JUMP Session: Understanding and Configuring ElasticSearch for IBM Connections (on prem) [presentation, Q&A, audio + video attached]

Webcasts


Abstract

ElasticSearch Metrics is now available as an alternative software program for the Metrics feature within IBM Connections v6.0.
In addition, as of IC 6.0 CR3, type-ahead search & the recently visited views in Files & Communities make use of Elasticsearch.
In this session we will go through some of the common use cases to better understand these new capabilities in Connections. Then give administrators details of exactly how to setup and configure this in your environment.

Q&A

Q: If we install the non-Docker Elasticsearch environment, is it possible to switch later to the Docker-based?
A: Technically speaking, yes. You would need to install the new K8S or Docker based ES cluster then migrate (remote re-index) the data from old standalone ES cluster (after disable client certificate based authentication).
As we have not tested or documented how to do this yet however, we unfortunately would not be able to Support such a procedure. We have created a new Enhancement Request for this in the Connections Product Ideas Lab, however:
https://connections.ideas.aha.io/ideas/IDEACNCTNS-I-791
Please vote or comment on it! :-)
At the moment only migration from Cognos to ES is supported and documented in Knowledge Center. If you plan to use whole Pink stack, then our suggestion would be to move straight to Docker/Kubernetes.

Q: Is it possible to add own report?
A: It is not possible at the moment. Also the migration of custom Cognos reports is not supported.

Some further info from IBM Dev:
"No plans yet to support customers to use 3rd party tool to do analysis of Metrics data in ES so far.
The object ID is stored along with the Metrics event data in ES index. In Metrics UI application, we convert the ID into the name via Search API and show it in Metrics pages. So to use Kabana to access/analyze the data in ES, customers need to 1) understand the structure of Metrics index and the definition clearly  2) find a way to show the content/name of those ID.
For 1), we can plan some time to provide a documentation to explain Metrics index in ES."

I created another Enhancement Request for this:

Q: Can we use an existing ES infrastructure? We have one powering our internal search.
A: As long as the existing ES infrastructure adheres to the specs in the standalone ES documentation, then we will support it.
Those specs are as follows:
- The required Elasticsearch version is 5.5.1
- Elasticsearch requires Search Guard version 5.5.1
- See here for HW requirements:

Q: Does a updated guide for IcP (IBM Cloud Private) setup with Elasticsearch exist ? Is it still supported ?
A: For version before 6.0.0.6, only an ICp platform was supported.
For 6.0.0.6, our support statement is all around Kubernetes versions. So we state that we support Kubernetes v1.11. The platform you want to use is up to you, as long as it has Kubernetes v1.11. So if the customer wants to use ICP with 6.0.0.6 they can, but they would have to buy the version of ICP that hasKubernetes v1.11 (ICp v3.1)

Q: Can the type ahead serch data migrated from Solr to ES?
A: The answer is - there will be a migration path. The approach will be to do dual indexing to both Solr and ES for a period  
We have not published the details of that yet, but hopefully it will be soon.
For the moment, if you switch from Solr to ES, then users will lose their previous type-ahead search history because they would be building up a new index from scratch.
