The Object Logger is a logging framework for logging Objects to a data source. It also contains some nice functions to read from the log file. ##How to use it?. The ObjectLogger is the entry point and requires an IDataSource to write the data to. One ObjectLogger will log all Objects in the same way to one file. Objects are logged with a timestamp, so in actual fact the object that is logged is a TimestampedObject which essentially just wraps the logged Object and contains a timestamp of when it was created. There is one implementation of IDataSource available for use out of the box and that is the FileSystemDataSource which, you guessed it, writes to the file system. This data source takes a filename and ITimestampedObjectSerialiser to serialise the Object to the file. The default filename is the simple name of the generic type of the ObjectLogger. The default ISerialiser is the TimestampedObjectJsonSerialiser. The FileSystemDataSource can also take an IRollingStrategy to make decisions on when to roll the log file. By default the DailyRollingStrategy is used, but you can choose to use a MinuteRollingStrategy if you prefer. The IDataSource also contains methods to read the Objects from the log file. The getAll() method and its various overloaded counterparts allow the caller to read in all or some of the Objects from the file. THe Objects are returned in a TimestampedObjectSet which again provides the caller with more ways to retrieve the data they are looking for. Say we have an Account object that we want to log as JSON to the filesystem. This is how we would do it.

QUESTION
It is difficult to put what I need in a sentence but the code below pretty much explains it:
I have my logging class in a separate file (log_file) as below, and a logger object defined there:
...ANSWER
Answered 2022-Mar-31 at 21:12Yes, you can achieve what you want, actually is well documented under: https://docs.python.org/3/howto/logging.html
There is a parameter where you can provide a dictionary with additional values to your log format.

QUESTION
MySql 5.5 has a few logging option, among which the "Binary Logfile" with Binlog options which I do not want to use and the "query log file" which I want to use.
However, 1 program using 1 table in that database is filling this logfile with 50+Mb per day, so I would like that table to be excluded from this log.
Is that possible, or is the only way to install another MySql version and then to move this 1 table?
Thanks, Alex
...ANSWER
Answered 2022-Mar-29 at 20:14There are options for filtering the binlog by table, but not the query logs.
There are no options for filtering the general query log. It is either enabled for all queries, or else it's disabled.
There are options for filtering the slow query log, but not by table. For example, to log only queries that take longer than N seconds, or queries that don't use an index. Percona Server adds some options to filter the slow query log based on sampling.
You can use a session variable to disable either slow query or general query logging for queries run in a given session. This is a dynamic setting, so you can change it at will. But you would need to change your client code to do this every time you query that specific table.
Another option is to implement log rotation for the slow query log, so it never grows too large. See https://www.percona.com/blog/2013/04/18/rotating-mysql-slow-logs-safely/
QUESTION
I have a kubernetes cluster that's running datadog and some microservices. Each microservice makes healthchecks every 5 seconds to make sure the service is up and running. I want to exclude these healthcheck logs from being ingested into Datadog.
I think I need to use log_processing_rules
and I've tried that but the healthcheck logs are still making it into the logs section of Datadog. My current Deployment looks like this:

I would like to send this message also to another function, which is a Telegram function called SendTelegramMsg()

send a message through logger.info("Start")

function which is inside setup_logger
function?

ANSWER
Answered 2022-Jan-06 at 15:59Picking up the idea suggested by @gold_cy: You implement a custom logging.Handler
. Some hints for that:
- for the handler to be able to send message via a bot, you may want to pass the bot to the handlers
__init__
so that you have it available later emit
must be implemented by you. Here you'll want to callformat
which gives you a formatted version of the log record. You can then use that message to send it via the bot- Maybe having a look at the implementation of
StreamHandler
andFileHandler
is helpful as well

I am using the built in Python "logging" module for my script. When I turn verbosity to "info" it seems like my "debug" messages are significantly slowing down my script.
Some of my "debug" messages print large dictionaries and I'm guessing Python is expanding the text before realizing "debug" messages are disabled. Example:

QUESTION
Running Xcode 13 I see the following log when launching my iOS app in the Simulator:
Writing analzed variants.
Note that this is, hopefully, a misspelling of the log:
Writing analyzed variants.
What is causing this log noise? Is something in my code triggering it?
How can I hide this "Writing analzed variants." Xcode log?
...ANSWER
Answered 2022-Jan-13 at 17:02According to Quinn “The Eskimo!” at Apple Developer Technical Support, this message is Xcode log noise and can be ignored.
An Apple bug report should be filed to help flag and silence the log.
It’s important to keep an eye on log messages and fix any obvious problems they call out. However, if you see a log message that’s not obviously your fault, it could just be log noise.
There are two criteria you should apply here:
- Is the log message associated with a specific failure? That is, when you see the log message, do you also see other problems?
- Is the log message written in terms you understand? That is, does it reference APIs or data that you’re using?
If the answer to both of these questions is “No”, it’s reasonable to conclude that the log message is just noise and you can ignore it. If you find it to be particularly irksome, file a bug report requesting that it be silenced.
QUESTION
I have implemented a POC and have used slf4j for logging. The zero day vulnerability issue in log4j, did that also impact slf4j logs?
...ANSWER
Answered 2022-Jan-03 at 22:16It depends. Slf4j is just an api, that can be using behind any of its implementions, being log4j just one. Check which one is using on the back, and if this is log4j and between versions 2.0.0 and 2.15.0 (2.15.0 is the one with the fix, versions 1.x are not affected) you should update it (if it is exposed to users directly or indirectly)

Install object-logger
You can use object-logger like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the object-logger component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
