Instructions

 

Artikeloversigt: Denne artikel indeholder oplysninger om, hvordan du bruger Systemaktivitetsrapport, 'sar', for at se ydelsesoplysninger om SUSE Linux Enterprise Server (SLES).

 

Indholdsfortegnelse:

1. Installation
2. Konfigurer logføring
3. Brug af kommandoen 'sar'

 

1. Installation

  • Sørg for, at du er logget ind som "root"
  • 'sar' er adskilt fra 'sysstat')
    • # yast2 -i sysstat
  • Opret et symbolsk link til cron-jobbet:
    • # ln -s /etc/sysstat/sysstat.cron /etc/cron.d/sysstat.cron
  • Genstart cron-tjenesten:
    • # rccron restart

 

Tilbage til indholdsfortegnelsen

 

2. Konfigurer logføring:

  • Redigering '/etc/sysstat/sysstat' med din yndlingsredaktør
  • Find den linje, der starter med 'HISTORY='
  • Værdien repræsenterer det antal dage, logfilerne skal opbevares
  • Standard er tres dage, og du kan ændre det for at imødekomme dine behov
  • Logfiler gemmes i '/var/log/sa' vejviser

3. Brug af kommandoen 'sar'

BEMÆRK: Det tager mindst 10 minutter for cron-jobbet at blive kørt for at indsamle data, så denne kommando kan bruges.
  • Vis dags dag:
    • CPU statistik
  • # sar
  • Sådan angiver du en CPU, f.eks. CPU 3:
    • # sar -P 3
  • Kølængde og gennemsnitlig statistik:
    • # sar -q
  •  RAM-statistik:
    • # sar -r
    • # sar -R
  • Netværksstatistik:
    • # sar -n NAME
  • Erstatte NAME med et af følgende:
    • ALL – This displays all of the above information
    • DEV – Displays network devices vital statistics
    • EDEV – Display network device failure statistics
    • EICMP – Displays ICMPv4 network errors
    • EIP – Displays IPv4 network errors
    • EIP6 – Displays IPv6 network errors
    • ETCP – Displays TCPv4 network errors
    • ICMP – Displays ICMPv4 network traffic
    • ICMP6 – Displays ICMPv6 network traffic
    • IP – Displays IPv4 network traffic
    • IP6 – Displays IPv6 network traffic
    • NFS – Displays NFS client activities
    • NFSD – Displays NFS server activities
    • SOCK – Displays sockets in use for IPv4
    • SOCK6 – Displays sockets in use for IPv6
    • TCP – Displays TCPv4 network traffic
    • UDP – Displays UDPv4 network traffic
    • UDP6 - Displays UDPv6 network traffic
  • Udnyttelse af swapplads:
    • # sar -S
  • Disk statistik:
    • # sar -b
  • Personsøgning statistik:
    • # sar -B
  • Bloker enhedsstatistik:
    • # sar -d
  • Inode statistik:
    • # sar -v
  • Bytte statistik:
    • # sar -W
    • # sar -w
  • Statistik over systemskift:
  • Oplysninger i realtid kan også vises ved at tilføje interval- og heltalsargumenter:
    • Eksempel: Vis CPU-statistik hvert femte sekund i alt ti gange
    • # sar 5 10
  • Som standard viser kommandodisplayet 'sar' den aktuelle dags statistik, men du kan ændre det ved at bruge kontakterne -s for start og -e for end
  • Eksempel: # sar -s 12:00:00 -e 16:00:00
  • Dette viser CPU-statistikken for i dag mellem middag og kl. 16
