I am configuring monolog logging in laravel and I am wondering if there is a way to specify threshold for log file? For example in log4php you have maxFileSize property. Is there some way to do it with monolog?
(Check this for how to configure custom monolog: Configuring Custom Logging in Laravel 5 )
According to documentation laravel supports out of box only single, daily, syslog and error log logging modes.
I am wondering if is there way to use something between single and daily? I do not want to have daily log files and also do not like idea to have one big file. I would like to have possibility to specify threshold. For example 20 Mb and when this size is reached then to create new log file.
Does anybody has solution for that?
Use a proper log rotation facility that is available in your OS of choice for that.
On linux machine - logrotate
On Mac OS X - newsyslog
RotatingFileHandler in the monolog package, which Laravel uses for logging, intended to be just as a workaround.
Stores logs to files that are rotated every day and a limited number of files are kept.
This rotation is only intended to be used as a workaround. Using logrotate to
handle the rotation is strongly encouraged when you can use it.

I am using Springboot version 2.7 and trying to configure the log pattern to be daily rolling.
I am currently using just the application properties file to configure the logging as that's the preference.
I added the following line in the properties file but does not seem to work
logging.logback.rollingpolicy.file-name-pattern=myservice-%d{yyyy-MM-dd}.log
Any clues what I may be missing?
Also, is there a way to check daily log rolling without having to wait for EOD :)
First, you have to specify the file name:
logging.file.name=myservice.log
then you can use the rolling file name pattern
logging.logback.rollingpolicy.file-name-pattern=myservice-%d{yyyy-MM-dd}.log
To force the file change you could set the size to something small
logging.logback.rollingpolicy.max-file-size=100K
To specify the directory you must set this property
logging.file.path=/var/logs
The documentation can be found here:
https://docs.spring.io/spring-boot/docs/current/reference/html/features.html#features.logging
I start Solr in the foreground like so C:\solr-8.10.1\bin\solr start -p 8983 -m 1536m -f -v
It shows a command window and it logs a massive amount of DEBUG info, which I don't need.
I want to reduce the amount of logging here, and I found this: https://solr.apache.org/guide/8_5/configuring-logging.html
This seems exactly like what I need for my scenario:
I have many cores, each with their own solrconfig.xml:
C:\solr-8.10.1\server\solr\core1
C:\solr-8.10.1\server\solr\core2
C:\solr-8.10.1\server\solr\core3
C:\solr-8.10.1\server\solr\coreX
I don't want to have to make the logging changes to each core separately but 1 global setting that applies to all
I don't use Solr API, I want to be able to change settings via config files
I want ERRORS to be logged, and also any slow queries
After reading the tutorial then I decided I need to:
start Solr using solr start -p 8983 -m 1536m -f -q
Need to add an element <slowQueryThresholdMillis>1000</slowQueryThresholdMillis>
However, it's that last part where I have questions. I see a reference made to so called configsets, but I have no idea if that's the place where I need to configure my global settings.
I inspected the sample files, e.g. \solr-8.10.1\server\solr\configsets\sample_techproducts_configs\conf\solrconfig.xml
But I can't figure out if that's the right config file or how it would even apply to all other cores without any reference to the other cores.
I've had a look at these already, but they seem to want to handle things via code, whereas I'm looking for a file configuration:
configure Logger via global config file
Use of readConfiguration method in logging activities
How to create a daily rolling log file in Websphere Liberty? I want the name of the log file to have YYYYMMDD format.
Currently I'm only able to limit the max file size, max file and a static naming of messages.log and disable consolelog.
<logging consoleLogLevel="OFF" maxFileSize="1" maxFiles="3" messageFileName="loggingMessages.log"/>
https://www.ibm.com/support/knowledgecenter/SSEQTP_8.5.5/com.ibm.websphere.wlp.doc/ae/rwlp_logging.html
WebSphere Liberty does not currently have the ability to schedule log file rotation like traditional WAS. You can request this feature using the RFE site.
Alternatively, you could use an approach like Bruce mentioned - perhaps using a cron job to restart the server at midnight.
You might also consider configuring Liberty's binary logging. This will create a binary log file that can be queried to produce actual log files (with filtering options, etc.). It does have some time-based options. More info here.
Hope this helps, Andy
Probably not the answer you want, but if you restart the server it will roll the log.
I am quite new for log4j2 logger and my requirement to write a log from application server and web server.
I am having two different environment on which J BOSS server is deployed.
Now I am having a log file on web server environment which is writing logs for errors and I want to write logs from application server also in same file.
Please suggest.
If you want the logs to be integrated together you should use a solution like Splunk or Elastic Search/Logstash/Kibana (ELK).
When you try to write to a file from 2 different processes your file will get corrupted unless you use file locking. However, your throughput will decrease significantly and it isn't supported for rolling files. So the best approach is to send the logs to a single process where they can be aggregated.
I have 10 applications they have same logic to write the log on a text file located on the application root folder.
I have an application which reads the log files of all the applicaiton and shows details in a web page.
Can the same be achieved on Windows Azure? I don't want to use the 'DiagnosticMonitor' API's. As I cannot change logging logic of application.
Thanks,
Aman
Even if technically this is possible, this is not advisable as the Fabric Controller can re-create any role at a whim (well - with good reasons, but unpredictable none-the-less) and so whenever this happens you will lose any files stored locally on a role.
So - primarily you should be looking for a different place to store those logs, and there are many options, but all require that you change the logging logic of the application.
You could do this, but aside from the issue Yossi pointed out (the log would be ephemeral; it could get deleted at any time), you'd have a different log file on each role instance (VM). That means when you hit your web page to view the log, you'd see whatever happened to be on the log on that particular VM, instead of what you presumably want (a roll-up of the log files across all VMs).
Windows Azure Diagnostics could help, since you can configure it to copy log files off to blob storage (so no need to change the logging). But honestly I find Diagnostics a bit cumbersome for this. It will end up creating a lot of different blobs, and you'll have to change the log viewer to read all those blobs and combine them.
I personally would suggest writing a separate piece of code that monitors the log file and, for each new line, stores the line as an entity (row) in table storage. This bit of code could be launched as a startup task and just run continuously as a separate process (leaving everything else unchanged). Then modify the log viewer to read the last n entities from table storage and display them.
(I'm assuming you can modify the log viewer even if you can't modify the apps that log to the file.)
What about writing logs to something like azure storage table? Just need to define unique ParitionKey/RowKey, then you can easily retrieve the log for the web page.
