Statistics policy parameters
Tables in this section describe the parameters available to configure statistics collection, and the type of statistics that can be collected.
Note: Not all versions of SR Linux support all statistics. If you
configure a policy to subscribe to a statistics path on a node that does not support it,
the system will collect only the supported data and will ignore any unsupported
subscription path.
Note: Because support for subscription paths varies for different
versions of SR Linux, some care is required with statistics subscriptions when upgrading
or downgrading the version of SR Linux on a node. Following an upgrade or downgrade of
the SR Linux software on a node, if the node supports a subscription path in that
specific software version, that path will not be automatically shown in the gNMI
subscription. To add the subscription path and retrieve the associated data, you must
first detach and re-attach the node label.
| Parameter | Description |
|---|---|
| Name | The name that identifies this policy. |
| Region | The region containing the node or nodes from which the statistics will be collected. |
| Node Selection by label | A single label that you created previously. The label must use the
"Node-type" label key. Nodes with this label will participate in the
statistics collection. Note: Currently, only a
single label can be selected. |
| Collection interval | The frequency, in seconds, with which the node gathers statistics.
(This is not the frequency with which the Fabric Services System communicates with the node.) The value can be a minimum of 5 seconds and a maximum of 300 seconds. |
| Enable this policy | A toggle that controls whether this policy is active (enabled) or inactive (disabled). |
| Subscription paths | Identifies one, some, or all of the predefined types of statistics to
collect from the participating nodes. A single policy can include a maximum of 36 paths. Note: The system
supports only one subscription policy for each node to avoid
collecting duplicate statistics. If you need to configure multiple
subscriptions for any node, avoid duplicating the same subscription
path in multiple subscriptions. |
