Processing
1. Enscribe files are used to store all data managed on the NonStop (i.e. Main DB, Daily DB, Misc
DB, and Alert Def DB).
2. The scheduled SA Host scans through the node and gathers all required file and disk information.
The software includes optimization techniques, which allows the user to run the SA Host data
collections as several concurrent sub processes each of which can be set to run in a specific CPU
and priority. Although there is an option to run the collection less frequently, it is recommended to
run the SA Host process daily which will provide the most meaningful trending data and ensure that
the watchdog alerts are current. For each days run, the NSA creates a sub volume named
‘SA<yymmdd>’ that is used to store the daily databases. Main databases which reside on the
Subvolume to which the host is installed are used to store particular details posted and/or updated
during each run. There is a retention setting that allows to user predefine (i.e. set) a value in days
on how much historical data NSA will retain. Components involved: SA Host (SAMGR, SAPROC)
3. The SA Client module supports the GUI interface. In the archive view, a user can see the
corresponding disk/sub volume and its statistics. These statistics are hyperlinked to corresponding
files. A user can also filter statistics based on a user account. The archive view also enables
trending of accumulated data. Components involved: SA Client (SASVR)
4. The admin modules enables user to specify the CPU(s) to be used by SA Host for a collection
and the corresponding priorities of the processes involved in the collection. A log admin enables
user to view the available collection dates in a matrix and the process/CPU busy measurements
during a specific collection. Lastly, an alert definition admin lets the user set alert definitions for disk
alerts, file alerts and file exclude alerts. Components involved: SA Admin, SA Alert Def, SA Log
(SASVR)
Presentation
1. The system provides a browser based (using Internet Explorer - IE) Graphical User Interface
(GUI) that allows instantaneous presentation of archive data and graphs displaying trends and
particular category views. The underlying process is the SASVR process.
2. The main screen displays the statistics of each disk under the archive view. The user can click
these statistics to see the file list which was gathered based on the selected date. Alerts generated
for disks are displayed as hyperlink icons beside the disks. User can click on this and see the
disk/file list generating the alert. User can also use the filter option to only see disks or sub volumes
to which a user account has files on.
3. An admin screen is available to users. This screen will allow the user to change the settings such
as store volume, CPU(s) to use, priorities, and retention days. The underlying process is the
SASVR process.
4. A log admin screen is available to users. This screen allows the user to look at data matrix to
which date a collection exists. It also displays the CPU/Process busy measurements for that
collection run.
5. An alert admin screen is available to users. This screen will allow the user to set alert definitions
for disk alerts, file alerts and file exclude alerts. Users can set threshold values in these screens.
Scope
1. Storage Analyzer operates as a Plug-in to WVP
2. Storage Analyzer is node specific (i.e. collect data only on the node where running).
