JBoss Operations Network Metrics for Connectors
The metrics provided by the JBoss Operations Network (JON) plugin for Red Hat JBoss Data Grid are for REST and Hot Rod endpoints only. For the REST protocol, the data must be taken from the Web subsystem metrics. For details about each of these endpoints, see the Getting Started Guide.
| Metric Name | Display Name | Description |
|---|---|---|
| bytesRead | Bytes Read | Number of bytes read. |
| bytesWritten | Bytes Written | Number of bytes written. |
Note
Gathering of these statistics is disabled by default.

|---|---|
| Start Cache | Starts the cache. |
| Stop Cache | Stops the cache. |
| Clear Cache | Clears the cache contents. |
| Reset Statistics | Resets statistics gathered by the cache. |
| Reset Activation Statistics | Resets activation statistics gathered by the cache. |
| Reset Invalidation Statistics | Resets invalidations statistics gathered by the cache. |
| Reset Passivation Statistics | Resets passivation statistics gathered by the cache. |
| Reset Rpc Statistics | Resets replication statistics gathered by the cache. |
| Remove Cache | Removes the given cache from the cache-container. |

| Synchronize Data | Synchronizes data from the old cluster to this using the specified migrator. |
| Disconnect Source | Disconnects the target cluster from the source cluster according to the specified migrator. |
JBoss Operations Network Plugin Operations for the Cache Backups
The cache backups used for these operations are configured using cross-datacenter replication. In the JBoss Operations Network (JON) User Interface, each cache backup is the child of a cache. For more information about cross-datacenter replication, see Chapter 29, Set Up Cross-Datacenter Replication
| Operation Name | Description |
|---|---|
| status | Display the site status. |
| bring-site-online | Brings the site online. |
| take-site-offline | Takes the site offline. |
Cache (Transactions)
Red Hat JBoss Data Grid does not support using Transactions in Remote Client-Server mode. As a result, none of the endpoints can use transactions.
22.6.3. JBoss Operations Network Plugin Attributes
| Attribute Name | Type | Description |
|---|---|---|
| cluster | string | The name of the group communication cluster. |
| executor | string | The executor used for the transport. |
| lock-timeout | long | The timeout period for locks on the transport. The default value is 240000. |
