Hello, going through http://www.ovirt.org/wiki/CLI to see some syntax hints. I don't see a way to get parameter of an object. For example if I want to see the size of a vmpool, how can I do it
you have two options for this:
1. show vmpool vmpool_name 2. list vmpools --show-all
yes, but they returns all the properties of an object. I would prefer to have an option that gives only the value of the property/properties I'm interested in something like show vmpool vmpool_name --props=prop1[,prop2,...,propN]
eg show vmpool vmpool_name --props=size
that's doable, can you file RFE on this?!
And is it possible to store values as variables and use then them for further commands?
this one of the features i have in my list.
i also have pipe support in my list, when it will be available, you will be able to redirect shell output directly to grep.
Ok, fine to have them. So in ovirt-shell command, when you type "help" and you get
" In addition to the basic command form, the following functionality is available: ... * The output of any command can be piped to a shell command with the '|' character. " Actually it is not implemented yet, corect?
true.
Because I tried some options but it seems none of them worked...
BTW: getting results seems quite slow in my opinion. Does it depend on ovirt-shell itself or something I can tune in PotgreSQL RDBMS parameters perhaps?
the query cycle is: 0. shell -> sdk 1. sdk: http request to server 2. api: unmarshal from xml2java 3. api 4. engine 5. db 6. engine 7. api 8. api: marshall to xml 9. sdk - unmarshall xml2python 10. cli foramt 11. shell i did profiling and results where good, unless server was really busy, in your case i believe latency caused by client side filtering, i.e --kwargs, you should use it only on collections where oVirt search not available (no --query option), or it doesn't answer your needs. --kwargs is very useful feature, but not efficient as in order to perform filtering on collection, its should get all collection members first.
