Powershell mehrer Werte in Text suchen und in CSV oder TXT ausgeben

Ich habe das Problem dass ich aus einem Log das als txt vorliegt mehrere Werte auslesen soll und in einer txt oder csv zu speichern, das ganze soll mit Powersehll verwirklicht werden.

Das "Writung" im Ergebnis unten soll aus der Zeile mit dem Beginn 16 threads.. stammen und die z. B. "8K" aus der nachfolgenden Zeile.

Habe schon einiges getestet aber ohne Erfolg und auch schon ordentlich im Netz gesucht.

Danke schon mal für euere Tipps
