The SNMP byte counters for eth0 are inaccurate
The SNMP byte counter for eth0 RX (OID: 1.3.6.1.2.1.2.2.1.10) appears to be inaccurate.
For example, the counter value after reset for 1.3.6.1.2.1.2.2.1.10.2 is 926,851,356 (approximately 900 MB), whereas the data statistics for wireless clients indicate a total of 2.6 GB of received bytes.
I need to monitor a dozen of these models, so it's essential to understand how to collect accurate data from them.
@terziyski Thank you for your response. However, if there is intercommunication among the wireless devices, the Received Bytes and Sent Bytes should be approximately equal. From the image below, the total Received Bytes is 2.8GB, while the Sent Bytes are significantly higher at 25GB.
Additionally, the SNMP walk shows the following values:
- 1.3.6.1.2.1.2.2.1.10.2 (eth0) counter: 1,485,658,512 (approximately 1.5GB)
- 1.3.6.1.2.1.2.2.1.16.2 (eth0) counter: 2,020,978,492 (approximately 2GB).
If intercommunication among the wireless devices were taking place, the Received Bytes should not be significantly lower than the total Sent Bytes of 25GB.
