This is my config:
input{
beats {
port => 55556
}
}
filter {
if "iis" in [tags] {
grok {
match => { "message" => "%{TIMESTAMP_ISO8601:log_timestamp} %{WORD:S-SiteName} %{WORD:S-ComputerName} %{IPORHOST:S-IP} %{WORD:CS-Method} %{URIPATH:CS-URI-Stem} %{NOTSPACE:CS-URI-QUERY} %{NUMBER:S-Port}$ %{NUMBER:SC-Win32-Status} %{NUMBER:SC-Bytes} %{NUMBER:CS-Bytes} %{NUMBER:Time-Taken}"}
}
}
}
filter {
if "nx" in [tags] {
grok {
match => { "message" => "\[%{TIMESTAMP_ISO8601:log_timestamp}\] (?<LogLevel>\[\w+\s*\]) (?<thread>\[\s*\d*\]) (?<snName>\[\w*\]) (?<snId>\[\d*\s*\d*\]) %{GREEDYDATA:message}"}
}
}
}
output{
if "nx" in [tags] {
elasticsearch {
hosts => ["localhost:9200"]
index => "nx-%{+YYYY.ww}"
user => "user"
password => "pass"
}
}
if "iis" in [tags] {
elasticsearch {
hosts => ["localhost:9200"]
index => "iis-%{+YYYY.ww}"
user => "user"
password => "pass"
}
}
}
Here's a log sample:
[2018-02-18 15:19:04.668] [INFO ] [ 155] [AliveReportCommand] [875076019 53033] - ProcessRequest Ended: elapsed time=00:00:00.0967851, _parser.Device.IsSuccess=False
[2018-02-18 15:25:32.716] [DEBUG] [ 181] [] [] - Web Facade called: streamIDParam=-1
This log corresponds to the "nx" logs.
For some reason it just does not get ingested. I ran grok simulation using the grok above and that code and it worked out great. However, it's like the "nx" filter is completely ignored. Even if I eliminate the "IIS" filter, still no info would show up on Kibana. Also no errors whatsoever in Logstash. I have the same setup for both using Filebeat:
- type: log
enabled: true
paths: c:\logs\*\*.log
exclude_files: ['mybeat.*']
tags: ["nx"]
multiline.pattern: '^\['
multiline.negate: true
multiline.match: after
- type: log
enabled: true
paths: C:\inetpub\logs\LogFiles\*\*.log
tags: ["iis"]
I think you must use only one filter.In your code you used two filter keywords.
filter {
if "iis" in [tags] {
grok {
match => { "message" => "%{TIMESTAMP_ISO8601:log_timestamp} %{WORD:S-SiteName} %{WORD:S-ComputerName} %{IPORHOST:S-IP} %{WORD:CS-Method} %{URIPATH:CS-URI-Stem} %{NOTSPACE:CS-URI-QUERY} %{NUMBER:S-Port}$ %{NUMBER:SC-Win32-Status} %{NUMBER:SC-Bytes} %{NUMBER:CS-Bytes} %{NUMBER:Time-Taken}"}
}
}
if "nx" in [tags] {
grok {
match => { "message" => "\[%{TIMESTAMP_ISO8601:log_timestamp}\] (?<LogLevel>\[\w+\s*\]) (?<thread>\[\s*\d*\]) (?<snName>\[\w*\]) (?<snId>\[\d*\s*\d*\]) %{GREEDYDATA:message}"}
}
}
}
I feel so embarrassed...
The problem wasnt with the filter to begin with.
It was with the timestamp set on Kibana.
After selecting the right field it showed up immediately.

The data is sent to elastic search but only 3 records are getting created for each document_id in the same index.
Only 3 records are created and every new logs incoming are overwritten onto the same document_id and the old one is lost.
Can you guys please help me out?
The definition of document_id is to provide an unique document id for an event. In your case, as they are static (apacheaccess, apacheerror, sqlerror), there will be only 1 event per index ingested into elasticsearch, overide by the newest event.
As you have 3 distinct data type, what you seems to be looking for provide for each event type (ApacheAccessLogs, ApacheErrorLogs, MysqlErrorLogs) a different index, as following :
output {
if "ApacheAccessLogs" in [tags] {
elasticsearch {
hosts => ["elasticsearch:9200"]
index => "apache-access"
}
}
if "ApacheErrorLogs" in [tags] {
elasticsearch {
hosts => ["elasticsearch:9200"]
index => "apache-error"
}
}
if "MysqlErrorLogs" in [tags] {
elasticsearch {
hosts => ["elasticsearch:9200"]
index => "mysql-error"
}
}
stdout {
codec => rubydebug
}
}
There are not many cases where you need to set the id manually (eg. in case of reingest of data), as Logstash & Elasticsearch will manage that by themself.
But if that's the case, and you can't use a field to identify each event individually, you could use the logstash-filter-fingerprint, that is made for that.
I'm trying to add LEVEL field (so it shows up in Kibana). My logstash.conf

Output I'm getting. Still missing received_at and level:
In that part of the configuration:
add_field => {
"received_at" => "%{#timestamp}"
"received_from" => "%{host}"
"level" => "levell"
}
When using "level" => "levell", you just put the String levell in the field level. To put the value of the field named levell, you have to use %{levell}. So in you case, it would look like:
add_field => {
"received_at" => "%{#timestamp}"
"received_from" => "%{host}"
"level" => "%{levell}"
}
Also the grok#match, according to the documentation:
A hash that defines the mapping of where to look, and with which patterns.
So trying to match on the levell field won't work, since it look like it doesn't exist yet. And the grok pattern you're using to match the message field don't match the example you provided.
I have a log line like this:
09 Nov 2018 15:51:35 DEBUG api.MapAnythingProvider - Calling API For Client: XXX Number of ELEMENTS Requested YYY
I want to ignore all other log lines and only want those lines that have the words "Calling API For Client" in it. Further, I am only interested in the String XXX and Number YYY.
Thanks for the help.

I actually posted the question here, for some reason I can't edit and followup.
how to grep particulr field from logstash output
You can have the json filter store the expanded JSON object in a subfield. Use the mutate filter to move the "repo" field into the toplevel and delete the whole subfield. Partial example from the json filter and onwards:
json {
source => "json_payload"
target => "json"
remove_field => "json_payload"
}
mutate {
rename => ["[json][repo]", "repo"]
remove_field => "json"
}
I am trying to grep only few fields from this output from logstash 1.repositories#create 2.\"repo\":\"username/reponame\" . please share your ideas to grep particular info from this outpput and assign this to another variable
"message" => "<190>Nov 01 20:35:15 10-254-128-66 github_audit: {\"actor_ip\":\"192.168.1.1\",\"from\":\"repositories#create\",\"actor\":\"myuserid\",\"repo\":\"username/reponame\",\"action\":\"staff.repo_route\",\"created_at\":1516286634991,\"repo_id\":44743,\"actor_id\":1033,\"data\":{\"actor_location\":{\"location\":{\"lat\":null,\"lon\":null}}}}",
I am using this syslog.conf file to get the output.

I am not able to add my comments for your reply, thank you so much for your reply.
could you please share your ideas to get username: and repo: only from this output , i m trying assign the values from this particular output, thanks again

Use a grok filter to extract the JSON payload into a separate field, then use a json filter to extract the fields from the JSON object. The example below works but only extracts the JSON payload from messages prefixed with "github_audit: ". I'm also guessing that the field after the timestamp is a hostname that should overwrite whatever might currently be in the "host" field. Don't forget to add a date filter to parse the string in the "timestamp" field into "#timestamp".
filter {
grok {
match => [
"message",
"%{SYSLOG5424PRI}%{SYSLOGTIMESTAMP:timestamp} %{HOSTNAME:host} %{GREEDYDATA:message}"
]
overwrite => ["host", "message"]
}
if [message] =~ /^github_audit: / {
grok {
match => ["message", "^github_audit: %{GREEDYDATA:json_payload}"]
}
json {
source => "json_payload"
remove_field => "json_payload"
}
}
}
