The Logfile Navigator, lnav for short, is a curses-based tool for viewing and analyzing log files. The value added by lnav over text viewers or editors is that it takes advantage of any semantic information that can be gleaned from the log file, such as timestamps and log levels. Using this extra semantic information, lnav can do things like interleaving messages from different files, generate histograms of messages over time, and provide hotkeys for navigating through the file. These features are meant to allow the user to quickly and efficiently focus on problems.

Among the list of metrics are time to login, index usage, bufferpool hit rate, query cache hit rate, slow queries, temp tables on disk, table cache hit rate, connected threads, and many more. Requirements are either a DBD::mysql Perl module or a MySQL client package.
NOC Project is an Operation Support System (OSS) for telecom companies, service providers, and enterprise Network Operation Centers (NOC). Areas covered by NOC include fault management, performance management, service activation/provisioning, knowledge base, multi-VRF address space management (IPAM), multi-vendor configuration management, DNS provisioning, peering management, RPSL and BGP filter generation, and reporting.
The dsnapshot script provides a high-level interface to the Linux Logical Volume Manager. It uses its block-level snapshot support to create directory snapshots. In contrast to block-level snapshots, directory snapshots resemble the file system layer. Thus, you can snapshot any directory that is on a logical volume without worrying about the actual logical volumes, mount points, and paths.

The MyCAT project is a toolset for managing MySQL/Linux servers, and could be helpful for anyone managing a network of *nix servers whether running MySQL Cluster, standard replication, or not running MySQL at all. At present, it contains three programs. rcall eases use and administration of groups (clusters) of *nix servers by creating logical groupings and a single location from which to run commands on all servers while entering it only once. It requires only an SSH connection. rep_mon is a replication monitor that notifies if a server is lagging or has encountered any errors. It handles any replication topology easily. binlog_mon monitors disk space used by MySQL binary logs, purging only when disk space is needed. It checks all slaves to ensure that purged files are not still being read by slaves. It has configurable behavior in the event that a slave still needs the oldest file.
BitNami MAPPStack is an easy-to-install, ready-to-run binary distribution of Apache, PostgreSQL, and PHP, including the phpPgAdmin tool.
