Linux Script

Hello,

Can I get a linux Red Hat script to monitor resources such as:
- top consuming resources
- memory and swap usage
- CPU utilization
- disk space usage
- network monitoring
I would like the output written to a file every hour. Basically this would be a snapshot of the server and some help with the formatting to make it better to read would be apreaciated.

Thanks.

#!/bin/bash
date +"%m-%d-%y %H%M" >> foo.txt
top -abcn 1 >> foo.txt
free -m >> foo.txt
iostat -cd 1 2 >> foo.txt
vmstat -tw 1 2 >> foo.txt
df -h >> foo.txt
ifconfig eth0 >> foo.txt

Open in new window


this will provide a few different things

the first line will echo the current date and time to the file

top will show output of processes; in this case sorted by memory usage (RES column)

free will show free physical memory, swap usage, buffers and file cache

iostat will show some disk statistics; vmstat will show memory/cpu statistics

note that both iostat and vmstat by default will show totals since last reboot on the first output which is why the command has a 2 indicating it will run twice; first total since reboot and second current statistics

df will show free space and ifconfig will show the output of the network interface (change to what interface you want or just the command itself for all interfaces).  not sure what exactly you're looking for with this but it will show packet statistics.

to run hourly just add this in crontab
* */1 * * * foo.sh

also, if you get command not found for iostat and vmstat, they are both part of sysstat package so you can install that if it isn't already
