Nmon Analyzer For Windows

  

If you make use of Linux in your data center, then you have good reason to be on the lookout for a simple-to-use monitoring tool that can give you a quick rundown of what's going on with your server. Within the realm of Linux, tools like this are plentiful. So where do you start in your quest to find that perfect tool? For me, day-to-day monitoring of Linux servers begins with Nigel's Monitor, aka nmon.

NMON comes in two versions: nmon for 32-bit systems, and nmon64 for 64-bit systems. Since MicroStrategy Intelligence Server Universal is certified only for 64-bit systems, nmon64 should be used. Since MicroStrategy Intelligence Server Universal is certified only for 64-bit systems, nmon64 should be used.

After copying my nmon output file in my windows station, I just have to launch the excel file and then use the button Analyze nmon data And below I show some graphs made by the nmonanalyzer. Conclusion As we can see nmon is a very useful tool which can help monitoring our servers. It works also for Aix systems. Nmon provides CPU utilization, kernel-level values, memory and disk usage, and network information. The tool can display this data neatly and in real-time directly in your console, or it can save the data to a csv file that can be read into MS Excel using the nmon analyzer tool. To save nmon data to a csv file, run: nmon -F.nmon -t -s -c I have been using nmon extensively to analyze the performance and identify any bottlenecks in my database system. The nmon application can be installed from your distribution's standard repository. This means you should be able to install nmon without too much fuss. For a distribution that uses apt (Debian, Ubuntu, etc.), do the following: Open up your terminal window. Issue the command sudo apt-get update. Nmon – Wikipedia. This article needs additional citations for verification. There have beendownloads of nmon for Linux from SourceForge, showing it popularity and it is found in Linux operating System Repositories. The topic of this article may not nmon analyzer Wikipedia’s nmon analyzer guidelines for products and services. NMON Analyser ships with a Perl script to divide a long.nmon file into several shorter ones. Consult the NMON Analyser documentation that ships with the analyser for more details. NOTE: While nmon64 is running, it switches to a background thread and returns control to the shell. Download Java Nmon Analyser for free. The Java Nmon analyser is a free, open source analyser tool which is helpful in analyzing performance data captured using the nmon performance tool. And real-time monitor the Linux/AIX 's performance base on nmon.

The nmon tool will, using a simple ncurses interface, display the usage for CPU, memory, network, disks, file system, NFS, top processes, resources, and power micro-partition. What's best is that you get to choose what nmon displays. And since it's text-based, you can secure shell into your servers and get a quick glimpse from anywhere (as long as 'anywhere' has access to said server).

Let's install nmon and see how it is used.

Installation

The nmon application can be installed from your distribution's standard repository. This means you should be able to install nmon without too much fuss. For a distribution that uses apt (Debian, Ubuntu, etc.), do the following:

  1. Open up your terminal window
  2. Issue the command sudo apt-get update
  3. Install the software with the command sudo apt-get install nmon
  4. Allow the installation to complete

If you're using a distribution that uses dnf (Redhat, Fedora, CentOS, etc.), the following steps will install nmon:

  1. Open up your terminal window
  2. Issue the command dnf install epel-release
  3. Install nmon with the command dnf install nmon
  4. Allow the installation to complete

You are now ready to make use of nmon.

Usage

Now that nmon is installed, you can fire it up by issuing the command nmon. In the nmon window (Figure A), you simply have to toggle the statistic(s) you want to view.

Figure A

Say you want to view information about disks. If you hit the d key on your keyboard, nmon will display real-time statistics about any and all attached disks (Figure B).

Next we'll add network and memory to the mix by hitting the n key followed by the m key (on your keyboard). The resulting window will add those real-time statistics to the mix (Figure C).

You can toggle any of the added statistics off by hitting the associated keyboard key (the same used to add). The tool also includes the ability to increase and decrease the speed of updates. By hitting the - key on your keyboard you will speed up the screen updates and, conversely, the + key will slow them down.

Custom-made Chiptuning files My Chiptuning files supply custom-made ECU tuning files to tune petrol and diesel engines for performance and fuel efficiency. We have all the necessary tools and software you need to retune your engine yourself, whether you have a car, a van, a truck or a tractor. Chip tuning software.

To quit nmon, hit the q key and you will be returned to your bash prompt.

The tool also includes the ability to capture information and save it to a file. This can come in very handy if you need to monitor a system for a set period of time and then review the collected data later. Say you want to collect thirty rounds of information every 60 seconds. To do this, you would issue the command:

After issuing the above command you will find a file in the current working directory with the extension .nmon. Open that file to view the collected data.

Scheduling data collection

You could even create a cron job to schedule a regular dump of nmon-collected data (which could be handy for troubleshooting an recurring issue). A simple solution for this would be to create a bash script (we'll call it nmon.sh) that contained something like the following:

Save that file and give it executable permissions with the command chmod u+x nmon.sh. Now open crontab for editing with the command crontab -e and enter something like this:

Save and close crontab. The above cron job will run every day at 11:30 AM. Modify that to fit your needs and you have an easy solution for troubleshooting an issue occurring on your Linux data center machines.

Seriously useful, seriously simple

You'd be hard-pressed to find a simpler solution to a pressing need. With the help of nmon you can monitor your Linux systems in real time or collect data to be combed through at a later date. This tool should be considered a must-have for any Linux sysadmin.
