Thanks for sending this pointer! I read through the thread and have a few more
- Sounds like there are some terminology issues to reconcile as part of this?
- Should these shutdown states be represented in the visualization? If so, do you think
they should be represented as:
* A graduated scale of availability (shades of yellow/orange), to reflect the various
states of suspension or “out of sync” ness?
- or -
* A single “out of sync” (suspended?) state? If that were the case, perhaps “out of sync”
could be represented as an intermediate (yellow/orange) state between green and red.
Details about the state could be presented in a hover overlay, with a link to perform the
action needed ("restart" for example).
I think the latter is the better, as both *_REQUIRED states are effectively still RUNNING,
a configuration which is not the latest.
In RHQ we currently have UP/DOWN/UNKNOWN/ADMIN_DOWN (*) and are thinking of
extending this to
UP: Resource is available and working normally
DOWN: Resource is at fault and not working normally
MAINTENANCE: There is a scheduled maintenance period, availability may be UP or DOWN
MISSING: The resource was recorded in inventory, but does not exist in reality (e.g. was
deleted on file system)
ADMIN_DOWN/DISABLED: The resource exists, but was disabled by the admin (e.g. a network
interface on a 8 port card where only 1 cable is connected)
UNKNOWN: Resource state can not be determined
and also MIXED for groups of resources.
*) e.g. a network interface exists, but has no cable connected on purpose
