Overview

There are cases where CA PM administrators need the ability to export Discovery Profiles (DP) from Data Aggregator for later import into the same or another instance.

Use cases include

• Transfer DP from test to production system
• Cleanup profiles
• Export DP for scripted updates (like adding/removing hosts, changing SNMP profiles etc)
• Broken DA/DR and the need to set up a new instance 

Approach

Two Perl scripts are provided: exportProfiles.pl and importProfiles.pl.
Both scripts use the DA REST interface to access the following entities:

• SNMP profiles: retrieved to lookup the profile name (during export) and profile id (during import)
• IP Domain list: retrieved to lookup the profile name (during export) and profile id (during import)
• Discovery Profiles: retrieved and saved to xml file during export; created from xml file during import

Assumptions

SNMP profiles and IP Domains are not exported/imported. They are hosted by CA PC and we assume they exist on the target system under the same name.

They are as well covered by mysql netqosportaldb export/import.

While the names are the same in export and import environment, the IDs could differ. During export, an association file is created with the SNMP profile name and IP Domain name for each Discovery Profile. During import, the SNMP and Domain IDs are being looked up on the target system, they replace the stored IDs in the discovery profile for the import.

Limitations

The scripts operate only for the single default tenant.

Prerequisites

• Perl 5.18 or better
• Modules REST::Client, XML::LibXML
• Access to http://DA-HOST:8581/rest

Both scripts have been tested with Strawberry Perl on Windows and are in use by customers.

Usage

perl exportProfiles.pl DA-HOST:8581 discPrfExp.xml profileAssociations.csv

DPName, ID, Name, ID, Type
DPwithv3,2147,sysedge,2112,SNMPv1
DPwithv3,2147,v3Prof2,2146,SNMPv3
DPwithv3,2147,v3Prof1,2145,SNMPv3
DPwithv3,2147,Default Domain,2,DOMAIN

perl importProfiles.pl DA-HOST:8581 discPrfExp.xml profileAssociations.csv

Importing ...
DPname, Name, ID, valid, Type
DPname --------------------------------------- POST: RC
DPwithv3, Default Domain, 2, 1, DOMAIN
DPwithv3, sysedge, 2112, 1, SNMP
DPwithv3, v3Prof2, 2146, 2, SNMP
DPwithv3, v3Prof1, 2145, 3, SNMP
DPwithv3 --------------------------------------- POST: 200

Files:

Discovery profile export file:       discPrfExp.xml
Associations file:                              profileAssociations.csv
discovery profiles to import:       out- discPrfExp.xml         (importProfiles.pl)

Testing options for importProfiles.pl

-          Pass 4^th parameter (hidden debug switch) with value 1 or 2:

o   1: Write generated Discovery Profiles to file only, no POST to DA
(output: not POSTed)

o   2: Append “-2” to the Discover Profile name, e.g. for import into same DA

Error handling during import

-          If SNMP profile names or IP Domain names that are saved in the associations file cannot be found on the target system, the discovery profile is not valid and does not get imported
