I want to ask that how to convert below time formats in logstash.
9:48:42 to 09:48:42
9:8:42 to 09:08:42
9:48:2 to 09:48:02
9:8:2 to 09:08:02
Thanks for answering
I have solved my question with this way;
Creating input codec plugin and check if it starts without "0" then
put it in front of the message (event) with ruby

this is the timestamp generated by python written logs.
I hav tried
SYSLOGTIMESTAMP, DATESTAMP_EVENTLOG, DATESTAMP_RFC2822,TIMESTAMP_ISO8601
and many more. Can anyone please provide the correct grok format for this.
If not possible how can i use this as a timestamp
You can try these Groks:
\[(?<timestamp>%{MONTHNUM}-%{MONTHDAY} %{TIME})\]
or
\[(?<timestamp>[^\]]+)\]
I am trying to display just the time of the last logon of a user.
The goal is to display the time just like
date "+d% %B%t%Y"
would.
I tried:
last -n1 --time-format "+d% %B%t%Y"
but it keeps telling me that it is an unknown time format.
I also tried the ones in the man last examples, none of those formats seem to work. Is there another way of doing this?
The --time-format option only accepts the following options:
--time-format <format> show timestamps in the specified <format>:
notime|short|full|iso
You might have to parse the datetime yourself, for example from ISO format.
I have the yml file which I used the "traslate" function to do lookup.
What was done is to translate a string like "superhost.com" to "found".
My problem is that if I were to add in more entries there entries will not be reflected.
For example
I add a "ultrahost.com" entry into the yml file while logstash is still running. Incoming logs with "ultrahost.com" will not be translated to "found". This will only work after I have restarted the logstash script.
There is a refresh_interval parameter to the translate plugin that can be used to specify how often to re-read the file. The default is 300 seconds (5 minutes). You can lower that to be whatever interval you think will satisfy how often that the file will be updated.
Hi I am new to logstash and grok filtering, I have a sample log like this:
1/11/2017 12:00:17 AM :
Error thrown is:
No Error
Request sent is:
webMethod:GetOSSUpdatedOrderHeader|appCode:OSS|regionCode:EMEA|orderKeyList:|lastModifedDateTime:1/10/2017 11:59:13 PM|
I want to filter out the line separator which is a line full of ** (the last line)
Also when I want to be able to capture entire line including ":" in one field. For example in the above log, webMethod:GetOSSUpdatedOrderHeader has to be captured in one field in my grok pattern. Is there a way to achieve this?? TIA. Please refer the attached image for the sample log message
A few tips:
Photos of logs are not a good way to offer someone an example, copy and paste the log
The Grok Debugger is a great way of building your own grok patterns
This should work for the sample log line you pasted in:
%{NOTSPACE:webMethod}\|%{NOTSPACE:appCode}\|%{NOTSPACE:regionCode}\|%{NOTSPACE:orderKeyList}\|%{NOTSPACE:lastModifedDateTime}
However, what you requested, probably isn't quite what you want, as you just want the field content in the result, not the name of the field as well. This should give you more sensible results:
webMethod:%{NOTSPACE:webMethod}\|appCode:%{NOTSPACE:appCode}\|regionCode:%{NOTSPACE:regionCode}\|orderKeyList:(?:%{NOTSPACE:orderKeyList}|)\|lastModifedDateTime:%{NOTSPACE:lastModifedDateTime}
You would then want to process the lastModifedDateTime field with the date filter to get the date stamp in a format logstash can save to.
I have a project I am working on and wanted to try to hook it up to the ELK stack beginning with logstash. Essentially I have python writing this to a file named stockLog:
{'price': 30.98, 'timestamp': '2015-08-03 09:51:54', 'symbol':'FORTY',
'ceiling': Decimal('31.21'), 'floor': Decimal('30.68')}
I have logstash installed and (ideally) ready to run. My logstash.conf file looks like this:
input {
file { path => "/home/test001/stockLog"
start_position => beginning }
}
output {
stdout {}
file {
path => "/home/test001/testlog"
}
}
My goal is to actually be able to see how logstash is going to read the python dictionary before I install Elasticsearch and start keeping data. Essentially even though logstash has a lot of formatting options I would like to just have my python script do the lifting and put it in a format that is easiest to work with downstream.
My problem is that no matter what I change in the logstash.conf file I can't get anything to print to my terminal showing what logstash is doing. I get no errors but when I execute this command:
test001#test001:~$ sudo /opt/logstash/bin/logstash -f /opt/logstash/logstash.conf
I get a message saying logstash has started correctly and the options of typing into my terminal but no stdout showing what it did if anything with the dictionary in my stockLog file.
So far I have tried "" around the file name and not. I have added the file output which you can see above to see if it actually writes anything to that file even though I don't see output on my terminal (it does not) and I have tried using the codec => rubydebug to see if logstash just needed an idea of the format I wanted to see. Nothing shows me any sign that logstash is doing anything.
Any help would be greatly appreciated and I there is more information needed by all means let me know.
Thanks!
In the end the answer turned out to be three steps.
Like mentioned above I needed to stop overwriting the file and just append to it instead.
I used the json filter to have the data easily broken down the way I wanted to see it. Once converted into json with json.dumps in python the logstash json filter handled the data easily.
I realized that it is pointless to try and see what logstash is going to do prior to putting it into elasticsearch because it is extremely easy to remove the information if it isn't shaped right (I am to indoctrinated by permanent indexes in splunk sorry guys).
