Standard ifInOctets/ifOutOctets are 32-bit counters that wrap around 4,294,967,296 bytes (~4.3 GB). At 1 Gbps this wraps every ~34 seconds, causing brief drops to 0 bps in traffic charts and capacity reports. When prev > 2^31 and delta is negative, add 2^32 to recover the correct rate. If the result is still negative (HC 64-bit counter after reboot), clamp to 0. Small-value decreases (prev < 2^31) continue to clamp to 0 since they cannot be real 32-bit wraps. Fixes both capacity.ex (utilization reports) and device_live/show.ex (per-device traffic chart). Reviewed-on: graham/towerops-web#161 |
