Statistics Database

The Statistics Database object controls the use of the statistics database on the EMS, and provides status information for it. It is a child of the Element Management System object.


If you enable the statistics database using the Status at next restart - enabled field, you should back up the contents of this database as part of your EMS Server live data backups. For more details of backing up your EMS Server's data, see the MetaSwitch Class 4/5 Softswitch Ancillary Servers Guide. The statistics database can create a significant amount of extra data to back up. Over time, the statistics database will accumulate a significant amount of data. Although the current version maintains statistics for only a small number of objects, more objects will be added to the statistics database in future versions, which will also increase the amount of space. On average, a year's worth of data for 1000 objects requires approximately 0.5 gigabytes of space.


Parameter

Access

Description
Current status - enabled Read only Specifies whether statistics for EMS objects are collected in the statistics database. Not all objects can have statistics collected in the database. Values:
  • True
    Statistics are collected in the database, and can be examined using the Statistics Database window on supported objects.
  • False
    Statistics are not collected in the database.
To enable or disable statistics database collection, see the Status at next restart - enabled below.
Current status - blocked Read only / Change This field is visible only when Current status - enabled is True. Specifies whether the collection of statistics in the database is currently blocked or not. Statistics collection is blocked in error conditions, for example if the EMS Server is short of disk space or if the database has become corrupted. Values:
  • True
    The collection of statistics has been blocked. To resolve this, check whether this object is alarmed; if so, check the log message identified by the Alarm log correlator fields, and take any action suggested in the log message. When you have cleared any alarm conditions, set the value of this field to False. The EMS will then attempt to resume statistics collection.
    Contact your MetaSwitch support engineer if this does not resolve the problem, or if blocking occurs frequently.
  • False
    The collection of statistics has not been blocked. You cannot change the value of this field when it is set to False.
Status at next restart - enabled Change Specifies whether the collection of statistics in the database is enabled at the next restart of the EMS. Values:
  • True
    Statistics are collected in the database, and can be examined using the Statistics Database window on supported objects. This is the default value for an EM4000 Series or EM3300A EMS Server.
  • False
    Statistics are not collected in the database. This is the default value for an EM3110 or EM3220 EMS Server.
Alarm state Read only Specifies whether any alarms are currently raised for this object. Values:
  • Clear
    No alarms are currently raised.
  • Attention Required
    Attention Required - the object is not operating normally, and needs operator intervention.
  • Attend To Dependent
    Attention Required elsewhere - another object on which this object depends is not operating normally.
Alarm state changed timestamp Read only Time at which the Alarm state last changed.
Alarm log correlator - Attention Required Read only Identifier of the log message for the event that caused the last Attention Required alarm state for this object. This field is reset when the Attention Required alarm events field is reset to zero.
Attention Required alarm events Read only / Reset Number of times (since this field was reset) that this object's alarm state has gone to Attention Required.
Attention Required alarm events reset timestamp Read only Time at which the Alarm events field was last reset to zero.
Alarm log correlator - Attend To Dependent Read only Identifier of the log message for the event that caused the last Attend To Dependent alarm state for this object. This field is reset when the Attend To Dependent alarm events field is reset to zero.
Attend To Dependent alarm events Read only / Reset Number of times (since this field was reset) that this object's alarm state has gone to Attend To Dependent.
Attend To Dependent alarm events reset timestamp Read only Time at which the Alarm events field was last reset to zero.
