Deployment Best Practices
Use the following guidelines to understand when to deploy policies on the Mid-tier connector or on a single connector or subset of connectors:
- Use the Mid-tier connector any time the situations previously described occur: you want to correlate across data sources, or you want to perform actions on all data sources. For action processing, using the Mid-tier connector is a more efficient operation than deploying a policy to all connectors, because the processing occurs in one location.
- Do not use the Mid-tier connector in most cases if you are limiting the matching events to those from a subset of connectors (unless you require cross-domain correlation). By rule, always deploy policies at the lowest level possible, which can be for one specific connector or a subset of connectors.
- Do not deploy a policy on a subset of connectors and the Mid-tier connector, because this creates a duplicate action in most cases.
- Deploy a policy with a normalization action on one connector only. Normalization actions do not support deployment on multiple connectors or the Mid-tier connector.
- Deploy out of the box enrichments (CA Spectrum, CA NSM, and CA CMDB) on the Mid-tier connector only. Other connectors do not support these enrichments.
- If you want to perform a JDBC enrichment on CA Catalyst connectors, deploy it on the Mid-tier connector. CA Catalyst connectors do not support direct JDBC enrichment deployment.
