The System Data Recorder has a collection part, or the part that handles recording the data from each system, and a reporting side where it permanently stores and generates simple reports and graphs. For some configurations, it can use only the recording part without the reporting side at all. The data recorder consists of many simple utilities developed in Korn and Perl that extract different telemetry from the Solaris kernel statistic module. Some recorders gather their data from various processes directly using OS or third party utilities. There are 5 recorders that should be installed and deployed in any system, and optional recorders needed only in certain cases: CMT and JVM.
Nall is a small status icon application that discreetly fits into the system tray. Its purpose is to spawn a list of user scripts periodically and display one line of output per script in a tooltip window. Thus, it is possible to "monitor" any kind of event that can be detected with a script. Nall does not care about the return values of the scripts it runs, but only displays their output. It is also easy to interface nall with Nagios plugins.
Seetxt is a lightweight text file and man page viewer for X windows. It maintains "document meta-data" for each user, allowing them to automatically keep bookmarks and highlights for read-only system files. It also has a "server mode" so that command line requests can be sent to a single running server rather than starting multiple instances. Other features include hypertext-style apropos (man page) searches, file monitoring, multi-level regular expression searching, a command history, and nice little toggle lights on the interface for the server and file monitor. There's also cross-application drag-n-drop support, and handy little features that allow you to view the output of shell commands and process the text buffer with an external command (sed, awk, grep, perl, etc.) Seetxt is POSIX compliant.
Tweeter is another command line script that can update your Twitter status from the command line. It also uses the SSL link to protect your username and password. Tweeter can only post a new status; it cannot follow anyhone, send direct messages, or anything else. The username and password are not stored on the file system, so you can post to different accounts with ease. It should also work on older machines.
jmxsh is a fully scriptable command-line JMX client based on Tcl. It is simply a Tcl interpreter powered by Java/Tcl (with command-line history and editing provided by JLine) that has special command-line options for connecting to JMX servers and special Tcl commands for interacting with JMX servers. jmxsh is capable of simultaneously connecting to multiple JMX servers. There's also a "browse mode" for exploring the remote JMX namespace without knowing beforehand the names of MBeans or their properties. jmxsh and all its dependencies are distributed in a self-contained executable jar file for ease of use.
