Control Center 1.8.0
This page describes the changes in Control Center since release 1.7.0.
Beginning with version 1.4.0, Docker images for Control Center are no longer available on Docker Hub. The images are included in self-installing archive files that are available for download from Zenoss. Likewise, the RPM packages that are required for installations and upgrades are no longer available from Zenoss repositories on the internet, and must be downloaded. However, the Docker images and RPM packages for previous releases are still available from Docker Hub and Zenoss repositories, respectively.
Beginning 1 December 2017, downloads for Zenoss Service Dynamics customers are available on delivery.zenoss.io.

This release includes the following internal security and reliability updates:
- The Elasticsearch internal service is updated to release 7.7.1.
- The Zookeeper internal service is updated to release 3.5.5.
servicedbinary is now built with Go 1.14.
- The Go client library for Docker is updated.
In addition, Docker CE is updated to release 19.03.
Finally, this release includes a new configuration variable, SERVICED_LOGSTASH_STDOUT.
This update removes the historical data of Control Center gauges from
serviced internal HBase database. Resource Manager users are not
affected because the data is copied to the Resource Manager database.
This update reserves the 1001:1001 user/group IDs for Elasticsearch. If they're already in use for another user/group, you may wish to change them to a new user/group ID before the update. Not changing them does not affect Control Center.
