My preparation notes for Wells Fargo interview-Geneos

Geneos layers and components

1. visualization layer -> active console
2. analysis and correlation layer -> gateways : hosted on central server, which does scheduled checks, rules
3. instrumentation layer -> netprobe : lightweight process hosted on application server, that collects the sample data and communicates to gateway


managed entity
dataview : the data that is collected by netprobe displayed as table called dataview
managed variable : a single cell in dataview

for each server to monitor in prod, 2 netprobes are required one in prod and other in dev/test environment

installing netprobes on server.

get NPCtrl file from repo -> this is DB internal tool

to restart netprobes
./NPCtrl -c restartAll

enable watchdog to restart if any probe is down
./NPCtrl -c watchdog ALLPROBES

1. add managed entity
