Description

From Dispatching containers to cloud VMs

  • (counter) cumulative instance time and cost, partitioned by allocation state and node type
In principle, these metrics can be estimated based on the existing instances_total and instances_price metrics. However:
  • prometheus doesn't offer an integral function
  • updating a cumulative metric after every worker/pool update (i.e., in updateMetrics()) would provide decent accuracy even when prometheus sampling is infrequent/unreliable.
