- /sprite/admin/migInfo - file containing the migration status
- of all Sprite hosts
-
- DDEESSCCRRIIPPTTIIOONN
- The migration status of all Sprite hosts is stored in ASCII
- format in a shared file, //sspprriittee//aaddmmiinn//mmiiggIInnffoo. Each host
- runs a daemon that is responsible for updating the informa-
- tion for its host. Each record is fixed length, to permit
- the daemons to update individual records without first pars-
- ing the entire file.
-
- Each record contains the following information, separated by
- white space:
-
- hostID numeric identifier of host.
-
- utilizations 3 weighted CPU utilizations, as percentages,
- separated by slashes.
-
- ready queues 3 weighted queue lengths, as floating-point,
- separated by slashes.
-
- boottime time at which host last rebooted (seconds
- since 1/1/70).
-
- timestamp time when record last updated, (seconds since
- 1/1/70).
-
- noInput number of seconds since keyboard or mouse
- input.
-
- allowMigration
- whether process migration to this host is
- allowed .
-
- foreignProcs number of migrated processes running on this
- host.
-
- migVersion version number of migration running on this
- host.
-
- pad Reserved for future expansion.
-
- Although the information is stored in ASCII format, to make
- it sharable by machines with different byte orderings,
- internally the migration database is accessed via routines
- that convert between ASCII and an internal C structure.
- Refer to the documentation for the mmiigg library for informa-
- tion about this structure.
