鑒于每個月需要把公司上千臺的服務的cpu使用利率，CPU負載，內存使用率、網(wǎng)絡流量等數(shù)據(jù)取出，以前是手動通過zabbix的平臺去獲取，每次都需要花費1-2小時才能完成這個需求，太耗時，因此優(yōu)化為systat軟件采集數(shù)據(jù)，然后通過python腳本處理/var/log/sa下采集到數(shù)據(jù)，然后入庫到MySQL數(shù)據(jù)庫中，以后每次取數(shù)據(jù)，只需要一行sql代碼就能獲取到數(shù)據(jù)，方便快捷，本文把采集數(shù)據(jù)的腳本截圖，如下所示：





最后附上完整代碼：
#!/bin/python2.7
#coding: utf-8
#################腳本用法:要取哪天的數(shù)據(jù)就輸入哪天的時間，比如9月1輸入應為20190901
