Belka is your tool to explore your OpenStack based cloud and return valuable machine readable statistics.
Belka can be used as follows:
$ belka -h
usage: belka [--version] [-v] [--log-file LOG_FILE] [-q] [-h] [--debug]
belka
optional arguments:
--version show program's version number and exit
-v, --verbose Increase verbosity of output. Can be repeated.
--log-file LOG_FILE Specify a file to log output. Disabled by default.
-q, --quiet suppress output except warnings and errors
-h, --help show this help message and exit
--debug show tracebacks on errors
Commands:
compute Query compute nodes for statistics
help print detailed help for another command
The compute subcommand provides further options:
$ belka help compute
usage: belka compute [-h] [--noheader] [--noindividual] [--noaggregate]
[--syslog] [--identifier IDENTIFIER]
Query compute nodes for statistics
optional arguments:
-h, --help show this help message and exit
--noheader, -r Do not print header line
--noindividual, -i Do not print individual hypervisor stats
--noaggregate, -a Do not summarize hypervisor stats
--syslog, -s Send to syslog instead of stdout
--identifier IDENTIFIER, -d IDENTIFIER
identifier string to be included in output
Belka will query your Nova cluster to find the following stats per hypervisor:
- memory_mb
- current_workload
- vcpus
- running_vms
- vcpus_used
- memory_mb_used
- hypervisor_hostname
It can also summarize this information.
Here is an example run of belka:
$ belka compute

Storage requires a user that has the keystone "ResellerAdmin" role. You can add this to your "admin" user with the following command:
$ keystone user-role-add --user admin --role ResellerAdmin --tenant admin
