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.

this is my first ever post on stackoverflow
Im sending json logs from filebeat to logstash to opensearch to grafana
and everything is working perfectly (if it comes to integer data)
i can even see that opensearch receives my string fields and boolean fields and even reads them.
but when i want to make a dashboard to visualize some strings and booleans, it only finds my integer fields
Can someone help me visualize Strings on grafana and not only numbers.
this is an image of what i can see when i try to select data, i only see the number field names
thanks andrew, now i see this, but i want to only see 1 field
and not all of them
logs added to grafana
You can try using the Logs panel
And an example of how I use - the request is something like this:
{namespace=~"$namespace", stream=~"$stream", container =~"$container"} |= "$query"
But I'm using fluent-bit + loki
I'm missing some index patterns in Kibana and I've been trying to figure out why this is the case. I have installed logstash, elasticsearch and kibana and started the services. How do I get logstash, apache-access etc to show in this section? Only filebeat shows.
I've used the CURL command for the localhost and port to see the indices and only kibana and filebeat are shown there are and apache-access and logstash are no where to be seen.
Can anyone guide me in the right direction to resolving this and being able to see 'logstash' and 'apache-access' under the patterns section.
Data is being saved inside indices in Elasticsearch cluster, in Kibana you can define index-patterns to show multiple indices at the same time.
When you look in the left menu of your screenshot you'll find a menu item called "Index Management", all indices will be shown there, here you'll find the name of the indices that exist in your Elasticsearch cluster.
An index pattern in Kibana is just a (wildcarded) pattern to allow you to see the data.
On the top right of your screenshot you see the button "+ Create Index Pattern", by clicking there you can define a new pattern which will live next to the existing one (filebeat-*).
Once you defined a second one, you'll be able to define which one is the default one chosen when you open Kibana and a dropdown will be available on your discover page in Kibana with the active index-pattern for your discovery at that time.
tash
So in short, press the "create index pattern" button twice entering once logstash* as the pattern and once apache-access* as pattern.
as I am new to the ELK technology i need some help on this. I've a requirement in which i need to get log location(More than 1 for sure)s from a DB table and pass those values in logstash input to view the data in kibana. Can you please share some examples from which I'll refer and go ahead .
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.
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.
