I am new to ELK and grok pattern matching. I am trying to build grok pattern match for my access log event and I am getting grokparsefailure message.
Here is my event log:
111.22.333.44 2015-09-15 14:27:02 POST /test/service/testservice 200 359 0.016
Grok pattern (after soem reasrch I came up with this):
%{IP:client}%{DATESTAMP_EVENTLOG:logeventtime}%{WORD:method}%{URIPATHPARAM:request}%{NUMBER:HTTPStatus}%{NUMBER:bytes}%{NUMBER:duration}
I suspected the issue might be with date match above and I tried to remove the psace between the date and time and try pattern matching and that did not work either. I removed the date and time all together and tried for the remaning and that also was giving same error. I am at a loss to where the issue is. any inputs would be helpful. Thanks!
Start here: http://grokdebug.herokuapp.com/discover?#
%{HOST:client} %{TIMESTAMP_ISO8601:event_date_time} %{WORD:http_method} %{URIPATHPARAM} %{NUMBER:status} %{NUMBER:bytes} %{NUMBER:duration}

This is my sample log.

I get a grokparsefailure.
Can anyone please help.
As per my understanding you're getting this error because the pattern you have used does not match the logs you have provided.
Can you be more specific what fields you are trying to capture from this log ?
I have wrote a grok pattern for the logs you must follow similar way such that it matches the whole log. In case you get found unknown escape character error use \ twice instead of single \
%{MONTH:month}%{SPACE}%{MONTHDAY:date}%{SPACE}%{TIME:time}%{SPACE}%{GREEDYDATA:temp1}\]%{SPACE}class\=\"%{WORD:class}\"%{SPACE}category\=\"%{GREEDYDATA:category}\"%{SPACE}ctx\=\"%{WORD:ctx}\"%{SPACE}filterNumber\=\"%{NUMBER:filternumber}\"%{SPACE}src\=\"%{IPV4:src}\"%{SPACE}srcPort\=\"%{DATA:srcport}\"%{SPACE}dest\=\"%{IPV4:dest}\"%{SPACE}destPort\=\"%{NUMBER:destport}\"%{SPACE}gwAction\=\"%{WORD:gwaction}\"%{SPACE}gwMode\=\"%{WORD:gwmode}\"
I have written the whole grok command please check if this works. I have made an assumption that u would get all logs in this format.
Use this website to test ur grok pattern: https://grokconstructor.appspot.com/do/match#result

As stated in the header: how can I use the match call?
I tried
http://router.project-osrm.org/match/v1/driving/8.610048,46.99917;8.530232,47.051?overview=full&radiuses=49;49
I am not sure, whether the list of radiuses is given correctly.
I can't get it work. I also tried [49;49] or {49;49} The command works with route:
http://router.project-osrm.org/route/v1/driving/8.610048,46.99917;8.530232,47.051?overview=full
For backround see here
Edit: If you look at the example here, itr seems, the timestamps are not needed /match/v1/{profile}/{coordinates}?steps={true|false}&geometries={polyline|polyline6|geojson}&overview={simplified|full|false}&annotations={true|false}
From the docs:
Large jumps in the timestamps (> 60s) or improbable transitions lead to trace splits if a complete matching could not be found.
I think that's the problem with your request. The two given points are more than 60s appart and OSRM cannot match them successfully. The radiuses are specified correctly.
The following query works for me:
http://router.project-osrm.org/match/v1/driving/8.610048,46.99917;8.620048,46.99917?overview=full&radiuses=49;49
This returns:
{"tracepoints":[{"location":[8.610971,46.998963],"name":"Alte Kantonstrasse","hint":"GKUFgJEhBwAAAAAAHQAAAAAAAAC5AAAAAAAAAB0AAAAAAAAAuQAAAPsCAACbZIMAsyXNAgBhgwCCJs0CAAAPABki8hY=","matchings_index":0,"waypoint_index":0,"alternatives_count":0},{"location":[8.620295,46.999681],"name":"Schönenbuchstrasse","hint":"nIEFAJ7IFIA3AAAAZAAAAAAAAADYAAAANwAAAGQAAAAAAAAA2AAAAPsCAAAHiYMAgSjNAhCIgwCCJs0CAAAPABki8hY=","matchings_index":0,"waypoint_index":1,"alternatives_count":5}],"matchings":[{"distance":922.3,"duration":114.1,"weight":114.1,"weight_name":"routability","geometry":"onz}Gqyps#Wg#S_#aCaFMUYo#c#w#OKOCWmAWs#aBiDsAsCMYH[HY\\_#h#ObBW^w#BQAUKu#ASF[ZaABOFYpAyIf#mD","confidence":0.000982,"legs":[{"distance":922.3,"duration":114.1,"weight":114.1,"summary":"","steps":[]}]}],"code":"Ok"}
So the two given input points 8.610048,46.99917 and 8.620048,46.99917 are matched to 8.610971,46.998963 and 8.620295,46.999681.
So as far as I can see, if you want to implement something like that, you need to give OSRM more input points on its way which are less than 60s apart.

I am trying to get the price items for performance block storage that are generic (not specific to a certain datacenter). I can see that these have the locationGroupId set to blank or null, but I can't seem to get the objectFilter to work with that, the query returns nothing. If I omit the locationGroupId filter I get a result that contain both location-specific and non-location specific prices.
GET /rest/v3.1/SoftLayer_Product_Package/759/getItemPrices.json?objectMask=mask[locationGroupId,id,categories,item]&objectFilter={"itemPrices":{"categories":{"categoryCode":{"operation":"performance_storage_space"}},"item":{"keyName":{"operation":"$=GBs"}},"locationGroupId":{"operation":"is null"}}}
I am guessing there is something wrong with the object filter, any ideas?
If I filter on locationGroupId 509 it works:
/rest/v3.1/SoftLayer_Product_Package/759/getItemPrices.json?objectMask=mask[locationGroupId,id,categories,item]&objectFilter={"itemPrices":{"categories":{"categoryCode":{"operation":"performance_storage_space"}},"item":{"keyName":{"operation":"$=GBs"}},"locationGroupId":{"operation":509}}}
The reason it the first query didn't work while the second did was that I used the command "curl -sg" to do the request. While that eliminates the need to escape the {}[] characters - it also turns off escaping other characters correctly in the URL - like the space in "is null". Changing that to "is%20null" solves the issue.
I am posting this as the answer as I find it likely for others to encounter this problem.
I'm quite new to ELK and Grok-filtering, and I'm struggling with parsing this particular pattern in my grok filter.
I've used the grok debugger to try and solve this, but although I like the tool, I just get confused by the custom patterns.
Eventually, I hope to parse lots of log files sent by filebeat to logstash, then send the parsed logs to elasticsearch and display with kibana or some similar visualization tool.
The lines that I need to parse follow the following pattern:
1310 2017-01-01 16:48:54 [325:51] [326:49] [359:57] Some log info text
The first four digits is a log type identifier, and will be used for grouping. I've called the field "LogLineID".
The date is formatted YYYY-MM-DD HH:MM:SS, and is parsed ok. I called the field "LogDate".
But now the problem begins. Within the square brackets, I have counters, formatted as MM:SS if you like. I cannot for the life of me find a way to sort these out, but I need to compare these times, hence I want to store them as minutes and seconds, not just numbers.
The first is a counter "TimeSpent",
the second is a counter "TimeStarted" and
the third is a counter "TimeSinceDown".
Then, last, comes the info text, which I've managed to grok with simply applying %{GREEDYDATA:LogInfo}.
I notice that the amount of minutes could be far higher than the standard 60 minutes within an hour, so I may be barking up the wrong tree here trying to parse it with date patterns such as TIMESTAMP_ISO8601, but then, I don't really know how else to do this.
So, I came this far:
%{NUMBER:LogLineID} %{TIMESTAMP_ISO8601:LogDate}
and were as mentioned able to (by cutting away the square bracket parts) to parse the log info text with
%{GREEDYDATA:LogInfo}
to create a field LogInfo.
But that's were I'm stuck. Could someone please help me figure out the rest?
Massive thanks in advance.
PS! I also found %{NUMBER:duration}, but it could as far as I could tell only parse timestamps with dot, not colon..
grok regex expression can help you solve the problem.
but first I wanna make sure that do you mean [325:51] [326:49] [359:57] are the three component that you wanna to fetch? And it will returns the result like :
TimeSpent: 325:51
TimeStarted: 326:49
TimeSinceDown: 359:57
were i get the point , you can use my ways in on of the following suggestions:
define your own custom pattern files and add the pattern in your file.
just use the expression in filter part of logstash conf file
hope it will helps you
Ah, there was a space.. Actually, I was misleading myself and everybody in my question, as it was not actually that log line that was causing problems. I just took the first one, not realizing where the problem really were, but the one causing problems had a space within the brackets as such: [ 42:31]. There are also some parts where there are two spaces, so the way I managed to solve this was to include a %{SPACE} between the \[ and the %{NUMBER}:
%{NUMBER:LogLineID} %{TIMESTAMP_ISO8601:LogDate} \[%{SPACE}%{NUMBER:TimeSpentMinutes}\:%{NUMBER:TimeSpentSeconds}\] \[%{SPACE}%{NUMBER:TimeStartedMinutes}\:%{NUMBER:TimeStartedSeconds}\] \[%{SPACE}%{NUMBER:TimeSinceDownMinutes}\:%{NUMBER:TimeSinceDownSeconds}\] %{GREEDYDATA:LogText}
I still haven't solved the merging of minutes and seconds, but this I can also handle in a later stage.
Thanks to Lin Don for showing an interest in my problem, and sorry for not replying sooner.
Hope the solution will help others (or even myself) if their stuck on the same kind of problem.
Note to myself: Read the logs more carefully before grok'ing.. :)
I just start to use fiddler in my project for debug purpose, but haven't figure out how to handle following case with autoresponder :(
I need replace the timestamp in the request url then point to the my personal path, like
from http://www.test.com/static/20140828/js/test.js
to http://www.test.com/static/mycode/js/test.js,
while the timestamp "20140828" changing frequently so I hope can have a rule can match and handle this kind replacement automatically, without update the timestamp every time.
I tried the regex but not found the solution for this case. Any suggestions would be appreciated. Thanks.
You're right that you need to use a regular expression; you haven't said what expression you tried.
You'll probably want to use something like:
MatchText REGEX:^.*test\.com/static/\d+/(.*)$
ActionText http://www.test.com/static/mycode/$1
