I have a custom log format ,i am new to it so trying to figure out how it works . It is not getting parsed in logstash .Can someone help to identify the issue.
Logformat is as follows
{u'key_id': u'1sdfasdfvaa/sd456dfdffas/zasder==', u'type': u'AUDIO'}, {u'key_id': u'iu-dsfaz+ka/q1sdfQ==', u'type': u'HD'}], u'model': u'Level1', u'license_metadata': {u'license_type': u'STREAMING THE SET', u'request_type': u'NEW', u'content_id': u'AAAA='}, u'message_type': u'LICENSE', u'cert_serial_number': u'AAAASSSSEERRTTYUUIIOOOasa='}
I need to get it parsed in logstash and then store it in elasticsearch
The problem is the none of the existing grok pattern are taking care of it and i am unaware of regex custom config
Alain's comment may be useful to you, if that log is, in fact, coming in as JSON you may want to look at the JSON Filter to automajically parse a JSON message into an elastic friendly format or using the JSON Codec in your input.
If you want to stick with grok, a great resource for building custom grok patterns is Grok Constructor.
It seems like you're dumping a json hash from python 2.x to a logfile, and then trying to parse it from logstash.
First - Fix your json format and encoding:
Your file doesn't correclty generated json strings. My recommendation is to fix it on your application before trying to consume the data from Logstash, if not you'll have to make use of some tricks to do it from there:
# Disable accii default charset and encode to UTF-8
js_string = json.dumps(u"someCharactersHere", ensure_ascii=False).encode('utf8')
# validate that your new string is correct
print js_string
Second - Use the Logstash JSON filter
Grok is module intended to parse any kind of text using regular expressions. Every expression converts to a variable, and those variable can be converted to event fields. You could do it, but it will be much more complex and prune to errors.
Your input has a format already (json), so you can make use of Logstash JSON Filter. It will do all the heavy lifting for you by converting the json structure into fields:
filter {
json {
# this is your default input. you shouldn't need to touch it
source => "message"
# you can map the result into a variable. Simply uncomment the
# following:
# target => "doc"
# note: if you don't use the target option. the filter will try to
# map the json string into fields into the 'root' of your event
}
}
Hope it helps,

I'm trying to parse multiline logs from my applications in fluentd on kubernetes.
I currently have the following filter dropped-in my fluentd container:
<filter kubernetes.**>
#type parser
key_name log
emit_invalid_record_to_error false # do not fail on non-matching log messages
reserve_data true # keep the log key (needed for non-matching records)
<parse>
#type multiline
format_firstline /\d{4}-\d{1,2}-\d{1,2}/
format1 /^(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}\.\d{3})\s+(?<level>\S+)(?:\s+\[[^\]]*\])?\s+(?<pid>\d+)\s+---\s+\[\s*(?<thread>[^\]]+)\]\s+(?<class>\S+)\s+:\s+(?<message>.*)/
time_format %Y-%m-%d %H:%M:%S.%L
types pid:integer
</parse>
</filter>
This filter should parse spring boot style logs (which is not that important, as it is not working for my other filters as well).
Single line logs are parsed fine! All capture groups are detected and time format and pid type is also saved as an integer. But in case of a multi line log statement, the next line is just left as it is and saved as its own entry.
I got the idea for this parser from the fluentd documentation: https://docs.fluentd.org/parser/multiline
The documentation says currently in_tail plugin works with multiline but other input plugins do not work with it.
The container I'm using uses the in_tail plugin to get the logs. But I'm using the parser inside a filter. Not sure if this might be the problem? In the documentation the parser filter plugin (https://docs.fluentd.org/filter/parser) just links to the Parser Plugin Overview (https://docs.fluentd.org/parser) without mentioning anything about single parsers not working.
Would be great if someone could point me into the right direction!
Thanks in advance!
I came recently to exactly the same issue and still couldn't find obvious solution so I had to figure it out myself. It is exactly as it is in doc - this parser you mentioned works only as Parser section in Input plugin ('in_tail' only). It doesn't work in filter plugin unfortunately.
But for me this plugin helped:
https://github.com/fluent-plugins-nursery/fluent-plugin-concat
You just have to add one filter section above your main one where you do this concat, e.g. my example looks exactly like this (indicator of real new log is timestamp, if there is no timestamp it is always stacktrace of errors where the problem appears):
<filter XYZ.**>
#type concat
key log
multiline_start_regexp /\d{4}-\d{1,2}-\d{1,2}/
</filter>
<filter>
# here the original filter
</filter>
I'm trying to create a Cloud Logging Sink with Terraform, that contains a regex as part of the filter.
textPayload=~ '^The request'
There have been many errors around the format of the regex, and I can't see anything in the documentation or other SO questions on how to properly create the script. Sinks are also not a valid option for a script generated by Terraformer, so I can't export the filter created via the UI
When including the regex as a standard string, the following error is thrown.
Unparseable filter: regular expressions must begin and end with '"' at line 1, column 106, token ''^The',
And when included as a variable with and without slash escapes variable "search" { default = "/^The request/" }
there is the following:
Unparseable filter: unrecognized node at token 'MEMBER'
I'd be grateful for any tips, or links to documentation on how I would be able to include a regex as part of a logging filter.
The problem is not with your query, which is obviously a valid query to search google cloud logging. I think it is due to the fact that you are using another provider (Terraform) to deploy everything. Which will transform your string values and pass them to GCP as a JSON. We ran into a similar issue and it caused me some headaches as well. What we came up with was the following:
"severity>=ERROR AND NOT protoPayload.#type=\"type.googleapis.com/google.cloud.audit.AuditLog\" AND NOT (resource.type=\"cloud_scheduler_job\" AND jsonPayload.status=\"UNKNOWN\")"
Applying this logic to your query:
filter = "textPayload=~\"^The request\""
Another option is to exclude the quotes:
filter = "textPayload=~^The request"
I am using Jmeter as Load Test tool.
I passing one parameter through request and in response I am getting only one parameter in result. response. I want to save both request and response in csv file.
I am using Regular Expression Extractor to capture response and Bean Shell Postprocessor to save it in csv file. But not able to capture respective request param.
Example: Request : http://localhost:8080/myService?input=abcd123455
and Response : pqrst1245/84985==
While here input for request I am taking it from another csv file.
and I want to capture both input parameter and corresponding response and store it in csv file like input,response ie. abcd123455,pqrst1245/84985==
Try using this Beanshell... I didn't try it out, but it should work.
import org.apache.jmeter.services.FileServer;
if (sampleEvent.getResult() instanceof org.apache.jmeter.protocol.http.sampler.HTTPSampleResult) {
String request = (sampleEvent.getResult().getSamplerData());
String response = prev.getResponseDataAsString();
fos = new FileOutputStream("/home/user/output.csv", true);
ps = new PrintStream(fos);
StringBuilder sb = new StringBuilder();
sb.append(request).append(",").append(response).append("\n");
ps.println(sb.toString());
ps.close();
fos.close();
}
The easiest way would be using Sample Variables property. Given you have 2 variables i.e. ${request}and ${response} just add the next line to user.properties file:
sample_variables=request,response
and restart JMeter to pick the property up. Once your test will be finished you will see 2 additional columns in the .jtl results file holding ${request}and ${response} variable values.
Another way to temporarily set the property is passing it via -J command-line argument like
jmeter -Jsample_variables=request,response -n -t test.jmx -l result.jtl
See Apache JMeter Properties Customization Guide article for more information on working with JMeter properties
I would not recommend to use scripting as when it comes to high load you may experience problems with multiple threads concurrently writing into the same file and you will need to think about implementing some form of write lock
I am trying to build a custom receiver adaptor. Which will read from CSV file and push events to a stream.
As far a I understand, we have to follow any of the WSO2 standard format(TEXT, XML or JSON) to push data to a stream.
Problem is, CSV files doesn't match with any of the standard format stated above. We have to convert csv values to any of the supported format within the custom adapter.
As per my observation, WSO2 TEXT format doesn't support comma(,) within a string value. So, I have decided to convert CSV JSON.
My questions are below:
How to generate WSO2 TEXT events if values ave comma ?
(if point 1 is not possible) In my custom adapter MessageType, if I add either only TEXT or all 3 (TEXT, XML, JSON) it works fine. But if I add only JSON I get below error. My target is to add only JSON and convert all the CSV to JSON to avoid confusion.
[2016-09-19 15:38:02,406] ERROR {org.wso2.carbon.event.receiver.core.EventReceiverDeployer} - Error, Event Receiver not deployed and in inactive state, Text Mapping is not supported by event adapter type file
To read from CSV file and push events to a stream, you could use the file-tail adapter. Refer the sample 'Receiving Custom RegEx Text Events via File Tail'. This sample contains the regex patterns which you could use to map your CSV input.
In addition to this, as Charini has suggested in a comment, you could also check out the event simulator. However, the event simulator is not an event receiver - meaning, it will not receive events in realtime, rather it will "play" a previously defined set of events (in the CSV file, in this case) to simulate a flow of events. It will not continuously monitor the file for new events. If you want to monitor the file for new events, then consider using the file-tail adapter.
I have just made it. Not an elegant way. However it worked fine for me.
As I have mentioned, JSON format is the most flexible one to me. I am reading from file and converting each line/event to WSO2 JSON format.
Issue with this option was, I want to limit message format only to JSON from management console ("Message Format" menu while creating new receiver). If I add only JSON [supportInputMessageTypes.add(MessageType.JSON)] it shows error as I mentioned in question#2 above.
The solution is, instead of putting static variable from MessageType class, use corresponding string directly. So now, my method "getSupportedMessageFormats()" in EventAdapterFactory class is as below:
#Override
public List<String> getSupportedMessageFormats() {
List<String> supportInputMessageTypes = new ArrayList<String>();
// just converting the type to string value
// to avoid error "Text Mapping is not supported by event adapter type file"
String jsonType = MessageType.JSON;
supportInputMessageTypes.add(jsonType);
//supportInputMessageTypes.add(MessageType.JSON);
//supportInputMessageTypes.add(MessageType.XML);
//supportInputMessageTypes.add(MessageType.TEXT);
return supportInputMessageTypes;
}
My request to WSO2 team, please allow JSON format event adapter type file.
Thanks, Obaid
I am trying to test a webservice's performance, and having a few issues with using and passing variables. There are multiple sequential requests, which depend on some data coming from a previous response. All requests need to be encoded to base64 and placed in a SOAP envelope namespace before sending it to the endpoint. It returns and encoded response which needs to be decoded to see the xml values which need to be used for the next request. What I have done so far is:
1) Beanshell preprocessor added to first sample to encode the payload which is called from a file.
2) Regex to pull the encoded response bit from whole response.
3) Beanshell post processor to decode the response and write to a file (just in case). I have stored the decoded response in a variable 'Output' and I know this works since it writes the response to file correctly.
4) After this, I have added 4 regex extractors and tried various things such as apply to different parts, check different fields, check JMeter variable etc. However, it doesn't seem to work.
This is what my tree is looking like.
JMeter Tree
I am storing the decoded response to 'Output' variable like this and it works since it's writing to file properly:
import org.apache.commons.io.FileUtils;
import org.apache.commons.codec.binary.Base64;
String Createresponse= vars.get("Createregex");
vars.put("response",new String(Base64.decodeBase64(Createresponse.getBytes("UTF-8"))));
Output = vars.get("response");
f = new FileOutputStream("filepath/Createresponse.txt");
p = new PrintStream(f);
this.interpreter.setOut(p);
print(Output);
f.close();
And this is how I using Regex after that, I have tried different options:
Regex settings
Unfortunately though, the regex is not picking up these values from 'Output' variable. I basically need them saved so i can use ${docID} in the payload file for next request.
Any help on this is appreciated! Also happy to provide more detail if needed.
EDIT:
I had a follow up question. I am trying to run this with multiple users. I have a field ${searchuser} in my payload xml file called in the pre-processor here.
The CSV Data set above it looks like this:
However, it is not picking up the values from CSV and substituting in the payload file. Any help is appreciated!
You have 2 problems with your Regular Expression Extractor configuration:
Apply to: needs to be response
Field to check: needs to be Body, Body as a Document is being used for binary file formants like PDF or Word.
By the way, you can do Base64 decoding and encoding using __base64Decode() and __base64Encode() functions available via JMeter Plugins. The plugins in their turn can be installed in one click using Plugin Manager
