Use the program cronttab to create cron jobs that: Append the output of the command uptime to a file in your home directory. This should run every 4 minutes. Appends the disk space used in /var to a different file in your home directory. Include the date and time in some way. This should run 8 times a day, evenly spaced throughout the day. You can choose the times. Make sure you are recording just the disk space used by /var, and not the disk space used by the entire partition that /var is on. Also, don't use human readable mode, since you will not be able to see any changes in the values if you do this. Runs a python program (which you have to write) that searches through the file created in step 1 and outputs any lines where the 5-minute load average first goes above 2.00 and then the next line where the 5-minute load average is back below 2.00. Save the results to a third file in your home directory. This program should run once a day between 3 and 5 am. (You should make sure that your system has a high 5-minute load average at least once so you can test your s

(You should make sure that your system has a high 5-minute load average at least once so you can test your script. See the program stress for a nice tool that can stress test your system.) For example, if the the 5-minute load averages were 0.00 1.53 2.67 3.99 2.02 1.75 0.98 2.13 1.88 Then you would output the entire lines containing 2.67, 1.75, 2.13 and 1.88 At the end of your Word document, include the answers to the following questions:
I'm stuck on the third part, my python script takes the uptime.txt file and pulls the ones where the average goes over 2.00, however, can't figure out how to record the first line after the average drops below 2.00 like the directions say.
My Script:
#!/usr/bin/env python
import os
def main():
highAVG = []
infile = open ('uptime.txt','r')
for line in infile.readlines():
line = line.strip()
nline = line.split()[-3:]
index = nline.pop(0)
index2 = nline.pop(0)
index3 = nline.pop(0)
avg = float(index.replace(',', ''))
avg2 = float(index2.replace(',', ''))
avg3 = float(index3.replace(',', ''))
if avg > 2.0:
highAVG.append(line)
if avg < 2.0:
highAVG.append(line)
elif avg2 > 2.0:
highAVG.append(line)
if avg2 < 2.0:
highAVG.append(line)
elif avg3 > 2.0:
highAVG.append(line)
if avg3 < 2.0:
highAVG.append(line)
infile.close()
outfile = open ('High_load_avg', 'w')
for line in highAVG:
print(line)
outfile.write(line + '\n')
outfile.close()
if __name__=='__main__':
main()
The output:
02:12:01 up 7 days, 5:28, 1 user, load average: 7.67, 4.06, 1.74
02:16:01 up 7 days, 5:32, 1 user, load average: 2.70, 4.65, 2.61
02:20:01 up 7 days, 5:36, 1 user, load average: 0.07, 2.09, 2.01
02:24:02 up 7 days, 5:40, 1 user, load average: 3.12, 2.07, 1.96
03:12:01 up 7 days, 6:28, 1 user, load average: 4.66, 1.93, 0.83
03:16:01 up 7 days, 6:32, 1 user, load average: 7.96, 5.30, 2.48
03:20:01 up 7 days, 6:36, 1 user, load average: 0.47, 3.32, 2.40
Between the first two lines, I need the line where the load average drops below 2.00
I've posted this question three times, the first two times they recycled the python script from a previous question asked by someone else. That script obviously doesn't work. The third time wasn't any help at all.
