moreThis article was originally posted on SigNoz Blog and is written by Selvaganesh NGINX is a prominent web server reverse proxy server and mail proxy utilized by many websites and applications to serve content to their users One important aspect of managing a web server is logging which refers to the process of recording information about the server s activity and performance In NGINX logging is done using the error log and access log directives error log directive specifies the file where NGINX should log errors access log directive specifies the file where NGINX should log information about incoming requests and responses What are Nginx Error Logs The error log directive is typically used to log information about errors and other important events that occur on the server This can include messages about failed requests issues with the server configuration and other issues that may require attention An example of an error log is shown in the picture below Nginx Error log example What are Nginx Access Logs The access log directive on the other hand is used to log information about incoming requests and responses This can include details such as the IP address of the client making the request the URL of the requested resource the response status code and the size of the response An example of access logs is shown in the picture below Nginx Access log exampleNGINX logs can be useful for various purposes including tracking the server s performance identifying potential issues or errors and analyzing the usage patterns of the server However managing logs can also be challenging as they can quickly grow in size and become difficult to manage In this tutorial we will illustrate the following How to configure Nginx access logsHow to configure Nginx error logsHow to send Nginx logs to SyslogCollecting and analyzing Nginx logs with SigNozLet s get started PrerequisitesDockerNginx Installing Nginx Installing NGINX on Linuxsudo apt updatesudo apt install nginxTo start NGINXservice nginx start Installing NGINX on MacYou can install NGINX on Mac using Homebrew brew install nginxTo start NGINX brew services start nginx You can then access your NGINX server on localhost Go to http localhost and you should see a screen like the one below NGINX server running on localhost Configuring NGINX to generate access logsLet s go ahead and make the necessary changes to the nginx conf file in order to change the location and structure of the logs By default NGINX logs all incoming requests to the access log file in the var log nginx directory The format of the log entries in this file is defined by the log format directive in the NGINX configuration file Let s define the custom Nginx log pattern to the nginx conf file in the directory etc nginx nginx conf as shown below log format logger json escape json source nginx message nginx log captured time time iso resp body size body bytes sent host http host address remote addr request length request length method request method uri request uri status status user agent http user agent resp time request time upstream addr upstream addr When configuring the server s access logs we provide the preferred log format logger json in a server directive Make a log format with the name and pattern shown below http sendfile on tcp nopush on tcp nodelay on keepalive timeout types hash max size log format logger json escape json source nginx message nginx log captured time time iso resp body size body bytes sent host http host address remote addr request length request length method request method uri request uri status status user agent http user agent resp time request time upstream addr upstream addr include etc nginx mime types default type application octet stream Logging Settings access log home user Work logs access log logger json A list of available variables can be found here Restart the Nginx for the config to take effect sudo service nginx restartNote The nginx config path for Mac OS will be under usr local etc nginx So please ensure to update the config properly Go to url http localhost and now look at the access log file Every line in the access log file which is in home user Work logs access log has one log record One example of a log record is shown below source nginx message nginx log captured time T resp body size host address request length method GET uri status user agent PostmanRuntime resp time upstream addr You can view the access log file through the terminal using the cat command as shown below access log file which generates Nginx logsThe next step is to send these logs to the SigNoz platform Configuring NGINX to generate error logsTo enable the error log choose the log level and log file location Using the error log directive in the nginx conf configuration file you may select the log level as shown below error log home user Work logs nginx error log emerg error log home user Work logs nginx info log info There are several levels of error logging that you can use to specify the types of errors that should be logged These log levels are debug Debug level messages are very detailed and are typically used for debugging purposes info Information level messages are used to log important events such as the start and stop of the Nginx server notice Notice level messages are used to log events that are not necessarily error conditions but are worth noting warn Warning level messages are used to log potential error conditions that may require attention error Error level messages are used to log actual error conditions that have occurred crit Critical level messages are used to log very severe error conditions that may require immediate attention alert Alert level messages are used to log conditions that require immediate action emerg Emergency level messages are used to log conditions that are so severe that the Nginx server may be unable to continue running You need to reload the nginx configuration for these changes to take effect You can do this by running the command service nginx restart Nginx error log configuration Sending NGINX logs to SyslogSyslog is a standard for logging system events It is used to record and store the log messages produced by various system components including the kernel system libraries and applications Syslog provides a centralised method for managing and storing log messages making it easier to monitor and resolve system issues To collect syslog from Nginx you will need to configure Nginx to send its log messages to syslog Add the following line to the configuration file replacing syslog server hostname with the hostname or IP address of your syslog server error log syslog server syslog server hostname facility local tag nginx severity error access log syslog server syslog server hostname facility local tag nginx severity debug Save the configuration file and restart Nginx Now Nginx will send its log messages to the syslog server which can be accessed and analyzed as needed There are several options that you can use to customize the way that Nginx sends syslog messages Here are a few examples facility This option specifies the facility to which the log message should be sent The facility is used to categorize log messages and can be used to filter log data on the syslog server Common facilities include local through local user daemon and system tag This option specifies a tag to be added to the log message The tag can be used to identify the source of the log message and can be used to filter log data on the syslog server severity This option specifies the severity level of the log message Common severity levels include emerg alert crit error warning notice info and debug Note The above configuration will send only error messages to syslog If you want to send other log levels e g info warning etc you can adjust the severity parameter in the configuration line To configure syslog on the signoz platform refer this documentation NGINX Logging and Analysis with SigNozSigNoz is a full stack open source APM that can be used for analyzing NGINX logs SigNoz provides all three telemetry signals logs metrics and traces under a single pane of glass You can easily correlate these signals to get more contextual information while debugging your application SigNoz uses a columnar database ClickHouse to store logs which is very efficient at ingesting and storing logs data Columnar databases like ClickHouse are very effective in storing log data and making it available for analysis Using SigNoz for NGINX logs can make troubleshooting easier SigNoz comes with an advanced log query builder live tail logs and the ability to filter log data across multiple fields Let us see how to collect and analyze Nginx logs with SigNoz Installing SigNozSigNoz may be installed in three simple steps on macOS or Linux PCs using a simple install script Docker Engine is installed automatically on Linux by the installation script However before running the setup script on macOS you must manually install Docker Engine git clone b main https github com SigNoz signoz gitcd signoz deploy install shYou can visit the documentation for instructions on how to install SigNoz using Docker Swarm and Helm Charts Deployment Docs Steps for collecting Nginx logs into SigNozModify the docker compose yaml file present inside deploy docker clickhouse setup to expose to mount the log file to otel collector The file is located here Mount the path where the Nginx access logs are available Work logs access log tmp access log to docker volume otel collector image signoz signoz otel collector command config etc otel collector config yaml user root required for reading docker container logs volumes otel collector config yaml etc otel collector config yaml var lib docker containers var lib docker containers ro highlight next line Work logs access log tmp access logHere we are mounting the log file of our application to the tmp directory of SigNoz otel collector You will have to replace  lt path gt with the path where your log file is present Add the filelog reciever to otel collector config yaml which is present inside deploy docker clickhouse setup and include the path tmp access log receivers filelog highlight next line include tmp access log start at beginning operators type json parser timestamp parse from attributes time layout Y m dT H M S z type move id parse body from attributes message to body type remove id time field attributes timeNext we will modify our pipeline inside otel collector config yaml to include the receiver we have created above service logs highlight next line receivers otlp filelog processors batch exporters clickhouselogsexporter Once the changes are made we need to restart the OTel Collector container to apply new changes Use the command docker compose restart Check if all the containers are running properly by using the command docker ps Check if all the containers are running properlyWe can now go to the URL http localhost and generate some Nginx logs into the access logGo to the SigNoz URL click on the Logs tab and look for the word nginx http localhost Nginx logs sent to SigNozClick on the individual log to get a detailed view Details of individual Nginx logsYou can also view the logs in JSON format Nginx logs in JSON format ConclusionNGINX logs provides useful information to debug Nginx web servers By using the error log and access log directives you can track the performance and usage of your server and identify potential issues or errors The error log directive can give you information about all errors and you can use these logs to identify exactly what went wrong The access log directive gives you information about HTTP requests received by the Nginx server and other client information like IP address response status code etc While debugging a single Nginx server by directly accessing Nginx logs can be done it s often not the case in production Managing multiple Nginx servers and troubleshooting them effectively requires a centralized log management solution In case of server downtime you need to troubleshoot issues quickly and effective dashboards around Nginx monitoring is needed With SigNoz logs you can effectively manage your Nginx logging You can check out its GitHub repo now
