4119214

Description: In case of pulling telemetry data from the UFM server (High or low-frequency instances), the loopback/local host IP should be used instead of the hostname or host IP.

Example of High-Frequency (Primary) Telemetry Instance:

            

            
#curl -s 127.0.0.1:9001/csv/cset/converted_enterprise
        

Example of Low-Frequency (Secondary) Telemetry Instance:

            

            
#curl -s 127.0.0.1:9002/csv/xcset/low_freq_debug
        

Keywords: Localloop IP, Telemetry, Local Host

Workaround: N/A

4151847

Description: Primary Telemetry is not updated properly

Keywords: Primary Telemetry

Workaround: Comment out or remove the line that defines CLX_RESTART_FILE in the /opt/ufm/files/conf/telemetry/primary_env.cfg configuration file. This change should be made before starting UFM.

If UFM is already running, restart the telemetry service for the change to take effect by running /etc/init.d/ufmd ufm_telemetry_restart.

Description: The High-Frequency (Primary) Telemetry instance is missing the necessary environment variable in UTM (non-legacy) mode, which causes an incorrect sample rate.

            

            
CLX_EXPORT_API_BASE_FREQ=1
        

Keywords: Telemetry

Workaround:

1. Add the following line to the file /opt/ufm/files/conf/telemetry_defaults/primary_env.cfg:

            

            
CLX_EXPORT_API_BASE_FREQ=1
        

1. Afterward, execute the command:

            

            
/etc/init.d/ufmd ufm_telemetry_restart
