Errors when trying to integrate UIM with OI to send use apm_bridge probe to send inventory data

Environment

Release : 20.2

Component : CA DOI AUTOMATION INTEGRATION

UIM 20.4 

apm_bridge 1.0.7

Cause

The OI TAS endpoint was configured as a secure route (HTTPS) but the apm_bridge probe was not enabled to use SSL

 

Resolution

The OI is configured with a self-signed certificate which needs to be imported into UIM truststore

In apm_bridge.cfg, enable SSL

use_ssl = true

Steps to get the .cer of apmservices gateway

Browser route:
1)Access the apmservicesgateway URL from chrome browser and export the public key
2) Click on Not Secure icon on the browser click on Certificate(invalid)-->Click on Details-->Click on Copy to File-->
Click Next-->Select Base-64 encoded X.509(.CER) option-->Click on Next-->Provide filename with .cer extension-->Click on Save

Through openssl use the following command to extract the public key:
echo -n | openssl s_client -connect apmservices-gatewayroute:443 -servername apmservices-gatewayroutename \
| openssl x509 > /root/folder/pub.cer

 

Steps to add public key of apmservices gateway to the UIM key store:
1)Move to C:/Progra~2/Nimsoft/jre/jre8u282b08/bin folder
2)keytool -import -alias umpcert -keystore "C:/Progra~2/Nimsoft/jre/jre8u282b08/lib/security/cacerts" -file "C:/path to the folder/filename.cer"
3)provide the password as changeit
4)add certificate to the keystore by typing yes
5)once done restart apm_bridge probe and check for the logs.
