Hi,
I am looking for commands to get rrc message logs from enb to analyse ue to enb rrc messages. Requesting to share the commands to capture the logs for the same
Hi, @Sooraj, for that you can use Cell Trace subscription in ENM’s pmic app.
Hi @vlr9999 can you please tell me what needs to be done after this?
Hi @vlr9999 it is activated. Once the trace is completed do we need to go to shell terminal on scripting?
@Sooraj, yes. to decode result file connect to scripting VM and run decoder:
>lteCellTraceFileDecoder -h
usage: lteCellTraceFileDecoder [-h] [-nc] [-f {DEFAULT,JSON_FORMAT}]
[file_name]
LTE Celltrace Decoder - decodes LTE Celltrace files to a compressed csv format
Output directory will be /ericsson/tfd_cli_output/LTE_CELLTRACE
positional arguments:
file_name specify full path and name of the file to be decoded
optional arguments:
-h, --help show this help message and exit
-nc, --no_compression
disable compression for the current file
-f {DEFAULT,JSON_FORMAT}, --output_format {DEFAULT,JSON_FORMAT}
Output format of the decoded file
Full path to file must be specified
The disk usage volume is checked prior to decoding files and if the threshold is exceeded, no new files will be decoded until old files are deleted.
Decoder will skip already decoded files. File is considered decoded if a file with the same name and applicable extension exists in the output directory.
files will be distributed between pmic1 and pmic2
lteCellTraceFileDecoder -f JSON_FORMAT /ericsson/pmic1/CELLTRACE/pathtofile
lteCellTraceFileDecoder -f JSON_FORMAT /ericsson/pmic2/CELLTRACE/pathtofile
Hi @vlr9999 I have logged into scripting and changed the directory to /ericsson/pmic2/CELLTRACE . But when I gave ltecelldecoder it says command doesn’t exist
@Sooraj, perhaps it is not installed or you have no permissions.
Check for available deocders:
alias | grep -i decoder
or directory /ericsson/trace_file_decoder_cli/ content
Hi @vlr9999 this is what I am seeing
@Sooraj, got it, looks not so good. We have somthing different:
alias | grep -i decoder
alias decodeRncCtrFile='/usr/bin/python /ericsson/trace_file_decoder_cli/bin/runner.pyc --type RNC_CTR'
alias decodeRncGpehFile='/usr/bin/python /ericsson/trace_file_decoder_cli/bin/runner.pyc --type RNC_GPEH'
alias decodeRncUetrFile='/usr/bin/python /ericsson/trace_file_decoder_cli/bin/runner.pyc --type RNC_UETR'
alias imsiImeiAnonymization='/usr/bin/python /ericsson/trace_file_decoder_cli/security/bin/imsi_imei_anonymization.pyc'
alias listDecoderSupportedNrEvents='cat /ericsson/trace_file_decoder_cli/info/supported_nr_events.txt'

alias nrCellTraceFileDecoder='/usr/bin/python /ericsson/trace_file_decoder_cli/bin/runner.pyc --type NR_CELLTRACE'
alias nrUeTraceFileDecoder='/usr/bin/python /ericsson/trace_file_decoder_cli/bin/runner.pyc --type NR_UETRACE'
Contact your ENM team or support. Maybe that depends on contract with E///.

Thank you so much for your time and support @vlr9999. Let me see what I can do

Hi, @Sooraj, nice! Let’s try do decode something.
Hi @vlr9999 I tried, but I am getting permission error. I read in CPI that The output files are stored in the predefined location: /ericsson/tfd_cli_output/<TRACE_TYPE>/. No other output directory can be defined. When I checked my ENM I couldn’t see a path tfd_cli_output.
I guess, we need to provide read/write access? I can see tfd_cli_output available.
Yes, it is permissions issue.
