◆
A separate inservsample process is created for each InServ system being sampled. This
process in turn creates a separate CLI process that runs the sampler script which logs
into the array and collects the required data. The inservsample process then inserts the
data into the database. Along with the tables that contain the space and performance
data, the database also includes inventory tables that allow quicker creation of report
menus. The inservsample process also update the inventory tables.
◆
For MySQL and Oracle databases, the sampleloop service/daemon creates separate
process to maintain the database (since SQLite supports limited concurrency, these
functions are performed by the sampleloop process). These include:
◆
The trimdb process removes samples that are older than the sample retention period
specified in the sampling policies (see
7.2 Configuring Sampling Policies
◆
The dedupinv process removes duplicate entries from the inventory tables.
◆
The compactdb process periodically compacts and optimizes the database when
necessary.
■
Adaptive Optimization components. The sampleloop process also creates a regionmover
process for each InServ array for which Adaptive Optimization is configured (see
Selecting an InServ for Adaptive Optimization
on page 9.3). Each regionmover process
analyzes region level performance data for each Adaptive Optimization configuration and
generates region moves between tiers. The regionmover process creates a separate CLI
process that logs into the array and executes the mvrg program that executes the data
movement commands on the array.
■
Web server components. The 3PAR System Reporter Web server has customized scripts that
access the database to generate reports to standard browsers as clients, enabling users to
access the reports and configure System Reporter without installing any additional
software.
■
Excel client. The customized 3PAR System Reporter Excel client has built-in Web queries to
the Web server. Use of the Excel client is optional, but offers you additional customization
options. You must have Microsoft® Excel® in order to use the 3PAR System Reporter Excel
client.
