Sphinx VS prometheus

Sphinx - https://sphinxsearch.com

Sphinx is a search engine that can be integrated into a website to provide advanced search functionality such as full-text, Boolean, and faceted search. It is a powerful open-source search engine that can handle large amounts of data and quickly return results.

Have been using Sphinx. It does some processing around suffixes, tenses, and so on, and looks at word proximity (BM25), but is definitely limited.

Lucene is the thing you think you need. Elastic Search is a nice wrapper for it. But these are Java, so maybe you want Sphinx Search (C++) or MeiliSearch (Rust).

Using a natural language search will almost certainly be a better solution and PHP may not be the best tool for this task. Figure out how you are going to get the text out of the PDF and where you are going to put it. Look at things like sphinx and full text search in boolean mode for doing the keyword matching.

In practice though you don't do any of this, you get a library to do it for you. I've used Sphinx Search in the past for some fairly hefty (In the order of terabytes), and there's a good book covering how to get it all set up and started.

Five years ago Manticore began as a fork of an open source version of the once popular search engine Sphinx Search. We had two bags of grass, seventy-five pellets of mescaline, three C++ developers, a support engineer, a power user of Sphinx Search / backend team lead, an experienced manager, a mother of five helping us part-time, and a ton of bugs, crashes, and technical debts. So we got a shovel and other digging tools and started working to get it up to the search engine industry standards. Not that Sphinx was impossible to use, but many things were missing, and existing features weren’t quite stable or mature. And we had pushed it about as far as we could. So after 5 years and hundreds of new users, we’re ready to say that Manticore Search can be used as an alternative to Elasticsearch for both full-text search and (now) data analytics too.

Finally if you really want a full fledged solution the most popular are good old Sphinx http://sphinxsearch.com or Apache Solr https://solr.apache.org but as these take a bit of time to setup I'd make sure that's truly needed. Chances are unless your collection is the size of the Library of Congress you are probably fine with ripgrep on your own indexes as text or some R package or sqlite FTS5 extension https://www.sqlite.org/fts5.html

An old fact from 2014 December 12th was significant for Vinted: the company switched from Sphinx search engine to Elasticsearch 1.4.1. At the time of writing this post, we use Elasticsearch 7.15. Without a doubt, a lot has happened in between. This chapter will focus on Elasticsearch metrics, we will share our accumulated experiences from four generations of collecting metrics.

It's like Prometheus, but for logs. Okay it's not really to do with the Norse or Greek gods, instead Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by the open source project Prometheus. Built by Grafana Labs, Loki is designed for ease of use. Instead of indexing the contents of the logs, Loki provides a set of labels for each log stream. The latest update includes query acceleration with Bloom filters, native OTel support, Helm charts, and more. Check out the changelog for all the major changes and deprecations.

Developers widely use Prometheus as a system for operational monitoring and alerting for their projects. Here is a list of tools for monitoring frontend services with Prometheus.

Just to give an example of the power of Go for CLI builds, you may have already used or at least heard of Docker, Kubernetes, Prometheus, Terraform, but what do they all have in common? They all have a large part of their usability via CLI and are developed in Go 🐿.

Distributed system administrators need mechanisms and tools for monitoring individual nodes in order to analyze the system and promptly detect anomalies. Developers also need effective mechanisms for analyzing, diagnosing issues, and identifying bugs in protocol implementations. Logging, tracing, and collecting metrics are common observability techniques to allow monitoring and obtaining diagnostic information from the system; most of the explored code bases use these techniques. OpenTelemetry and Prometheus are popular open-source monitoring solutions, which are used in many of the explored code bases.

Setting up monitoring for a system, especially one involving GRPC communication, provides crucial visibility into its operations. In this guide, we walked through the steps to instrument both a GRPC server and client with Prometheus metrics, exposed those metrics via an HTTP endpoint, and visualized them using Grafana. The Docker-Compose setup simplified the deployment of both Prometheus and Grafana, ensuring a streamlined process.

Alerting and Notification: Select a tool with flexible alerting mechanisms to proactively detect anomalies or deviations from defined thresholds. Consider asking questions like "Does this tool offer customizable alerting options and support notification channels that suit our team's communication preferences?" A tool like Prometheus provides robust alerting capabilities.

Prometheus

Prometheus is an open-source monitoring and alerting toolkit. It is designed to monitor highly dynamic containerized systems, making it an excellent choice for monitoring Docker containers and Kubernetes clusters.
