Unrecognized OPP PDM sample name 11 or 12

Products

• ASG-S200

Issue/Introduction

Event logs are full of the following messages:

2023-04-23 17:09:10+04:00+04  "Warning: Unrecognized OPP PDM sample name  11  "  0 160000:65  opp_statistics_sampler.cpp:54
2023-04-23 17:09:10+04:00+04  "Warning: Unrecognized OPP PDM sample name  12  "  0 160000:65  opp_pdm_stats_controller.cpp:262

Environment

ASG had been upgraded to version 7.3.12+ and then downgraded back to lower version

Cause

PDM samples with names 11 and 12 were introduced in versions 6.7.5.20+ and 7.3.12+ and mean the following:

    {"OPPS1.18", "Total aborted transactions by client", "%," PRIu64},
    {"OPPS1.19", "Total aborted transactions by server", "%," PRIu64}

After downgrading the system back, those samples are not cleared from the disk which causes PDM sampler to raise warnings about unrecognized samples.

Resolution

There is no workaround. Warning messages may be safely ignored.

The estimated fix release is 7.3.15.

Additional Information

Clearing statistics using this procedure does not help.
