The Counter Rollover setting configures SolarWinds SAM to properly handle counter rollovers. SolarWinds SAM is capable of handling either 32-bit or 64-bit counters, but, by default, SolarWinds SAM assumes counters are 32-bit. 32-bit counters have a maximum value of 232, or 4,294,967,296, and 64-bit counters, if they are supported by your network devices, have a maximum value of 264, or 18,446,744,073,709,551,616.

Note: The 32-bit counters option is designated as Method 1 in the Counter Rollover field on the SolarWinds Polling Settings page.

Designating the type of counter used by SAM

You may need to log in with an administrator account to perform this action.

  1. On the web console, navigate to Settings > All Settings > Polling Settings.
  2. If you are using 64-bit counters, select Method2 in the Counter Rollover field in the Calculations & Thresholds area.
    • If Method 2 is selected, SolarWinds SAM intentionally skips a poll if a polled value is less than the previous polled value to permit counting to 264.
    • SolarWinds fully supports the use of 64-bit counters; however, these 64-bit counters can exhibit erratic behavior in some implementations. If you notice peculiar results when using these counters, disable the use of 64-bit counters for the problem device and contact the device manufacturer.
  1. If you are using of 32-bit counters, select Method 1 in the Counter Rollover field in the Calculations & Thresholds area.
    Note: If Method 1 is selected, when a rollover is detected, the time between polls is calculated as (232  Last Polled Value) + Current Polled Value.
