The complexity of todayâ€™s emerging technologies complicates IT infrastructure management and its ability to ensure the servers, or network, that host or reinforce these applications run smoothly and perform within acceptable limits. As business grows, it often becomes difficult to predict when a hardware upgrade is required, or what part of your server/network need optimization etc.
Our experts provide you recommendations, and help setup various server and network monitoring solutions for you so that your team can monitor your IT resources and provides timely alerts, enabling you to immediately respond to any unforeseen event and to plan capacity efficiently before time.
Nagios is an open source IT Infrastructure Monitoring software that watches hosts and services. It offers complete monitoring and alerting for servers, switches, applications, and services. Nagios is free software and supported to run under Linx and its variants. Nagios is comprised of the following Nagios Agents and it watches hosts and services.
- NRPE – Nagios Remote Plugin Executor (NRPE)
- NRDP – Nagios Remote Data Processor (NDRP)
Zabbix is an open source and free network management system designed to monitor and analyze various network services, servers and network hardware. Zabbix can check the status of standard services without installation of any software on the host using standard services such as HTTP and SNMP. Monitoring is done via SNMP, TCP and ICMP, IPMI, JMX, SSH, telnet and using custom parameters. Zabbix also allow installation of agent on UNIX and Windows hosts and can monitor CPU load, network utilization, disk space, etc. Zabbix provides support for various databases to store data such as MySQL, PostgreSQL, SQLite, Oracle or IBM DB2.
Zenoss is an IT infrastructure (application, server and network) management application that provides detail operational awareness of network, physical servers, virtual servers, and applications. The project was started by Erik Dahl and has two variations namely Zenoss Core and Zenoss Enterprise. Zenoss Core is the open source version of the same software and is sponsored by Zenoss Inc. Zenoss Enterprise is targetted for Enterprise with all the bells and whistles and is based on the Zenoss Core.
Argus is an open source system and network monitoring application with a web interface. It monitor all network infrastructure resources such as network services, servers and all relevant hardware and send alerts on encountering problem. The software is coded in the Perl language and support both IPv4 and IPv6.
Ntop is a network traffic probe based on libcap that provides insight to network usage and provides network traffic statistics accessible via a web browser. It displays a list of current hosts in the network and give information concerning the IP (Internet Protocol) and Fiber Channel (FC) traffic generated. Ntop is available for both windows and Linux. It supports the following protocols .
MRTG (Multi Router Traffic Grapher) developed by Tobi Oetiker is a free software for monitoring, analyzing and measuring traffic load for network devices. MRTG was initially focused to monitor routers but has now evolved into a sophisticated tool for creating graphs and statistics for almost anything. MRTG provides results in Graphs. MRTG is available for Unix/Linux, Windows and even Netware systems.
Munin is a network/system monitoring and more of a performance gauging software that provides insight and analysis in resource trends. Resources can range from computers, networks, SANs to applications. Munin support a master/node architecture in which master is responsible for connecting to each slave regularly and retrieve data. Munin have about 400 plugins available and its output is presented in graphs through a web interface. Munin is targeted to be easy with plug n play capabilities, resulting in its popularity among administrators.
Cacti is an open-source network monitoring and graphing tool built as a frontend to RRDTool. Cacti graph the resulting data and stores all the necessary information required for generation. Cacti features include a fast poller, graph templating, data acquisition methods, SNMP support and is completely PHP driven. Cacti’s comprehensive features and an easy to use web interface make it a nice choice for LAN-sized installations up to complex networks.
Observium is a PHP/MySQL/SNMP based Network Observation and Monitoring System, it collects information automatically from various devices and provide result using a web interface. Observium is based on three design principles minimum interaction, maximum automation and maximum accessibility of information. Observium was designed to work in compliment with other industry standard opensource projects such as Nagios, Mon, GeSHi, RANCID, and jpgraph software etc and add more value to its existing features. Observium supports the following vendors Dell, Cisco, Linux, FreeBSD, Juniper, Brocade, Foundry, HP.
BB or Big Brother is software for systems and network monitoring widely popular among the classic generation of system administrators. It is considered as one of the first monitoring systems to use a web based interface. BB focus was to provide system and network status information in an easy way using web as the medium. Instead of using SNMP based notification, BB relies on a client-server model and its own network communication protocol. BB support redundancy, failover and allows network resources to be tested from distributed locations. Big Brother provides the ability to monitor, trend and alert on various network resources such as Windows servers, UNIX servers, Linux servers, web servers, websites, VM’s, network devices, databases, applications, and any device with an IP address. BB is available as a free software evaluation for 3o days and an enterprise version.
Ganglia is a free and open source monitoring system for computing systems such as clusters and Grids. It is based on a hierarchical, scalable and distributed architecture. Ganglia allow to remotely monitoring live or historical network and system statistics (such as CPU load averages or network utilization) for all machines at a very low per-node overheads and high concurrency. Ganglia use existing technologies such as XML, XDR and RRDTool for various functions. Ganglia is the de-facto standard for thousands of cluster monitoring around the world and can handle clusters with 2000 nodes. Ganglia is available for various operating systems and processor architectures.
