We are getting loads of Missing & Partial Responses in CEM, which causes SLA's of 40% to 60%. We know the cause; The TIM has loads of out-of-order bytes caused by packet duplication on the Spans. We have dedup turned on the MTP, but we still get a load of out-of-order bytes. The network team is planning on upgrading the current network infrastucture to account for the increase in SPANS across the network and reduce dupliation. This will take some time.
For now, I would like to disable the Missing & Partial Response Metrics in CEM. Accordin to the GUI, you can't disable them. However, you can ignore them "per transaction". This has been done and the Missing & Partial Response Defects are no longer showing up in the Incident Managent Window. However, the TESS agent in Introscope still reports them, and the SLA's in CEM remain the same, even though the Application shows no Defects in the Incdent Management.
Is there another way to disable tracking of Missing & Partial Responses in CEM? I've heard there may be way to do it by modifying the APM Database using some SQL. It would be nice to allow these to be disabled in the GUI.
