We had our own custom logger in a C# program and now are trying to port to log4net.
In our app, there is further structure to what would normally go into %message. It may contain requestid, associated users, and other structure where requestid and user have internal significance to the program.
The hope is to ultimately be able to search on the fields inside %message, say requestid so we can collect all log entries with the same requestid for example.
Does log4net assist in anyway in creating own custom fields? The reason we ask is that currently the entire %message is logged as one string by default.
Any other suggestions on how to provide further formatting for %message? Otherwise we would have to pre-format %message inside our own code as, say, a CSV format
You can use event context to add additional structured data to a log entry:
http://www.beefycode.com/post/Log4Net-Tutorial-pt-6-Log-Event-Context.aspx
Depending on what kind of information you want to log you may need to create a wrapper that accepts additional parameters or else you have to write verbose code like this:
log4net.ThreadContext.Properties["myInformation"] = yourAdditionalInformation;
log.Info("info message");
Other information can be calculated and thus can be set once (for instance on application start up). Have a look at the calculated context properties in the above tutorial.

We have an ELK setup and the Logstash is receiving all the logs from the Filebeat installed on the server. So when I open Kibana and it asks for an index I put just a * for the index value and go to the Discover tab to check the logs and it shows each line of the log in a separate expandable section.
I want to be able to group the logs based on the timestamp first and then on a common ID that is generated in our logs per request to identify it from the rest. An example of the logs we get :
DEBUG [2018-11-23 11:28:22,847][298b364850d8] Some information
INFO [2018-11-23 11:27:33,152][298b364850d8] Some information
INFO [2018-11-24 11:31:20,407][b66a88287eeb] Some information
DEBUG [2018-11-23 11:31:20,407][b66a88287eeb] Some information
I would like to see all logs for request ID : 298b364850d8 in the same drop down given they are continuous logs. Then it can break into the second dropdown again grouped by the request ID : b66a88287eeb in the order of timestamp.
Is this even possible or am I expecting too much from the tool?
OR if there is a better strategy to grouping of logs I'm more than happy to listen to suggestions.
I have been told by a friend that I could configure this in logstash to group logs based on some regex n stuff but I just don't know where and how to configure it to fo the grouping.
I am completely new to the whole ELK stack to bear with my questions which might be quite elementary in nature.
Your question is truly a little vague and broad as you say. However, I will try to help :)
Check the index that you define in the logstash output. This is the index that need to be defined Kibana - not *.
Create an Index Pattern to Connect to Elasticsearch. This will parse the fields of the logs and will allow you to filter as you want.
It recommend using a GUI tool (like Cerebro) to better understand what is going on in you ES. It would also help you to get better clue of the indices you have there.
Good Luck
You can use #timeStamp filter and search query as below sample image to filter what you want.
Purpose: Track privileged user activity in Windows logs.
Logic:
If logon event contains token_elev %1937 or %1938 save the logon_id (hex value) to a dynamic priv_logons list.
For subsequent events, if the logon_id in the event matches one of the entries in priv_logons list, add a 'privileged' tag to the event.
When receiving a logoff event with one of the logon_ids saved in priv_logons list, remove it from the list.
Is this doable in LogStash? If yes, how?
Not with Logstash alone.
Logstash does not maintain internal states or data objects in between events, it is simply a parsing engine.
Logstash may help you create this kind of solution by doing the parsing work and then passing clean and sensible data to a program which performs the logic you are looking for.
I am automating Sharepoint list testing, filling up some field with values,
and like to save data I supplied to the field after.
Is there a way to automate saving the field value in a excel or csv?
In order to keep it simple, I would create two recordings and write to a text file (csv).
The first one would get the text values from the desired fields and return them in bound variables using Ranorex GetValue action.
The second recording would write the content of the bound variables to a text file, separating fields with ',' (or any other character that is suitable for the kind of data that is present in the fields) in a user code function.
If you have no idea how to write to a file in .NET, take a look at System.IO.File.AppendAllLines or similar functions.
You could also combine the 2 recordings in one, but then, re-useability would be limited the scope of the SharePoint page you are testing.
Do not forget that since Ranorex is using the .NET framework, you have access to all the functions provided by the framework in user code. With Ranorex, the usual question is not ask if something is possible. The real question is "how can it be done" and is the solution simple enough for testers to be able to use it!
Hope this helps!
I'm using the snapshot version of apache chainsaw http://people.apache.org/~sdeboy and I just need to read in a text log file. It works fine when I'm reading in keyword columns ex: LEVEL, MESSAGE ect... but when I want to add in a user defined column, it doesn't work.
To read in the text file, I use TIMESTAMP: LOGGER: LEVEL : MESSAGE : PROP(TIER) as my log format where tier is my user defined property.
User-specified properties via PROP work fine in general - I'm pretty sure the issue is that the MESSAGE field is not the last field in your log format.
Can you reformat your log format to make MESSAGE the last field?
If you can't, I'd try replacing the MESSAGE entry in your log format with a user-defined property like PROP(TEXT).
Either option may work for you.
I am implementing logging in our application using ETW.
I used ecmangen.exe to create the manifest with a set of custom events, templates, tasks and keywords.
I used mc.exe to compile and generated corresponding C# class for use in my code.
I used this generated class in our code to emit events.
I imported the manifest via wevtutil and captured events via event trace session (Win2K8R2 - Performance - Data Collector Sets)
When I open the generated trace file via Event Viewer, I see the events I was expecting. But I found that the custom task categories and keywords are showing in their numeric form, instead of their names.
Should these values be translated? Or am I going about this the wrong way?
