Configure calculations and threshold settings in the SolarWinds Platform

This topic applies to all SolarWinds Platform products.

The following settings designate methods for calculating availability and transmission rate baselines, selecting the node warning level and counter type, and indicating security preferences for community strings and other potentially sensitive information in the web console.

Click Settings > All Settings, and in the Thresholds & Polling group, click Polling Settings to configure the settings.

Configure the way Orion computes selected performance metrics.

Setting Default value Description
Availability Calculation (advanced) Node Status Specify the type of calculation for determining device availability. See Calculate node availability in the SolarWinds Platform.

Baseline Calculation (advanced)

Selected Select this option to throttle traffic to routers for initial baseline calculation. See Baselines and baseline calculations in the SolarWinds Platform.
Enable Auto Dependencies Selected Select this option to enable periodical auto dependency calculation.
Enable Agent IP Address Deduplication Not selected Select to enable SolarWinds Platform Agent node deduplication based on IP address.

Allow Secure Data On Web (advanced)

Not selected

Select this option to see SNMP community strings in the SolarWinds Platform Web Console. For increased security, confirm that this setting is cleared.

This setting does not affect the display of custom reports that you export to the web.

Node Warning Level 120 seconds Specify the time period after which devices that do not respond to polling display in the SolarWinds Platform Web Console as Down.
Counter Rollover Method 2

Configure how counter rollovers will be handled. See Handle counter rollovers in the SolarWinds Platform.

  • If you use 32-bit counters, select Method 1.

    This method detects a rollover, and calculates based on it.

    First, the method checks whether the device rebooted and reset its counters to 0. In this case, the last value is 0.

    When it is a real rollover, we take the maximum value of the 32 or 64 bit number, take the difference between the maximum and the last polled value, and add it to the current polled value: (MaxValue - LastPolledValue) + CurrentPolledValue

  • If you use 64-bit counters, select Method 2.

    When a rollover is detected, Orion drops the poll and takes a new sample within 20 seconds. The new data point is stored, throwing the first data point away.

    In memory, we have the value from the previous poll (A) and the LastPolledValue (B). Because B < A, we detect counter rollover. Orion drops the last poll and does a fast poll within 20 seconds. The value stored in the database is calculated as C-B.

    Orion fully supports the use of 64-bit counters, but these counters can exhibit erratic behavior in some implementations. If you notice peculiar results, disable the use of 64-bit counters for the problem device, and contact the device manufacturer.

Default Assigned IP Address Empty Specify a default IP address assigned to monitored nodes if DNS resolution fails.
Disable HTML Encoding for Polled Data Not selected Select the option if you want polled data not to be encoded. Enabling this option is less secure.
