I'm not sure why this question was not asked before. But I want to check current value of a running uwsgi configuration options, such as socket-timeout or uwsgi_read_timeout. The reason being is that by checking the current values, I can confirm the values set in config files
/etc/nginx/conf.d/default.conf
/etc/uwsgi.d/main.ini
actually take effect. this is to avoid the situation where typos in configuation file prevent the value being applied.
Can:
uwsgi --show-config
or,
uwsgi --get
be used for this purpose? if so, how to specify the uwsgi instance I want to check config values for? what is the complete syntax?

Documentation for MariaDB says clearly how to set up server defaults like charset and collation. So I opened my Mariadb console and run:
SET character_set_server = 'utf8mb4';
SET collation_server = 'utf8mb4_slovak_ci';
Consoles wrote OK.
Then I restart the server, but as I tried to create new database there are still the same latin2 charset and swedish collation.
I do it automatically via Symfony cosole command
php bin/console doctrine:database:create
What is wrong with that? I did it like documentation says.
SET character_set_server changes the character set for the current connection.
SET global character_set_server changes the character set globally for each new connection.
However if you restart your server the default character sets for server will be read from the configuration file. If the configuration file doesn't specify character set, then defaults will be used. So for making your settings permanent, you have to change the character sets in your configuration file (https://mariadb.com/kb/en/configuring-mariadb-with-option-files/)
First, run the SHOW VARIABLES like "%collation%"; to show you the current configs.
To change collation_server setting, you have to use the keyword GLOBAL and therefore your statement will be SET GLOBAL collation_server = 'utf8mb4_slovak_ci';
We're got a pre-existing rsyslog config file which is working for papertrail e.g.
/etc/rsyslog.d/20-papertrail.conf which has
*.* #logs4.papertrailapp.com:44407
However we've got a couple of NGINX websites on the server so would like to have it also monitor their error logs.
The paths to them are:
/var/log/nginx/www.website-one.com-error.log
/var/log/nginx/www.website-two.com-error.log
/var/log/nginx/www.website-three.com-error.log
However this /var/log/nginx also contains a bunch of .log files which we do not want to monitor e.g.
/var/log/nginx/error.log
/var/log/nginx/access.log
/var/log/nginx/error.log1
/var/log/nginx/nginx.log
In my head we need to add something like...
/var/log/nginx/*-error.log
And make sure they pipe to the papertrail url as well.
However I'm struggling to decipher the rsyslog documentation to figure out how to do this.
Thanks!
In rsyslog documentation it seems that you can use wildcards in files.
File
The file being monitored. So far, this must be an absolute name (no macros or templates). Note that wildcards are supported at the file name level (see WildCards below for more details).
WildCards
Before Version: 8.25.0
Wildcards are only supported in the filename part, not in directory names.
/var/log/*.log works.
/var/log/*/syslog.log does not work.
Since Version: 8.25.0
Wildcards are supported in filename and paths which means these samples will work:
/var/log/*.log works.
/var/log/*/syslog.log works.
/var/log/*/*.log works.
All matching files in all matching subfolders will work. Note that this may decrease performance in imfile depending on how many directories and files are being watched dynamically.
If you want to forward your vhosts logs you can change configuration directly in NGINX vhosts configuration, you should change/add access_log and error_log policies as explained here or use custom facilities to forward your logs (using rsyslog).
HOW TO DO IT USING RSYSLOG?
Create a new custom file in /etc/rsyslog.d/nginx_custom.conf:
module(load="imfile" PollingInterval="1") #needs to be done just once
# File 1
input(type="imfile"
File="/var/log/nginx/www.website-*.com-error.log"
Tag="websites"
Facility="local0")
local0.* #logs4.papertrailapp.com:44407
#Just to test that logs are forwarded, comment the line once you've tested it
local0.* /var/log/test.log
And restart rsyslog service
NOTE: Line local0.* /var/log/test.log is just to test that you can see forwarded logs into your local server, comment this line after you've tested that everything works.
I want to send my weblogic log to syslog. here is what I have done so far.
1.Included following log4j.properties in managed server classpath -
log4j.rootLogger=DEBUG,syslog
log4j.appender.syslog=org.apache.log4j.net.SyslogAppender
log4j.appender.syslog.Threshold=DEBUG
log4j.appender.syslog.Facility=LOCAL7
log4j.appender.syslog.FacilityPrinting=false
log4j.appender.syslog.Header=true
log4j.appender.syslog.SyslogHost=localhost
log4j.appender.syslog.layout=org.apache.log4j.PatternLayout
log4j.appender.syslog.layout.ConversionPattern=[%p] %c:%L - %m%n
2. added following command to managed server arguments -
-Dlog4j.configuration=file :<path to log4j properties file> -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.Log4JLogger -Dweblogic.log.Log4jLoggingEnabled=true
3. Added wllog4j.jar and llog4j-1.2.14.jar into domain's lib folder.
4.Then, from Admin console changed logging information by doing the following. "my_domain_name"--->Configuration--->Logging--->(Advanced options)-->Logging implementation: Log4J
Restart managed server.
I used this as refernce. But didnt get anaything in syslog(/var/log/message). What am I doing wrong?
I would recommend a couple items to check:
Remove the space in DEBUG, syslog in the file
Your last two server arguments have a space between the - and the D so make sure that wasn't just a copy and paste error in this post.
Double check that the log files are in the actual classpath.
Double check from a ps command, that the -D options made it correctly into the start command that was executed.
Make sure that the managed server has a copy of the JARs correctly as they would get synchornized from admin during the restart.
Hopefully something in there will help or give an idea of what to look for.

I figured out the problem. My appender was working fine, the problem was in rsyslog.conf. Just uncommented following properties
# Provides UDP syslog reception
#$ModLoad imudp
#$UDPServerRun 514
We were appending the messages, but the listner was abesnt, so it didnt knew what to do with it.
and from *.debug;mail.none;authpriv.none;cron.none /var/log/messages it figures out where to redirect any (debug in this case) information to messages file.
Showing currently applied configuration values
In v2.0+ of Riak there is a new command option: riak config effective
Which I read as it would tell you the current running values of riak.
At any time, you can get a snapshot of currently applied
configurations through the command line. For a listing of all of the
configs currently applied in the node
Config changes applied only on start of each node?
In multiple locations in Riak documentation there is reference like:
Remember that you must stop and then re-start each node when you
change storage backends or modify any other configuration
Problem:
However when I made a change to a setting (I've tested this in both riak.conf and advanced.conf), I see the newest value when running: riak config effective
ie:
Start node: riak start
View current setting for log level: riak config effective | grep log.console.level
log.console.level = info
Change the level to debug (something that will output a lot to console.log)
Re-run: riak config effective | grep log.console.level, we get:
log.console.level = debug
Checking the console log file for debug: cat /var/log/riak/console.log | grep debug give no results (indicating the config change has not been applied)
So the question is, how can I retrieve and verify what config setting each Riak node is running under?
When Riak starts, it creates two files: 'app..config' and 'vm..config'. The default location is in a 'generated.configs' directory under the platform data directory (usually /var/lib/riak).
These files will contain the settings that were in place when Riak was started. The command riak config effective processes the current riak.conf and advanced.config files.
I am using nginx as web server and when I do phpinfo(); it uses /etc/php5/fpm/php.ini
Now in my php code I am trying to set file upload size and max file uploads using following code.
ini_set('max_file_uploads', "50");
ini_set('upload_max_filesize', '250M');
But when I do ini_get('max_file_uploads') and echo the value it shows the default value as 20, infact I am not able to change any of the ini values in run time using ini_set().
Any ideas on how to change these values in run time using php code?
Thanks.
Not all PHP ini directives can be changed at runtime (via ini_set). See the file uploads section of the PHP manual and the definition of the changeability values, which are PHP_INI_SYSTEM and PHP_INI_PERDIR for your desired settings, neither of which can be set at runtime.
To get these settings in only one part of your app, you'll likely need to compromise and set max_file_uploads setting globally in your php.ini file (since it is PHP_INI_SYSTEM), and then use your favorite per-directory config mechanism (.htaccess, .user.ini (in >5.3), etc) to set upload_max_filesize for that particular part of your app. See here for good instructions.
