Service Impact 5.5.1

This release improves overall performance, better handles commit conflicts, simplifies relationship building, and reduces the time needed to change production states. To support this release, many ZenPacks were updated, to improve performance in defining Service Impact relationships, and reduce inconsistencies by consolidating edge providers with the DynamicView ZenPack.


For version information, please see the compatibility matrix on the Release Notes page.

Known issues

  • 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-740) During a graph update, the zenimpactgraph script creates one worker process for each available CPU core. Each worker requires up to 2GB of main memory. Without it, the host where the update is running may become unstable.
  • (ZEN-31885) Occasionally, graph update fails with traceback ModelCatalogError: Exception performing search. The workaround is to re-run the update.
  • After installing one or more ZenPacks that have updated relationship providers, rebuild the graph. For more information, see Rebuilding the graph database.
  • (IMP-832) Currently, it is possible to save a custom state provider with no conditions. When a custom state provider without a clear mapping is part of a model, events sent to a dynamic service do not get cleared. The workaround is to always provide a clear mapping.
  • (IMP-836) After a metatype configuration change, related service events are not cleared. To work around the issue, remove and then re-add the dynamic service.
