I am using Docker and ELK stack. And using date and grok filters to parse a custom logs.
During this experiment I found _grokparsefailure in the Kibana document.
I am trying to investigate more details, why Grok failed parsing the string.
I tried to use Logstash docker logs. But could not find any trace.
Is there any way to see the reasons behind grok parsing errors
Thanks, Raghu
Copy the message for the failed parsing and head to the Grok Debugger in the Dev Tools with your grok pattern. There you can debug what as going wrong.

Situation
I am using MongoDB 5.0 community server locally. I am creating with the shell at the moment.
Problem
When I set up validation, and test that validation, I get an error. But the error is collapsed in an [object].
I have searched everywhere online but I cannot figure out how to get "verbose" error logging?

This is what I see:
My goal is to see the error details inside the shell.
I need to be able to pass password to shell command but don't want it to be available in logs. I tried finding a solution and found something called an Obfuscated class in buildbot, but it seems i'm missing something it's not working and i couldn't find any examples.
Is their some other way or if this is the only way if someone could provide an example.
secrets are supported in Buildbot since 0.9.7. http://docs.buildbot.net/latest/manual/secretsmanagement.html
Using this api to access your secret will automatically make them redacted from the build logs.
I need to use Logstash to parse data from custom log files (generated from the our application). I have a tomcat server and mongodb. After going through the documentation online, I'm still unclear as to how to use the different input sources. There is a community based mongoDB database, but I'm unclear as to how use it.
How can I set up/ where should I start to begin using logstash parse logs from files?
I am installing the MapR and I stucked at starting warden after start zookeeper on a single node.
# service mapr-warden start
Error: warden can not be started. See /opt/mapr/logs/warden.log for details
On this file there is no detail. Does anybody have a hint? Thanks =)
If you aren't getting anything in warden.log, then it's likely that the warden JVM is never even being started by the mapr-warden init script.
In some MapR versions, the mapr-warden init script will log some details into /opt/mapr/logs/wardeninit.log. You can try checking there.
However, I will also caution that currently the logging done by the init script is sparse and not necessarily user friendly to read. If you can't discern the cause from the contents of the wardeninit.log you can post them here and maybe I can help.
Another thing you can do is edit /etc/init.d/mapr-warden and add "set -x" towards the top of the file, right before the "BASEMAPR=" line, then try starting warden again and you'll get a bunch of shell debugging output on your screen. If you copy and paste that output here that should be enough to tell the root cause of the problem.
One more thing to mention, you may be better off using the http://answers.mapr.com forum as that is MapR specific and I think there may be more users there that could help.
Was configure.sh (/opt/mapr/server/configure.sh -C nodeA -Z nodeA)run on the node? Did zookeeper come up successfully?
service mapr-zookeeper status
Even when using MapR in a single node configure.sh is still required. In fact, without configure.sh warden, zookeeper, cldb and other MapR components will lack their configuration and in many cases will fail to start.
You must run configure.sh after installing the software packages (deb or rpm).
How can I get log information from PostgreSQl server?
I found ability to watch it in pgAdmin Tolls->ServerStatus. Is there a SQL way, or API, or consol way, to show content of log file(s)?
Thanks.
I am command line addict, so I prefer “console” way.
Where you find logs and what will be inside those depends on how you've configured your PostgreSQL cluster. This the first thing I change after creating a new cluster, so that I get all the information I need and in the expected location.
Please, review your $PGDATA/postgresql.conf file for your current settings and adjust them in the appropriate way.
The adminpack extension is the one providing the useful info behind pgAdmin3's server status functionality.
