本文實例為大家分享了python腳本監控docker容器的方法，供大家參考，具體內容如下
腳本功能：
1、監控CPU使用率
2、監控內存使用狀況
3、監控網絡流量
具體代碼：
#!/usr/bin/env python
# --*-- coding:UTF-8 --*--

str=commands.getoutput(command)
container_counts_list=str.split('\n')
if sys.argv[1] not in container_counts_list:
print container_counts_list
print "你輸入的容器名稱錯誤，請重新執行腳本，并輸入上述正確的容器名稱."
sys.exit(1)
else:
container_name = sys.argv[1]
if sys.argv[2] not in keys_container_stats_list:
print keys_container_stats_list
print '你輸入的容器監控項不在監控范圍，請重新執行腳本，并輸入上述正確的監控項.'
sys.exit(1)
else:
monitor_item = sys.argv[2]
if sys.argv[3] not in merit_list:
print merit_list
print "你輸入的容器監控明細詳細不在監控范圍內，請重新執行腳本，并輸入上述正確的明細監控指標."
else:

monitor_docker(monitor_item,merit)

以上就是python腳本監控docker容器的全部代碼，希望對大家的學習有所幫助。
