Please some one help me out .
How to write a shell cript to monitor cpu usage vmstat and in Redhat linux .
vmstat out put should be in percentage.
Thanks in advance !!!!
I run iotop and vmstat on a CentOS server. Under some load the iotop swapin column starts to display values around 5% to 20% for some processes. But vmstat si an so remain zero. I thought that vmstat si and iotop swapin would both reflect swapping. How can si be zero while iostat shows significant swapin?
I m trying to store the output of vmstat 1 10 into a database.
I have done the necessary homework to connect bash to interact with the database.
1)storing the output of vmstat 1 10 to a file named abc.txt
2)I m applying a filter to vmstat to get desired output containing cpu(user),cpu(system),cpu(idle) values.
Hi I'm using vmstat to track machine performance during some tests (jmeter).
This is virtual machine running on some big strong machine, where lots of other virtual machines are installed (about 20 virtual machines).
I'm using flowing software versions:
vmstat -V: procps version 3.2.7
uname -a: Linux cmbpm 2.6.32-042stab044.11 #1 SMP Wed Dec 14 16:02:00 MSK 2011 x86_64 x86_64 x86_64 GNU/Linux
In Windows I use the Performance Monitor to see how much CPU, memory etc my server is using. Is there something similar to see percentage of memory use, percentage of CPU use etc for Linux? (other than vmstat) What is the best for real time analytics for Linux?
