Issue/Introduction

I am attempting to change the names of ICMP Response path tests to more meaningful values. I have attempted to use the ./update_alias_name.sh script, but found it only appears to work for devices, and not for Response Path Tests, which appear to be an attribute, or related component of a device. 

Attempting to run the script with -T component generates the following errors:

[[email protected]<PortalHost> bin]# ./update_alias_name2.sh -h <PortalHost> -u admin -p <adminPasswd> -T component -o ComponentList.csv

Command to get list of device:
curl -k -s -X get "https://<PortalHost>:8182/pc/center/webservice/devices" -u admin:<adminPasswd> > FILENAME

Command to parse out device ids:
xmllint --shell <<<"xpath /devices/device/itemId/text()" FILENAME | grep content= | sed s/^[^=]\*=//

The same problems are seen when using -T interface.

It returns one error line per managed device it queries until it exits.

No data is added to the XML export file specified.

Cause

Problems in the script were identified that caused the errors.

Environment

All supported DX NetOps Performance Management releases r21.2.3 and older

Resolution

Changes to the update_alias_names.sh script are required. There are numerous changes.

These changes are being made by the engineering team via defect DE514189. The updated and fixed script was added to the r21.2.4 release. Upgrade to r21.2.4 or newer to get the new script.

To resolve this now, without waiting for a new script in the r21.2.4 or newer releases, complete these steps.

1. Download the attached new_update_alias_names.gzip file to the Portal server. Extract it using "gunzip new_update_alias_names.gzip".
2. Run the following command (default path used) and not the ownership and permissions for the existing update_alias_names.sh script.
   • ls -al /opt/CA/PerformanceCenter/Tools/bin/update_alias_name.sh
   • Sample output from a default 21.2.1 lab would be:
     
     [[email protected]<PortalHost> bin]# ls -al /opt/CA/PerformanceCenter/Tools/bin/update_alias_name.sh
     -rwxr-xr-x 1 root root 19769 Sep  8 14:37 /opt/CA/PerformanceCenter/Tools/bin/update_alias_name.sh
     [[email protected]<PortalHost> bin]#
     
     
3. Rename the existing script so it's no longer used. The following command can be used.
   • mv update_alias_name.sh update_alias_name.sh_old_doNotUse
4. Copy the new_update_alias_name.sh script to (default path used) /opt/CA/PerformanceCenter/Tools/bin.
5. Rename it using "mv new_update_alias_name.sh update_alias_name.sh".
6. Ensure the updated script has the same ownership and permissions as the original.

The updated script should now work for both -T interface and component arguments.
