I feel alot of joy while exploring linux command-line tools, saidar is a very simple monitor tool for linux that I recommend to every system administrator. It does not offer many features and options as other tools avaiable to sys admins,but it does the job it is built for very well.
saidar is command-line text based utility that can be used to view system statistics available through libstatgrab.It offers information on the following system resources:
- network I/O
- disk I/O
- file system
The saidar utility also gives information on the name of the hostname, the time the system has been up and the actual date.
Do you like to install the saidar tool in your linux system? To install it in a debian based linux distribution open a terminal and run the following command.
sudo apt-get install saidar
If you use and rpm based distro such as Fedora,use the following command to install the saidar command-line tool in your machine.
sudo yum install statgrab-tools
Once the installation is finished you can easily get information on your system's resources by typing saidar in your terminal.The following output is displayed on my terminal screen after executing the saidar command.
Now that everything is set up,lets take a look at some options of the saidar tool that can help to offer a better experience.
The -c option enables coloured output.I find this option very useful because it makes the output look very nice and each area can be easily distinguished from the nearby fields.
The following screenshot shows how nice the output of the saidar tool looks when the saidar command is combined with the -c option.
The saidar utility updates the stats every three seconds by default.An option that can be used to change the delay second between updates does exist,it is the -d option.
You can use it in the same way I have used it in the following example.
saidar -d 1
As you guys can see from the above command,the refresh delay is now one second,but you can change it to the number of seconds you like.
A very good thing to do when using the saidar utility is to combine different options in order to get a better output.
saidar -c -d 2
The above command uses the -c option to enable coloured output and the -d option to change the delay between updates.
As I mentioned eariler in this article, there are not many options present in the saidar utility.There are two other useful options you may find useful while using this tool.
The -v option can be used to print the version number of the tool.
I get the following output while running the above command.
saidar version 0.17 Report bugs to .
The last option I would like to show in action is the -h option which is present in almost every command-line utility.The -h option is used to learn how to use the tool.
The following output is displayed in the terminal screen while running the above command.
Usage: saidar [-d delay] [-c] [-v] [-h] -d Sets the update time in seconds -c Enables coloured output -v Prints version number -h Displays this help information. Report bugs to .
The saidar utility it not complicated as other system monitoring tools,but if you are looking for an easy to use and simple utility for your linux box then make sure to have it in your toolbox.
