovered is that for unknown reasons, the Windows service is installed without its parameter, in particular, the node name (rabbit#<hostname>) is missing and Erlang (or Windows, I don't know) picks the service name as the node name (RabbitMQ#<hostname>).
rabbitmqctl fails to contact this node because it expects rabbit#<hostname> by default. But anyway, the node is not working properly.
The workaround we know is to remove and reinstall the Windows service.
I don't have access to a WebSphere console, but I need to check if encryption is enabled between the console and appserver connection. The docs I have come across are almost all console related, and I am unable to find what I need. Where would I be able to find this config file setting?
Thanks
I suppose you are looking for WCInboundAdminSecure : it should be located in :
{WAS_HOME}/config/cells/{your cell}/nodes/{your node}/servers/{your server}/server.xml
