Change behavior of admin serviceStatus #5051
Description
Is your feature request related to a problem? Please describe.
The admin serviceStatus command lists hostnames and per host process counts by default.
On a production system this output is excessive and causes the terminal window to scroll off the result set.
A user has to add the --noHosts flag which provides a minimal view. However that strips off the group details.
Describe the solution you'd like
By default, the serviceStatus command should list a summary view of the system.
Similar to the following:
Managers: count: 1
resource group: (default)
Monitors: count: 1
resource group: (default)
Garbage Collectors: count: 1
resource group: (default)
Tablet Servers: count: 5
resource groups:
default: 2
group1: 3
Scan Servers: count: 4
resource group: (default)
Compactors: count: 14
resource groups:
default: 10
group1: 4
