Log watcher is a PHP class that polls log files and takes newly added lines to send them to a given watcher email address. Although this class can be used to poll any type of log files, it was developed with the intention to overcome a limitation of the PHP error trapping system that is not able to capture certain types of errors during script execution, like script parsing errors or form file uploading failures. It is meant to be used from cron-like task schedulers to poll log files regularly. The email notification message can be composed from text templates. The message delivery function can be replaced by custom functions like the urgent mail function that can be faster for delivering critical messages.
Alerttail monitors a given file and executes a list of actions when a user-defined text pattern has been written to the file. For example, the user can pop up a GTK notification window when a certain message is written to a log file. Actions can be alerttail built in actions (GTK notify action, geoipLocalization action, or filtering text action) or a custom user defined shell command action. A Qt 4 GUI frontend helps with configuration.
Sysload SP Analyst offers powerful means to control and analyze server performance. It provides real-time, continuous, fine-grained resource monitoring across Windows, Solaris, AIX, HP/UX, Linux, I-series, Citrix, Netware, and virtual machines (VMware Vi, IBM LPARs, Solaris X, I5 OS LPARs). It also provides incident and failure risk prediction and immediate analysis of the root cause of problems, allowing you to pinpoint the application(s) or user(s) responsible for server load increases.
