I'm trying to clarify some vagueness between various .pdf articles and
this forum post. The admin guide ( vi3_35_25_admin_guide.pdf ) on
page 54 says:
When an object is removed from the inventory, its log and event history
remains until urged through the aging processes. Data is kept for a
specified window of time. As the time window shifts, older data is purged.
Similarly, the older VC v1.3 Users Manual (vc_users13.pdf)[2] on page 418 says:
When an object is removed from the VirtualCenter inventory, its log and event history
remains until purged through the normal processes.
This forum thread (http://communities.vmware.com/message/935150), however, indicates that the
'normal aging process' is, in fact, a manual, interactive maintenance procedure. Am I reading
understanding this correctly?
If there is no configurable or automated mechanism for deleting from these tables, what is the
"specified window of time" that the admin guide refers to? Is there a difference in the 'aging
process' between ESX 3.0.x, ESX 3.5, ESX 3i/e, and/or Virtual Center 2.x deployments? If there
is an automatic purging process, does anyone know how the SDK EventHistoryCollector and/or
TaskHistoryCollector objects are supposed to behave when faced with modifications to the
underlying persisted history?
Thanks for any clarification anyone can offer.
