### Example2: simple sub-second monitor (ministat)
### This is a quick example showing how to implement your own *stat utility
### If you're interested in such functionality, contact me at dag@wieers.com
import sys
sys.path.insert(0, '/usr/share/dstat/')
import dstat, time
### Set default theme
dstat.theme = dstat.set_theme()
### Allow arguments
try: delay = float(sys.argv[1])
except: delay = 0.2
try: count = int(sys.argv[2])
except: count = 10
### Load stats
stats = []
dstat.starttime = time.time()
dstat.tick = dstat.ticks()
for o in (dstat.dstat_epoch(), dstat.dstat_cpu(), dstat.dstat_mem(), dstat.dstat_load(), dstat.dstat_disk(), dstat.dstat_sys()):
try: o.check()
except Exception, e: print e
else: stats.append(o)
### Make time stats sub-second
stats[0].format = ('t', 14, 0)
### Print headers
title = subtitle = ''
for o in stats:
title = title + ' ' + o.title()
subtitle = subtitle + ' ' + o.subtitle()
print '\n' + title + '\n' + subtitle
### Print stats
for dstat.update in range(count):
line = ''
for o in stats:
o.extract()
line = line + ' ' + o.show()
print line + dstat.ansi['reset']
if dstat.update != count-1: time.sleep(delay)
dstat.tick = 1
print dstat.ansi['reset']
