Hi, #49 proposed some patterns for bacula software (backup software), however there are no test being provided for this systems. If you know how this logs looks like it would be nice to have test that can validate this patterns works as expected.
All contributions are welcome, even if just some log examples, then we can workout the test for sure.
Hello,
This particular request on my HAProxy server is being tagged with ["_grokparsefailure"]. I am pasting the log event below. I have tried using the grok debugger and it says - "No matches"
May 26 03:51:23 localhost haproxy[13489]: 199.16.156.124:17410 [26/May/2015:03:51:23.433] http-in web-cluster/web-4 0/0/0/13/13 200 14631 - - --NR 0/0/0/0/0 0/0 {} {} "GET /tivamoservice/mo/275-Josh-Herbert-Live-Performance-and-Q&A HTTP/1.1"
My gut feeling says that the '&' character as part of the URIPATHPARAM is the reason for the pattern to fail.
It would be great if you could take a look at this.
Thank you,
Raghu

I was using the following snippet to parse a customized size postgres logfile:
grok {
match => {
"message" => [
"%{DATESTAMP:timestamp_psql} %{TZ:tz} ...
which worked very well. As it turned out, sometimes postgres is using multiline, so my first shot was:
multiline {
pattern => "^%{DATESTAMP}.*"
what => previous
negate => true
}
which did not work. Looking at the JSON i found:
"timestamp_psql": "15-07-10 09:31:57.030 UTC",
so the leading 20 is discarded. I mean, for most logfiles this should be totally fine, but for me it was very confusing. I guess grok somehow ignores leading and trailing data for pattern matching.
Im now using
multiline {
pattern => "^20%{DATESTAMP}.*"
what => previous
negate => true
}
as multiline filter (it works). but still thats wierd.
The MONTHDAY as is used by, among others, the RFC 2822 date stamp, must not require a leading zero for day-of-month < 10.

Hi!
I was looking for mongodb 3 log patterns and I end up here just to notice that your mongo patterns are outdated for the version 3 of the database
And example:
You say:
MONGO_LOG %{SYSLOGTIMESTAMP:timestamp} [%{WORD:component}] %{GREEDYDATA:message}
But the new version turns out to be:
%{TIMESTAMP_ISO8601:timestamp} %{WORD:severity} %{WORD:component} [%{WORD:context}] %{GREEDYDATA:message}
See official documentation on the matter: http://docs.mongodb.org/manual/reference/log-messages/
I'm looking for the rest of the patterns but this one groks just fine in my tests
As soon as I found any other will post here if you are ok with it
Thanks

It would be necessary as for example most NetBIOS hostnames include an underscore.

test would be necessary for the patterns:
DISABLE_HOST_SVC_NOTIFICATIONS
ENABLE_HOST_SVC_NOTIFICATIONS
DISABLE_HOST_NOTIFICATIONS
ENABLE_HOST_NOTIFICATIONS

ENABLE_SVC_NOTIFICATIONS
also example log lines would be necessary to write this patterns test properly.
See elastic/logstash#2101. This is coming up at customer sites as well.
The postgres grok pattern (https://github.com/elastic/logstash/blob/v1.4.2/patterns/postgresql#L2) doesn't seem to be compatible with postgres 9.4. I'm not sure when the format changed.
Specifically, the pid at the end is no longer there. This is what I'm using:
%{DATESTAMP:timestamp} %{TZ} %{DATA:user_id} %{GREEDYDATA:connection_id} %{DATA:level}: %{GREEDYDATA:msg}
as of #12 there is a lack of test for the junos firewall test, however there are no test being provided for this systems. If you know how this logs looks like it would be nice to have test that can validate this patterns works as expected.

See #10 for more details, (closed because of very long inactivity) for more detailed error description you can see: elastic/logstash#1734
From the main issue:
I figured I'd report the logs we're seeing from the syslog input plugin that aren't being parsed properly. The vast majority are being parsed just fine, but there are three edge cases that aren't.
This one fails because "Server Administrator" has a space in it:
<30>2014-09-15T11:35:55.965491-05:00 hostname Server Administrator: Storage Service EventID: 2243 The Patrol Read has stopped.: Controller 0 (PERC H800 Adapter)
This one fails because there's no message:
<4>2014-09-14T23:21:38.214167-05:00 hostname kernel:
This one fails because "run-parts(/etc/cron.hourly)" has parentheses in it. I've discussed this one with whack in the IRC channel, and he said this should be fixed in the next release, but I figured it should be documented:
<77>2014-09-15T06:01:01.687109-05:00 hostname run-parts(/etc/cron.hourly)[25969]: starting 0anacron
Hi,
It would be nice if you released a new version of the gem : there are a lot of new patterns since 1.10.
Please!!
In my particular case migrating from Logstash 1.4 to 1.5 is hurting due to pattern abductions (maybe aliens doing again).
The AWS ELB format spec includes SSL cipher and SSL protocol fields that aren't parsed by the currently available ELB_ACCESS_LOG
regex.
Since the last releases of this project we added a way to add test to the patterns so we're able to check for regressions, integrity, etc.
We need test for this new patterns added in the grok patterns lib, this are from cisco devices. If you are not confortable wirting ruby test, don't worry contributing log lines is good! then we can sort out the test π
_happy testing_
From LOGSTASH-2041
elastic/logstash#1162 adds underscore to first part of CISCOTAG, which allows it to match some tags I encountered, eg. SW_MATM-4-MACFLAP_NOTIF
There are a number of patterns that match integers (or floats) via e.g. %{INT:foo}
that are emitting string values for values that cannot be anything but numeric. This is an annoyance since it forces users to define their own Elasticsearch index templates with explicit mappings to get the fields correctly mapped in Elasticsearch. Users shouldn't have to do that if all they want to do is parse and visualize an Apache log; index templates should be for experienced users.
Example with problematic tokens highlighted:
HAPROXYHTTP %{SYSLOGTIMESTAMP:syslog_timestamp} %{IPORHOST:syslog_server} %{SYSLOGPROG}: %{IP:client_ip}:%{INT:client_port} [%{HAPROXYDATE:accept_date}] %{NOTSPACE:frontend_name} %{NOTSPACE:backend_name}/%{NOTSPACE:server_name} %{INT:time_request}/%{INT:time_queue}/%{INT:time_backend_connect}/%{INT:time_backend_response}/%{NOTSPACE:time_duration} %{INT:http_status_code} %{NOTSPACE:bytes_read} %{DATA:captured_request_cookie} %{DATA:captured_response_cookie} %{NOTSPACE:termination_state} %{INT:actconn}/%{INT:feconn}/%{INT:beconn}/%{INT:srvconn}/%{NOTSPACE:retries} %{INT:srv_queue}/%{INT:backend_queue} ({%{HAPROXYCAPTUREDREQUESTHEADERS}})?( )?({%{HAPROXYCAPTUREDRESPONSEHEADERS}})?( )?"(|(%{WORD:http_verb} (%{URIPROTO:http_proto}://)?(?:%{USER:http_user}(?::[^@]*)?@)?(?:%{URIHOST:http_host})?(?:%{URIPATHPARAM:http_request})?( HTTP/%{NUMBER:http_version})?))?"
Hi,
logstash 1.5.3 on windows won't read custom patterns file

I've read this issue on Jira (https://logstash.jira.com/browse/LOGSTASH-491), but could not replicate the pattern, as the patterns are not present anywhere, such as IPTABLESCHAIN, SPORT...).
As shorewall is a vey popular open source firewall product, could it be possible to add a pattern to filter its logs?
Thanks!

Hi,
There is an issue with the built-in pattern for Cisco ASA firewalls. The line :
# ASA-6-302020, ASA-6-302021
CISCOFW302020_302021 %{CISCO_ACTION:action}(?: %{CISCO_DIRECTION:direction})? %{WORD:protocol} connection for faddr %{IP:dst_ip}/%{INT:icmp_seq_num}(?:\(%{DATA:fwuser}\))? gaddr %{IP:src_xlated_ip}/%{INT:icmp_code_xlated} laddr %{IP:src_ip}/%{INT:icmp_code}( \(%{DATA:user}\))?
should be replaced by :
# ASA-6-302020_302021 inbound
CISCOFW302020_302021_1 %{CISCO_ACTION:action}(?: (?<direction>inbound))? %{WORD:protocol} connection for faddr %{IP:src_ip}/%{INT:icmp_seq_num}(?:\(%{DATA:fwuser}\))? gaddr %{IP:dst_xlated_ip}/%{INT:icmp_code_xlated} laddr %{IP:dst_ip}/%{INT:icmp_code}( \(%{DATA:user}\))?
# ASA-6-302020_302021 outbound
CISCOFW302020_302021_2 %{CISCO_ACTION:action}(?: (?<direction>outbound))? %{WORD:protocol} connection for faddr %{IP:dst_ip}/%{INT:icmp_seq_num}(?:\(%{DATA:fwuser}\))? gaddr %{IP:src_xlated_ip}/%{INT:icmp_code_xlated} laddr %{IP:src_ip}/%{INT:icmp_code}( \(%{DATA:user}\))?
Indeed, the src_ip & dst_ip are different if the direction is inbound or outbound.
I was reading grok patterns and found your pattern to parse combined apache log
your pattern to parse combined apache log, namely the NCSA log format, does not accept spaces in the authuser
field:
USERNAME [a-zA-Z0-9._-]+
USER %{USERNAME}
[...]
COMMONAPACHELOG %{IPORHOST:clientip} %{USER:ident} %{USER:auth} \[%{HTTPDATE:timestamp}\] ...
I read every documentations I could find on the subject, even NCSA HTTPd source code, and could not find any reference of escaping, forbidding, or replacing spaces in the authuser
field.
Yet a lot of people do it wrong too (starting by me, I personally have the habit to split my NCSA log lines on space, or use awk
, cut
, etc on them).
I personally thought at first I was right (to split on spaces, use awk, etc...), so I even opened a ticket on Varnish bug tracker.
I think we should open a conversation here on this subject, in one hand we either have a lot of people doing the same thing wrong, on the other hand we'll have hard times finding a clean way to encode authuser without dropping information, and convincing Apache, Microsoft, and Varnish, nginx, etc... to change their log handling code to change this...
I have a logfile whose lines may include snippets along the line of a=/some/path, b=some/other/path
. As an ELK user interested in these logs I would like to parse them with LogStash.
The logstash configuration:
filter {
grok {
match => { "message" => "((a=(?<a>%{PATH})?|b=(?<b>%{PATH})?)(,\s)?)+" }
}
}
when given a=/some/path, b=/some/other/path
LogStash gives the output:
{
"message" => "a=/some/path, b=/some/other/path",
"@version" => "1",
"@timestamp" => "2015-02-23T01:57:56.933Z",
"type" => "stdin",
"host" => "gallifry",
"a" => "/some/path,"
}
I expect b to bind to some/other/path
:
{
"message" => "a=/some/path, b=/some/other/path",
"@version" => "1",
"@timestamp" => "2015-02-23T01:57:56.933Z",
"type" => "stdin",
"host" => "gallifry",
"a" => "/some/path"
"b" => "/some/other/path"
}
Relates to #53
Providing basic log lines to create this patterns would be also necessary.
testing the patterns should be done in this repository, so http://github.com/logstash-plugins/logstash-filter-grok is a development dependency
It would be nice to have apache error log formats as grok patterns.

Propose adjusting the "auth" field to allow email address construct in COMMONAPACHELOG semantic.
Hello everone,
given the following log line that I am examining via http://grokdebug.herokuapp.com/:
10.67.1.38 - - [14/Sep/2015:09:46:40 +0200] "GET /measures/search_filter HTTP/1.0" 304 - "http://sonarqube/" "Mozilla/5.0"
The expression %{IP}|%{HOSTNAME}
results in a field IP
with the value 10.67.1.38
as expected.
Now if I use the shortcut %{IPORHOST}
then the field IP
is empty and HOSTNAME
contains the correct value. Is this behaviour normal?
From LOGSTASH-1677
The pattern named NAGIOS_HOST_NOTIFICATION doesn't match NAGIOS_TYPE_HOST_NOTIFICATION to the nagios_type field.
It should be:
NAGIOS_HOST_NOTIFICATION %{NAGIOS_TYPE_HOST_NOTIFICATION:nagios_type}: %{DATA:nagios_notifyname};%{DATA:nagios_hostname};%{DATA:nagios_state};%{DATA:nagios_contact};%{GREEDYDATA:nagios_message}
...as per the rest of the patterns matching nagios_type
Indeed the NAGIOS_TYPE_HOST_NOTIFICATION is an anonymous capture in NAGIOS_HOST_NOTIFICATION pattern definition
NAGIOS_HOST_NOTIFICATION %{NAGIOS_TYPE_HOST_NOTIFICATION}: %{DATA:nagios_notifyname};%{DATA:nagios_hostname};%{DATA:nagios_state};%{DATA:nagios_contact};%{GREEDYDATA:nagios_message}
https://github.com/logstash-plugins/logstash-patterns-core/blob/master/patterns/nagios#L69
where all others pattern use a named capture
Logins usually have an @
, it would be nice to have this pattern in for grok.

After updating my logstash from the repositories from 1.5.4 to 1.5.5, it wouldn't start anymore talking about a pattern %{HOST} not being defined.
After tracking down the change and the help of someone on IRC, it turned out it had been removed.
Could you mark this as a breaking change for 1.5.5 release and check if any other pattern is affected (and mark them as breaking change too)?
Thanks.

If a Cisco ASA has a logging device-id set (for instance with logging device-id string asa.sfo
), the syslog message emitted does not match the grok pattern CISCO_TAGGED_SYSLOG
. An additional space should be allowed by the pattern between the device_id and the colon.
Here are example messages to demonstrate:
without device-id:
<164>Nov 19 2014 17:27:56: %ASA-4-733100: [ Scanning] drop rate-1 exceeded. ...
with device-id:
<164>Nov 19 2014 17:30:36 asa.sfo : %ASA-4-733100: [ Scanning] drop rate-1 exceeded. ...
The example with device-id is not matched by CISCO_TAGGED_SYSLOG
because of the space in
asa.sfo :
Test for HTTP should be improved, for example including situations where the auth has actually content, for example like an email, see #3 for more details.
Having example logs to craft the test would be also a good to have to write the tests.
In my logs and both nagios and icinga documentation the SCHEDULE_SERVICE_DOWNTIME
is actually SCHEDULE_SVC_DOWNTIME

The patterns

JAVACLASS (?:[a-zA-Z0-9-]+\.)+[A-Za-z0-9$]+
is wrong. Class qualifiers should be optional and identifiers should be [a-zA-Z$_][a-zA-Z$_0-9]*

Hello,
I hope this can be of help. I wrote custom patterns for 90 different message IDs for Cisco ASA 5525X used as a VPN concentrator. Messages with severity code 6 or lower are parsed for multiple fields of interest. Severity code 7 messages are primarily parsed for group, ip, and user only. A few IDs have no values of interest and are matched without parsing so as to eliminate tags for grok parse failure.
I named the patterns from the message ID portion of the "ciscotag" field. ie. ciscotag:ASA-7-713169 would match pattern ASA_713169. Some message IDs occur in multiple severity levels.
Patterns -> http://pastebin.com/7iW8HB7g
Logstash config -> http://pastebin.com/32xGAEuB
NOTE: ASA_713906_1, and ASA_713906_2 encompass 15 different possible formats! (In my config, the other messages are matched if [ciscotag] != "ASA-7-713906, and these are matched if [ciscotag == "ASA-7-713906β.)

Hi,
Recently I began to use the EMAILLOCALPART pattern but it doesn't match accounts that start with a number so many maillogs provided by some solutions are not indexed correctly

So I think is better that the pattern should be:
EMAILLOCALPART [a-zA-Z0-9_.+-=:]+
