Interface IRequiredHostCounters

All Superinterfaces:

ICounterHierarchy

All Known Subinterfaces:

IHostCounters

All Known Implementing Classes:

SarCpuUtilizationCollector, VMStatCollector

public interface IRequiredHostCounters
extends ICounterHierarchy

The set of core (required) counters that must be reported for all platforms. The items declared on this interface are relative path names for ICounterSets and ICounters. The root for the path is generally the fully qualified domain name of a host (as reported by InetAddress.getCanonicalHostName(), a federation, or a service.

Note: it is good practice to keep these three namespaces distinct so that you can aggregate counters readily without these different contexts.

TODO:

This should only be monitoring local disk since NAS will typically be shared across a cluster and hence of its space remaining will be of little use to the LBS.

It will probably require platform specific configuration to select only the appropriate devices (which would also address the above concern)., not collected under linux.

PhysicalDisk_BytesReadPerSec

static final String PhysicalDisk_BytesReadPerSec

Disk bytes read per second for the host (vmstat).

PhysicalDisk_BytesWrittenPerSec

static final String PhysicalDisk_BytesWrittenPerSec
