This issue typically occurs due to a combination of trust store discrepancies and infrastructure configuration bottlenecks:
- Trust Store Mismatch: VCF Operations maintains a trusted certificates store for integrated endpoints. When a vCenter certificate is replaced, the old certificate remains in the trusted store while the new SSL certificate (or its Root/Intermediate CA chain) may not be fully trusted yet. This can lead to hidden SSL handshake exceptions (such as PKIX path building failed) during the data collection cycle, even if a basic connection test seemingly passes.
- Remote Configuration Constraints: The environment may lack adequate remote site monitoring capabilities, such as a localized proxy, preventing localized data retrieval.
- Infrastructure Bottlenecks: Lingering snapshots on the vCenter server, pending reboots, or resource constraints (CPU/Memory crunch) on the vCenter server appliance can halt/delay data collection processes.
