Overview ¶
Package osmap holds the vocabulary every OpenStack reader in Tally normalizes with: the divisors the reported quantities are converted by, the nova vm_state table, and which protocol a floating IP is an address of.
The collector (internal/providers/openstack) and the reconciliation adapter (internal/reporting/reconciliation/adapters) both read it. The two have to say the same thing: a sync that normalized a state or a quantity differently from the collector would report drift on every resource the collector had already booked correctly. Saying it once is what keeps them from drifting apart unnoticed.
It is a package of its own, and one that imports nothing but decimal arithmetic, because the adapter runs inside the Reporting API: importing the collector's own package would pull its AMQP consumer and its SQLite outbox into that binary.

Variables ¶
var ( MebibytesPerGibibyte = decimal.NewFromInt(1024) BytesPerGibibyte = decimal.NewFromInt(1 << 30) )
MebibytesPerGibibyte and BytesPerGibibyte are the divisors the reported quantities are converted with. Nova reports memory in MiB and glance reports image sizes in bytes, while the canonical size objects are in GiB.
Functions ¶
func IPVersion ¶
IPVersion reports which protocol a floating IP is an address of. An address that is absent or unreadable counts as IPv4, since that is what a deployment allocates unless it says otherwise, and it comes back together with the parse error, so a caller that wants to report the address it could not read can.
