Description of problem:
Convolo DataGuard has a "cluster monitor" which is the same as your "cluster
status" except it automatically refreshes every 8 seconds. Can we have this with
a future release of Cluster Manager please..??
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Not Applicable
Actual Results: With "cluster status" you have to manual refresh the view
Expected Results: "cluster monitor" could refresh the view automatically at an
adjustable time interval.
The GUI is a nice idea but not always practical. For example you could be using
telnet to make remote configuration changes so you would prefer to use the
command line inteface to get the status of the cluster.
Nice to see the changes in status especially during demos.
The GUI tends to be rather java heavy.
"cluster status" calls an external program called "clustat".
Perhaps what you're looking for is "clustat -i <interval>"?
There are a couple of reasons "cluster monitor" isn't present in cluadmin, the
most important is the cluadmin session lock - there can be only one copy of
cluadmin running on the cluster at a time to ensure the integrity of the cluster
configuration. "clustat" doesn't use the session lock (because it doesn't have
the capability of modifying cluster information!).
"clustat -i <interval>" provides the exact function i was looking for - thanks.
