Hermes is a log and data file archival system provided as part of a Triton deployment. Hermes archives log (or other data) files from compute nodes and Triton internal service zones; for example, the usage telemetry files from the hagfish-watcher agent, or audit logs from CloudAPI.
Hermes transfers the nominated set of data or log files to the storage provided by a Joyent Manta instance, removing them from local disk only after the upload is complete and a configurable retention period has passed. Users without their own Manta deployment may use the public Manta instance available through the Joyent Public Cloud.
The server process expects to run in the "sdc" zone within a Triton
deployment. That zone must be able to access the Internet, or the network on
which the target Manta instance is available. Compute nodes access the target
Manta through a proxy running in the "sdc" zone, and thus do not themselves
require direct access.
