<div dir="ltr"><div>In such cases, you need to use the "Dynamic pollsters operations" to process the sample, and retrieve the key as "rgw.main.size". By default, this value ("rgw.main.size") is interpreted as a nested dictionary.

<br>
To get the the size, in GB, occupied by buckets I need to manipulate a JSON key which contains a dot in its name:<br>
<br>
````<br>
- name: "radosgw.containers.objects.size"<br>
sample_type: "gauge"<br>
unit: "B"<br>
value_attribute: "rgw.main.size" <------------------------------------"rgw.main" is a JSON key, with a dot in its name, which belongs to "bucket.usage" JSON container <br>
url_path: "<a href="http://FQDN/admin/bucket?stats=True" rel="noreferrer" target="_blank">http://FQDN/admin/bucket?stats=True</a>"<br>
module: "awsauth"<br>
authentication_object: "S3Auth"<br>
authentication_parameters: my_access_key,my_secret_key,FQDN<br>
user_id_attribute: "owner"<br>
project_id_attribute: "tenant"<br>
resource_id_attribute: "id"<br>
response_entries_key: "usage"<br>
````<br>
<br>
But with this dynamic pollster definition, I get the python error "KeyError: 'rgw' ".<br>
<br>
In this case, is there a specific syntax to define "value_attribute" or am I doing something the wrong way ?<br>
