Graph Information

Field Internal name Type Warn Crit Info
CRC errors crc_error_down derive     The number of CRC (Cyclic Redundancy Check) errors on the downstream. Those are corrupted and thus lost packets that required resubmission, so these are bad.
FECS fecs_error_down derive     The number of FECS (Forward Error Correction Seconds) on the downstream, i.e. in how many seconds there were errors corrected by FEC. Those are errors that could be fully corrected from redundancy information by the modem, nothing was lost. These do not have a negative impact on performance, so they are pretty much irrelevant.
ES es_down derive     The number of ES (Errored Seconds) on the downstream, i.e. in how many seconds there were errors encountered
SES ses_down derive     The number of SES (Severely Errored Seconds) on the downstream
LOSS loss_down derive     The number of LOSS (Loss Of Signal Seconds) on the downstream
UAS uas_down derive     The number of UAS (UnAvailable Seconds) on the downstream
