## Monitoring Metrics for Storage Nodes

- snServiceStatus – The current status of the storage node agent running on the host. The storage node agent manages all the replication nodes running on the storage node (host). The textual representation along with the enumeration ID are shown below:

  - starting (1) – The storage node agent is booting up.

  - waitingForDeploy (2) – The storage node agent is waiting for the initial deploy-SN command to be run from the admin console.

  - running(3) – The storage node agent is running.

  - stopping(4) – The storage node agent is in the process of shutting down. It may be in the process of shutting down replication nodes that it manages.

  - stopped(5) – An intentional clean shutdown.

  - errorRestarting(6) – Although this state exists in the category, it is typically never seen for storage node agents.

  - errorNoRestart(7) – Although this state exists in the category, it is typically never seen for storage node agents.

  - unreachable(8) – The storage node agent is unreachable by the admin service.

- snHostName – The name of the host where the storage node agent has been deployed.

- snRegistryPort – The port being used by the storage node agent for registering RMI objects.

- snHAHostName – If the HA host name has been configured through the boot parameters then this is returned, otherwise the name of the host running the storage node agent is returned. This represents the network interface name that is utilized by the replication subsystem for internode communication.

- snHaPortRange – The range of ports that replication nodes use to communicate amongst themselves.

- snStoreName – The name of the KVStore that this storage node agent is servicing.

- snRootDirPath – The fully qualified path to the root of the directory structure where the NoSQL database installation files exist.

- snAdminHttpPort – This parameter is passed from the storage node agent to the admin. The admin then uses this port to list on for HTTP requests.

- snLogFileCount – A logging config parameter that represents the maximum number of log files that are retained by the SNA.

- snLogFileLimit – A logging config parameter that represents the maximum size of a single log file in bytes.

- snCapacity – The current capacity of the storage node. This parameter essentially describes the number of persistent storage devices on the storage node and is typically set at store initialization time, but can be modified by the administrator if the hardware configuration is changed after the store is initialized.

- snMountPoints – A list of one or more fully qualified paths to the data files that reside on this storage node.

- snMemory – The current memory configuration for this storage node in megabytes. This parameter is typically set at store initialization time, but can be modified by the administrator if the hardware configuration is changed after the store is initialized.

- snCPUs – The current number of CPUs configured for this storage node. This parameter is typically set at store initialization time, but can be modified by the administrator if the hardware configuration is changed after the store is initialized.
