Detection server advanced settings are different on an upgrade VS a new installation.

Products

• Data Loss Prevention Network Monitor and Prevent for Email and Web

Issue/Introduction

In DLP 16.0 it was observed that upgrade servers have 2 advanced settings that a new installation does not and you would like to know if this is by design. 

The two settings are 

DiscoverCluster.ContentFetcherThreadPoolSize

DiscoverCluster.CrawlerThreadPoolSize

Environment

DLP 16.0 and DLP 16.0 RU1

Cause

When a new Network Discover Cluster is added as a new Monitor, these settings are added as they are necessary settings for this new kind of monitors.
When adding other types of non-cluster Monitors, these DiscoverCluster settings are not applicable so none are added for these types of monitors.

The current migration design can't distinguish what type of monitor new setting advanced attributes added in a new version are applicable so when it adds these new settings to existing monitors, it ends up adding these two new settings to all monitors regardless of monitor type.

Resolution

As these settings are not applicable to the other Monitors the setting is completely ignored.

No action is required, this is by design.
