YARN resource manager message losgstash - logstash

I am trying to generate pie chart based on the final status of the job from RM logs. Since "RESULT=" string is in the "message" of the log, we are not able to extract it.
After doing some research we came to know that we need to write a grok pattern to break this string and extract "RESULT=".
Here is the string that I want to break, I want to extract user and result from this.

Is it possible to change a job ID to something human-readable?

I'd like to send myself a text when a job is finished. I understand how to change the job name so that the .o and .e files have the appropriate name. But I'm not sure if there's a way to change the job ID from a string of numbers to a specified key so I know which job it is. I usually have a lot of different jobs going at once, so it's difficult to remember all the different job ID numbers. Is there a way in the .pbs script to change the job ID so that when I get the message I can see which job it is rather than just a string of numbers?
If you are using Torque and add the -N flag, then you can add a name to the job. It will still use the numeric portion of the job id as part of the output and error filenames, but this allows you to add something to help you distinguish among your jobs. For example:
$ echo ls | qsub -N whatevernameyouplease

Logstash grok pattern for [2017-08-19T12:47:43,822][INFO][logstash.agent] Successfully started Logstash API endpoint {:port=>9600}

Can anyone give the logstash grok pattern for below lines. I want to take only timestamp alone.
[2017-08-19T12:47:43,822][INFO][logstash.agent] Successfully started Logstash API endpoint {:port=>9600}
[2017-08-19T12:49:47,213][WARN][logstash.agent] stopping pipeline {:id=>"main"}
I'm not sure to understand what you want but here are two possible solutions:
[%{GREEDYDATA:date1}][%{LOGLEVEL:debugLevel}][%{USERNAME:agentName}] %{GREEDYDATA:message} [%{TIMESTAMP_ISO8601:date2}][%{LOGLEVEL:debugLevel2}][%{USERNAME:agentName2}] %{GREEDYDATA:message}
This grok pattern will extract all information that you have in your log, then you decide if you want to use date1 or date2 field
%{GREEDYDATA:trash}[%{TIMESTAMP_ISO8601:date}]%{GREEDYDATA:trash}
This one will only return the second date of your log
Hope it helped !
If you only need the timestamp, this should do:
\[%{TIMESTAMP_ISO8601:date}\]
Results for your two loglines on https://grokconstructor.appspot.com:
If you want to match the whole pattern something like this may fit your needs:
\[%{TIMESTAMP_ISO8601:date}\]\[%{LOGLEVEL:loglevel}\]\[%{GREEDYDATA:agent}\] %{GREEDYDATA:message}
Results:

logstash filter , unfiltered lines

I am new to Logstash filter and going through different blogs and links to understand in detail. I have few questions which are still unanswered.
. If my log file has different log pattern e.g.
2017-01-30 14:30:58 INFO ThreadName:33 - {"t":1485786658088,"h":"abcd1234", "l":"INFO", "cN":"org.logstash.demo", "mN":"getNextvalue", "m":"fetching next value"}
2017-01-30 14:30:58 INFO AnotherThread:33 -my log pattern is different
I have below filter which is successfully filtering line 1 of the log
grok
{
match => [ "message", "%{TIMESTAMP_ISO8601:LogDate} %{LOGLEVEL:loglevel} %{WORD:threadName}:%{NUMBER:ThreadID} - %{GREEDYDATA:Line}" ]
}
json
{
source => "Line"
}
what will happen with the lines which can not be filtered using filter pattern?
Is there any way to capture all the lines which were not filtered and send to elasticSearch ?
Is there any good reading material where I can read about Input, Filter, Output plugins with the examples ?
To answer your questions:
The lines which cannot be filtered using grok would end up in a
grok_parsefailure. Make sure you handle it by dropping the lines
which don't actually match the filter criteria.
As far as I know you can't capture them separately and push it to ES. Maybe for this, you can have multiple grok patterns so that you can filter it out and send it to different ES indices thereafter.
I've added the links in the comment above.
This SO could come in handy. Hope it helps!
As #darth_vader points out, you'll get a "grok_parsefailure" tag on each document that doesn't match your pattern(s) in a grok{} filter. However, how you handle this failure is up to you.
By default, all the events will fall through to your output{} section, which presumably would send them to elasticsearch. You could also have a conditional output{} section, which sent parsed logs to one output and unparsed logs to another (a file{} output, or a different index, or...).
As for examples, the official doc tends to include incomplete fragments (at best), so you're probably going to find better examples in random internet blogs.

GROK Pattern filtering

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.

Store Multiple Identical Results from Logstash

So, say I have an event coming into Logstash as a multiline object (there are many events that all basically match the pattern below):
Starting script at 2015-11-12 15:06 EST
Found result a at 127.0.0.1
Found result b at 127.0.0.1
Found result c at 0.0.0.0
Script ended at 2015-11-12 15:07 EST
How would I go about matching this in such a way as to store each of the "Found ..." lines separately?
My current config file is something like:
filter {
grok {
break_on_match => false
match => {
"message" => [
"Starting script at ${TIMESTAMP_ISO8601:run_time}",
"Found result %{GREEDYDATA:result} at ${IP:result_ip}"
]
}
}
}
As it stands, this only captures one of the "Found result..." lines. (That is, it matches them all, but only stores one of them - there's only one result variable output.) I'd like to individually capture them, and store them as an... well, anything, so long as they're all there.
Is there a way to capture multiple of the same pattern and store all of the resultant capture data distinctly, while keeping the whole multiline event together so that I can tie it to header data such as the script start time?
I think you can use the split filter to achieve what you want. It allows you to split one event into several parts. The indivdual parts are all copies of the original event as far as I remember. You have to play with the terminator parameter which controls when the message is split into parts.
