Find out causes and possible solutions. ## TSVB visualizations not visible in Kibana TSVB visualizations are not visible in Kibana. #### Cause Because of the CVE‑2020‑7015 vulnerability in the Kibana OSS 7.7.0 version provided by Search Engine Service, use of TSVB visualizations is restricted. #### Solution If you must use TSVB visualizations, edit the kibana.yml file and restart Kibana: 1. Connect to the manager node as the sshuser account. - See [Connect to the manager node via SSH (VPC)](/docs/en/ses-ssh-vpc) or [Connect to the manager node via SSH (Classic)](/docs/en/ses-ssh-classic). 2. Open the kibana.yml file by using the commands below: ``` sudo vi /etc/kibana/kibana.yml ``` 3. Delete the `metrics.enabled: false` on the last line of the file. 4. Restart Kibana by using `sudo systemctl restart` commands. Caution If you modify kibana.yml, it may be difficult to mitigate CVE‑2020‑7015. For details about E‑2020‑7015, see CVE-2020-7015. ## Stack Monitoring not supported You installed Elasticsearch OSS 7.7.0, but the Stack Monitoring feature is not visible. #### Cause In Elasticsearch OSS 7.7.0, Stack Monitoring is part of X‑Pack, a paid add‑on, and is not provided in the open‑source build. However, OpenSearch provides equivalent functionality even in the open‑source version. ### Solution As explained in Cause, this feature is not available. ## X‑Pack features not supported in Elasticsearch Elasticsearch provided by Search Engine Service does not include X‑Pack modules. #### Cause Elasticsearch provided by Search Engine Service is the open‑source (OSS) build and does not include X‑Pack modules (security, monitoring, machine learning, and other advanced features). In addition, Elasticsearch‑OSS stopped receiving updates at 7.10 and transitioned to OpenSearch, an open‑source project with equivalent functionality. #### Solution As explained in Cause, Elasticsearch‑OSS is no longer provided; use OpenSearch.
