lastUptime: Stores the upTime from the previous poll.uptime: (TimeTicks) - SysUpTime (.1.3.6.1.2.1.1.3.0) - The time in hundredths of seconds since the device was last reinitialised.This can be measured value from your own speed test, or you might query the interface speed, or in the of (A/V)DSL you might query the sync speed adslAtucChanCurrTxRate (.1.3.6.1.2.1.10.94.1.1.4.1.2.4) again for interface 4.

downSpeed: (Gauge) - The maximum possible download speed in bps (bits per second).lastInOctets: Stores the inOctets from the previous poll.inOctets: (Counter32) ifInOctets (.1.3.6.1.2.1.2.2.1.10.4) - Amount of bytes received on the specified interface, 4 in this example.What does this mean? Well lets explain the variables: Note: Calculation will be incorrect if inOctets counter has wrapped.Д«andwidthUtilisationPercent = (( float)((inOctets - lastInOctets) * 8) / ( float)(downSpeed * ((uptime - lastUptime) / 100)) * 100) Which can be performed with the following: For example if I want to calculate the bandwidth utilisation of my ADSL connection, then we need to look calculate: Utilisation = Amount of Data in time period / Max Possible data in time period As such your poll interval shouldn't be used for any calculations of time, instead using the devices uptime counter will show the time elapsed between data collections. SNMP responses are often deprioritised by devices when under load. It's important to note that even if you make GetRequests every n seconds, that the response may not arrive in the allotted time period. Working With SNMP Data Time Based Measurements Though I expect there are limits on the maximum packet sizes, so some experimentation may be required with large numbers of OID. You can add multiple OID to be queried in a single request by calling snmpRequest.addOIDPointer(another_callback) This approach ensures all the requested OID are returned in the same response. Display response (first call might be empty) if ((timeLast + pollInterval) <= millis()) Check to see if it is time to send an SNMP request.
