    Cacti On An ISPConfig Server Within 10 Easy Steps In this article I describe how to install and setup the Cacti in a ISPConfig Server. Cacti is a complete network graphing solution designed to harness the power of RRDTool's data storage and graphing functionality. There aren't many differences from installing in other ISP Managers or standalone Apache installations. I tried many others solutions, but Cacti is very simple and fast to implement.

  • Server Monitoring With munin And monit On Mandriva 2010.0

    Server Monitoring With munin And monit On Mandriva 2010.0 In this article I will describe how you can monitor your Mandriva 2010.0 server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

    Trafficanalysis Using Debian Lenny By using my Network Monitoring Appliance we noticed a link in MRTG always under heavy load. On this link a lot of different traffic aggregates, so we decided to analyze of what quantities of protocols and therefore applications the cumulative traffic consists.

  • Network Monitoring Appliance

    ubuntu Author: gbiTags: , , Comments: 9

    Network Monitoring Appliance My ambition was to implement a small (better tiny) appliance for monitoring network health and network resources, short and longtime trends, running under VMware Server or VMware ESX. So I had an eye upon all components which are implemented on the system, to be as leightweight as possible. This was also the reason why no SQL DBMS based software was used. The appliance is based on Ubuntu Jeos LTS (8.04.3 at the time of this writing). Almost all used components are from the related repositories. This tutorial shows how the appliance was implemented.

  • Monitoring Multiple Log Files At A Time With MultiTail On Debian Lenny

    debian Author: Falko TimmeTags: , Comments: 0

    Monitoring Multiple Log Files At A Time With MultiTail On Debian Lenny MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). It can also monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automatically switch to that file. That way you can, for example, monitor a complete directory of files. Merging of two or even more log files is possible.

    Monitoring Network Latency With Smokeping (Ubuntu 9.04) This guide shows how to install and configure Smokeping on Ubuntu 9.04 to monitor network latency. From the Smokeping web site: "SmokePing is a deluxe latency measurement tool. It can measure, store and display latency, latency distribution and packet loss.

    Network Management With OpenNMS OpenNMS is an opensource enterprise network management tool. It helps network administrators to monitor critical services on remote machines and collects the information of remote nodes by using SNMP. OpenNMS has a very active community, where you can register yourself to discuss your problems. Normally openNMS installation and configuration takes time, but I have tried to cover the installation and configuration part in a few steps.
