Data apa yang sedang dikumpulkan?

Cantumkan penghitung kinerja dan jenis objek yang dikumpulkan (Proses, Memori, Prosesor).

Perf
| summarize by ObjectName, CounterName

Penggunaan memori dan CPU

Buat bagan memori dan CPU yang digunakan komputer, selama satu jam terakhir.

Perf
| where TimeGenerated > ago(1h)
| where (CounterName == "% Processor Time" and InstanceName == "_Total") or CounterName == "% Used Memory"
| project TimeGenerated, CounterName, CounterValue
| summarize avg(CounterValue) by CounterName, bin(TimeGenerated, 1m)
| render timechart

Hitung pola penggunaan CPU di semua komputer, bagan menurut persentil.

| summarize avg(CounterValue) by bin(TimeGenerated, 15min), Computer, _ResourceId // bin is used to set the time grain to 15 minutes
| render timechart
// Perf table stores performance counters for Windows and Linux computers
// Counters are specified using ObjectName (performance object), InstanceName and CounterName
// % Processor Time captures CPU activity, ObjectNames can be Processor, Process and Process Information
