So, let's assume that I have a portion of a log line that looks something like this:
Dec 11 13:59:17 172.00.1.00 NPF_OLT_LAB05: clear service affecting Alarm for ONT "100002" at 2019/12/11 13:59:17.28: "ONT Dying Gasp"
And I have to create a filter that does something like this
filter {
if ([message]) =~ "NPF_OLT_LAB05"{
grok{
match => { "message" => "%{SYSLOGBASE} %{WORD:Alarm_Severity} %{DATA:Message} %{QS:ONT_ID} %{DATA:Time} %{QS:ONT_Message}" }
}
}
}
Is this possible?
check with below configuration,
filter {
if "NPF_OLT_LAB05" in [message] {
grok{
match => { "message" => "%{SYSLOGBASE} %{WORD:Alarm_Severity} %{DATA:Message} %{QS:ONT_ID} %{DATA:Time} %{QS:ONT_Message}" }
}
}
}
I think you just have to correct a little bit. Try this
filter {
if ([message]) =~ /NPF_OLT_LAB05/{

I have two mutate filters created one to get all the /var/log/messages to type > security and other mutate filter to get all the logs from one kind of hosts to type > host_type.
I am not able to see the /var/log/messages in the host_type index.
Here is the filters code I am using, please help me understand what's going on here. why am I not able to see /var/log/messages in my apihost index?
I have filebeat setup on the hosts to send logs to logstash.
filter {
if [source] =~ //var/log/(secure|syslog|auth.log|messages|kern.log)$/ {
mutate {
replace => { "type" => "security" }
}
}
}
filter-apihost.conf
filter {
if (([host.name] =~ /(?i)apihost-/) or ([host] =~ /(?i)apihost-/)) {
mutate {
replace => { "type" => "apihost" }
}
}
}
Actually I fixed the issue by adding clone filter to my logstash config.
Log Sample
[2020-01-09 04:45:56] VERBOSE[20735][C-0000ccf3] pbx.c: Executing [9081228577525#from-internal:9] Macro("PJSIP/3512-00010e39", "dialout-trunk,1,081228577525,,off") in new stack
I'm trying to parse some logs,
I have tested some logs I have made on and it returning the result I need. But when I combining it with my config and run it, the logs not parsed into the index.
here is my config:
input{
beats{
port=>5044
}
}
filter
{
if [type]=="asterisk_debug"
{
if [message] =~ /^\[/
{
grok
{
match =>
{
"message" => "\[%{TIMESTAMP_ISO8601:log_timestamp}\] +(?<log_level>(?i)(?:debug|notice|warning|error|verbose|dtmf|fax|security)(?-i))\[%{INT:thread_id}\](?:\[%{DATA:call_thread_id}\])? %{DATA:module_name}\: %{GREEDYDATA:log_message}"
}
add_field => [ "received_timestamp", "%{#timestamp}"]
add_field => [ "process_name", "asterisk"]
}
if ![log_message]
{
mutate
{
add_field => {"log_message" => ""}
}
}
if [log_message] =~ /^Executing/ and [module_name] == "pbx.c"
{
grok
{
match =>
{
"log_message" => "Executing +\[%{DATA:TARGET}#%{DATA:dialplan_context}:%{INT:dialplan_priority}\] +%{DATA:asterisk_app}\(\"%{DATA:protocol}/%{DATA:Ext}-%{DATA:Channel}\",+ \"%{DATA:procedure},%{INT:trunk},%{DATA:dest},,%{DATA:mode}\"\) %{GREEDYDATA:log_message}"
}
}
}
}
}
}
output{
elasticsearch{
hosts=>"127.0.0.1:9200"
index=>"new_asterisk"
}
}
when I check it into kibana index, the index just showing raw logs.
Questions:
why my conf not parsing logs even the grok I've made successfully tested (by me).

log not get into if condition
It seems like your grok-actions don't get applied at all because the data get indexed raw and no error-tags are thrown. Obviously your documents don't contain a field type with value asterisk_debug which is your condition to execute the grok-actions.
To verify this, you could implement a simple else-path that adds a field or tag indicating that the condition was not met like so:
filter{
if [type]=="asterisk_debug"{
# your grok's ...
}
else{
mutate{
add_tag => [ "no_asterisk_debug_type" ]
}
}
}
I have such message to be parsed by grok filters:
"#timestamp":"2019-12-16T08:57:33.804Z","#version":"1","message":"[Optional[admin]]
(0.0.0.0, 0.0.0.0|0.0.0.0) 9999 approve
2019-12-16T08:57:30.414732Z","logger_name":"com.company.asd.asd.web.rest.MyClass","thread_name":"XNIO-1
task-5","level":"INFO","level_value":20000,"app_name":"asd","instance_id":"asd-123","app_port":"8080","version":"0.0.1-SNAPSHOT"
I tried http://grokdebug.herokuapp.com/ to parse my logs and i wrote such regexp to do it:
"#timestamp":"%{TIMESTAMP_ISO8601:logTime}","#version":"%{INT:version}","message":"[\D*[%{WORD:login}]]
(%{IPV4:forwardedFor}\, %{IPV4:remoteAddr}\|%{IPV4:remoteAddr})
%{WORD:identificator} %{WORD:methodName}
%{TIMESTAMP_ISO8601:actionaDate}%{GREEDYDATA:all}
it seems working in this debugger, but when i try to add this line to my filter in .conf file everything it writes is _grokparsefailure and my message remains unchanged, my filter:
filter {
grok {
match => { "message" => ""#timestamp":"%{TIMESTAMP_ISO8601:logTime}","#version":"%{INT:version}","message":"\[\D*\[%{WORD:login}]\] \(%{IPV4:forwardedFor}\, %{IPV4:remoteAddr}\|%{IPV4:remoteAddr}\) %{WORD:identificator} %{WORD:methodName} %{TIMESTAMP_ISO8601:actionaDate}%{GREEDYDATA:all}" }
}
}
try the below grok,
filter {
grok {
match => { "message" => "\"#timestamp\":\"%{TIMESTAMP_ISO8601:logTime}\",\"#version\":\"%{INT:version}\",\"message\":\"\[\D*\[%{WORD:login}]\] \(%{IPV4:forwardedFor}\, %{IPV4:remoteAddr}\|%{IPV4:remoteAddr}\) %{WORD:identificator} %{WORD:methodName} %{TIMESTAMP_ISO8601:actionaDate}%{GREEDYDATA:all}" }
}
}
Could you please advise how to filter a specific words with Logstash 1.5? For example, it's necessary to filter the following words: Critical, Exit, Not connected.
As I remember, in previous versions of Logstash (i.e 1.4 and earlier) it has been possible with grep filter.
Currently my logstash.conf contains:
input {
file {
path => ["C:\ExportQ\export.log"]
type => "Exporter-log"
codec => plain {
charset => "CP1251"
}
start_position => "beginning"
sincedb_path => "C:\Progra~1\logstash\sincedb"
}
}
filter {
}
output {
stdout { codec => rubydebug }
zabbix {
zabbix_host => "VS-EXP"
zabbix_key => "log.exp"
zabbix_server_host => "192.168.1.71"
zabbix_value => "message"
}
}
}
Many thanks in advance!
Use a conditional and the drop filter to delete matching messages.
filter {
# Simple substring condition
if "boring" in [message] {
drop { }
}
# Regexp match
if [message] =~ /boring/ {
drop { }
}
}
I have the following configuration file. But when I run this, I get the timestamp changed in the terminal but the log is not shipped to ElasticSearch.
Here is the configuration file:
input {
stdin {
type => "stdin-type"
}
}
filter {
grok {
type => "stdin-type"
patterns_dir=>["./patterns"]
pattern => "%{PARSE_ERROR}"
add_tag=>"%{type1},%{type2},%{slave},ERR_SYSTEM"
}
mutate
{
type=>"stdin-type"
replace => ["#message", "%{message}" ]
replace =>["#timestamp","2013-05-09T05:19:16.876Z"]
}
}
output {
stdout { debug => true debug_format => "json"}
elasticsearch
{
}
}
On removing the replace line, the log gets shipped. Where am I going wrong?
Run logstash with the verbose flags, and then check your logstash log for any output. In verbose mode, the logstash process usually confirms if the message was sent off to ES or why it wasn't.
Your config looks clean...if the verbose flags don't give you any meaningful output, then you should check your ES setup.
Try the second 'replace' in a second mutate code block.
mutate
{
type=>"stdin-type"
replace => ["#message", "%{message}" ]
}
mutate
{
type=>"stdin-type"
replace =>["#timestamp","2013-05-09T05:19:16.876Z"]
}
