Hi,

Is it possible to get the disk quota at an organization level? As far as I see, the quota definition api doesnt return the disk quota[upper limit] info?

I want to calculate the used disc quota/Total disk quota for an organization.

Hi,



Since the documentation for the quota definition is quite unclear at the moment, have more questions reg the same.

I want to display the resource consumption (memory,disk usage,etc) at the org and space level.

1. Sometimes the sum of space quota definition exceeds the org quota definition. Is this a valid use case or bug?
2. Currently at an org level, there is no API to display the disk quota limit/usage, but its only at the application level.How do we approach this?
3. Also at the space level, there is a possibility that a space not being associated with the space quota definition. So, how do we get the total resources available(like memory, services, routes) for this space?

Good morning,

yes it is possible.

If you observe PWS panel or Bluemix you can observe that information.

Every organization has binded a OrganizationQuota and this definition affects to every applicattion deployed in any spaces binded to that organization.

The REST methods used to get the definition is:

http://apidocs.cloudfoundry.org/213/organization_quota_definitions/retrieve_a_particular_organization_quota_definition.html

The method to read the memory used is:

http://apidocs.cloudfoundry.org/222/organizations/retrieving_organization_memory_usage.html

You have an example here:
https://github.com/prosociallearnEU/cf-nodejs-dashboard/blob/master/services/HomeService.js#L69-L79

Remember that the memory used is the active memory. You can many applications staged but stopped. When you sum memory to the counter is when you start a new application to set of applications running in a space.

Hi Juan Antonio,

Thanks for the reply.

The API that you have mentioned gives me the memory usage of the org and not the disk quota/usage of the org. I need to know this info. In addition to that, I have added couple of more questions in my latest reply.

1. Sometimes the sum of space quota definition exceeds the org quota definition. Is this a valid use case or bug?
2. Currently at an org level, there is no API to display the disk quota limit/usage, but its only at the application level.How do we approach this?
3. Also at the space level, there is a possibility that a space not being associated with the space quota definition. So, how do we get the total resources available(like memory, services, routes) for this space?

Hi,

You have the reason. Disk quota is a parameter defined to app level only.
http://apidocs.cloudfoundry.org/213/apps/creating_an_app.html

When you create a new App, you define a set of parameters and one of them is disk of quota but when you define a Org Quota, disk_quota is not defined at that level.
http://apidocs.cloudfoundry.org/213/organization_quota_definitions/creating_a_organization_quota_definition.html

I am not sure if someone from Pivotal could confirm this fact, but I think that CC API doesn't have that feature at org/space level.

Anyway, at the moment, using the API, it is possible to do the same task but not in a direct way:

IDEA:

spaces = getSpacesFromOrg(org_guid)
long org_disk_quota = 0;
for each(space in spaces) {
apps = getAppsFromSpace(space_guid)
for each(app in apps) {
app_stat = getAppSummary(app_guid) or getAppStats(app_guid)
http://apidocs.cloudfoundry.org/226/apps/get_app_summary.html
http://apidocs.cloudfoundry.org/226/apps/get_detailed_stats_for_a_started_app.html
org_used_disk = app_stat.getDiskQuota();
}
}
System.out.println("Disk quota for current org: " + org_used_disk);

Sorry, before I didn't reply some questions.

1. Didn't test it. In my tests, I defined a quota at org level but I will test it.
2. I answered with the pseudocode.
3. The space adquired the limits defined in the quota for the organization.
