Rebranding to EclecticIQ Intelligence Center in documentation
Rebranding from EclecticIQ Platform to EclecticIQ Intelligence Center in documentation is in progress. You may still see instances of “EclecticIQ Platform” remaining — please bear with us while we update the documentation.
Fixes#
In distributed environments, feeds may appear to momentarily fail when run
Fixed an issue where, in certain cases, a feed job may appear to fail, but is actually running.
In distributed environments, outgoing feeds packing a large amount of data may fail
Fixed an issue where outgoing feeds may fail due to worker deadlock when attempting to pack a large amount of data in distributed environments.
Known issues#
(Beta) Modern editor can cause UI crash when linking to objects with non-ASCII characters in its title
You can link to entities or observables in your Reports using both the (Beta) Modern editor and the older editor. However, if the title of that entity or observable contains non-ASCII characters, the UI crashes.
Elasticsearch 7 encounters “Data too large” errors: See Known issue with Elasticsearch 7: “Data too large”.
Entity incorrectly warns it is outdated: When viewing an entity, the entity may warn that it is not the latest version when it actually is. This is related to an issue where with attachments that have been depulicated multiple times, causing issues in the final state of the entity.
When you configure the Intelligence Center databases during a Intelligence Center installation or upgrade, you must specify passwords for the databases.
Systemd splits log lines exceeding 2048 characters into 2 or more lines.
As a result, log lines exceeding 2048 characters become invalid JSON, causing Logstash to be unable to parse them correctly.
When more than 1000 entities are loaded on the graph, you cannot load related entities and observables by selecting Load entities, Load observables, or Load entities by observable from the context menu.
When creating groups in the graph, it is not possible to merge multiple groups into one.
If an ingestion process crashes while ingestion is still ongoing, data may not always sync to Elasticsearch.
Users can leverage rules to access groups that act as data sources, even if those users are not members of the groups they access through rules.
Running multiple outgoing feed tasks may cause the Intelligence Center to consume a large amount of memory over time, because certain outgoing feeds such as HTTP download must load the data into memory in order to make it available to feed consumers.
New knowledge pack permissions#
In 2.11, permissions to install and access knowledge packs have
changed from ... configuration-bundles to ... knowledge-packs.
This means that if you’ve previously assigned ... configuration-bundles
permissions to users or roles, you have to re-assign the corresponding
... knowledge-packs permissions to allow those users or roles to retain
access to knowledge pack features.
Users assigned permissions through the System Admin role are not affected.
The table below lists the changed permissions:

Known issue with Elasticsearch 7: “Data too large”#
Since release 2.9.0, the Intelligence Center comes bundled with
Elasticsearch (ES) 7.9.1. ES 7 adds a new
real memory circuit breaker
that causes ES nodes to respond with a
circuit_breaking_exception error when it detects that
memory use has reached 95% of the totally available JVM
heap.
Because of this change, you may encounter issues related to available memory where previously at the same workloads, ES would appear to run smoothly.
If your plaform is encountering issues related to
Elasticsearch responding with a
circuit_breaking_exception error, you can do the
following to mitigate:
Increase available memory for ES#
The circuit_breaking_exception error occurs only when ES
detects that you are about to go over a memory use threshold
that would cause it to fail.
Increase the amount of memory available to ES, or move it to its own host where it does not compete with the Intelligence Center for resources to keep your ES nodes running.
(Not recommended) Disable the “real memory circuit breaker”#
Warning
This may allow ES to reach an out of memory state and fail.
(Not recommended) To disable the “real memory circuit breaker”, set the
indices.breaker.total.use_real_memory
parameter in your ES
configuration to false.
This allows ES to use the ES 6 parent circuit breaker instead, but disables the safety guarantees that the real memory circuit breaker provides.

Upgrade#
The following diagram describes the upgrade path you should take depending on the Intelligence Center version you are upgrading from.
For example:
You can upgrade from version 2.9.1 of the Intelligence Center to 2.10.0 directly,
To upgrade from 2.4.0 to 2.10.0, you must first upgrade to 2.5.0, then upgrade from 2.5.0 to 2.10.0.
When upgrading from 2.8.x and earlier to 2.9.x and later:
You must run the pre-upgrade script to allow it to work with Elasticsearch 7.9.1.
You must run the pre-upgrade script on the Intelligence Center version you are upgrading from.
For example, when upgrading from 2.8.0 to 2.10.1, you must run the pre-upgrade script on the Intelligence Center while it is running version 2.8.0.
Upgrade diagram#
From 2.5.0, the upgrades paths have been tested using the EclecticIQ Intelligence Center install script compiled by Rundoc.
The script only supports:
Single machine installs.
Instances installed using the Intelligence Center install script.
and does not support Intelligence Center instances installed in distributed environments.
