OVNPM 1.5.2 - Performance Agent for NonStop Display Agent Guide

Using SystemAlert 131
• If your e-mail program uses the SMTP protocol, you must enter the e-mail addresses of the recipients
manually in the Recipients box. Separate each address with a semi-colon. The SMTP protocol does not
support interactive selection of e-mail addresses from an address book nor does it support address
aliases.
6. If you want to test the e-mail settings, click on the Send a Test Message button. A test message is sent to
each e-mail address in the list.
7. Click on the OK button.
9-11 Detecting Runaway Process Loops
The runaway loop detection feature of the SystemAlert module provides automatic supervision of your system. It
informs you of disturbing events on any process in the following areas:
• Excessive CPU Consumption
• Excessive Memory Consumption
Default values, which set a limit, exist for both CPU consumption and memory consumption.
Due to the continuous collection of data every 15 or 30 seconds, OVNPM can immediately detect and report if
CPU and memory consumption have exceeded their default values. This situation indicates a runaway process
loop. OVNPM automatically sends SystemAlert messages to the Display Agent. The Display Agent immediately
opens the Server Messages window with the appropriate message.
Reading Alert Messages
The first item in an alert message indicates if the process loop is an excessive CPU use (CpuLoop) or an excessive
memory use (MemLoop).
The table below explains the different elements in an alert message.
Item Description
Cpu CPU number where the process is running.
Cpu Busy Percentage of time the CPU spent executing the process.
CpuDist Percentage of time usage of the CPU where the process is running, in proportion to the CPU activity
during the last collect interval.
CreatTime Creation time of the process.
CurPages Number of memory pages that have been swapped by the process.
MsgRcvd Number of messages received by the process during the last collect interval.
MsgSent Number of messages sent by the process during the last collect interval.
OldPg For MemLoop, previous number of used memory pages followed by the number of times memory
use has continuously increased (prefixed by the symbol #).
OldPri For CpuLoop, previous priority of the process.
PageFlt Number of page-faults for the process during the last interval collection.
Pin Process Identification Number of the current process.
Pri Executing priority of the process.
Process Process name or unit name of the process.
Program Complete program file name of the process.
PrsTime Process time of the process.
RcvQLen Number of messages on the process reception queue.
Term Full name of the HomeTerm of the process.
