IceStorm Metrics
You can monitor IceStorm using the Administrative Facility and the Metrics Facet. IceStorm provides two metrics class to monitor topic and subscriber related metrics. These classes are defined in
IceStorm/Metrics.ice
and are shown below.Slice
namespace IceMX { class TopicMetrics extends Metrics { long published = 0; long forwarded = 0; }; class SubscriberMetrics extends Metrics { int queued = 0; int outstanding = 0; long delivered = 0; }; };
IceStorm records metrics in the metrics map described below.
Metrics map name | Slice class | Description | Property prefix |
---|---|---|---|
Topic | IceMX::TopicMetrics | Topic metrics | IceMX.Metrics.view-name.Map.Topic |
Subscriber | IceMX::SubscriberMetrics | Subscriber metrics | IceMX.Metrics.view-name.Map.Subscriber |
To configure a metrics view to record IceStorm topic and subscriber you can use for example:
IceMX.Metrics.IceStormView.Map.Topic.GroupBy=id
IceMX.Metrics.IceStormView.Map.Subscriber.GroupBy=id
This will configure a view containing only the Topic
and Subscriber
maps. All the topics and subscribers from the IceStorm service will be monitored individually with separate metrics object.

Name | Description |
---|---|
id | The id is the topic name. |
