Glance Adviser Script - Averaged over # of CPU's

sábado, 21 de julho de 2012

The following script will return the average CPU utilization (averaged over number of CPU's) for system, user and total utilization.  It could easily be modified to be a feed into MRTG for graphing purposes.

#
# Sample glance script showing average CPU utilization across all CPU's
#
headersprinted = 0
total_total = 0
total_sys = 0
total_user = 0
count = 0
# For each CPU
cpu loop {
    # print headers if this is the first row
    if headersprinted == 0 then {
      print "   Sys CPU   User CPU  Total CPU"
      headersprinted = 1
    }
    total_total=total_total+GBL_CPU_TOTAL_UTIL
    total_sys=total_sys+GBL_CPU_SYS_MODE_UTIL
    total_user=total_user+GBL_CPU_USER_MODE_UTIL
    count = count + 1
  }
print total_sys/count, " ", total_user/count, " ", total_total/count

Output
# glance -j 5 -adviser_only -syntax cpu.cfg -iterations 3
