I am having an issue here where I have a complete parse here for NGINXACCESSAUTH which leaves me with empty result for %{GREEDYDATA:message} and this not rewriting message field to empty, leaving me with messy outcome of message field being the full rsyslog source message as well as all the tags parsed.

Any idea how to go about this apart from removing part of the pattern so there is something for GREEDYDATA to parse?
Use keep_empty_captures => true to retain the empty message

I'm have an Ubuntu 20.04 VM with Elasticsearch, Logstash and Kibana (all rel.7.7.0) What I'm trying to do is (among other things) to have Logstash to receive Syslog and Netflow traps from Cisco devices, transfer them to Elasticsearch and from there to Kibana for visualization.
I created a Logstash config file (cisco.conf) where input and output sections look like this:
input {
udp {
port => 5003
type => "syslog"
}
udp {
port => 2055
codec => netflow {
include_flowset_id => true
enable_metric => true
versions => [5, 9]
}
}
}
output {
stdout { codec => rubydebug }
if [type] == "syslog" {
elasticsearch {
hosts => ["localhost:9200"]
manage_template => false
index => "ciscosyslog-%{+YYYY.MM.dd}"
}
}
if [type] == "netflow" {
elasticsearch {
hosts => ["localhost:9200"]
manage_template => false
index => "cisconetflow-%{+YYYY.MM.dd}"
}
}
}
The problem is: the index ciscosyslog is created in Elasticsearch with no problem:
$ curl 'localhost:9200/_cat/indices?v'
health status index uuid pri rep docs.count docs.deleted store.size pri.store.size
yellow open ciscosyslog-2020.05.21 BRshOOnoQ5CsdVn3l0Z3kw 1 1 1438 0 338.4kb 338.4kb
green open .async-search dpd-HWYJSyW653u7BAhQVg 1 0 2 0 34.1kb 34.1kb
green open .kibana_1 xA5PIwKsTHCeOFyj9_NIQA 1 0 111 8 231.9kb 231.9kb
yellow open ciscosyslog-2020.05.22 kB4vJAooT3-fbIg0dKKt8w 1 1 566 0 159.2kb 159.2kb
However the index cisconetflow is not created as seen in the above table.
I made a debug on Logstash and I can see netflow messages arriving from Cisco devices:

"ipv4_src_addr" => "172.16.1.21",
"in_pkts" => 24,
"flow_seq_num" => 17176
}
But at this point I can't tell if Logstash is not delivering the information to ES or if ES is failing to create the index, Current facts are:
a) Netflow traffic is present at Logstash input
b) ES is creating only one of the two indexes received from Logstash.
Thanks.
You have conditionals in your output, using the type field, your first input is adding this field with its correct value, but your second input does not have the field, so it will never match your conditional.
Add the line type => "netflow" in your second input as you did with your first one.
I am parsing logs from many daemons of UTM solution.
Grok and kv config looks like:
grok {
match => [ "message", "%{SYSLOGPROG} %{NOTSPACE:syslog_hostname} %{DATA:syslog_program}(?:\[%{POSINT:syslog_pid}\])?: %{GREEDYDATA:syslog_message}" ]
}
kv {
id => "syslogkv"
source => "syslog_message"
trim_key => " "
trim_value => " "
value_split => "="
field_split => " "
}
Usually events looks like
<30>2019:04:23-20:13:38 hostname ulogd[5354]: id="2001" severity="info" sys="SecureNet" sub="packetfilter" name="Packet dropped" action="drop" fwrule="60002" initf="eth3.5" outitf="eth5" srcmac="c8:9c:1d:af:68:7f" dstmac="00:1a:8c:f0:f5:23" srcip="x.x.x.x" dstip="y.y.y.y" proto="17" length="56" tos="0x00" prec="0x00" ttl="63" srcport="5892" dstport="53"
and parsed without any problem
But when some daemons generates events looking like (WAF in example)
<139>2019:04:23-16:21:38 hostname httpd[1475]: [security2:error] [pid 1475:tid 3743300464] [client x.x.x.x] ModSecurity: Warning. Pattern match "([\\\\~\\\\!\\\\#\\\\#\\\\$\\\\%\\\\^\\\\&\\\\*\\\\(\\\\)\\\\-\\\\+\\\\=\\\\{\\\\}\\\\[\\\\]\\\\|\\\\:\\\\;\\"\\\\'\\\\\\xc2\\xb4\\\\\\xe2\\x80\\x99\\\\\\xe2\\x80\\x98\\\\`\\\\<\\\\>].*?){8,}"
my output breaks and logstash stops processing any logs.
How can i exclude kv parsing events by regexp or any pattern?
In simple words - do not use kv if first words in syslog_message begins with "[" or any other regexp.
Wrap your kv filter in a conditional on the field:
if [syslog_message] !~ /^\[/ {
kv { }
}
Receiving a parsing failure with my grok match. I can't seem to find anything that will match my log.
Here is my log:

Here is my grok match. It works fine in the grok debugger.
filter {
grok {
match => { 'message' => '%{DATE:date} %{TIME:time} %{IP:client} %{WORD:method} %{URIPATHPARAM:request} %{NUMBER:status} %{NUMBER:bytes} %{NUMBER:time_taken} %{QUOTEDSTRING:referrer} %{QUOTEDSTRING:user_agent} %{QUOTEDSTRING:cookie}' }
}
}
EDIT: I decided to do a screenshot of what my log file looks like as the spaces dont come over when copying and pasting. Those appear to be single spaces when I copy/paste.
Beside the space in that logline you posted, which I assume won't exist in your logs, your pattern is incorrect on the date parsing. Logstash DATE follows this pattern:
DATE_US %{MONTHNUM}[/-]%{MONTHDAY}[/-]%{YEAR}
DATE_EU %{MONTHDAY}[./-]%{MONTHNUM}[./-]%{YEAR}
DATE %{DATE_US}|%{DATE_EU}
Which doesn't match your YYYY-MM-dd format. I recommend using a pattern file and defining a custom date format
CUST_DATE %{YEAR}-%{MONTHNUM2}-%{MONTHDAY}
then your pattern can be
%{CUST_DATE:date} %{TIME:time} %{IP:client} %{WORD:method} %{URIPATHPARAM:request} %{NUMBER:status} %{NUMBER:bytes} %{NUMBER:time_taken} %{QUOTEDSTRING:referrer} %{QUOTEDSTRING:user_agent} %{QUOTEDSTRING:cookie}
EDIT:
You may be able to handle weird whitespace with a gsub, this won't remove whitespace, but will normalize spaces to all be 1 " "
mutate {
gsub => [
# replace all whitespace characters or multiple adjacent whitespace characters with one space
"message", "\s+", " "
]
}
I am using Logstash to read some log file.

}
As seen from the output, the first output message has a grok parsing error and the other 2 outcomes did not fully parse the message. How should I modify my grok statement so it can fully parse the message?
For the first message, the problem comes from the two ?? that do no appear in the pattern, thus creating the _grokparsefailure.
The second and third message are not fully parsed because the first two pattern do not match the messages and so the message are parsed by the last pattern.
For the second message, if you wish to parse it with the first pattern (<%{TIMESTAMP_ISO8601:Timestamp}> (%{WORD:Level} - )%{NOTSPACE:Job_Code} => %{GREEDYDATA:message}), your pattern is false:
() around %{WORD:Level} - that do not appear in the log.
There is a space missing between :Timestamp}> and %{WORD:Level}. In the log there is two and only one in the pattern. Note that you can use %{SPACE} to avoid this problem (since %{SPACE} will match any number of space)
The %{NOTSPACE:Job_Code} match a sequence of character without any space, but there is a space in Export_Sysem 6 (1), so the Job_Code will be Export_Sysem and the => in the pattern will prevent successful matching with the first pattern.
Correct pattern :
<%{TIMESTAMP_ISO8601:Timestamp}> %{WORD:Level} - %{DATA:Job_Code} => %{GREEDYDATA:message}
For the third message, I don't see which pattern should be used.
If you add more details, I'll update my answer.
