NGINX logs & metrics provide critical information about the requests the web server is out as well as application errors. In order to effectively manage a NGINX web server, it is necessary to get feedback about the activity and performance of the server as well as any problems that may be occurring.
Loom systems enables you to identify application and service performance issues in your code, server failures and abnormal traffic streams that may affect customer experience while improving your organization security and compliance.
With Loom Systems you get deep-level visibility into each of your web server process and running application errors. When problems are detected, the Loom systems anomaly-detection engine correlates between the different services and responses to identify the root causes.
Real time detection of performance bottlenecks such as failures, redirections, errors, and traffic volume.
Monitor real user performance without code changes, Correlate events with the rest of your application layers. (e.g. SQL database).
Stronger Compliance, easy drill down issues in complex user transactions through the Analytics.
NGINX logs contain critical data on your users. The right analysis of your NGINX logs & metrics can help you move from reactive to proactive. Loom Systems detects anomalies (deviations from the established baseline) and flags exceptions in real-time to help you identify real and potential threats. When you use Loom Systems as an Apache security log analytics, you will automatically receive alerts containing:
Abnormal user activities in the organization assets.
Identify the agents, ports and protocols typically used.
Receive real time alerts based on behavioral changes.
PCI compliance looks at your organization’s security and infrastructure from many different perspectives, one of which is PCI DSS requirement 10: “Track and monitor all access to network resources and cardholder data.”
The purpose of this requirement is to ensure access to your credit card holding systems are monitored at all times, and that in the event of a breach, access and events can be thoroughly traced and blocked. Maintaining 12 months of logs and quickly searching those logs is an enormous task, especially when viewing your entire portfolio of disparate systems across multiple environments, potentially around the world.
NGINX logs & metrics provide a record of access and events to help proactively identify suspicious user behavior and strengthen your security posture. Once your logs streamed to Loom, you will be automatically notified of events specific to your PCI environment.
NGINX is the heart of the modern web, powering half of the world’s busiest sites and applications. NGINX is open source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. It started out as a web server designed for maximum performance and stability. As Nginx is a high-speed, lightweight HTTP server engine, more and more websites and applications are moving to Nginx. The performance improvements for serving static content can be significant. Especially at high loads, Nginx is faster than other solutions and consumes less server resources.
In addition to its HTTP server capabilities, NGINX can also function as a proxy server for email (IMAP, POP3, and SMTP) and a reverse proxy and load balancer for HTTP, TCP, and UDP servers.
Further details about logging and nginx server can be found here.
NGINX writes information about encountered issues of different severity levels to the error log. By default, the error log is located at logs/error.log (the absolute path depends on the operating system and installation), and messages from all severity levels above the one specified are logged.Access Log
NGINX writes information about client requests in the access log right after the request is processed. By default, the access log is located at logs/access.log, and the information is written to the log in the predefined combined format.
The Nginx Access Log common format contains the following metrics:
remote_addr – IP from which request was made
remote_user – HTTP Authenticated User. *This will be blank for most apps as modern apps do not use HTTP-based authentication.
timestamp –as per server timezone
request – HTTP request type GET, POST, etc + requested path without args + HTTP protocol version
status – HTTP response code from server
body_bytes_sent – size of server response in bytes
response_time - response time of each user request.
http_referer – Referral URL (if present)
http_user_agent – User agent as seen by server
To override the default setting, use the log_format directive to change the format of logged messages, as well as the access_log directive to specify the location of the log and its format.
Just configure Rsyslog to see the all events you need. NGINX writes information about application encountered issues and user activities performance. The rsyslog utility is a standard for computer message logging and allows collecting log messages from different devices. In NGINX, logging to rsyslog is configured with the syslog: prefix in error_log and access_log directives.
