Adventures in logging – Unhandled expression
After working on the SÅzu HTTP reverse proxy for a while, I came up with an interesting approach to logging. Now why would I come up with my own logger, when there are existing solutions in Rust? Mainly, log and slog. That logging library grew up from testing things out with log, and changing requirements along the way. Beginning with log and env_logger Like a lot of other Rust developers, I start

Its core idea is to quickly analyze and view we
Search logs using Fluentd and Kibana - Go ahead!
Search logs using Fluentd and Kibana Apr 17th, 2013 | Comments Fluentd is a flexible and robust event log collector, but Fluentd doesn’t provide own datastore and Web UI. So if you want to search stored events, then you can use Kibana and ElasticSearch :) ElasticSearch is a easy to use Search Engine and Kibana is a great Web UI for ElasticSearch with LogStash format.

log.io - Real-time log monitoring in your browser
How does it work? Inputs watch log files for changes, send new log messages to the server, which broadcasts to web clients. Log messages are tagged with stream and source information based on user configuration. log.io has no persistence layer. File inputs are informed of file changes via inotify, and log messages hop from input to server to web client via TCP and socket.io, respectively. Simple T
MultiTail
General info What is it in short? MultiTail follows files in style, it is tail on steroids. Can you elaborate on that? MultiTail lets you view one or multiple files like the original tail program. The difference is that it creates multiple windows on your console (with ncurses). It can also monitor wildcards: if another file matching the wildcard has a more recent modification date, it will automa
