Open Source JavaScript Logging Software

This is a Node.js module available through the npm registry. Installation is done using the npm install command. Create a new morgan logger middleware function using the given format and options. The format argument may be a string of a predefined name, a string of a format string, or a function that will produce a log entry. The format function will be called with three arguments tokens, req, and res, where tokens is an object with all defined tokens, req is the HTTP request and res is the HTTP response. The function is expected to return a string that will be the log line, or undefined / null to skip logging. Write log line on request instead of response. This means that a requests will be logged even if the server crashes, but data from the response (like the response code, content length, etc.) cannot be logged. To define a token, simply invoke morgan.token() with the name and a callback function.

WhoisUP v0.3 monitors hosts via ICMP and shows the status in a web page. When a host is down, the script can send mail, syslog message, open a popup message or play a sound. Moreover, the script monitors if the host exceed the latency threshold limit. The script uses NMap to send ICMP packets and to save the host status into an XML file. Then, WhoisUP reads the XML and shows the report in a web page with AJAX features; in case of host failure the script can send alarms. WhoisUP is useful to monitor hosts (PC, Server, NAS, Router, Switch and so on...) and to receive alerts when a host go down.

Fancy output with fallback for minimal environments. Consistent command-line interface (CLI) experience. Spam prevention by throttling logs. console uses std in the underlying so calling wrapStd redirects console too. The benefit of this function is that things like console.info will be correctly redirected to the corresponding type. Any instance of consola that inherits the mocked instance, will apply provided callback again. This way, mocking works for withTag scoped loggers without the need for extra effort. Choose between one of the built-in reporters or bring in your own one. By default FancyReporter is registered for modern terminals or BasicReporter will be used if running in limited environments such as CIs. A reporter (class or object) exposes log(logObj) method. To get more info about how to write your own reporter, take a look at the linked implementations.

It comes with Web interface to search and generate chart accordingly. This project is Open Source project with Apache 2.0 license for allowing you to extra development on top of Log Searcher project. The initial configuration was written on readme.txt before implementation on production line. If you have idea for improvement, you can drop an email to me. Contact: log.searcher[at]yahoo.com

Logger for Redux. Now maintained by LogRocket! LogRocket is a production Redux logging tool that lets you replay problems as if they happened in your own browser. Instead of guessing why errors happen or asking users for screenshots and log dumps, LogRocket lets you replay Redux actions + state, network requests, console logs, and see a video of what the user saw. Transform action before print. Eg. convert an Immutable object to plain JSON. Transform state before print. Eg. convert an Immutable object to plain JSON.

This is a web application, using thing application user can see the log file with multiple search critria. This application supports Log4J and log4Net. This tool is used to filter the log file, based on multiple criteria. Admin user can configure multiple applications and group the application up to three levels. Application name will be displayed in tree structure based upon grouping. Application will be displayed based on roles. System will allow the user to filter the log file not only the application level and also in group level (Multiple groups or multiple application and group). This tool will allow creating multiple users with different role in this system.

PVLng is a manufacturer independent system for saving operating data of photovoltaik plants.

Hackable and configurable to the core, signale can be used for logging purposes, status reporting, as well as for handling the output rendering process of other node modules and applications. You can now support the development process through GitHub Sponsors. To create a custom logger define an options object yielding a types field with the logger data and pass it as argument to a new signale instance. By utilizing the secrets option, secrets and other sensitive information can be filtered out from the body as well as the metadata, i.e. scope names etc, of to-be-logged messages. The option is part of the configuration object passed to a Signale instance on its initialization, and is of type Array<String|Number>. The array can hold multiple secrets, all of which are removed, if present, from the to-be-logged messages and are replaced with the default '[secure]' string.

When logging, it's important to use the least amount of resources available. Over time, logged messages tend to pile up. This can lead to some negative effects on applications, such as reduced requests per second. This is why pino is an ideal choice for logging. pino is a very fast Node.js logger with very low overhead. It is in many cases 5x faster than alternatives, based on benchmarks. pino offers not just speed but a number of great features as well, such as a browser API, child loggers, transports, and pretty printing, which "prettifies" your logs.
