Preparing a Ganglia gmond native Windows binary This page is for collecting ideas about how to compile a native Windows version of gmond. The current version of gmond on Windows is compiled as a Cygwin application. This means that it depends on (and is limited by) the Cygwin environment and DLL for performing some C library functions and providing an interface to system metrics. A native binary reads the system metrics directly from the OS, using a mechanism known as WMI provided by the OS vendor. Compiling The Cygwin binary is compiled by the GCC binary included with Cygwin. Various other GNU tools (autoconf and friends) are also included in Cygwin, and used to prepare the source tree for a Cygwin build in much the same way as they are when building in a real UNIX environment. For building a native binary on Windows, these options are available: Tools Benefits Disadvantages CYGWIN versions of GNU tools GCC, autoconf, automake, etc (using GCC's -mno-cygwin for `cross compiling' a non-Cygwin binary) Consistency with the UNIX build procedure Microsoft Visual C Popular tool among Windows developers.
Includes Windows headers and stuff relating to WMI. Requires duplication of the makefiles Microsoft's equivalents to Makefiles are in a proprietary format and may not be suitable for an open source project MinGW (also known as MinGW32) Consistency with the UNIX build procedure No need to install full Cygwin Can be run on a Linux host as a cross-compiler to build Windows executables Cross compiling with Cygwin When GCC is invoked under Cygwin, it will typically make a binary that links with CYGWIN1.DLL, using the Cygwin runtime to do things like I/O and emulation of some parts of the C library that are not provided by the Windows API.
How To Install Ganglia
However, it is not mandatory to use GCC in this way. By passing the -mno-cygwin option to GCC, it can be forced to build a binary that does not link with CYGWIN1.DLL. This has various benefits:. Cygwin licensing constraints are avoided. Only Ganglia license applies. Less likelihood of problems on systems having multiple copies of CYGWIN1.DLL installed on the hard disk. No exposure to security issues in CYGWIN1.DLL, reducing the risk of a costly re-deployment of the application in a large enterprise.
Implementation steps This list is not meant to be complete, and is currently considered a work in progress. Please feel free to add suggestions:. Modify configure.in to include an option for the Windows native build. George harrison living in the material world.
Modify configure.in to add -mno-cygwin to CFLAGS when doing a Windows native build. Inclusion of any necessary header files for Windows (or provide a script that simplifies the process of finding these files on the local hard disk).

Investigate any C library functions that are not provided natively, and include an appropriately licensed alternative in gmond, re-implement the function, or modify gmond so that it doesn't use the function. Development of metric module implementations using WMI.
Creation of MSI file for the Windows installer C library issues. POSIX threads - resolved in trunk Linking issues. libConfuse must be linked statically. metric modules - can these be dynamically linked?. metric modules for WMI must be C, gmond in trunk supports C metric modules.
APR on Windows - static or dynamic? Replacing #ifdef CYGWIN The CYGWIN compiler variable may need to be complemented with some additional variables: #define OSWINDOWS 'set if compiling either Windows variant, Cygwin or native #define CYGWIN' set if compiling without -mno-cygwin #define WINNATIVE // set if compiling on MinGW, Visual C or CYGWIN with -mno-cygwin.

Generally, a download manager enables downloading of large files or multiples files in one session. Many web browsers, such as Internet Explorer 9, include a download manager. Stand-alone download managers also are available, including the Microsoft Download Manager. If you do not have a download manager installed, and still want to download the file(s) you've chosen, please note:. You may not be able to download multiple files at the same time. In this case, you will have to download the files individually. (You would have the opportunity to download individual files on the 'Thank you for downloading' page after completing your download.).
Files larger than 1 GB may take much longer to download and might not download correctly. You might not be able to pause the active downloads or resume downloads that have failed. The Microsoft Download Manager solves these potential problems. It gives you the ability to download multiple files at one time and download large files quickly and reliably. It also allows you to suspend active downloads and resume downloads that have failed. Microsoft Download Manager is free and available for download now.
Ever since system administrators have been in charge of managing servers and groups of machines, tools like monitoring applications have been their best friends. You will probably be familiar with tools like, and Centreon. While those are the heavyweights of monitoring, setting them up and fully taking advantage of their features may be somewhat difficult for new users. In this article we will introduce you to Ganglia, a monitoring system that is easily scalable and allows to view a wide variety of system metrics of Linux servers and clusters (plus graphs) in real time. Ganglia Mobile Friendly Summary View Summary In this article we have introduced Ganglia, a powerful and scalable monitoring solution for grids and clusters of servers. Feel free to install, explore, and play around with Ganglia as much as you like (by the way, you can even try out Ganglia in a demo provided in the project’s.
While you’re at it, you will also discover that several well-known companies both in the IT world or not use Ganglia. There are plenty of good reasons for that besides the ones we have shared in this article, with easiness of use and graphs along with stats (it’s nice to put a face to the name, isn’t it?) probably being at the top.
But don’t just take our word for it, try it out yourself and don’t hesitate to drop us a line using the comment form below if you have any questions.
Install Windows 7 On Windows 10 Computer
Hi all, I'm trying to install Ganglia on my CentOS 7 machines. Specifically, these machines make up a Hadoop cluster. I've added the RPMForge repository to my yum lists, and I've jumped through all of those necessary hoops to get the package installed. When I execute a 'yum search ganglia', it never shows up. After extensive Googling, I've determined that Ganglia only seems to be on CentOS 6 repositories. I could hypothetically download all of the RPM files and install them (and their dependencies) by hand, I honestly don't have enough time to do that, and I don't want to clutter up my OS installation with potentially unneeded packages. The packages I want to install are:.

ganglia. ganglia-gmond. ganglia-gmetad.
ganglia-web ganglia-web seems to be the problem child. While I can install most things just fine using the regular RPMs and installing a few dependencies here and there, ganglia-web depends on Zend Framework (version 1), and installing that seems to be its own entirely different rabbit hole. I guess what I'm asking is: how can I install Ganglia on CentOS 7 without having to install a bunch of dependencies manually? Thanks in advance. Edit: formatting.
Slurm is an open-source workload manager designed for Linux clusters of all sizes. It’s a great system for queuing jobs for your HPC applications. I’m going to show you how to install Slurm on a CentOS 7 cluster. Delete failed installation of Slurm. Install MariaDB. Create the global users. Install Munge.
Install Slurm. Use Slurm Cluster Server and Compute Nodes I configured our nodes with the following hostnames using these.
Our server is: buhpc3 The clients are: buhpc1 buhpc2 buhpc3 buhpc4 buhpc5 buhpc6 Delete failed installation of Slurm I leave this optional step in case you tried to install Slurm, and it didn’t work. We want to uninstall the parts related to Slurm unless you’re using the dependencies for something else. First, I remove the database where I kept Slurm’s accounting. Yum remove mariadb-server mariadb-devel -y Next, I remove Slurm and Munge. Munge is an authentication tool used to identify messaging from the Slurm machines. Yum remove slurm munge munge-libs munge-devel -y I check if the slurm and munge users exist.
Cat /etc/passwd grep slurm Then, I delete the users and corresponding folders. Userdel - r slurm userdel -r munge userdel: user munge is currently used by process 26278 kill 26278 userdel -r munge Slurm, Munge, and Mariadb should be adequately wiped. Now, we can start a fresh installation that actually works. Install MariaDB You can install MariaDB to store the accounting that Slurm provides.
If you want to store accounting, here’s the time to do so. I only install this on the server node, buhpc3. I use the server node as our SlurmDB node. Yum install mariadb-server mariadb-devel -y We’ll setup MariaDB later. We just need to install it before building the Slurm RPMs.
Create the global users Slurm and Munge require consistent UID and GID across every node in the cluster. For all the nodes, before you install Slurm or Munge: export MUNGEUSER=991 groupadd -g $MUNGEUSER munge useradd -m -c 'MUNGE Uid 'N' Gid Emporium' -d /var/lib/munge -u $MUNGEUSER -g munge -s /sbin/nologin munge export SLURMUSER=992 groupadd -g $SLURMUSER slurm useradd -m -c 'SLURM workload manager' -d /var/lib/slurm -u $SLURMUSER -g slurm -s /bin/bash slurm Install Munge Since I’m using CentOS 7, I need to get the latest EPEL repository. Yum install epel-release Now, I can install Munge. Yum install munge munge-libs munge-devel -y After installing Munge, I need to create a secret key on the Server.
My server is on the node with hostname, buhpc3. Choose one of your nodes to be the server node.
First, we install rng-tools to properly create the key. Yum install rng-tools -y rngd -r /dev/urandom Now, we create the secret key. You only have to do the creation of the secret key on the server. /usr/sbin/create-munge-key -r dd if=/dev/urandom bs=1 count=1024 /etc/munge/munge.key chown munge: /etc/munge/munge.key chmod 400 /etc/munge/munge.key After the secret key is created, you will need to send this key to all of the compute nodes.
Scp /etc/munge/munge.key [email protected]:/etc/munge scp /etc/munge/munge.key [email protected]:/etc/munge scp /etc/munge/munge.key [email protected]:/etc/munge scp /etc/munge/munge.key [email protected]:/etc/munge scp /etc/munge/munge.key [email protected]:/etc/munge Now, we SSH into every node and correct the permissions as well as start the Munge service. Chown -R munge: /etc/munge/ /var/log/munge/ chmod 0700 /etc/munge/ /var/log/munge/ systemctl enable munge systemctl start munge To test Munge, we can try to access another node with Munge from our server node, buhpc3. Munge -n munge -n unmunge munge -n ssh 3.buhpc.com unmunge remunge If you encounter no errors, then Munge is working as expected. Install Slurm Slurm has a few dependencies that we need to install before proceeding. Yum install openssl openssl-devel pam-devel numactl numactl-devel hwloc hwloc-devel lua lua-devel readline-devel rrdtool-devel ncurses-devel man2html libibmad libibumad -y Now, we download the latest version of Slurm preferably in our shared folder.
The latest version of Slurm may be different from our version. Cd /nfs wget If you don’t have rpmbuild yet: yum install rpm-build rpmbuild -ta slurm-15.08.9.tar.bz2 We will check the rpms created by rpmbuild. Cd /root/rpmbuild/RPMS/x8664 Now, we will move the Slurm rpms for installation for the server and computer nodes. Mkdir /nfs/slurm-rpms cp slurm-15.08.9-1.el7.centos.x8664.rpm slurm-devel-15.08.9-1.el7.centos.x8664.rpm slurm-munge-15.08.9-1.el7.centos.x8664.rpm slurm-perlapi-15.08.9-1.el7.centos.x8664.rpm slurm-plugins-15.08.9-1.el7.centos.x8664.rpm slurm-sjobexit-15.08.9-1.el7.centos.x8664.rpm slurm-sjstat-15.08.9-1.el7.centos.x8664.rpm slurm-torque-15.08.9-1.el7.centos.x8664.rpm /nfs/slurm-rpms On every node that you want to be a server and compute node, we install those rpms. In our case, I want every node to be a compute node. Yum -nogpgcheck localinstall slurm-15.08.9-1.el7.centos.x8664.rpm slurm-devel-15.08.9-1.el7.centos.x8664.rpm slurm-munge-15.08.9-1.el7.centos.x8664.rpm slurm-perlapi-15.08.9-1.el7.centos.x8664.rpm slurm-plugins-15.08.9-1.el7.centos.x8664.rpm slurm-sjobexit-15.08.9-1.el7.centos.x8664.rpm slurm-sjstat-15.08.9-1.el7.centos.x8664.rpm slurm-torque-15.08.9-1.el7.centos.x8664.rpm After we have installed Slurm on every machine, we will configure Slurm properly. Visit to make a configuration file for Slurm.
I leave everything default except: ControlMachine: buhpc3 ControlAddr: 128.197.116.18 NodeName: buhpc1-6 CPUs: 4 StateSaveLocation: /var/spool/slurmctld SlurmctldLogFile: /var/log/slurmctld.log SlurmdLogFile: /var/log/slurmd.log ClusterName: buhpc After you hit Submit on the form, you will be given the full Slurm configuration file to copy. On the server node, which is buhpc3: cd /etc/slurm vim slurm.conf Copy the form’s Slurm configuration file that was created from the website and paste it into slurm.conf.
We still need to change something in that file. Underneathe slurm.conf “# COMPUTE NODES,” we see that Slurm tries to determine the IP addresses automatically with the one line. NodeName=buhpc1-6 CPUs = 4 State = UNKOWN I don’t use IP addresses in order, so I manually delete this one line and change it to. # slurm.conf file generated by configurator easy.html. # Put this file on all nodes of your cluster.
# See the slurm.conf man page for more information. PartitionName = debug Nodes = buhpc 1 - 6 Default = YES MaxTime = INFINITE State = UP Now that the server node has the slurm.conf correctly, we need to send this file to the other compute nodes.

Scp slurm.conf [email protected]/etc/slurm/slurm.conf scp slurm.conf [email protected]/etc/slurm/slurm.conf scp slurm.conf [email protected]/etc/slurm/slurm.conf scp slurm.conf [email protected]/etc/slurm/slurm.conf scp slurm.conf [email protected]/etc/slurm/slurm.conf Now, we will configure the server node, buhpc3. We need to make sure that the server has all the right configurations and files. Mkdir /var/spool/slurmctld chown slurm: /var/spool/slurmctld chmod 755 /var/spool/slurmctld touch /var/log/slurmctld.log chown slurm: /var/log/slurmctld.log touch /var/log/slurmjobacct.log /var/log/slurmjobcomp.log chown slurm: /var/log/slurmjobacct.log /var/log/slurmjobcomp.log Now, we will configure all the compute nodes, buhpc1-6.
We need to make sure that all the compute nodes have the right configurations and files. Mkdir /var/spool/slurmd chown slurm: /var/spool/slurmd chmod 755 /var/spool/slurmd touch /var/log/slurmd.log chown slurm: /var/log/slurmd.log Use the following command to make sure that slurmd is configured properly. Slurmd -C You should get something like this: ClusterName=(null) NodeName=buhpc3 CPUs=4 Boards=1 SocketsPerBoard=2 CoresPerSocket=2 ThreadsPerCore=1 RealMemory=7822 TmpDisk=45753 UpTime=13-14:27:52 The firewall will block connections between nodes, so I normally disable the firewall on the compute nodes except for buhpc3. Systemctl stop firewalld systemctl disable firewalld On the server node, buhpc3, I usually open the default ports that Slurm uses: firewall-cmd -permanent -zone=public -add-port=6817/udp firewall-cmd -permanent -zone=public -add-port=6817/tcp firewall-cmd -permanent -zone=public -add-port=6818/tcp firewall-cmd -permanent -zone=public -add-port=6818/tcp firewall-cmd -permanent -zone=public -add-port=7321/tcp firewall-cmd -permanent -zone=public -add-port=7321/tcp firewall-cmd -reload If the port freeing does not work, stop the firewalld for testing. Next, we need to check for out of sync clocks on the cluster. On every node: yum install ntp -y chkconfig ntpd on ntpdate pool.ntp.org systemctl start ntpd The clocks should be synced, so we can try starting Slurm!
On all the compute nodes, buhpc1-6: systemctl enable slurmd.service systemctl start slurmd.service systemctl status slurmd.service Now, on the server node, buhpc3: systemctl enable slurmctld.service systemctl start slurmctld.service systemctl status slurmctld.service When you check the status of slurmd and slurmctld, we should see if they successfully completed or not. If problems happen, check the logs! Compute node bugs: tail /var/log/slurmd.log Server node bugs: tail /var/log/slurmctld.log Use Slurm To display the compute nodes: scontrol show nodes -N allows you to choose how many compute nodes that you want to use.
