Open Source Logging Software

smartmontools contains utility programs (smartctl, smartd) to control/monitor storage systems using the Self-Monitoring, Analysis and Reporting Technology System (S.M.A.R.T.) built into most modern ATA and SCSI disks. It is derived from smartsuite.

Ndbtop is a curses based lightweight tool for monitoring a MySQL Cluster / NDB system. Ndbtop constantly monitors the Cluster and provides access to simple operations.

DBD2 inserts database records from TCP input. It is a companion project to Syslgod2 and an application in its own right. It ships with a backgrounding client for generic use. The client sends whatever information the user puts on the command-line to the back-end daemon via TCP. Upon successful transmission, the client exits. On failure, it backs off and retries until its life-time timer expires. The back-end daemon accepts data from Syslogd2 or its own client and inserts that data (and envelope information) into one or more databases using MySql client library or dbi drivers (also on SourceForge). The client needs no configuration (all input is via command-line). It is intended for hosts to make database entries without needing database client or interface code. Syslogd2 integration allows DBD2 to act as Syslogd2's database back-end for MySql and other databases supported by the dbi drivers. Original purpose was to track Linux cluster job status but other uses exist.

Distributed event bus library for passing application events to listeners running anywhere on the network. Library is a lightweight wrapper over the JGroups toolkit with event filtering features.

A set of tools which provide advanced interaction with processes on win32 systems. Like: Starting processes with redirected streams, altered priority, returning pid in exitcode, timeout, killing processes by pid.

Command line tool that can view multiple log files remotely and blend them into a single output based on the appropriate dates within the log files themselves. Has cat and tail modes available. Support for multiple local/remote protocols

bWatch - Linux cluster monitoring software.

Log4j is great, but when you run your application over a cluster of machines and transactions have to be merged over mutliple files the mess begins. This log4j-Modules shall solve it by providing an "on demand" cluster consolidation.
