OVNPM 1.5.2 - Performance Agent for NonStop Server Monitoring Guide

2-3-2 Instance Name Using the SPN

Instance name identifies an instance. The instance name length must be lower than 32 bytes. Instance name for

in domain DISKFILE, PROGRAM and FILESIZE can use the OSS pathname if only the pathname length is lower

than 32 bytes. If length is higher than 32 bytes the SPN must be used.

The USERCFG Syntax of an instance using an SPN is:

<domainName> [spnId]<pathname> [,trend=on|off]

Where:

domainName is one of FILESIZE, DISKFILE, and PROGRAM domains.

spnId is id of optional and already defined Symbolic Path Name.

pathname is the OSS pathname (always starting with sign ’/’).

NOTE:

Length of spnId + pathname that is instance name must be lower than 32 bytes. All pathname starts by

character “/”.

The instances declaration gives the instance type. For example:

Instance definition

Instance type

program /bin/sh ,trend=off OSS pathname of a sh program in directory /bin. Notice sign ‘/’ starting

instance name

program websvr/bin/httpd ,trend=off

SPN of program httpd program in the ‘websvr/bin’ directory

program $data02.ovpmexe.cm ,trend=off

Guardian name of CM program in sub volume ‘$data02.ovnpmexe’.

NOTE:

The drill-down and right-click feature in the OVNPM interfaces provides, at any time, the full OSS

pathname from any SPN.

2-3-3 SPN Restrictions

OVNPM does not support expand OSS pathname that is pathname starting by “/E/”

OVNPM does not support guardian OSS pathname that is pathname starting “/G/”. In this case the Guardian

name must be used.

For example /G/data02/ovpmexe/cm is rejected. Only the guardian name $data02.ovnpmexe.cm is allowed.

2-3-4 USERCFG SPN Sample

Few SPN declarations:

spn websvr /usr/tandem/webserver

+ /T8996V50_14JUN02_ABL_V516_1

spn webbin websvr/bin

spn weblog websvr/logs

Few instances using the previous SPN

program webbin/httpd ,trend=on

filesize weblog/access.log ,trend=off

Sample of SPN using OSS pathname with space character

spn operator /home/operator

spn opdocs operator”/my documents”

spn sysback operator/backup
