Comprehensive and Detailed Explanation From Exact Extract:

According to theSolarWinds Log Analyzer Administrator Guide (Version 2024.1), Log Analyzer provides several built-in or native log entry actions as part of its log-processing rules. The key native log entry actions include:

Add a tag to the log entry: This action allows you to tag event logs for easier searching and filtering later.

Continue rule processing but do not save: With this action, the log entry is not saved but rule processing continues.

Halt further rule processing for the log entry: Selecting this action will immediately stop the processing of any more rules for the current log entry.

Sending an email notification is an alert action and not considered a native log entry action in the context of log processing rules.

SolarWinds capacity forecasting accuracy improves when:

More historical data is used: The more historical data points included in calculations, the better the forecasting model will perform.

Using average daily values for calculations: This smooths out anomalies and provides a more accurate trend, as recommended in the documentation:

“To improve the precision of capacity forecasting, use as much historical data as possible and set calculations to use average daily values.”

Monitoring with platform agents or adjusting thresholds affects alerting, not trend accuracy.

If the web console shows a router as “down” but it is actually operational:

ICMP is blocked: If the polling engine cannot ping the device, it will be reported as down.

SNMP is blocked: If SNMP polling fails (for devices polled via SNMP), detailed data and status cannot be retrieved, resulting in a down state.

Agent connection issues may apply for agent-based monitoring but are not typical for network routers. Node dependency configuration could affect child node status display but would not cause the parent node to show “down”.

Comprehensive and Detailed Explanation From Exact Extract:

Accuracy is decreased: By increasing the polling interval, you reduce the frequency of path checks, which can cause the data to be less granular and less timely, reducing overall accuracy.

Probe is more likely to show all routes: With a longer interval, transient or temporary routes are less likely to be missed, and NetPath might display more complete route information over time.

The probe will still complete successfully; it is just executed less frequently. Accuracy is not increased with a higher polling interval.
