System monitoring software: sar, ksar |
vote
|
|
| sar is one of the old and famous commandline utilities, which is often overlooked. It provides a wealth of information when you have kind of performance bottlenecks. By itself it only provides lengthy columns of numerical data, kind of hard to interpret. sar exists on most Linux distributions, for example Ubuntu, Debian, CentOS, Gentoo, and is also available on Solaris, AIX, and other commercial Unices. ksar, on the other hand, is a Java based front end for sar's numerical data. It produces friendly graphs which could be exported to .pdf and some other formats. read more... |

Monitoring Linux and Unix Server Temperatures with Opsview |
vote
|
|
| Managing power consumption in a Datacenter is a key factor in helping keep overall business energy costs down and ensuring servers are running at optimum performance. Overheating can lead to increased costs for cooling and also runs the risk of servers crashing. Opsview server monitoring software can be used to check and alert on server temperature and also the temperature of individual components within a server (Memory, CPU and Hard drives). Thresholds and alerts can be set for when critical temperatures are exceeded, helping to keep hot-running servers in check. This blog post details how to configure Opsview to monitor the temperature of Linux and Unix servers. read more... |

Remote MySQL Monitoring |
vote
|
|
| There may be the situation that you have to monitor a MySQL server remotely. There are some linux tools to do performance and query monitoring locally, and these tools can also used to monitor remotely - but only unencrypted! Also often MySQL is only listening on the loopback interface, so it is even not reachable remotely over the net (which is very good seen from the security viewpoint). But there is an easy solution in the Linux world. read more... |

| This guide provides an overview on how to set up umbrella monitoring to monitor applications and devices in distributed networks. Multiple instances of monitoring systems (in this example Verax NMS express) can be configured in a tree-like, master-slave, federated umbrella monitoring structure. This umbrella-like monitoring can be used to monitor geographically distributed networks e.g. by telecommunications operators to manage regional, state and national networks or managed service providers for managing their clients' infrastructure. read more... |

Zabbix: a free network monitoring tool (pdf) |
vote
|
|
| Zabbix is (free of cost) software that monitors numerous parameters of a network and the servers on that network. Zabbix is a useful tool for monitoring the health and integrity of servers. A flexible notification mechanism allows users to configure e-mail based alerts for virtually any event, allowing fast reaction to server problems. All monitored parameters are stored in a database. Zabbix offers excellent reporting and data visualisation features based on the stored data, making Zabbix useful for capacity planning. Zabbix supports both polling and trapping. All Zabbix reports and statistics, as well as configuration parameters, are accessed through a web-based frontend. The web-based front end means that the health of your servers can be assessed from any location.Properly configured, Zabbix can play an important role in monitoring IT infrastructure for companies with even hundreds of servers to monitor. Zabbix offers: - support for both polling and trapping mechanisms
- agents (client software) for Linux (HP-UX, AIX, FreeBSD, OpenBSD) and Windows 2000, XP, NT
- server software for Linux and Unix
- secure user authorisation
- two user groups: "Administrators" and "Zabbix users"
- web-based interface for viewing and configuration
- flexible e-mail notification of predefined events

Server Monitoring with munin, monit on Debian 6 |
vote
|
|
| In this article I will describe how you can monitor your Debian Squeeze 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, and a watchdog that ensures the availability of the monitored services. read more... |

Isn't as pretty as Zenoss or as streamlined as Nagios, but it really is a SysAdmins tool. It doesn't hide functions away from you or gloss over details to make you feel nurtured, its all out there gritty and raw for you to use an manipulate. There is a nature learning curve in wrapping your head around the concepts of "items" and "triggers" and how you can combine them in really powerful ways, but before long you'll be frustrated by the limits of other solutions. read more... |

| After reading this two-part series, a systems administrator should feel empowered to run Ganglia and Nagios to really monitor his data center as never before. The scope of these two packages is enormous. What we have touched on here though is relevant to a cluster, grid, or cloud infrastructure. In Part 2, learn how to install and configure Nagios to watch hosts and services, alerting users when things go wrong. The article also shows you how to unite Nagios with Ganglia (from Part 1) and add two other features to Nagios for standard clusters, grids, and clouds to help with monitoring network switches and the resource manager. read more... |
