Re-processing already captured data with a new version of Packetscope2 can be useful. The following steps demonstrate how to do this.
Step 1) Generate list of captures to process
Using the command
fmadiocli "show capture list"This will list all captures on the system.
Example shown below
fmadio@fmadio100v2-228U:/mnt/store0/tmp2$ fmadiocli "show capture list"
fmad fmadlua Sep 7 2024 (/opt/fmadio/bin/fmadiolua --nocal /opt/fmadio/bin/fmadiocli show capture list )
Disable cycle calibration

.In this example we want to process 2 captures named
ny2-election_20250125_1550
interop_full_20250109_1538 Step 2) list of captures in a file
create a file, in this case file_list and place the names of captures to be processed one line at a time.
An example is shown below
fmadio@fmadio100v2-228U:/mnt/store0/tmp2$ cat file_list
ny2-election_20250125_1550
interop_full_20250109_1538 Step 3) Run batch processing script
Run the batch processing script with the format
pscope2_batch.lua <file path of list>Example is shown below
fmadio@fmadio100v2-228U:/mnt/store0/tmp2$ pscope2_batch.lua ./file_list
fmad fmadlua Sep 7 2024 (/opt/fmadio/bin/fmadiolua /opt/fmadio/bin/pscope2_batch.lua ./file_list )

.This will continue to run until all files have been processed and updated. This may take some time depending on how much data has been processed.
Step 4) Confirm data
Confirm all data is present in Grafana after processing has completed.
