Benefits of the unified collection of real-time logs:1. Quickly locate the problem machine in the cluster2, no need to download the entire log file (often relatively large, download time is much)3, the log can be countedA, to find the most frequently occurring anomalies, for tuning processingB, Statistics crawler IPC, Statistical user behavior, do cluster analysis, etc.Based on the above requirements, I adopted the ELK (Elasticsearch + Logstash + kibana
The front-end time wrote an essay log4net. NOSQL +elasticsearch implements logging , because of project reasons need to integrate log root Java platform colleague integration using Logstash+kibana+elasticsearch+redis structure to achieve log statistics analysis, Therefore, a component that outputs Log4net logs to Redis is required. Did not find the ready-made, do it yourself. Reference to the log4net. NOSQL Code.Redis's C # client uses Servicestack

1. Architecture for highly available scenarios
In the previous article using Elasticsearch+logstash+kibana+redis to build a log management service describes the overall framework of log services and the deployment of various components, this article mainly discusses the Log service framework of high-availability scenarios, mainly from the following three aspects of consideration: As
SummaryWhen we use Logsatsh to write the configuration file, if we read too many files, the matching is too much, will make the configuration file hundreds of thousands of lines of code, may cause reading and modification difficulties. At this time, we can put the configuration file input, filter, output in a different configuration file, or even the input, filter, output again separated, put in a different file.At this time, the later need to delete and change the contents of the
