Service Impact 5.4.7 CA
This is a controlled-availability release. If you are interested in updating to this release, please contact your Zenoss representative.
This release includes a major new feature, selective synchronization.
In releases before 5.4.1, the Resource Manager Zope Object Database (ZODB) and the Service Impact graph database were tightly synchronized, and all of the relationships among Resource Manager devices and components in your environment (the "model") were copied to the Service Impact graph database. In larger environments, when Resource Manager model updates were underway, the synchronization process reduced performance in Resource Manager and caused Service Impact to make analyses with incomplete data.
In this release, you can refine the list of components that are copied from ZODB to Service Impact. This approach works well in environments where the critical services defined in Service Impact are a relatively small part of the Resource Manager model.
Additional highlights of this release:
- The SERVICES > Metatype Configuration page is the new interface for deciding which device components to exclude from Service Impact. The page includes counts of the overall number of entities in the Resource Manager model and the Service Impact model, updated regularly.
- The export/import/reconciliation process has been re-implemented to improve accuracy, reduce reconciliation conflicts, and provide progress information.
zenimpactgraph run --updateprocess has been re-implemented to scale out to the available host resources. The update time is reduced from days to hours.
- The zenimpactworker process is no longer necessary.
For version information, please see the compatibility matrix on the Release Notes page.
- In previous releases, adding a dynamic service was very quick, because the Service Impact database included all of the devices and components in the ZODB. In this release, Service Impact creates a background job to copy the devices and components it requires, which can take a few minutes to complete. Scripts that utilize the Service Impact JSON API must be updated to wait for the job to complete before proceeding.
- When you change the metatype configuration, the Service Impact database is updated to add or remove nodes. Depending on which items are changed, processing the changes can take 30-90 minutes in very large environments.
- (IMP-699) The upgrade to 5.4.x silently removes leading spaces from dynamic service names, which changes their sort order. To work around the issue, rename the services after the upgrade.

The state of a dynamic service is inconsistent when the production state of a member device is changed in Resource Manager
