Summary  
This chapter covers implementing code to collect and analyze key performance metrics (bandwidth usage, latency, packet loss, uptime), evaluate them against thresholds, and trigger alerts for proactive monitoring.

General domain of usage  
Network administration

Overvågning af netværksydelse er afgørende for at sikre et stabilt og effektivt netværk. Det indebærer sporing af nøgleparametre såsom båndbreddeforbrug, latenstid, pakkebortfald og oppetid for at opretholde optimal funktionalitet. Denne proaktive tilgang gør det muligt for netværksadministratorer at forudse og løse problemer, før de forstyrrer brugerne.

Effektiv netværksovervågning bør omfatte disse parametre. Værktøjer som SolarWinds, PRTG og Zabbix giver administratorer mulighed for at tilpasse dashboards, der viser netværkets tilstand, sætte præstationsgrænser og automatisere advarsler om potentielle problemer. Disse avancerede overvågningsværktøjer giver indsigt i trafikmønstre, hvilket gør det muligt for administratorer at optimere ressourceallokering og håndtere flaskehalse.
