3 DIVAprotect Operations

The DIVAprotect module is an analytical and monitoring option integrated into the Oracle DIVArchive Suite, bringing long-term content protection, management, and security to Oracle DIVArchive systems. DIVAprotect includes reporting through the Journal using various metrics as described in the following sections. The following operational information is included in this chapter:

Collecting Operational Events

Operational events are the primary events collected by DIVAprotect. The following three tables identify event fields and the types of events associated with them. There are three tables only due to the amount of entries. Locate the desired field on the top row of the table, and then follow down the column to identify which events are valid for the selected field.

Footnote 1 The transcoder work directory is not a DIVArchive disk. No DISK READ or DISK WRITE events are created when accessing this directory.

Collecting DIVArchive Hardware Resource Statistics

DIVAprotect collects hardware information from the tape drives and direct-attached libraries sent by the Actors. Library information is unavailable if a library server is used instead of direct-attached libraries. The information, called DIVArchive Resource Statistics, is updated in real time in DIVAprotect. The information is populated in the Drive Alert and Library Alert logs, and updates the tape drive's firmware information in the DIVArchive database. These special events are not available for use in Metric Definitions.

The following table lists the data sent by the Actors for each Quick Response Event type:

Footnote 1 The Actor issues Clean Alerts when a drive indicates it needs cleaning. These alerts are typically trapped by the library, or the library server, and the cleaning process is handled by those components. For this reason, DIVArchive does not include a drive cleaning mechanism.

Footnote 2 The Actor issues a Tension Alert when a drive indicates it requires re-tensioning.

Footnote 3 The Alert Log List is a variable length list of tape drive or library alerts. Each alert includes a parameter, a severity, and a text message.

Footnote 4 The Drive List is a variable length list of drive information objects. Each information object includes the Serial Number, Drive Name, and Firmware Release level. The Firmware Release level is saved in the database.

Collecting Quick Response Data (QRD)

DIVAprotect maintains a set of statistics about the archive system resources called Quick Response Data (QRD). QRD is not based on events, it is calculated from information available in the DIVArchive database, and updated every hour through an automated database job.

The following is a list of the QRD available, listed by resource:

Actors, Transcoders, and Analyzers

The QRD collected for these resources is the First Utilization Date.

Arrays

The QRD collected for arrays is as follows:

  • Total used space - this is the exact sum of used space across all disks in the array, both online and offline.

  • Total online object used space

  • Total externalized (offline) object used space

Disks

The QRD collected for disks is as follows:

  • First Utilization Date

  • Last Access, Last Read, and Last Write dates

Groups

The QRD collected for groups is as follows:

  • Total used space - this is the exact sum of used space across all disks in the array, both online and offline.

  • Total online object used space

  • Total externalized (offline) object used space

Libraries

The QRD collected for libraries is as follows:

Note:

Currently, a tape is considered offline only when it is ejected. After a tape is ejected it is not considered as part of the library.

  • First Utilization Date

  • Total number of tapes

  • Total number of Nearline (online) tapes

  • Total number of offline tapes

  • Total number of blank tapes

  • Total number of non-writable (write protected) tapes

  • Total offline capacity

  • Total free space capacity (online and offline total)

  • Total number of objects archived to the tapes in the associated library

  • Total number of objects Nearline (online)

  • Total number of objects offline

Media

The QRD collected for media is as follows:

  • First utilization Date

  • Last Utilization Date

  • Used space - this is the sum of offline and online instance sizes.

Objects

The QRD collected for objects is the Last Read Date.

Object Instances

The QRD collected for object instances in the Last Verify Date.

System

The QRD collected for the system is the First Use Date.

Source/Destination

The QRD collected for Source/Destinations is the First utilization Date.

Tapes

The QRD collected for tapes is as follows:

  • First Insertion Date - this is the date it first appeared in the system.

  • First Utilization Date - this is the date it was first mounted.

Collecting Drive and Library Alert Logs Information

Drive and Library Alert Logs contain a history of the codes that have been generated by the hardware. The Actors read the codes during normal operation. The information is saved to the database whenever reported by the hardware.

The following table is an extract of the Sony SAIT-1 Tape Drive Specification. Refer to your manufacturer's manual for your particular hardware.

Collecting and Calculating Metrics

This section describes how metrics are collected and calculated.

Calculating Metrics Based on Operations Events

Metrics are calculated and updated every hour by an automated database job running in the background. Each metric's calculation is based on a selection of Event Types (for example, SD READ, SD WRITE) from which a common event parameter is extracted (for example, Transfer Size), and processed by a statistical operation (for example, Sum). The metric takes into account events collected over a particular interval that depend on the Metric Type:

  • Hourly

  • Daily

  • Monthly

  • Yearly

  • Lifetime

A Metric is calculated based on associated events that occurred within the previous hour. If none of the associated events occurred, the metric is not calculated nor updated. If some associated events occurred, the metric is calculated or updated. All of the Metric Types are based upon these hourly calculations.

For example, if an associated event occurs at 10:00 AM on February 1st, 2017 the following Metrics (if they are defined) will be calculated or updated:

  • 10:00 AM Hourly Metric

  • 2/1/2017 Daily Metric

  • February 2017 Monthly Metric

  • 2017 Yearly Metric

  • Lifetime Metric

The following is a list of collection types:

Sum Collection Type

This collection type calculates a metric by adding event parameter values.

Count Collection Type

This collection type calculates a metric by counting event parameter values.

Minimum Collection Type

This collection type calculates a metric using the minimum event parameter value.

Maximum Collection Type

This collection type calculates a metric using the maximum event parameter value.

Average Collection Type

This collection type calculates a metric by averaging the event parameter values.

Weight Base Average Collection Type

This collection type calculates a metric by dividing the sum of the event parameter values by a weight factor, in contrast to the standard average calculation being divided by the count of event parameter values. Metrics configured with this collection type must specify a weight factor, otherwise the following error is generated:

ORA-20200 Weight Factor to calculate Weight based average is not mentioned.

The following is a sample Weight Based Average calculation:

Calculation for Hourly Metrics

SIZE (SUM of Transfer Size) / TIME (SUM of Transfer Duration) = V (Velocity)

Calculation for Day, Month, Year and Lifetime Metrics

Calculating DIVArchive Built-in Metrics

DIVAprotect comes with built-in metrics that do not appear in the Configuration Utility, and cannot be edited. The built-in metrics are available in the Control GUI with the standard ones. Built-in metrics names all start with DIVAPROTECT. The following are several of the built-in metrics. In each example, the first command is for daily counts, and the second command is for lifetime counts.

How many times was DIVAprotect executed?

The following metrics count how many times DIVAprotect has been executed. They update each time DIVAprotect runs the hourly database job.

DIVAPROTECT_EXECUTION_COUNT_DAY
DIVAPROTECT_EXECUTION_COUNT
How many events did DIVAprotect process?

The following metrics count how many events DIVAprotect has processed while calculating metrics. They are updated each time DIVAprotect processes an event.

DIVAPROTECT_EVENTS_PROCESSED_DAY
DIVAPROTECT_EVENTS_PROCESSED
How many metrics did DIVAprotect process?

This defines how many metrics DIVAprotect has calculated or updated. These metric values are updated each time a metric is calculated or updated in the DIVArchive system.

DIVAPROTECT_METRIC_PROCESSED_DAY
DIVAPROTECT_METRIC_PROCESSED
What is the number of DIVAprotect internal errors?

The following metrics count the total number of DIVAprotect errors that have occurred while calculating or updating a metric. They are updated each time an error occurs.

DIVAPROTECT_INTERNAL_ERROR_DAY
DIVAPROTECT_INTERNAL_ERROR_DAY

Monitoring Use and Statistics in the DIVArchive GUI

You can view the DIVAprotect Journal and Metrics through the Control GUI. Click the appropriate icon under the Analytics tab to display either the Journal View or Metrics View.

System Events (Journal)

DIVAprotect metrics are continually gathered and written to a temporary table in the database. Once per hour the metrics are removed from the temporary table and committed to a permanent table.

The Journal View provides a set of filters to narrow down data retrieval, and a list view for the retrieved information. You can filter by Event Definition, Drive Serial Number, Begin Date/Time, End Date/Time, and enter search keywords into the appropriate fields.

You can search for a particular Barcode, Actor Name, Source/Destination, Object Category, Object Instance Number, Error Code (including warnings, errors, and so on) and Error Message. You click Refresh on the top right of the display to apply your filters and perform the search.

To disable a filter, you can enter the wildcard character (an asterisk) for a text field, select the ALL value in a menu list, or deselect the check box to disable date and time filtering.

You can recall a previously used set of filters using the Previous Queries list (located in the lower right corner of the Journal view). The menu list remembers the last 10 used filter sets.
