Comprehensive and Detailed Explanation From Exact Extract:
To edit trigger conditions for flow alerts in SolarWinds, the SolarWinds Query Language (SWQL) is required. SWQL is a proprietary subset of SQL designed specifically for the SolarWinds Orion Platform. The documentation specifies:
"Editing advanced alert trigger conditions and custom queries for flow-based alerts requires the use of SWQL, not PowerShell, Python, or standard SQL." References:

Comprehensive and Detailed Explanation From Exact Extract:
If only response time and packet loss are visible, the node is currently being polled via ICMP (ping), which does not provide detailed statistics like CPU, memory, or interface data. Switching the polling method to SNMP enables SolarWinds to gather detailed device metrics and statistics, as SNMP supports comprehensive monitoring.

Network Performance Monitor Administrator Guide, "Enabling Detailed Polling with SNMP,"
"ICMP polling provides only basic availability and latency. Use SNMP polling for detailed statistics."

Comprehensive and Detailed Explanation From Exact Extract:
Device Studio pollers offer more advanced capabilities than traditional Universal Device Pollers (UDPs).
While both can poll SNMP-enabled devices, Device Studio pollers can gather additional node details (such as chassis information and advanced device metrics) that UDPs are not able to access. UDPs are limited to polling OIDs and displaying simple numeric or textual values. The official documentation states that Device Studio expands the range of supported technologies and provides access to more detailed device information compared to UDPs.
