Jupyter Notebookメモ
CentOS7へのインストール。折角だからPython3系を利用してみる。 bashカーネルも入れておく。
yum install -y epel-release yum install -y python34 curl -L https://bootstrap.pypa.io/get-pip.py | python3 pip3 install jupyter pip3 install bash_kernel python3 -m bash_kernel.install jupyter-notebook
外部からアクセスするときは、下記のファイルを適宜編集。
~/.jupyter/jupyter_notebook_config.py
c.NotebookApp.ip = '0.0.0.0' c.NotebookApp.port = 8888
sarを表示
$ sar -A -o test.sar 1 10
などで取得したsarを表示するサンプルは、こんな感じ。
%matplotlib inline
import subprocess
from subprocess import Popen,PIPE
from datetime import datetime
import matplotlib.pyplot as plt
from matplotlib.font_manager import FontProperties
import matplotlib.dates as mdates
def readSarCPU(f):
args = ['/bin/bash','-c', "sadf -T -- -C " + f + " |awk '{print $3,$4,$6,$7}'"]
p = Popen(args,stdout=PIPE,stderr=PIPE)
out,err = p.communicate()
cpu = {'%user': [], '%nice': [], '%system': [], '%iowait': [], '%steal': [], '%idle': []}
timestamp = []
x = 0
prev = ""
for l in out.split('\n'):
if l == "":
break;
r = l.split(" ")
if prev != r[1]:
timestamp.append(datetime.strptime(r[0]+" "+r[1], '%Y-%m-%d %H:%M:%S'))
prev = r[1]
x = x+1
cpu[r[2]].append(float(r[3]))
return (timestamp, cpu)
def plot(x, data, title="",xlabel="",ylabel=""):
fp = FontProperties(fname='/usr/share/fonts/ipa-gothic/ipag.ttf')
if title!="":
plt.title(title, fontproperties=fp)
if xlabel!="":
plt.xlabel(xlabel,fontproperties=fp)
if ylabel!="":
plt.ylabel(ylabel,fontproperties=fp)
plt.xticks(rotation=30)
xfmt = mdates.DateFormatter('%m/%d %H:%M:%S')
ax = plt.gca()
ax.xaxis.set_major_formatter(xfmt)
for k in cpu.keys():
plt.plot(x,cpu[k], label=k)
plt.legend(prop=fp,bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.)
plt.show()
timestamp, cpu = readSarCPU("test.sar")
plot(x=timestamp, data=cpu,ylabel=u"%",xlabel=u"time")
