Hey there,
Graylog doesn’t like me anymore :frowning:

1. Describe your incident:

Indicies won’t be created

2. Describe your environment:

3. What steps have you already taken to try and solve the problem?

Nothing, cause I really don’t know what to do now :frowning:

4. How can the community help?

Tell me whats going on and whats the issue is

Hello @Gamienator

If you could show your configurations from the following:

  • Graylog
  • Elasticsearch

Also could you show the full messages, leaving out personal information?

Sure thing :slight_smile:

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: 192.168.0.1
#
# Set a custom port for HTTP:
#
#http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.seed_hosts: ["host1", "host2"]
#
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
cluster.name: graylog
action.auto_create_index: false

Graylog Part 1:

############################
# GRAYLOG CONFIGURATION FILE
############################
#
# This is the Graylog configuration file. The file has to use ISO 8859-1/Latin-1 character encoding.
# Characters that cannot be directly represented in this encoding can be written using Unicode escapes
# as defined in https://docs.oracle.com/javase/specs/jls/se8/html/jls-3.html#jls-3.3, using the \u prefix.
# For example, \u002c.
#
# * Entries are generally expected to be a single line of the form, one of the following:
#
# propertyName=propertyValue
# propertyName:propertyValue
#
# * White space that appears between the property name and property value is ignored,
#   so the following are equivalent:
#
# name=Stephen
# name = Stephen
#
# * White space at the beginning of the line is also ignored.
#
# * Lines that start with the comment characters ! or # are ignored. Blank lines are also ignored.
#
# * The property value is generally terminated by the end of the line. White space following the
#   property value is not ignored, and is treated as part of the property value.
#
# * A property value can span several lines if each line is terminated by a backslash (‘\’) character.
#   For example:
#
# targetCities=\
#         Detroit,\
#         Chicago,\
#         Los Angeles
#
#   This is equivalent to targetCities=Detroit,Chicago,Los Angeles (white space at the beginning of lines is ignored).
#
# * The characters newline, carriage return, and tab can be inserted with characters \n, \r, and \t, respectively.
#
# * The backslash character must be escaped as a double backslash. For example:
#
# path=c:\\docs\\doc1
#

# If you are running more than one instances of Graylog server you have to select one of these
# instances as master. The master will perform some periodical tasks that non-masters won't perform.
is_master = true

# The auto-generated node ID will be stored in this file and read after restarts. It is a good idea
# to use an absolute file path here if you are starting Graylog server from init scripts or similar.
node_id_file = /etc/graylog/server/node-id

# You MUST set a secret to secure/pepper the stored user passwords here. Use at least 64 characters.
# Generate one by using for example: pwgen -N 1 -s 96
# ATTENTION: This value must be the same on all Graylog nodes in the cluster.
# Changing this value after installation will render all user sessions and encrypted values in the database invalid. (e.g. encrypted access tokens)
password_secret = ''

# The default root user is named 'admin'
root_username = huhu

# You MUST specify a hash password for the root user (which you only need to initially set up the
# system and in case you lose connectivity to your authentication backend)
# This password cannot be changed using the API or via the web interface. If you need to change it,
# modify it in this file.
# Create one by using for example: echo -n yourpassword | shasum -a 256
# and put the resulting hash value into the following line
root_password_sha2 = 

# The email address of the root user.
# Default is empty
root_email = ""

# The time zone setting of the root user. See http://www.joda.org/joda-time/timezones.html for a list of valid time zones.
# Default is UTC
root_timezone = CET

# Set the bin directory here (relative or absolute)
# This directory contains binaries that are used by the Graylog server.
# Default: bin

#### HTTP bind address
#
# The network interface used by the Graylog HTTP interface.
#
# This network interface must be accessible by all Graylog nodes in the cluster and by all clients
# using the Graylog web interface.
#
# If the port is omitted, Graylog will use port 9000 by default.
#
# Default: 127.0.0.1:9000
http_bind_address = 127.0.0.1:9000
#http_bind_address = [2001:db8::1]:9000

#### HTTP publish URI
#
# The HTTP URI of this Graylog node which is used to communicate with the other Graylog nodes in the cluster and by all
# clients using the Graylog web interface.
#
# The URI will be published in the cluster discovery APIs, so that other Graylog nodes will be able to find and connect to this Graylog node.
#
# This configuration setting has to be used if this Graylog node is available on another network interface than $http_bind_address,
# for example if the machine has multiple network interfaces or is behind a NAT gateway.
#
# If $http_bind_address contains a wildcard IPv4 address (0.0.0.0), the first non-loopback IPv4 address of this machine will be used.
# This configuration setting *must not* contain a wildcard address!
#
# Default: http://$http_bind_address/
#http_publish_uri = http://192.168.1.1:9000/

#### External Graylog URI
#
# The public URI of Graylog which will be used by the Graylog web interface to communicate with the Graylog REST API.
#
# The external Graylog URI usually has to be specified, if Graylog is running behind a reverse proxy or load-balancer
# and it will be used to generate URLs addressing entities in the Graylog REST API (see $http_bind_address).
#
# When using Graylog Collector, this URI will be used to receive heartbeat messages and must be accessible for all collectors.

# This allows browsers to make Cross-Origin requests from any origin.
# This is disabled for security reasons and typically only needed if running graylog
# with a separate server for frontend development.

Hello,

Thanks for the add info. I found some configuration made. Im not sure if this would be the cause, just need to know if they were configured
I was wonder if you could explain the following

Does this persona have a Administrator roll for the system/Graylog?

# The default root user is named 'admin'
root_username = huhu

Just checking, I assume you had these filled in, is this correct?

 root_password_sha2 =
 password_secret = ''

I realize this node is set for default, perhaps trying to uncomment this out for troubleshooting?

 #elasticsearch_hosts = http://127.0.0.1:9200

I have a couple questions to ask you.

Is it possible to show your elasticsearch/Graylog log files during that time when trying to create a Index?

What type of index are you creating, Is it possible to show how this was done?

Is this post referring to creating the default index set?

Heyho,

so, regards your questions:

# The default root user is named 'admin'
root_username = huhu
root_password_sha2 =
password_secret = ''

are changed values, you said I should remove every personal data :slight_smile:

Here are some logs:

I create a index Set with the rotation config of delete index after 365 days and no, it should be then a standalone index, so I can later search for that in the log search

The way you have your indexes set up you have created more shards than Elasticsearch is meant to handle by default - here is a related post on Elasticsearch forums

Hello

@tmacgbay I just caught that :smiley:

@Gamienator

As for your second Log post, That looks like the GC logs, I was referring to elasticsearch logs.
Should be in this directory…

/var/log/elasticsearch

What @tmacgbay stated is correct, you have to many shards.

Hey everyone,

wanted to shout out that I was still not able to check this, since I got sick :confused: I’ll read all the documents soon and hopefully understand how to fix that :slight_smile:

Only wanted to write that down :slight_smile:

Hey everyone,

so I read a lot but I really don’t unterstand why I got so many shards, and how to reduce them :confused:. I do really struggle how to interact with it :confused:

Does anybody can give me a hint where to start or got a documentation?

You can see a lot more detail than you need about Elasticsearch shards here. Godd to skim so you have an understanding of how Elasticsearch data is stored relative to shards.

Each index you have in GRAYLOG manages settings in Elasticsearch for shards. If you go into Graylog System/Indicies and open an index, you likely have four shards (default) that would look like this:

Pulling a little math together - Your Index Set (perhaps named banana) has a series of indexes (banana_30, banana_31, banana_32…) depending on what your retention is. If your retention is 10 indexes, each having 4 shards… that is 40 shards of banana right there.

When you look at all of your Index Sets (System/Indicies) it should list in gray how many indexes are being retained - add those up, multiply by 4 (if you have taken 4 as default across the board) and you will have total shards.

I believe you only need a shard and/or replica per node in a cluster so if you are running a single node environment you only need one shard - DOUBLE CHECK THAT!!!

You can edit an index set and modify the number of shards it uses, but it won’t change until the index rotates to the next instance - which you can force.

Be careful on production systems - I am giving you forum advice, not expert advice… :smiley:

Aaah okay, so that happened.

I really overscaled the ability of the system. I got 23 Indicies, and I thought, well its okay to have a daily retention and save them vor 365 days! Oh boy was I wrong. When I was writing this post I changed that und turned the holding time for 30 days.

Yes I’m only running one node. Anyone other here that would say that too I’m needing only 1 shard?

Did some more research and here is some more detail on managing number of shards. if you have more than one they are used in parallel which would offer some advantage perhaps in a single node… more in a cluster of course.
