Outside Discovery 5


SAP AG 2008

1 Overview

The purpose of the Outside Discovery is to automatically discover, collect and send information related the monitored

system to Solution Manager.

As of Solution Manager 7.1 SP06, Outside Discovery is able to collect following information:

Host: data related to Physical Host and Virtual Host (like Operating System type, version, cpu, memory

)

Database: data related to installed database (like database type, version, )

Microsoft Internet Information Service: data related to installed instance of Microsoft IIS (like .Net

version, IIS Applications, IIS Sites)

The Outside Discovery is packaged inside the Diagnostics Agent within the Agelet called DCC (agelet archive:

sap.com~tc~smd~agent~application~e2edcc.ear).

The Outside Discovery process relies on the SAPHostAgent Web Service process for collecting all raw technical

data related to monitored system.

The process is ready to push as soon as the running Diagnostics Agent gets connected to a Solution Manager

system. Data are:

o Collected from the SAPHostAgent Web Service.

o Filtered and cached on Agelet side.

o Sent to JAVA Bean Controller (SMD_DataEnrichment_Registrator) through P4 Connection.

o Stored in LMDB database (AI_DIAGSNOTICS_DATA_ENRICHMENT package).

Outside Discovery 6


SAP AG 2008

2 Pre-requisites

Even if the Outside Discovery process itself do not require any specific setup in order to run some pre-requisites are

necessary.

Pre-requisites for the SAPHostAgent and Diagnostic Agent are detailed in the Solution Manager Guided Procedure:

SAP Solution Manager Configuration System Preparation Step 6.3: Prepare Outside Discovery

Implementation Guides (IMG) are available in Solution Manager.

o Here is the output from the above command:

2.1.2 SAPHostAgent Porttype

The SAPHostAgent provides a Web Service access to some sub-services also called Porttype. The SAPHostAgent

should be configured in order expose those Porttype to the Web Service.

The configuration of those available services is defined in the following file host_profile located under of the binary

directory of the SAPHostAgent.

Following porttypes are mandatory for the Outside Discovery process:

o SAPHostControl

2.1.3 SAPHostAgent Trusted Connection

Some methods within the SAPHostAgent are restricted. In order to allow the Diagnostics Agent to access protected

Web Service from the SAPHostAgent a trusted connection is necessary between the 2 parties.

Trusted connection is defined in the following file host_profile.

The Diagnostics Agent user should be entered in the specific field service/admin_users.

Example of host_profile file on Windows system:

2.2 Diagnostics Agent

In order to start the Outside Discovery process, the Diagnostics Agent should be connected to the Solution Manager

System:

o Either during the Diagnostics Agent installation procedure.

o Either using the following step in the System Preparation Guided Procedure:

Outside Discovery 9


SAP AG 2008

3 User Guide

As soon as the Diagnostics Agent gets connected to a Solution Manager system, the Outside discovery agelet

starts running.

The Outside Discovery Agelet contains 3 different jobs:

Host Discovery: this job is retrieving data from physical and virtual host on the monitored system.

Database Discovery: this job is retrieving data for all installed database on the monitored host.

IIS Discovery: this job is retrieving data for installed Microsoft IIS on monitored host.

The Host Discovery process is the master process of the Outside Discovery Agelet. Database

Discovery and IIS Discovery processes are only started if Host Discovery has been able to

successfully push and create host entity on Solution Manager.

3.1 Host Discovery

The Host Discovery (aka PhysicalHostPushJob) is the master process and gets started first.

The Host Discovery is retrieving following data from the monitored system:

Physical Host this includes:

o Operating System Information

o Virtualized Solution used.

All Logical hosts defined on the monitored Physical Host.

3.1.1 Landscape Browser / Technical System Editor View

All hosts created by the Outside Discovery process are available in the Landscape Browser and the Technical

System Editor.

In the following example, Outside Discovery retrieved following information from a Diagnostics Agent installed

on physical host vml2262:

Landscape browser:

Outside Discovery 10


SAP AG 2008

Physical Host vml2262 is using a Virtualization solution.

o Its Operating System is SUSE Linux Enterprise Server 10 (x86_64)

o its Full Qualify Domain Name is vml2262.wdf.sap.corp and its IP Address is 10.66.51.11

Logical Host ldai1sd7 is defined within this physical Host:

o Its Operating System is SUSE Linux Enterprise Server 10 (x86_64)

o its Full Qualify Domain Name is ldai1sd7.wdf.sap.corp and its IP Address is 10.66.51.53

More detailed data are available in the Technical System Editor like Alternative Hostnames, CPU Type.

Complete list of data is available using the Details button:



SAP AG 2008

3.1.2 Host Discovery Process Status

The status of the Host Discovery Process is displayed within the Landscape Browser (column Host Status).

Here is a view of the Host Discovery Process running on Physical Host vml2262

Host Discovery run successfully for physical host vml2262

Version of the SAPHostAgent is Kernel version 720 and Patch Number 80.

3.1.3 Physical Host Data

Following data are retrieved for the Physical Host:

Physical Host fields Description

Name Short name of the physical host

Full Host Name Full Host name of the physical host

IP Address IP Address

Virtualized Solution Identify if the physical host is running inside a virtualized

solution.

List of fields retrieved from the monitored host:

Operating System data Example

OpSysUname Windows NT OpSys WINDOWS_X86_32 OpSysRelease 5.2



SAP AG 2008

OsSysBits 32 OpSysCategory Windows NT OpSysReleaseName Windows NT 5.2 Manufacturer PC Vendor PhysicalRAMinMB 3904 VirtualRAMinMB 12276 NumberofCPUs 4 CPURate 2799 CPUCache CPUType Intel 801586 (Mod 2 Step 9)

3.1.4 Logical Host Data

The Outside Discovery process is retrieving all Logical Hosts from the installed SAP Product Instance: SAP J2EE

Engine, Diagnostics Agent, etc

Logical Host fields Description

Name Short name of the logical host

Full Host Name Full Host name of the logical host

IP Address IP Address

The Logical Host inherits from the same Operating System data as its Physical Host.

Logical Host for SAP Instances

Logical Hosts are retrieved from the SAPHostAgent which reads the SAP Profile. If the Full Qualified Domain

Name is not reported correctly then the property SAPLOCALHOSTFULL= in the SAP Profile should be

modified manually in order to match your network configuration.

Logical Host for non-SAP Instances

For non-SAP Instances, Logical Hosts are retrieved from the Diagnostics Agent.

This means installing a Diagnostics Agent on the Logical Host is necessary in order to get the logical host reported

correctly to LMDB by Outside Discovery. This is usually part of the installation when enabling the monitoring

capabilities of the 3rd

Party Component.

The important point is that the host, FQDN and IP should be the one defined for the Logical Host.



SAP AG 2008
