InfoHub Main Configuration File


The InfoHub configuration file used to configure the ULFM Reference Implementation. For uptime, it defines InfoDict Items Load01, Load05, and Load15 to store load averages, and Days to store up days. There are two subscriptionsa??PatchMe to send a notification when Days is greater than 30 and DontBeLazy to send a notification when Load15 is less than 1. For log files, it defines an InfoDict Item called Anything to hold the value of line read from each log file. For this item, it defines two subscriptionsa??AuthFail to send an alert when Anything contains ([) "Fail" and GTMError to send an alert when Anythingcontains ([) "%GTM-E".

FileLine Gleaner


A simple FileLine gleaner program that reads every line of the /var/log/messages and /var/log/auth.log and returns value in the form of 9999:line_read_value. Note that 9999 is the InfoDict Id for msg. PreExpr gets invoked before processing the log file and defines configuration options and PostExpr gets invoked after completion of log file processing and removes configuration options defined in PreExpr.

PipeLine Gleaner


A simple PipeLine gleaner program for the uptime command. It returns values in the multiples of <key>:<value> in the form of 3030400:Days :3030401:Load:3030405:Load5:3030415:Load15 for every line read from the uptime output. PreExpr gets invoked prior before processing uptime and defines configuration options. PostExpr gets invoked after completion of uptimeprocessing and removes configuration options defined in PreExpr. InfoHub invokes the UptimeGleaner every 15 seconds.
